Indicators of reduced engine power and increased fuel consumption can confuse the driver and create the impression of a major problem, while the real cause may simply be dirty fuel injectors. So, can cleaning them really restore your car’s performance?
Fuel injector cleaning is the process of removing carbon deposits, varnish, and microscopic contaminants that accumulate inside the fuel injectors over time.
These injectors are responsible for spraying fuel with high precision into the combustion chamber, and even a very slight blockage directly affects engine performance, fuel consumption, and throttle response.
Added to the fuel tank and work while driving. Effective for light clogging and suitable as preventive maintenance.
Injectors are removed and connected to a specialized machine that pumps strong cleaning fluid under pressure. This is the most effective method.
Cleaning solution is sprayed directly into the injector after removal. Suitable for moderate clogging.
Diesel injectors are more sensitive and require specialized equipment because they operate at much higher pressure than gasoline injectors.
Yes. Blockage restricts fuel delivery, and after cleaning, engine power is noticeably restored.
Yes. Improvements can reach up to 10% according to leading automotive sources.
They are effective only for light clogging and do not replace professional cleaning.
Yes. If they are old, severely clogged, or internally rusted, they may require replacement.

Car brand logos are the badges and names each manufacturer places on the front grille, the boot lid and the centre of the steering wheel, and the easiest way to learn them is to group them by country of origin: Japanese badges such as Toyota's three ovals, Korean ones such as Hyundai's slanted H, and Chinese brands, many of which spell out their full name in Latin letters, alongside German, European and American badges. In this guide you will find each brand's name as it is written and said, a short description of its badge, its meaning where it is documented, and a table for quick comparison.
A car badge (the logo or emblem) is the trademark that identifies the manufacturer, and it usually appears in several places:
Badges fall into two types: a standalone symbol such as a star, rings or a lion, or a name spelled out in letters, as with many American and new Chinese brands, and knowing this difference helps you recognise a car from a distance.
Japanese badges are very familiar on the Kingdom's roads, and most are simple symbols that are easy to remember:
Chinese cars have become familiar in the Saudi market, and their best-known badges include:
Many Chinese brands have appeared in recent years, some cannot be recognised from the badge alone, and here are practical ways to tell them apart:
European badges often rely on old symbols with well-known stories:
American badges tend towards written names and simple shapes:
A quick summary of each brand's badge:
| Brand | Country of origin | Badge description |
| Toyota | Japan | Three ovals |
| Nissan | Japan | Name inside a thin circle |
| Honda | Japan | Upright letter H |
| Mitsubishi | Japan | Three red diamonds |
| Hyundai | Korea | Slanted H in an oval |
| Kia | Korea | The word KIA in a sharp script |
| Changan | China | V shape inside a circle |
| Chery | China | A-like symbol in an oval |
| Jetour | China | Name in Latin letters |
| Haval | China | HAVAL in large letters |
| MG | Britain (Chinese owner) | MG inside an octagon |
| BYD | China | The letters BYD |
| Mercedes-Benz | Germany | Three-pointed star in a circle |
| BMW | Germany | Circle with blue and white quarters |
| Audi | Germany | Four interlinked rings |
| Volkswagen | Germany | VW letters in a circle |
| Peugeot | France | Lion |
| Ford | USA | Blue oval |
| Chevrolet | USA | Gold bowtie |
| GMC | USA | Red GMC letters |
Car brand logos become easier to remember when you link each badge to its country and parent company, read the name written on the boot when in doubt, and check the registration card and the VIN before any purchase decision. You can browse the cars available at Saleh Cars Group to get to know the different brands and models.

Vehicle driving authorization on Absher is an electronic service that lets a vehicle owner add an authorized person to drive the vehicle inside or outside the Kingdom, depending on the type of authorization selected. The owner starts from Vehicles, then Manage Vehicles, selects the vehicle, chooses Authorize Vehicles and then Issue Authorization. Before that, the vehicle registration must be valid with active insurance, and both parties must have Absher accounts. This guide covers the conditions, steps, period limits, the difference from ownership transfer and what the owner should check first.
