About

A calculator, not an authority.

fuelxhub.com exists for one reason: E20 arrived at Indian pumps faster than clear, calm information did.

What this site does

It does three small things well. It tells you how cautious your vehicle should be with ethanol blends, based on type, age and OEM guidance. It calculates the exact litres to mix if you want a specific blend. And it estimates what ethanol does to your mileage and monthly fuel spend, in rupees.

What this site does not do

It does not certify fuel quality. It does not clear your vehicle for any blend. It does not replace your owner's manual, your OEM's written guidance, or a qualified mechanic who can actually see your fuel lines. Every number here is an estimate built on public information and simple arithmetic.

How the numbers work

The blend maths is straightforward proportion: to reach a target ethanol percentage from a known source fuel, we solve for the litres of each. The mileage estimate scales with ethanol's lower energy content per litre. Real-world results vary with engine tuning, traffic, tyre pressure, AC use and fuel quality — which is why we show estimates, never promises.

Where the information comes from

Our framing follows publicly available material from NITI Aayog and the Ministry of Petroleum & Natural Gas ethanol blending roadmap, plus mainstream reporting on Oil Ministry clarifications. All sources are linked on the home page.
