Delhi Chief Minister Arvind Kejriwal has written to 29 automobile manufacturers to seek written clarification on the impact of E20 ethanol-blended fuel on vehicle mileage and engine safety.

During a press conference, he highlighted discrepancies between government statements about E20 fuel safety for older vehicles and the companies' own owner's manuals, which prohibit using petrol with more than 10% ethanol in vehicles manufactured before 2023.Kejriwal alleged these conflicting positions constitute a major issue, demanding public written clarification from the automakers.He also requested compensation assurances for consumers if E20 fuel reduces mileage or causes vehicle damage.

The AAP leader plans to write to Prime Minister Narendra Modi, urging the government to make E20 fuel optional and allow consumers to choose between different fuel grades.The controversy stems from claims that E20 fuel may slightly reduce mileage but not damage vehicles, contradicting manufacturer guidelines.