The official Issue an Authorization service page on the National Portal says the service allows you electronically to add an authorized person to drive a vehicle inside or outside the Kingdom, depending on the selected type of authorization. The service belongs to the Ministry of Interior, targets individuals, both citizens and residents, and lists its channels as the website portal and the iOS and Android apps.
The authorization is therefore permission to drive, not a sale or a transfer of ownership. The vehicle owner issues the authorization, and the authorized person is added to drive within the selected type and period. Read the service name in your account carefully and do not confuse it with other vehicle services in the same menu.
The Prerequisites tab of the official service page lists the following conditions, as shown at the time of writing:
The Required Documents tab lists the following:
The text we reviewed adds no other conditions, so follow what the service requests for your case rather than lists circulating in forums or messages.
The following steps come from the official service page. Menus may look different in the portal and the app, so look for the same names:
The page describes the service duration as immediate, but do not rely on pressing the issue button alone; review what the service displays after submission to confirm the transaction is complete. If a message prevents issuing the authorization, return to the conditions above and start with the item the message refers to, such as insurance validity or the validity of one of the licenses, instead of retrying without changing anything.
The page states that the authorization applies inside or outside the Kingdom depending on the type of authorization you select in the final step. Decide the purpose before you start: will the authorized person drive only inside the Kingdom, or do they need to drive the vehicle abroad?
For an external authorization, the Required Documents tab requires the authorized person to hold an exit and re-entry visa. The page links the visa duration to the authorization period, but the Prerequisites wording (the authorization period must not exceed the visa duration) runs in the opposite direction to the Required Documents wording (the visa must not exceed the authorization period), so follow what the service accepts for your case. A holder of a final exit visa cannot be added as an authorized person.
The service page does not address the requirements of other countries or border crossings when travelling by car, so ask the competent authorities about this before relying on the authorization alone.
The service page does not set a fixed authorization period; it sets upper limits instead. The period must not exceed the validity of the vehicle registration, the validity of the authorized person’s driving license, or the duration of their exit and re-entry visa if they hold one. In practice, whichever of these dates expires first limits the period you can choose.
As for cancellation, the pages we reviewed do not explain the steps. Start from the Authorize Vehicles screen in the owner’s account and review the options shown to you. If nothing fits your case, ask the official Ministry of Interior support channels, and do not rely on an unofficial explanation that mentions a specific button or period.
If the vehicle registration is about to expire, review the vehicle registration renewal steps on Absher before choosing the authorization period, because the period may not exceed the registration validity.
Some people confuse allowing someone to drive the car with selling it to them. As the service describes it, authorization adds an authorized driver and is issued by the vehicle owner, while ownership transfer is a separate procedure that changes the owner. The table summarises the difference:
| Item | Driving Authorization | Ownership Transfer |
| Purpose | Add an authorized person to drive the vehicle | Transfer vehicle ownership to another owner |
| Who starts it | The vehicle owner, according to the service page | According to the sale service conditions |
| Does the owner change? | The service describes no change of ownership | Yes, that is the purpose of the procedure |
| Period limits | Not beyond the registration and the authorized person’s driving license validity | Follows the transfer service conditions |
If your aim is to sell or buy the car, authorization is not a substitute for a sale; review the Absher ownership transfer steps and sale conditions to complete the correct procedure.
The official conditions determine whether the authorization can be issued, but they do not answer every practical question. Before issuing it, review the following points:
If an accident happens while the authorized person is driving, learn the steps to take after a car accident and Najm reporting. The service page does not address how responsibility for accidents or violations is shared between the owner and the authorized person, so do not build assumptions on it; ask the competent authority or your insurer about your case.
Yes. The Required Documents tab states that the authorizer must be the vehicle owner. The authorization is therefore not issued from the account of someone who does not own the vehicle, even if they usually drive it.
Yes. The page requires both the authorizer and the authorized person to have Absher accounts. Confirm this before starting so the process does not stop when you enter the details.
No. The prerequisites state that authorization cannot be granted to someone holding a final exit visa. For a holder of an exit and re-entry visa, the authorization period is tied to the visa duration.
The published condition is a valid vehicle registration with active insurance. If either has expired, resolve it first and then return to the authorization service.
The service page mentions insurance only as a condition for issuing the authorization. Review your policy and its terms with your insurer before allowing another person to drive.
