E20 Fuel Efficiency Drop 2-6%, No Engine Failures: Gadkari in Lok Sabha
UPSC / SSC current affairs note · IR
Why in news
Union Minister Nitin Gadkari informed Lok Sabha about E20 ethanol-blended petrol tests. The tests by ARAI, SIAM, and Indian Oil found a 2-6% fuel efficiency decline but no engine failures. This is crucial as India pushes E20 adoption to cut emissions and oil imports.
Background
India aims to achieve 20% ethanol blending in petrol by 2025-26, advancing from the earlier target of 2030. E20 is a blend of 20% ethanol with petrol. Concerns about vehicle compatibility and efficiency have been raised, prompting these tests.
Key facts
E20 reduces fuel efficiency by 2-6% across vehicle categories and ages.
Tests by ARAI, SIAM, and Indian Oil found no engine failures attributable to E20.
The efficiency decline was observed in both old and new vehicles.
The tests covered various vehicle categories, including two-wheelers, four-wheelers, and commercial vehicles.
The findings were presented by Nitin Gadkari in a written reply to Lok Sabha.
E20 is part of India's ethanol blending program to reduce crude oil imports and emissions.
The 2-6% efficiency drop means slightly lower mileage for consumers.
Despite efficiency loss, no long-term damage to engines was reported.
