Govt. Clarifies on E20 Fuel: No Engine Damage, Minor Mileage Dip
The Indian government is responding to concerns about E20 fuel, which is gasoline mixed with ethanol.
They're saying it won't damage your engine.
Studies show it performs similarly to regular gas.
Cars made since April 2023 are already built to use it.
Older cars might use a little more gas, but it’s not a big difference.
E20 is good for the environment because it reduces pollution.
Plus, it supports the economy and farmers.
Government clarifies on E20 petrol following reports of engine damage and performance impacts.
Studies confirm no significant difference in power, torque, or fuel consumption with E20.
E20-compliant vehicles with upgraded components have been available since April 2023.
Older vehicles might see a 1-2% (E10-compatible) or 3-6% (others) fuel efficiency drop.
Ethanol blending reduces CO2 emissions and enhances India’s energy security and supports farmers.
