With India’s ethanol blending programme moving towards higher E20 fuel usage, vehicle owners with older, non-compliant models are facing concerns over fuel compatibility and manufacturer warranties. As oil companies transition to supplying only E20 petrol, some automakers are exploring solutions to help existing customers adapt.
Maruti Suzuki is planning to introduce E20 material upgrade kits for models up to 10–15 years old. These kits would replace fuel system components such as metal parts, rubber seals and plastic elements that could degrade when exposed to higher ethanol content. Prices are expected to range between Rs. 4000 and Rs. 6000, varying by model. It is not yet clear if any subsidies will be provided to offset costs.
While converting a vehicle to E20 compliance is technically achievable from a material standpoint, it requires testing and validation, especially for engines that are no longer in production. Beyond material changes, fine-tuning the engine to maintain emission compliance may also be necessary.
Industry observers note that other manufacturers are also evaluating similar upgrade initiatives, which could provide relief for owners of non-E20-compliant vehicles in the coming years.
