RON95 Contamination: Perak Records 25 Complaints as Drivers Raise Concerns
RON95 Contamination: Perak Records 25 Complaints as Drivers Raise Concerns
Perak's Domestic Trade and Cost of Living Ministry (KPDN) received 25 complaints over suspected RON95 petrol contamination in October 2026, with water in fuel storage tanks suspected as a possible cause. The complaints have prompted investigations, with motorists advised to preserve evidence if their vehicles are affected.
The complaints came from five districts across Perak, while fuel samples have been sent to the Department of Chemistry Malaysia for further analysis. However, laboratory results are still pending, meaning the suspected contamination has not yet been officially confirmed.
For Malaysian drivers, the situation raises an important question: what should you do if you suspect the petrol you purchased has damaged your car?

What happened with the suspected RON95 contamination in Perak?
25 complaints were received in October. KPDN Perak director Datuk Kamalludin Ismail confirmed that the complaints involved suspected contamination of RON95 petrol, believed to be potentially linked to water entering fuel storage tanks.
The complaints were received from five districts across Perak, namely Kinta, Kuala Kangsar, Taiping, Parit Buntar and Manjung. Following the reports, enforcement officers conducted inspections and monitoring at the locations involved.
Fuel samples have been collected for investigation. KPDN sent the samples to the Department of Chemistry Malaysia for laboratory analysis to determine whether contamination had occurred.
As of 1 November 2026, the department had not received the laboratory results. KPDN will decide on further action after reviewing the findings.
What motorists need to know about the complaints
The complaints currently involve RON95 only. According to KPDN Perak, none of the complaints received so far involved diesel or RON97 petrol.
However, the situation is not limited to Perak. During October, motorists in Penang, Kedah and Selangor also raised allegations that suspected water contamination in petrol had caused problems with their vehicles.
Some of these incidents gained attention on social media, prompting investigations and the collection of fuel samples by enforcement authorities.
Motorists should distinguish between allegations and confirmed findings. Although several drivers have reported vehicle problems, the exact cause of the incidents and whether the fuel was contaminated must be established through proper investigations.

What to do if you suspect contaminated petrol
Drivers who suspect fuel-related vehicle damage should prioritise safety and preserve evidence. A vehicle problem occurring after refuelling does not automatically prove petrol contamination, so proper documentation and inspection are important.
1. Stop driving if your vehicle shows serious problems
If your car suddenly loses power, struggles to start, stalls repeatedly or develops unusual engine behaviour after refuelling, avoid continuing to drive it.
Find a safe place to stop and arrange professional inspection if necessary. Continuing to operate a vehicle with serious engine or fuel-system problems could potentially cause further damage.
Ask a qualified mechanic to inspect the vehicle and document any findings, particularly if the suspected issue involves the fuel system.
2. Keep your petrol receipts and supporting evidence
Proof of purchase is important when investigating a suspected fuel-related incident. Keep your petrol receipts, including the date, time, station location and amount of fuel purchased.
Other useful supporting documents include vehicle inspection reports, repair invoices, photographs and records of any communication with the petrol station or relevant authorities.
These documents may help establish a timeline between the refuelling incident and the vehicle problems you experienced.
3. Report the incident and understand your claim options
Motorists who suspect they have suffered losses should make a formal complaint to KPDN and contact the relevant petrol station or fuel company to report the incident.
According to KPDN Perak director Datuk Kamalludin Ismail, affected consumers should retain relevant documents and evidence to support claims through the Tribunal for Consumer Claims Malaysia (TTPM) or civil courts.
Keep in mind that submitting a complaint does not automatically guarantee compensation. Any claim will depend on the available evidence, applicable requirements and the findings of the relevant proceedings.
Can water-contaminated petrol damage your car?
Water entering a vehicle's fuel system can interfere with normal engine operation. Petrol engines are designed to operate using the correct fuel, and water contamination can disrupt the combustion process.
Depending on the amount of water present and the vehicle's fuel-system design, possible symptoms may include difficulty starting, engine misfires, rough idling, reduced power or unexpected stalling.
However, these symptoms are not exclusive to contaminated petrol. Problems involving spark plugs, fuel pumps, injectors and other engine components can produce similar symptoms.
A professional inspection is therefore necessary. Drivers should not assume that every engine problem occurring after refuelling is caused by contaminated petrol.
Expert tip: Keep every refuelling receipt.
Make it a habit to retain petrol receipts, particularly when your vehicle develops unusual problems shortly after refuelling. Recording the date, time and petrol station can help establish a timeline when reporting a suspected fuel-quality issue.
Common mistake: Throwing away your petrol receipt.
Without proof of purchase, it may become more difficult to establish where and when you refuelled. Do not rely solely on social media posts or verbal complaints when preparing a potential claim.
Keeping track of your car ownership information
Keeping your vehicle information organised can make car ownership easier to manage. When unexpected vehicle problems occur, having your ownership information and relevant records readily accessible can help you stay organised.
The Motorist App is a car ownership platform that supports motorists with their vehicle-related needs. However, it is not a KPDN reporting channel, fuel-testing service or compensation claims platform.
Here is a simple comparison between managing your vehicle information manually and using the Motorist App as part of your car ownership routine.
| Comparison | Traditional approach | Motorist App |
|---|---|---|
| Vehicle ownership support | Manage information through separate records and documents. | Access Motorist's car ownership platform. |
| Fuel purchase evidence | Keep physical receipts and personal records. | Retain original receipts and supporting evidence separately. |
| Fuel contamination investigation | Contact the relevant authorities directly. | Not an official investigation or reporting channel. |
| Compensation claims | Follow the applicable official claim process. | Claims must be submitted through the appropriate channels. |
The important thing is to stay organised and keep supporting documents whenever your vehicle experiences unexpected problems. Motorist helps make car ownership more convenient, while official investigations and consumer claims remain the responsibility of the relevant authorities and institutions.
What Malaysian drivers should remember
The 25 complaints received by KPDN Perak highlight growing concerns over suspected RON95 petrol contamination, but the cause has yet to be officially confirmed. Until laboratory results are available, motorists should avoid speculation, keep their refuelling records and report suspected problems through the proper channels.
