SHAH ALAM — The Selangor state government has opened inquiries into seven petrol stations after receiving complaints from drivers who allege that substandard RON95 fuel has caused engine problems in their vehicles.

Motor vehicle owners reported experiencing mechanical failures they attributed to watery or contaminated petrol purchased from the stations under investigation. The complaints prompted state authorities to take action and examine the fuel quality and storage practices at the affected outlets.

Investigators are examining whether the petrol stations maintained proper storage standards and fuel handling procedures. The inquiry will determine whether contamination occurred at the retail outlets or if the fuel was already compromised when delivered to the stations.

The development underscores ongoing concerns about fuel quality standards across Malaysia's retail petrol network. Consumers are advised to keep receipts and documentation of any engine damage they believe resulted from contaminated fuel, as such records may be necessary for warranty claims or compensation proceedings.

Authorities have not yet announced a timeline for completing the investigation or disclosed the identities of the seven petrol stations involved.
