Hyderabad Motorists Voice Concerns Over Vehicle Damage From E20 Ethanol Petrol

The rollout of E20 ethanol-blended petrol has sparked significant concern among motorists in Hyderabad, particularly in areas like Alwal, Domalguda, and Gachibowli, over potential vehicle corrosion and reduced fuel mileage. Following the state-wide transition to the standard 20 per cent ethanol blend, local vehicle owners expressed anxiety regarding the long-term impact on their engines and the lack of alternative fuel choices at local filling stations as of July 4, 2026.

The E20 fuel, which comprises 20 per cent ethanol blended with 80 per cent petrol, has become the standard across Telangana as distributors implement the blending process. While the government strongly pushes for even higher blends like E35 and E85, local motorists fear that their current vehicles are incompatible with the fuel, which could lead to internal corrosion, compromised performance, and dropped mileage.

Dinesh Naganoori, who commutes daily from Domalguda to Gachibowli, argued that consumers should be given a choice rather than being forced to buy a single blended option. Currently, petrol pumps across the state only sell the ethanol-blended variety. Many motorists are waiting for E20-compatible conversion kits equipped with ethanol-resistant fuel lines, gaskets, and rubber fittings to protect their vehicles.

There is also a common misconception among local drivers that high-octane fuels, marketed as "Power Petrol" or "XP95," do not contain ethanol. However, these premium fuels, which feature octane ratings between 93 and 97 compared to the regular 91, are also blended with 20 per cent ethanol. While they contain additives to clean carbon build-up and prevent premature ignition, they do not offer an escape from ethanol blending.

Motorcycle enthusiast Kishore Kumar noted that the mileage of his vehicle had been slightly affected by the blended fuel, though he acknowledged that heavy city traffic also played a role.

Meanwhile, some automotive technicians advise patience. Shaik Karim, a two-wheeler mechanic operating in Alwal, stated that he had not yet received any complaints regarding the blended fuel. Karim noted that it was too early to definitively speak on ethanol-induced corrosion, adding that mechanics would need at least another six months to observe any tangible issues in vehicles.

The aggressive push for ethanol blending, spearheaded by Union Minister for Transport Nitin Gadkari, has faced widespread criticism, with some alleging the policy is driven by personal interests.