Vehicle driving authorization on Absher starts from the owner’s account and requires a valid registration, active insurance and Absher accounts for both parties, with its period limited by the validity of the licenses and visa. Choose the right authorization type, review your insurance policy and do not use authorization as a substitute for ownership transfer.

Overheating without coolant loss is possible: coolant visible in the reservoir does not prove that it circulates through the engine or releases heat effectively. The fault may involve coolant flow, airflow or cooling controls, and the temperature reading itself may also need checking. If an overheating warning appears, stop somewhere safe, switch off the engine and request assistance. Do not keep driving because the reservoir looks full.
The everyday expression water level refers here to engine coolant, not a recommendation to use plain water. This article focuses on a level that appears normal despite an overheating warning. For the wider picture, see the guide to engine overheating causes and what to do.
The reservoir’s role and the method for reading its level depend on the cooling-system design: it may be a pressurized part of the system or a recovery tank. Coolant also expands when hot, so comparing a hot reading with a cold one cannot establish system health. A visual reading within the marks on a cold engine, following the manual, tells you only about the level. It does not prove that passages are free of air or restrictions, or rule out a fault or a leak whose effects are not yet apparent.
The cooling system must move heat away from the engine and then transfer it to the air through the radiator. A failure at either stage can raise the temperature without an obvious drop in level. These are possibilities for inspection, not a shopping list of replacement parts:
For an explanation of circulation specifically, read about the water pump’s role in circulating coolant. Mentioning the pump does not make it the most likely cause in your car, and replacing it without checking the rest of the system may not solve the problem.
Record only the conditions you already observed during previous use. Do not drive again or leave the engine running to reproduce overheating. The pattern can help a workshop organize its checks, but it is not a conclusive diagnosis:
| Previous observation | What might the technician check? | What does it not prove? |
| Temperature rises at a stop and eases when moving | Airflow, fan performance and fan control | It does not prove that only the fan is faulty |
| The warning appears on the highway or uphill | Coolant flow and heat exchange under load | It does not identify the pump or radiator specifically |
| It began after a coolant change or repair | Correct filling, trapped air and connections | It does not confirm trapped air without checks |
| It coincides with air conditioning use | Cooling performance as load and airflow change | It does not prove low AC refrigerant |
If the connection with AC use is your main observation, there is a separate explanation of engine overheating when the air conditioning is on. The key point here is that a normal coolant level cannot rule out a cooling fault, whatever the conditions when the warning appears.
A temperature sensor, its wiring or the display system may affect the reading. However, do not assume the warning is false because the reservoir is full or you cannot see steam. Some cooling faults show no obvious external sign at first. Treat the warning seriously until a qualified technician verifies the actual temperature and readings.
The technician compares diagnostic data and appropriate measurements with the vehicle’s specifications and operating conditions. A fault code alone cannot condemn a part, and the absence of a code does not prove that cooling is normal. There is also no single operating temperature for every car. Use the owner’s manual and vehicle-specific service information to interpret the gauge and warning message.
Once the engine has cooled completely, you may record the level visible from outside the reservoir if this is possible and safe according to the manual, without removing caps or parts. A normal level or a warning that disappears after shutdown does not establish that the fault has gone or that continuing the journey is safe.
Tell the technician when the warning appeared: while stopped, climbing or travelling. Mention any preceding service work or fluid addition. Describe the message and any smell or steam you noticed from a safe position. Photograph the dashboard only after stopping, and do not reproduce the fault for documentation.
If initial checks do not identify the cause, broader diagnosis may be necessary. Do not jump to a head-gasket diagnosis, or rule it or another internal fault out solely because the reservoir level is stable. Testing should determine the next step.
If the level is within the correct limits, adding fluid will not repair a fan or restore impaired flow, and may exceed the permitted fill level. Use coolant meeting the vehicle’s specification and the concentration stated in the manual. Plain water is not a universal substitute, and color alone does not establish compatibility. Read about coolant differences and choosing a suitable fluid for more context.
Do not mix unknown products or experiment with additives to treat overheating. Flushing and air removal are not identical procedures on every vehicle; leave them to a professional when technically justified. Maintaining the correct level matters, but it is only one part of system health, not a replacement for checking performance.
