E20 petrol rolls out April 1: Is your vehicle ready? Compatibility, mileage & price explained

From April 1, all petrol pumps across India will sell E20 ethanol-blended petrol. This move promises cleaner fuel and reduced oil imports, but there’s another side to this. Some experts warn that older vehicles may face engine issues and lower mileage. Flex-fuel vehicles (FFVs) are automobiles with an internal combustion engine designed to run on a mix of petrol & ethanol.These vehicles are being promoted, but affordability, GST rates, and infrastructure remain challenges. The government credits farmers for helping cut crude imports by 4.5 crore barrels annually. Will E20 fuel benefit consumers or raise costs?
