Government Exempts E22 to E30 Ethanol Blends From Excise Duty: A Solution Without Cars
The Indian government has exempted petrol blended with 22, 25, 27 and 30 percent ethanol from central excise duty. The Bureau of Indian Standards notified specifications for these blends on May 19, but none of them is currently sold at fuel stations. The exemption is meant to make higher blends commercially viable once supply chains develop.
What was announced
The Ministry of Finance has notified a central excise duty exemption on petrol blended with ethanol at concentrations of 22, 25, 27 and 30 percent, designated E22, E25, E27 and E30. The Bureau of Indian Standards finalised the fuel standards for these four blends on May 19, 2026. None of them is currently retailed at fuel stations in India, and the exemption is intended to make higher blends more commercially attractive to oil marketing companies and dealers once the supply chain is in place.
Exempting fuels nobody sells, for cars not certified to run them, is policy theatre until oil companies stock the pumps and carmakers approve the engines.
For context, E20, which contains 20 percent ethanol, is the current baseline for petrol sold in India and retails at Rs 102.12 per litre in Delhi as of June 11, 2026. With excise duty removed, E22 through E30 could land below that benchmark at the pump whenever they go on sale. The BIS, in its standards notification, said the move "aims to promote cleaner transportation, enhance energy security, reduce crude oil imports and support the agriculture sector" following the achievement of the E20 blending target.
This announcement comes days after the government separately introduced E85, a blend of 85 percent ethanol, on June 5. The Centre has also set a target of 500 E85 dispensing stations operational by the end of 2026. No timeline has been published for nationwide rollout of E22, E25, E27 or E30, and no list of compatible vehicles has been issued by carmakers.
The Car Jury verdict
This is policy running far ahead of the pump and the parc. None of E22, E25, E27 or E30 is actually on sale, and the cars on Indian roads were certified for E20 at best, with most older cars warranted only up to E10. An excise sweetener is meaningless until oil marketing companies actually stock these fuels and carmakers certify engines and fuel systems for them.
The real concern is the silence on compatibility. Higher ethanol content attacks rubber seals, eats into fuel economy and can corrode fuel system components not designed for it. As Gagan Choudhary of MotorOctane has noted about Maruti, "there's Maruti's simple funda to work great in the engine department"; that engineering discipline now has to extend across the industry to E30-ready hardware. Until then, this exemption is a press release. Buyers should ignore it and stick to what their owner's manual permits. Read our Maruti Swift verdict for an E20-ready petrol that makes sense today.
