The E20 sticker and your manual.
Two-wheelers made since April 2023 carry an E20 sticker on the tank or the fuel lid. This tells you the fuel is approved.
For older bikes and scooters: open the fuel section of your owner's manual. It names the approved blend. Most run E20 today.
Mileage and maintenance
What E20 does to mileage.
ARAI puts the E20 effect at 2 to 6 percent lower mileage. Tyre pressure, routine service and road conditions matter much more. A timely service is more important than any fuel choice.
