E20 Fuel Safe For Vehicles, Says Centre; No Compensation Fund Planned Replies Nitin Gadkari
Government-backed studies show no major performance issues in cars using 20% ethanol-blended petrol.
The central government has clarified that vehicles running on 20% ethanol-blended petrol (E20) have not shown any significant performance variations or component-related damage during testing. The assurance came after questions were raised in Parliament about engine issues, mileage loss, warranty disputes and insurance rejections linked to E20.
The response referred to detailed evaluations carried out by national automotive bodies. According to the findings, vehicles tested on E20 “have not shown any significant variations in performance” and “no adverse impact on components is observed.” The studies covered areas such as drivability, cold starts, material compatibility and overall engine behaviour.
On the issue of mileage loss, one of the most common public concerns, the reply noted that fuel efficiency depends on many factors beyond fuel composition. While replying to the question, union minister Nitin Gadkari said Greenhouse Gas (GHG) emissions in the case of Ethanol is less than that of petrol. Driving habits, regular servicing, tyre pressure, wheel alignment and air-conditioning usage all influence overall mileage.
The government also highlighted the environmental and performance advantages of ethanol. Ethanol’s higher octane rating helps engines resist knocking, and E20 functions at an effective RON 95. It also emits fewer greenhouse gases than petrol, supporting cleaner mobility goals.
A key part of the clarification centered on the design of older vehicles. Cars sold before April 1, 2023, were originally designed for E10, while those sold after that date are built with E20-compatible materials. Although older vehicles can still use E20, they were not engineered specifically for higher ethanol content.
Questions were also raised about whether 80% of vehicles sold between 2011 and 2025 are only compliant with lower ethanol blends, and if a breakdown of complaints across manufacturers and insurers would be released. The government confirmed that no proposal is currently under consideration to create a compensation fund for proven E20-related damage.
The clarification aims to address concerns from vehicle owners as India moves toward higher ethanol blending targets under its national clean fuel strategy.
