The Centre has informed that some rubber parts in BS-III vehicles may wear out faster when these vehicles are regularly operated with E20 fuel. Vehicle owners have been advised to follow the manufacturer's guidelines and replace affected rubber components if needed to ensure safe and smooth performance. Centre Issues Advisory on E20 Fuel Use in Older Vehicles The Central Government has said that BS-III vehicles may need extra attention if they are used with E20 fuel. E20 is a blend of 20% ethanol and 80% petrol, introduced to reduce fuel imports and lower vehicle emissions. According to the government, some older vehicles, especially those built under BS-III emission standards, were not originally designed to run on higher ethanol blends. Because of this, certain rubber parts such as fuel hoses, seals, gaskets, and O-rings may wear out, crack, or lose flexibility over time. Officials clarified that this does not mean every BS-III vehicle will face problems immediately. However, regular inspection and timely replacement of worn-out rubber components may be necessary for vehicles that frequently use E20 fuel. Why Can E20 Fuel Affect Rubber Parts? Ethanol has different chemical properties compared to regular petrol. It can interact with older rubber materials used in fuel systems, especially in vehicles manufactured before E20 compatibility became common. Over time, this may lead to: Cracking of rubber fuel hoses Damage to seals and gaskets Fuel leakage if worn parts are not replaced Reduced fuel system efficiency Experts say that newer vehicles are generally designed with ethanol-compatible materials, while many older vehicles may require maintenance upgrades to continue operating safely with E20 fuel. What Should Vehicle Owners Do? Vehicle owners have been advised not to panic but to stay alert. If a BS-III vehicle is regularly using E20 fuel, owners should: Get the fuel system inspected during routine servicing. Replace damaged or worn rubber parts immediately. Follow the maintenance schedule recommended by the vehicle manufacturer. Visit an authorized service centre if any fuel leakage, unusual smell, or engine performance issue is noticed. Routine maintenance can help avoid larger repair costs and improve vehicle safety. Government Continues Push for Cleaner Fuels India has been promoting ethanol-blended petrol as part of its clean energy and energy security goals. The use of E20 fuel is expected to reduce dependence on imported crude oil and lower carbon emissions from vehicles. The government has also encouraged automobile manufacturers to develop vehicles that are fully compatible with higher ethanol blends. Many newer models already support E20 fuel without requiring major modifications. For owners of older BS-III vehicles, the latest advisory is mainly a reminder that preventive maintenance is important. Replacing aging rubber components when required can help keep vehicles running safely while supporting the country's transition toward cleaner transportation. Although E20 fuel offers environmental and economic benefits, vehicle compatibility remains an important factor. Regular servicing, timely replacement of worn rubber parts, and following manufacturer recommendations will help BS-III vehicle owners continue using their vehicles safely as India expands the use of ethanol-blended fuel.
