E20 definition
What is E20 petrol?
Reviewed · Next source review due
Short answer
E20 is petrol blended with 20% ethanol by volume. The name describes the petrol at the pump, not your car. Your car's own E20 answer is one tap away.
Published Government position
What the published record says
The 2022 biofuels policy provides for ethanol-blended petrol with ethanol up to 20%, while the NITI Aayog roadmap defines E20 as the 20% blend used for the national transition.
Why this is the answer
Ethanol is blended into petrol before the fuel reaches the retail outlet. E20 identifies the blend level, not a separate fuel brand.
Your car's answer depends on its model year, engine and transmission, and the maker's own document gives it.
Important limits
- The E20 label at the pump describes the petrol, not your car. Your car's own answer comes from its maker's document.
- The petrol sold at the pump must still meet the national fuel standard.
