India rolled out 20% ethanol-based petrol in July 2025, five years ahead of its 2030 target.
India began blending 1.5% ethanol with petrol in 2014, increased it to 10% in 2022, and to 20% in July 2025. It is now available across 1,900 retail outlets.
Ethanol emits 65% less CO2 than petrol and has a higher octane rating (around 108.5). It helps burn petrol better and reduces carbon emissions. Being domestically produced, it reduced India’s oil import dependence and saved ₹1.44 lakh crore in foreign exchange since 2014.
Reduced mileage, rust-related damage, and clogged filters are a few issues Indians are reporting due to consistent ethanol usage.
Ethanol absorbs moisture, thus accelerating corrosion. Its low energy content causes efficiency reduction.
New cars manufactured after 2024 are compliant with E20, but the older versions are not. Non-compatible engines may face corrosion and lubrication issues.
As per the government, E20 usage will not void insurance. However, the warranty may be compromised due to fuel compatibility issues.
