Overview
- This week the Ministry of Petroleum and Natural Gas published a detailed 10-point clarification that called social‑media claims about engine damage, insect attraction, warranty voids and extreme water use false and scientifically unfounded.
- The ministry cited ARAI‑led trials with IOCL, IIP‑Dehradun and SIAM that ran about 40,000 km on passenger cars and 20,000 km on two‑wheelers and reported no major drivability or material‑compatibility problems.
- Officials and automakers said mileage changes are marginal and vehicles built or certified for E20 remain covered by warranties and insurance when used according to manufacturer guidance, although some older rubber parts may need earlier replacement.
- The government rejected the 10,000‑litres‑per‑litre water claim and said distilleries typically use about 3–5 litres of processed water per litre, many employ Zero Liquid Discharge systems, and maize now supplies over 40% of ethanol feedstock.
- Despite official rebuttals and industry briefings, isolated consumer complaints and political concerns continue, Bhutan declined an E20 offer citing storage issues, and officials say any move beyond E20 will follow further testing and consultation.