Not necessarily; it depends on the system design and condition. The visible level alone does not prove correct filling or circulation, and never justifies opening a hot cap.
No. Leakage is not the only possible sign of a pump fault. Its ability to circulate coolant needs appropriate assessment, not just a look underneath the car.
A lower reading does not prove the fault has gone. After an overheating warning, do not resume driving to test the car; request assistance and inspection before using it again.
Do not remove the thermostat as an experiment: it is part of cooling regulation. A technician should assess it and fit the correct replacement if necessary.
No. The overheating can be real despite a stable level. Do not ignore the warning or disconnect the sensor; have the reading and system performance checked together.
A stable coolant level neither rules out overheating nor identifies its cause. Stop safely at a warning, switch off the engine, avoid hot caps and fans, and give your observations to a qualified technician. A sound repair starts with evidence of the fault, not extra water or random parts replacement.

Vehicle ownership transfer in Saudi Arabia is done electronically through the vehicle sale service on the Absher platform, without visiting traffic offices: the seller enters the buyer's ID number and date of birth, the agreed sale price and the seller's bank account; the buyer then receives a notification of the request within one hour and accepts or declines it, transfers the price through Absher's secure payment system, insures the vehicle and pays the fees, and once the car is received, checked and the delivery is confirmed on Absher, ownership is officially transferred. Both parties must be registered on Absher, the vehicle registration (istimara), periodic inspection and insurance must be valid, and there must be no violations on the buyer or the vehicle.
The Ministry of Interior offers the vehicle sale service through the Absher platform, and the National Platform describes it as a service that enables individuals to sell their private vehicles and transfer ownership electronically after its dues are cleared, after reaching an agreement with the buyer and completing all required procedures, including vehicle inspection to ensure compliance with conditions, registering the vehicle under the buyer's identity, and issuing the vehicle registration license.
Procedures and conditions may be updated from time to time, so confirm the latest steps on the Absher platform or the National Platform before you start.
Before the seller starts the request, both parties should review the conditions listed on the service page on Absher, as failing to meet any of them may stop the sale:
The page also mentions limits on the number of vehicles of certain types that a resident may own, so review them on Absher if the buyer is a resident. If the periodic inspection is close to expiring, prepare the car early using the checklist on how to prepare your car for the periodic inspection.
After agreeing with the buyer on the price and other terms, the seller starts the request with these steps, as set out by the National Platform:
Ownership does not pass to the buyer until they complete their steps on the platform, which according to the National Platform are:
The table below summarises the role of each party at every stage of the sale:
| Stage | Seller | Buyer |
| Before starting | Agree on the price and terms, and check the istimara, periodic inspection and insurance are valid | Register on Absher and make sure there are no violations on them |
| Creating the request | Enter the buyer's ID, date of birth, price and bank account, then confirm | Wait for the Absher notification |
| Responding | Wait for acceptance or refusal | Review the details and accept or decline the request within one hour |
| Payment | Receive the price in the bank account entered in the request | Transfer the price through Absher's secure payment system |
| Insurance and fees | The platform lists no step for the seller at this stage | Insure the vehicle and pay the government fees and Absher fees |
| Delivery | Hand the vehicle over to the buyer after they accept the sale | Receive and check the vehicle, then confirm delivery on Absher |
If you are handing your car over to a family member, Absher has a separate service called vehicle ownership transfer between family members, which allows vehicle ownership to be waived between family members electronically once the current owner and the new owner agree. The National Platform lists its steps as follows:
The platform organises the procedure, but it does not replace inspecting the car yourself; the service page on Absher states that the sale takes place after the vehicle has been viewed and inspected and the seller and buyer have agreed. Here are practical tips before accepting the request:
Transferring car ownership through Absher is a clear process if you prepare for it: check the conditions, agree on the price, inspect the car before accepting, pay through the platform's secure payment system, and do not confirm delivery before checking the car. If you are looking for your next car, you can browse the cars available at Saleh Cars Group.

