M&M Says Its Vehicles 'Safe' To Drive With E20 On E10

Mahindra & Mahindra Ltd announced on Thursday that it would honour all warranty commitments for its vehicles in cases related to E20 fuel usage.

According to a company statement, "Will honour all warranty commitments to customers on account of E20 fuel usage. Mahindra engines are fully compliant with existing gasoline standards, and all our vehicles can be operated safely with E20 fuel."

"Vehicles produced post April 1, 2025, are specially calibrated for E20 fuel to ensure acceleration and fuel efficiency. Earlier produced vehicles, whilst being completely safe to drive, could see a minor variation in either acceleration or fuel efficiency depending on driving behaviour," M&M said.

Earlier in the day, M&M CEO, Automotive Division, Nalinikanth Gollagunta told reporters in Mumbai on the sidelines of the annual convention of Society of Indian Automobile Manufacturers that all its vehicles are safe to drive on E20 fuel.

"All our vehicles are safe to drive with E20 on E10. So, you don't have to worry about the vehicle per se, or the warranty, or any of those challenges from driving the vehicle," he said about the advisory to customers.

"On April 1, 2023, the company first calibrated vehicles for E10 and on April 1, 2025, for E20. Anything produced after April 1, 2025, is calibrated for E20," he added.

Citing government regulations, he said in older vehicles which are already on the roads, calibration is not allowed. When asked what the impact of E20 fuel on the older vehicles will be, he said, there will definitely be a performance hit to that extent because it's not calibrated.

"You will see either an acceleration degradation, or you could see a fuel efficiency degradation," Gollagunta said.
