E20 Ethanol Blend Cuts Fuel Economy by 2-6%
India is mixing 20% ethanol into petrol, called E20.
This mix can make cars use 2 to 6 percent more fuel, so you might get fewer miles per litre.
Tests show the engines still work fine and there are no big problems.
The government says the fuel is better for the environment and helps keep prices lower.
Some people worry that older cars might get damaged, but so far no major engine failures have been found.
Petrol blended with 20% ethanol (E20) can reduce fuel economy by 2–6% depending on vehicle type and age.
Engine durability and on‑road tests have shown no failures linked to E20.
More than 20 crore two‑wheelers and 3 crore petrol cars are already using E20 without widespread engine damage.
E20 improves acceleration, ride quality and cuts carbon emissions by about 30% versus E10.
Critics argue older vehicles not designed for 20% blends may suffer, and some consumers report reduced mileage.
