KPDN Probes Seven Selangor Stations Over Contaminated RON95

The Ministry of Domestic Trade and Cost of Living (KPDN) Selangor branch is conducting an official regulatory investigation into seven licensed petrol stations across Selangor following 10 formal consumer complaints alleging water-contaminated RON95 petrol. Supervised by KPDN Selangor Director Muhamad Hanif Asa'ari, this enforcement action addresses fuel adulteration causing vehicle breakdowns, engine stuttering, and burnt engine valves for Malaysian motorists. Authorized fuel retail outlets across Klang, Sungai Buloh, Puchong, and Shah Alam are subject to statutory sample testing by the Department of Chemistry Malaysia (Jabatan Kimia Malaysia) under the Trade Descriptions Act 2011 to determine whether retail fuel storage infrastructure compromised consumer supplies.

Key Facts

The regulatory and technical details gathered during the KPDN Selangor investigation into contaminated RON95 petrol encompass formal complaints, targeted locations, statutory inspection notices, and verified vehicle mechanical impacts.

KPDN Selangor seized 27 tins of RON95 petrol samples across seven licensed stations in Klang, Sungai Buloh, Puchong, and Shah Alam for chemical verification.

What Engine Damage Does Water-Contaminated Petrol Cause?

Water contamination in automotive fuel systems causes abnormal engine noise, vehicle jerking or stuttering, sudden power loss, complete engine startup failure, and severe internal damage such as burnt engine valves. Official vehicle manufacturer service centres verified that engine failures reported by complainants stemmed directly from liquid water present inside the vehicles' fuel tanks.

According to the statement released on Saturday, 17 October 2026, by KPDN Selangor Director Muhamad Hanif Asa'ari, inspections conducted by automotive service centres corroborated user claims regarding fuel-line contamination:

"Investigations revealed that user complaints involved various engine failure symptoms such as abnormal engine noises, jerking, loss of power, engine failure to start, as well as cases of burnt engine valves."

Laboratory test results from the Department of Chemistry Malaysia remain pending to confirm whether the contamination originated within the commercial underground storage tanks of the petrol stations or elsewhere along the distribution chain.

Official vehicle manufacturer service centre inspections confirmed that mechanical failures and burnt engine valves among complainants were caused by water contamination in vehicle fuel tanks.

Which Legal Provisions Apply to Contaminated Fuel Sales in Malaysia?

Petrol retailers supplying adulterated or water-contaminated fuel in Malaysia face regulatory scrutiny under Section 32, Section 5(1)(c), Section 6(1)(d), and Section 7 of the Trade Descriptions Act 2011. Even when retail stations hold valid operating licences, regulatory bodies issue statutory notices to obtain records and penalise false trade descriptions regarding fuel composition.

During surprise inspections conducted on Friday across Klang, Sungai Buloh, Puchong, and Shah Alam, KPDN enforcement officers served notices under Section 32 of the Trade Descriptions Act 2011 to demand relevant documentation and supply data. Additional investigative proceedings evaluate potential offences under Section 5(1)(c), read alongside Section 6(1)(d) and Section 7 of the Act, which prohibit false trade descriptions relating to the true content and standard of supplied goods.

Underground storage tank maintenance remains a mandatory operational standard for all oil companies and retail station operators to prevent moisture penetration and groundwater seepage.

Notices under Section 32 of the Trade Descriptions Act 2011 were issued to all seven licensed stations to probe potential breaches regarding false trade descriptions under Section 5(1)(c).

How It Compares for Malaysian Users

For Malaysian motorists driving passenger cars in high-density urban areas such as Selangor and the Klang Valley, fuel contamination poses severe mechanical and financial risks. Commuters operating in heavy urban traffic suffer immediate stalling, leaving vehicles immobile in transit corridors across Klang, Puchong, and Shah Alam.

KPDN Selangor explicitly directed affected motorists to retain two mandatory pieces of evidence to substantiate consumer tribunal claims and aid ongoing enforcement investigations: official petrol purchase receipts and formal vehicle inspection reports from authorised service workshops. Furthermore, oil companies and petrol station operators bear continuous statutory responsibility to service and maintain subterranean fuel storage tanks against water infiltration.

Affected Malaysian motorists must preserve original petrol purchase receipts and manufacturer workshop inspection reports to support official regulatory compensation claims.

Common Questions

What should affected Malaysian drivers do if they suspect fuel contamination?

Motorists must immediately retain their petrol purchase receipts and obtain a formal diagnostic inspection report from an authorised vehicle service centre. These documents serve as compulsory evidentiary proof required by KPDN Selangor to facilitate statutory investigations and pursue compensatory restitution.

Which petrol stations in Selangor are under investigation for water contamination?

KPDN Selangor inspected seven licensed petrol stations situated in Klang, Sungai Buloh, Puchong, and Shah Alam. Enforcement officers seized 27 sample tins of RON95 petrol from the affected dispensers for laboratory evaluation by the Department of Chemistry Malaysia.

What legal penalties do petrol stations face for selling contaminated RON95 petrol?

Retailers face investigation under Section 5(1)(c), Section 6(1)(d), and Section 7 of the Trade Descriptions Act 2011 concerning false trade descriptions. Premises are compelled via Section 32 statutory notices to furnish supply manifests, maintenance logs, and commercial documentation.
