Overview

• Official tests by ARAI and ministry labs place E20 mileage loss at 1–6% and detect only minor material degradation in plastics and elastomers under controlled conditions.
• Many vehicle owners and service centres report efficiency drops of up to 20% and gasket failures in non-compliant pre-2023 models, prompting ECU tuning and component replacements.
• The Oil Ministry has dismissed claims that E20 use voids insurance as “totally baseless,” though some manufacturers warn that older cars may need modifications to maintain warranties.
• Consumer portal Theracemonkey publicly rejected a government-backed influencer collaboration as “propaganda,” even as other social-media personalities accept paid campaigns to promote ethanol blends.
• Almost all retail petrol stations now sell E20, leaving unblended 100-octane fuel available only at select outlets at roughly double the price.
