About KnowYourFuel.in

Right Fuel. Better Mileage. Greener Tomorrow.

KnowYourFuel.in exists to cut through the noise around India's switch to E20 petrol. When E20 became India's standard petrol in 2025, millions of drivers were left with the same questions: Is my vehicle built for this? Will my mileage drop? Is my warranty safe? The answers were buried in policy documents, contradictory headlines and viral misinformation.

We turn that confusion into clear, specific answers. Our two free tools - the E20 Compatibility Checker and the Mileage & Cost Calculator - give you a verdict for your vehicle and the real rupee impact, backed by plain-English guides.

What we stand for

• Honesty over hype. We separate verified facts from myths (no "ants in fuel" scares).
• Sources, always. We cite ARAI, the Ministry of Petroleum & Natural Gas, SIAM, OEMs and independent surveys.
• People first. Every tool is free, fast, mobile-friendly and needs no sign-up.
• No politics. We're here to help you make decisions, not to take sides.

How we create our content

Our guides are researched from publicly available government data, testing agency reports, industry statements and reputable news reporting, and are produced with AI assistance and human editorial review. Where figures are estimates or self-reported, we say so. See our editorial guidelines for details.
