Overview

• India says it reached 20% ethanol blending ahead of schedule and has expanded E20 petrol availability nationwide.
• Vehicle owners, especially with pre‑2023 models, report lower fuel economy and component wear, and one insurer warned that damage from using the wrong fuel would not be covered.
• The Petroleum Ministry states E20 does not affect insurance validity and found no major engine damage, estimating mileage dips of 1–2% in newer cars and up to about 6% in older ones, though detailed test data has not been released.
• Manufacturers and retailers have issued mixed guidance, with some cautioning older vehicles may need retrofits or risk warranty issues, and Maruti Suzuki preparing E20 upgrade kits as others assess compatibility.
• Consumer pressure for pump choices is growing as premium zero‑ethanol fuels remain costly and scarce, a LocalCircles poll shows about 66% opposition to the rollout, and decisions on blends beyond E20 await an inter‑ministerial report after October 31, 2026.
