The record
Written from the 11 reports below. Nothing here is unsourced.
- The Indian government stated in Parliament that there is no current plan to increase ethanol blending in petrol beyond 20%, and that E20 fuel is safe for use, with no evidence of widespread engine damage.
- Minister Nitin Gadkari and the Ministry of Petroleum acknowledged that E20 may reduce vehicle mileage by 2-6%, particularly in older vehicles, but emphasized the fuel's benefits for emissions reduction, energy security, and price stability.
- The government admitted, however, that no formal assessment has been conducted to determine the share of vehicles on Indian roads that are fully compatible with E20 petrol.
- This has left auto manufacturers and consumers facing uncertainty about long-term engine durability and fuel economy.
- While the policy aims to reduce import dependence and support farmers, the lack of a compatibility study raises questions about potential hidden costs for vehicle owners.
- Watch for whether the government commissions a formal compatibility study or issues updated guidelines for older vehicles.
What to watch next
- Watch for a formal vehicle compatibility assessment.
- Monitor consumer complaints on mileage or engine issues.
- Track auto manufacturer responses or recalls related to E20.
