New Delhi: Karnataka Food, Civil Supplies and Consumer Affairs Minister Rizwan Arshad has intensified the dispute over E20 petrol, questioning the testing methods adopted by oil marketing companies and demanding that the Centre provide fuel at a discounted price.
Arshad maintained that the Karnataka government stands by its findings alleging that petrol samples contained more than the prescribed 20 per cent ethanol. He said the state would continue to challenge the Centre over excessive blending and conduct random inspections to ensure compliance with fuel standards.
Speaking about the controversy, the minister claimed that Karnataka had tested samples at a laboratory accredited by the National Accreditation Board for Testing and Calibration Laboratories (NABL). He questioned the credibility of testing allegedly conducted by oil company officials using water-based hydrometers purchased online.
Arshad demanded that an independent third party conduct fuel testing through a transparent process, arguing that the state government had little confidence in the methods adopted by oil marketing companies.
Karnataka Claims 63 Samples Tested
The minister said Karnataka had collected 63 fuel samples from oil marketing companies beginning September 21, 2026, and sent them for laboratory examination.
He maintained that the samples were tested using gas chromatography and that the collection records carried signatures from department officials, marketing representatives and petrol pump dealers.
Arshad also questioned the argument that excessive ethanol blending could have occurred at individual retail outlets. He pointed out that Karnataka has six ethanol blending terminals and argued that the blending process is centrally regulated.
Minister Raises Concerns Over Vehicle Performance
Arshad referred to concerns allegedly raised by the Society of Indian Automobile Manufacturers in a letter to the Union Petroleum Ministry dated July 28, 2026, regarding the possible impact of E20 fuel on vehicle engines.
He also questioned reports surrounding insurance coverage for potential E20-related vehicle damage and cited concerns about the compatibility of higher ethanol blends with conventional engines.
The minister argued that E20 petrol affects vehicle mileage and engine performance, demanding that consumers receive the fuel at a reduced price to compensate for its impact.
Questions Over Possible E30 Rollout
Arshad further questioned statements suggesting that a decision had already been taken regarding E30 petrol, which contains 30 per cent ethanol.
He asked whether motorists had effectively been exposed to higher ethanol blends before any formal announcement or public consultation.
The minister also criticised Union Petroleum Minister Hardeep Singh Puri for not adequately addressing the concerns raised by Karnataka.
Reiterating the state’s position, Arshad said the government would continue demanding accountability, independent testing and protection for consumers amid the growing controversy over ethanol blending.
