If you own a Tata Tiago, Punch, Nexon, Altroz or any other Tata petrol vehicle, you may be wondering whether your car supports E20 fuel.
This guide covers every Tata petrol vehicle currently available in India, along with manufacturing year, variants, engine details and simple methods to verify E20 compatibility.
What is E20 Petrol?
E20 petrol is a blend containing:

The Government of India introduced E20 fuel to reduce crude oil imports, lower emissions and encourage the use of renewable fuels. Modern Tata petrol engines are engineered to operate with E20 fuel where specified by the manufacturer.
