older vehicle E20 compatibility

The Union government has ruled out offering pure petrol or lower ethanol blends alongside E20, saying multiple fuel grades would create major logistical, storage and distribution challenges across India’s retail network. Government Rejects Pure Petrol and E10 Option The Petroleum and Natural Gas Ministry said maintaining separate supplies of pure petrol, E10 and E20 would require additional storage tanks, transportation systems and dispensing infrastructure at fuel stations. According to the government, such parallel distribution would significantly increase operational costs and complicate fuel handling across refineries, depots and petrol pumps. The ministry also argued that reverting to lower ethanol blends could affect investments already made in ethanol production, procurement and fuel-distribution infrastructure. E20 Fuel Benefits Highlighted by Centre The government maintained that E20 offers a higher octane rating, improved anti-knock properties and cleaner combustion compared with lower ethanol blends. It also said ethanol blending helps reduce crude oil imports, save foreign exchange, support farmers and lower lifecycle carbon emissions. However, the government has acknowledged that E20 is currently costlier to produce than pure petrol at prevailing crude oil prices. It has also accepted that some vehicles may experience a fuel-efficiency reduction of approximately 3% to 5%. Older Vehicle Compatibility Concerns Continue Vehicle owners have raised concerns about using E20 in older cars and two-wheelers that were originally designed or certified for lower ethanol blends. The government and automobile manufacturers have maintained that E20 does not cause widespread engine damage, although certain older vehicles may require replacement of rubber components, seals or gaskets over time. The ministry said nationwide implementation followed testing and consultations with fuel companies, vehicle manufacturers and technical agencies. It reiterated that offering consumers multiple ethanol-blend choices would not be commercially or operationally feasible.
