E10 petrol Comeback? Govt Explores Premium Fuel Option for Older Cars India’s E20 rollout may soon get a limited alternative for motorists worried about mileage and compatibility. The petroleum ministry is discussing whether state-run oil marketing companies can offer a lower-ethanol option through their 95-octane fuel network, according to reports published on August 27, 2026.

The proposal is still at an early stage. Indian Oil Corporation, Bharat Petroleum Corporation Ltd and Hindustan Petroleum Corporation Ltd are reportedly examining whether their 95-octane products can be supplied with 10% ethanol instead of the current E20 formulation. If approved, the move would not replace E20 as India’s standard fuel. Instead, it could create a costlier choice for drivers whose cars and two-wheelers were originally designed around lower ethanol levels.

Why E10 petrol could matter for motorists

For many owners of pre-2023 cars and two-wheelers, the debate over E20 is primarily about mileage, compatibility and long-term running costs. These older vehicles were generally designed or certified around E10-era fuel standards, while E20 contains twice as much ethanol. A lower ethanol blend could therefore give motorists another option without forcing the government to reverse its broader biofuel programme. The idea being explored is to use the existing 95-octane distribution network rather than create a separate national storage and dispensing system.

That matters because the infrastructure already exists. According to Hindustan Times, premium 95-octane products are available across a large part of the public-sector retail network. This could make a limited E10 petrol rollout easier than bringing back multiple regular-grade fuels nationwide.

Why the government is reconsidering a lower ethanol blend

The latest discussions follow weeks of pressure over E20 and its effect on older vehicles. On August 17, Chief Economic Adviser V Anantha Nageswaran argued that India should restore a lower-blend fuel alongside E20. Reuters reported that he supported greater consumer choice, particularly while concerns around older engines and components remain unresolved for some motorists.

That position stood out because the Centre had publicly resisted a rollback only weeks earlier. In July, Minister of State for Petroleum and Natural Gas Suresh Gopi said there was no proposal to revert to E0 or E10 nationwide. The government argued that running several parallel fuel streams would increase logistics, storage and handling costs. The new proposal appears to be an attempt to find a middle path: retain E20 as the default while offering a targeted alternative through an existing high-octane network.

What this could mean for premium petrol price

The biggest unanswered question is cost. Hindustan Times, citing Mint, reported that 95-octane products such as XP95, SPEED and Power95 can cost about ₹110–₹115 per litre in Delhi, compared with roughly ₹102 for regular petrol. Actual rates vary by city and retailer. If these products are converted to a 10% ethanol formulation, motorists may have to weigh better compatibility against a higher premium petrol price. For a driver covering long distances, the calculation would depend on whether any improvement in fuel efficiency is large enough to offset the extra amount paid per litre.

That price gap could become central to whether consumers actually adopt the option. A technically suitable fuel will have limited appeal if the extra cost is greater than the savings motorists expect from improved mileage. The petroleum ministry and oil companies have not announced a final pricing structure. If E10 petrol is introduced through these 95-octane products, the retail premium will be a key part of the consumer decision.

What officials say about E20 mileage

The government continues to defend E20 as safe for widespread use. In written replies to Parliament reported on July 30, 2026, Union Road Transport and Highways Minister Nitin Gadkari said E20 may reduce fuel efficiency by about 2% to 6%, depending on vehicle category and age. He also said government and industry testing had not shown engine failures attributable to E20.

Separately, the Centre told Parliament in July that mileage reduction in some E10-designed vehicles was generally around 3% to 5%. It said testing and field experience had not established widespread engine damage linked to compliant ethanol blended petrol. Maruti Suzuki has made a similar argument. At a July 4 government-industry briefing, senior executive Rahul Bharti said the company had tested E10-era cars on E20 and found no major concerns across the parameters examined. He said the lower energy content of E20 could create a mileage impact of roughly 3% to 3.5%.

Owners report a sharper mileage drop

Consumer surveys present a less reassuring picture. A LocalCircles survey reported in July found that 66% of owners of petrol vehicles manufactured before 2023 said their mileage had fallen by more than 10% since early 2025. India Today also reported that independent real-world assessments cited by LocalCircles placed mileage losses for some older cars closer to 8% to 12%, above laboratory estimates.

These figures are self-reported or survey-based and should not be treated as proof that E20 causes the same loss in every vehicle. Driving style, traffic, tyre pressure, maintenance and vehicle condition can all affect fuel efficiency. Still, the complaints help explain why demand for a lower ethanol blend has persisted. They also show why some consumers may be willing to pay more for premium petrol if they believe it offers a better match for their engines.

What happens next

For now, E20 remains the standard petrol available across India, and the government has not formally restored E10 petrol as a nationwide alternative. The discussions with Indian Oil, BPCL and HPCL are exploratory. If the plan moves ahead, the likely model is a limited 95-octane option aimed primarily at owners of older vehicles rather than a reversal of India’s ethanol programme. The final decision will depend on logistics, consumer demand, pricing and how oil companies position the product. Until an official notification arrives, motorists should treat the proposed switch as a policy option under consideration, not a confirmed change at the pump.
