Armizan: Preliminary tests on 43 RON95 samples find no significant water contamination

KUALA LUMPUR, Nov 5 — Preliminary laboratory tests on 43 petrol samples have shown no significant water contamination, according to Dewan Rakyat today. Domestic Trade and Cost of Living Minister Datuk Armizan Mohd Ali announced that the tests detected water content below the minimum detectable level for all 43 samples analyzed. This finding was reported earlier in the day by the Department of Chemistry on October 29, 2026.

Armizan stated that all 43 samples recorded a water content of less than 0.05 percent, which is well below the minimum threshold for reporting water contamination. The tests were conducted following viral allegations that some petrol stations in Selangor and northern states were selling contaminated RON95, which could potentially damage cars' engines.

These allegations began circulating on social media last month and gained further attention through media reports. Armizan emphasized that the remaining samples are still undergoing thorough laboratory testing, and a comprehensive report will be released once the Department of Chemistry finishes its analysis. The first formal complaint was received by the ministry on October 3, leading to targeted inspections in Selangor and Perak.

By October 31, inspections had been carried out at eight petrol station brands across eight states, in addition to three oil company depots. Armizan informed Parliament that a total of 262 RON95 samples were collected, with 259 samples obtained from petrol stations and three from oil company depots.
