India Defends E20 Petrol Rollout Amid Engine Damage Claims

The Government of India and industry experts are defending the nationwide rollout of E20 petrol, a 20 percent ethanol blend that became mandatory for all oil companies on April 1, 2026. Union Minister Hardeep Singh Puri and energy veterans R. Ramachandran and Raj Kumar Dubey dismissed social media claims of engine failure as unsubstantiated, though Puri acknowledged a potential marginal drop in fuel efficiency. They argued the program is scientifically validated and will save the government between 1.8 lakh crore and 1.9 lakh crore rupees in foreign exchange.

Opposing the policy, Aam Aadmi Party national convenor Arvind Kejriwal accused the government of using the country as an experiment lab. He alleged that E20 fuel causes vehicles to break down, damages engine parts, and reduces mileage, particularly for vehicles manufactured before March 2023. Kejriwal announced plans to write to Prime Minister Narendra Modi to request a rollback of the program, citing a June 30 Supreme Court submission where the government allegedly described the rollout as an experiment.

Automotive representatives from Maruti Suzuki India Limited and Toyota Kirloskar Motor countered these claims, stating that rigorous testing on both new and older models showed no evidence of excessive wear or corrosion. Former Engineers India Ltd head Vartika Shukla emphasized that the target for 20 percent blending was achieved in December 2025, five years ahead of schedule. Meanwhile, the Government of Bhutan rejected an offer from Indian oil companies to supply E20 petrol, citing concerns over fuel stability and storage in its high-moisture mountainous terrain.
