Overview
- The Centre told Parliament on Monday that it has not assessed what share of India’s vehicles are fully compatible with E20 petrol, a gap it acknowledged in a written Rajya Sabha reply.
- The government cited laboratory studies, field trials by ARAI, SIAM, IIP and manufacturers, and large OEM service data covering 2.84 crore vehicles to assert E20’s safety and absence of verified ethanol-linked corrosion.
- Officials said E20 raises octane and cuts carbon emissions by about 30% versus E10 while warning older, E10‑calibrated vehicles may see a roughly 3–5% drop in fuel economy.
- Public complaints and polling report widespread mileage and maintenance worries, transport associations have announced a Parliament march for August 4, and Minister Nitin Gadkari won court permission to sue platforms over posts linking him to E20.
- The combination of government assurances, unresolved fleet‑compatibility data and rising protests has sharpened demands for independent fuel testing, clearer consumer choices at pumps and scrutiny of warranty and liability practices.
