Analysis of 27 fuel samples collected from seven petrol stations across Selangor following complaints of possible water contamination could take several months to complete.
Selangor Domestic Trade and Cost of Living Ministry (KPDN) director Muhamad Hanif Asa’ari said the RON95 petrol samples were collected from stations in Klang, Sungai Buloh, Puchong and Shah Alam.
“At this stage, KPDN cannot conclude that the fuel was contaminated with water until the sample analysis results are obtained and further investigations are completed.
“It is acknowledged that the process could take several months. However, KPDN has requested the Department of Chemistry Malaysia to expedite the analysis so that further action can be taken,” he told reporters on Sunday.
KPDN Selangor had earlier inspected the seven petrol stations and collected the 27 samples following complaints from motorists who claimed that contaminated fuel had damaged their vehicle engines.
The enforcement operation and field investigations were carried out on Saturday following public complaints and reports circulating on social media.
Muhamad Hanif said KPDN had so far received 10 formal complaints involving the seven petrol stations.
He said the reported problems included unusual engine noises, engine sputtering, power loss and vehicles failing to start. In some cases, engine valves were reportedly burnt.
“Further inspections by vehicle manufacturers’ service centres also confirmed that water contamination in the fuel tanks had caused engine damage in some complainants’ vehicles,” he said.
He added that all the petrol stations involved held valid Special Approval Licences (CSA) and licences issued under the Petroleum Development Act 1974 (PDA).
KPDN has issued notices under Section 32 of the Trade Descriptions Act 2011, requiring the operators to submit business-related information and documents to assist the investigation.
The probe is being conducted into possible offences under Section 5(1)(c), read together with Sections 6(1)(d) and 7 of the same Act, concerning alleged false trade descriptions relating to the composition of the petrol supplied.
Meanwhile, Caltex Malaysia said it was aware of the developments surrounding the RON95 fuel quality concerns and would continue working closely with the authorities as investigations proceeded.
The company said samples had been collected from various stages of handling throughout the supply chain as part of its standard protocols and compliance measures.
“Samples have also been collected from the affected vehicles reported to us, and all samples have been sent to accredited laboratories for examination.
“We appreciate our customers’ patience throughout this process.
“We remain committed to doing everything we can to resolve this matter, which we are treating with the utmost seriousness,” the company said.
