Karnataka Reports Ethanol Above E20 Limit in Petrol, Seeks Centre's Explanation

The dispute centres on whether petrol sold as E20 in Karnataka contained more ethanol than its stated 20% limit. Karnataka's Consumer Affairs Minister Rizwan Arshad said department tests found ethanol levels reaching 31.2%, NDTV India reported.

The department collected 63 petrol samples, according to the same report. The highest reported reading was 11.2 percentage points above the stated limit.

The findings became public on November 6, 2026. Announcing the test results in Bengaluru, Arshad said the samples had been collected from across Karnataka, according to NDTV India.

Business Line described the samples behind the allegations as coming from Bengaluru and nearby districts. The accounts therefore differ in how broadly they describe the sampling area. The supplied reports do not provide a location breakdown for all 63 samples.

The state alleged that oil companies had sold petrol containing ethanol above the 20% limit and sought action, Business Line reported. The maximum reading reported was 31.2%, not a figure established for every sample.

Karnataka also sought an explanation from the Union government, according to India: United We Stand. Alongside that demand, Arshad called for a consumer relief fund, NDTV India reported, while India Today described the state's demand as seeking consumer compensation.

The current position is a state government allegation backed by its announced petrol test results. The supplied coverage does not include a response from the Union government or the oil companies, or establish that compensation has been approved.

The reported maximum raises a specific fuel standards question: why a sample of petrol sold as E20 contained 31.2% ethanol. The available reports do not establish how many of the 63 samples reached that level or how widely those results apply beyond the tested locations.

The immediate questions are how the Union government and oil companies respond, and whether Karnataka's demand produces action or consumer relief. A sample-by-sample breakdown would also clarify the extent of the reported excess and resolve the differing descriptions of where testing took place.