Vehicle registration renewal is available electronically through Absher vehicle services once the service requirements are met and the automated eligibility check is passed. Start by reviewing insurance, technical inspection and any required payments, then select the vehicle, choose registration renewal and confirm the transaction. Istimara means the vehicle registration here, not the person’s driving licence. This guide explains what to prepare and how to handle a renewal that cannot proceed, without confusing renewal with ownership transfer or an inspection booking.
Renewal extends the registration of a previously registered vehicle. The official vehicle registration renewal page on the National Portal explains that the service is available electronically through Absher without visiting traffic offices, and that eligibility is checked automatically against the service requirements. Reaching the vehicle screen therefore does not establish that renewal is complete.
When checking an expiry date, first identify the document: a driving licence relates to the driver, while vehicle registration relates to the vehicle. This distinction matters when researching requirements; do not apply driving licence renewal conditions to registration renewal. Follow the service name shown in your account rather than an old screenshot of a different menu.
The official service page lists the following requirements. Use them as a checklist before starting, while also referring to what the service displays for your vehicle when you apply. A receipt or an old copy of a document is not a substitute for checking its validity and that it relates to the intended vehicle.
The required-documents tab also specifies an existing vehicle registration. This guide does not add requirements to upload photographs or other documents simply because somebody else encountered them; follow what the service actually requests. Because renewal eligibility is checked automatically, verify availability in your account rather than deciding based on a date quoted in an unofficial explanation.
Start with insurance: open the policy details and check that the policy is valid and covers the same vehicle. To distinguish the type of cover from the validity of a policy, read about comprehensive versus third-party car insurance. Choosing cover that fits your needs is different from checking a renewal requirement; the name of the cover alone does not establish that an application will be accepted.
Next, review the inspection certificate. If you need to prepare for an appointment, use the periodic vehicle inspection preparation checklist to organise technical checks, not as proof of passing. Inspection is a separate process with its own result, not a renewal-screen button that substitutes for a valid certificate.
Then review violations and any payment requirements displayed. The guide to checking, paying and disputing traffic violations explains the related services. Do not confuse filing a dispute with satisfying the renewal payment requirement; rely on the displayed status and the relevant authority’s instructions rather than assuming another action removed the obstacle.
The following route follows the official service instructions. Read the details on each screen before moving on. If the menus appear in a different order in your interface, look for vehicle registration renewal under vehicle services rather than selecting another service because its name is similar.
Payment alone, or closing the screen, does not prove successful renewal. If your session ends before the result appears, return to the vehicle details and check what actually happened before repeating the steps. The aim is to confirm that the correct vehicle’s registration was updated, not simply to complete a sequence of clicks.
These services may relate to the same vehicle, but each serves a different purpose. Use the table to identify your starting point, then review the relevant service conditions separately. Do not assume completing one also completes another.
| Procedure | Purpose | What Does Not Prove Completion? |
| Registration renewal | Renew the vehicle registration | Buying insurance or booking an inspection alone |
| Ownership transfer | Transfer the vehicle to another owner | Registration renewal alone |
| Technical inspection | Inspect the vehicle and obtain its result | An appointment without the inspection taking place |
If your aim is to sell or buy the vehicle, review the Absher ownership transfer steps and sale conditions instead of treating renewal as a substitute for transfer. Organise your notes under separate headings: registration status, insurance status, inspection result and transfer transaction status when relevant. This helps avoid confusing different documents.
An unmet published requirement is a possible reason renewal cannot proceed, but it does not explain every message. Start with the text displayed in your account and review the item it identifies, rather than repeating the request or changing several things without understanding the issue.
When contacting support, explain where the process stopped and which documents you checked. Never share your password or verification code, and hide personal details in any screenshot you post. This is a way to organise follow-up, not a guarantee of processing time or acceptance.
In short, prepare the vehicle requirements, renew the registration through Absher and verify the result. If the process cannot proceed, address the item identified in the message or request official clarification, without assuming fees, deadlines or exceptions that the service does not show.

Driving license renewal in Saudi Arabia is done electronically through the Absher platform under traffic services, without visiting traffic offices, provided you complete the regulatory requirements such as paying the fees and completing a medical examination. This electronic service covers private driving licenses and motorcycle licenses only, and the remaining validity of the license must be less than 365 days. This guide explains the requirements as shown on the official service page at the time of writing, the renewal and delivery steps, why a request may not proceed, and how it differs from renewing the vehicle registration (Istimara).
