Automakers in India have now started designing engines that are E20-compatible, especially models manufactured from 2023 onwards
What you’re getting as “normal petrol” is now typically 20% ethanol-blended petrol.
If you’re filling your tank with what’s labelled as normal petrol, chances are you’re now getting a fuel blend that’s very different from what was sold a few years ago. While most motorists assume regular petrol is pure gasoline, it’s actually a mixture, now increasingly dominated by ethanol.
What’s in your tank now?
Until recently, normal petrol (technically called E0 or 91 RON petrol) contained 10% ethanol. But in a major policy shift, most pumps now dispense E20 (petrol blended with 20% ethanol) as the default normal fuel option. This transition has already begun at many outlets and is gradually expanding nationwide.
So yes, what you’re getting as “normal petrol” is now typically 20% ethanol-blended petrol.
Can your engine handle 20% ethanol?
That depends on how new your vehicle is. Automakers in India have started designing engines that are E20-compatible, especially models manufactured from 2023 onwards. These vehicles can run on E20 without issue.
But if your vehicle was made before that, particularly before 2015, it might not handle the new blend optimally. Engine parts not designed for higher ethanol content may suffer minor degradation or performance issues over time.
What does the government say?
According to the Ministry of Petroleum and Natural Gas and the Automotive Research Association of India (ARAI), “E20 fuel passed all major engine tests and showed no significant adverse effects.” These included mechanical performance checks and 1 lakh-kilometre endurance tests on both carburetted and fuel-injected engines.
Hot and cold startability tests also showed E20 to be safe, though the government does concede that mileage may dip by 1-2% in E10-designed engines calibrated for E20. In older vehicles, that drop could range between 3-6%. However, the ministry maintains that this can be resolved through better engine tuning and use of ethanol-compatible parts.
Why is this shift happening?
The ethanol blending program is part of India’s broader push to:
- Reduce dependence on crude oil imports
- Cut carbon emissions
- Boost farmer incomes by sourcing ethanol from sugarcane and grain
The government had initially set 2025-26 as the target for 20% ethanol blending, but implementation has been fast-tracked. A roadmap is also in place to push the blend further to 27% in coming years.
Is there a way to avoid ethanol-blended petrol?
Yes, though it’s not cheap. If you want lower or no ethanol in your fuel, look for premium variants like Speed 97 or XP100. These fuels usually have minimal ethanol content (as low as 5-10%) and sometimes none at all.
However, XP100, marketed as “India’s purest premium petrol” can cost between Rs 150 and Rs 170 per litre and is available only at select stations in big cities.
What is ethanol and where does it come from?
Ethanol is an alcohol-based biofuel derived mainly from sugarcane, maize, or grains. It is not drinkable, as denaturants are added to fuel-grade ethanol. India has over 800 ethanol-producing plants, and the fuel-grade version (99.5% pure) is delivered to oil companies like Indian Oil, Bharat Petroleum, and Hindustan Petroleum. Ethanol is blended into petrol at refineries or terminals, not at the petrol pump.
How does India compare globally?
India is not alone in this approach. Ethanol blending is a global trend:
- Brazil mixes 27% ethanol in standard petrol and has vehicles that run entirely on ethanol.
- The US started ethanol blending in the 1990s and now uses E10 as standard. In some cases, E15 and
- E85 are also used, especially in Flex-Fuel vehicles.
- Europe varies: France uses E10, Germany E5, and Sweden blends up to 85% ethanol.
- China made E10 mandatory in 2017.
- Thailand offers E10, E20, and E85 options to consumers.
These moves aim to reduce carbon footprints, support local agriculture, and stabilise fuel pricing.
What should vehicle owners do now?
Check your vehicle manual or contact the manufacturer to confirm if your vehicle is E20-compatible. If you’re driving a model launched in or after 2023, you’re likely in the clear. If not, watch out for slight mileage drops and performance variation. For older vehicles, especially pre-2015 ones, avoid E20 if you’re concerned about wear and tear, premium fuels may be the better choice.
