Frequently Asked Questions

Quick answers to the most common queries about E20 petrol in India.

What is E20 petrol?
E20 petrol is a blend of 20% ethanol and 80% fossil-fuel gasoline. The Indian government has mandated its phased nationwide rollout to lower crude oil import dependencies and cut tailpipe emissions.
Will E20 petrol damage my BS4 or older vehicle?
Yes, if used long-term in an incompatible engine. Most BS4 and older Indian vehicles are designed to handle up to 10% ethanol (E10). Sustained usage of E20 fuel can accelerate corrosion in metal fuel tanks, degrade older rubber hoses, and cause carburetors to run lean, leading to misfires.
How can I find ethanol-free E0 petrol in India?
True E0 petrol is no longer sold as a standard regular fuel grade. However, premium super-high-octane fuels, specifically IndianOil XP100, Bharat Petroleum Speed 100, and Hindustan Petroleum poWer100, are formulated as pure, ethanol-free gasoline. You can use our finder tool to locate pumps offering these fuels.
Does E20 petrol lower fuel mileage?
Yes. Ethanol contains roughly 33% less energy density than pure fossil gasoline. In real-world driving conditions, running E20 petrol results in a minor mileage drop of approximately 1.5% to 3% compared to standard E10 or E0 fuels.