The driving license renewal page on the National Portal describes a service that lets individuals renew their driving license electronically, easily and efficiently, without visiting traffic offices. It lists the service duration as immediate and the delivery channels as the website portal and smartphone apps. The Absher service guide defines the beneficiary as a citizen or resident who is registered and activated on the Absher platform.
So first make sure your Absher account is active and that you can log in, then check your license type. According to the prerequisites tab, the service covers renewing private driving licenses and motorcycle licenses only. If your license is of another type, do not assume this service will accept it; ask the official traffic channels about the right procedure for your case.
The official service page lists the following requirements. Use the table as a checklist before logging in to Absher, while following what the service displays for your case when you apply. Requirements may be updated, and the service page at the time you apply is the reference.
| Requirement as Shown on the Service Page | What to Check Before Starting |
| A private or motorcycle driving license | The license type recorded in your details |
| Payment of license renewal fees through government payments via banks | That payment was actually made for the correct service, not just that a payment screen was opened |
| Payment of traffic violations, if any | The status of any violations recorded against you before applying |
| Remaining license validity of less than 365 days | Your expiry date, using the driving license information service |
| A medical examination through a certified medical center | That the examination was done at a certified center |
The required documents tab repeats payment of any violations, payment of the renewal fees and the medical examination, and does not mention uploading photos or extra papers. Do not rely on circulated lists that add unpublished documents. If you have violations, review how to check and pay traffic violations before starting the renewal.
The following steps are taken from the service page on the National Portal. If the menus look different in your interface, look for the driving license renewal service under traffic services, and do not choose a similarly named service such as vehicle registration renewal.
Note that the payment inside these steps is for delivery. For the renewal fees themselves, the prerequisites tab says they are paid through government payments via banks. This guide does not state amounts for any period; follow what the service shows for your case. Before filling in the address, make sure your National Address is correct, because it is used for the license delivery request.
Closing the screen or completing a payment alone does not prove the renewal is complete. Check for the success message, then review your license details before repeating any step if your session was interrupted.
The service page does not publish a list of error messages, but the published requirements help you identify which item to review. Always start with the text of the message shown in your account, then compare it with the following possibilities:
If the message is unclear, note its text, the time of the attempt and the stage where you stopped, then contact the official support channels shown on the service page. Never share your password or verification code with anyone, and do not treat a failed attempt as a final rejection without confirmation from the competent authority.
The two documents are often confused because both are called a license. The driving license belongs to the driver, while the Istimara is the vehicle registration and relates to the car itself. Each therefore has its own Absher service and its own requirements, so do not apply the conditions of one to the other.
The medical examination and the remaining license validity are published requirements for driving license renewal and have nothing to do with the condition of your car. If what you need to renew is the vehicle document, follow the guide to vehicle registration renewal on Absher and why it may fail, which explains that service’s requirements and steps.
Likewise, vehicle insurance does not appear among the driving license renewal requirements on the service page. If you are reviewing your car insurance at the same time for other reasons, read about comprehensive versus third-party car insurance to choose a suitable policy.
Yes, according to the official service page: the service is electronic through Absher without the need to visit traffic offices, provided the regulatory requirements are completed. If your case cannot proceed, follow the service message and the competent authority’s guidance.
The prerequisites tab requires the remaining validity of the license to be less than 365 days. You can check your license validity electronically through the driving license information service listed among the related services.
Yes. The official page lists a medical examination through a certified medical center among both the prerequisites and the required documents. Complete the examination at a certified center before starting the service.
The service steps mention choosing the renewal period of 2 years, 5 years or 10 years while reviewing your details. Choose from the options shown to you and review what applies to each option as displayed in the service.
The steps include filling in your National Address details for license delivery and then paying the delivery fees by card. The National Portal also lists a digital driving license display service among the related services, which is separate from renewal.
Prepare the driving license renewal requirements first: pay the fees and any violations, complete the medical examination at a certified center, and confirm that the remaining validity meets the published condition. Then follow the steps on Absher and check for the success message. If the request cannot proceed, address the item identified in the message or request clarification through the official channels.
