New Delhi: With E20 petrol becoming widely available across fuel stations in India a major wave of concern has emerged among vehicle owners. Drivers of older BS3 and BS4 model cars are increasingly worried about the potential impact of this new fuel blend on their engine health and overall vehicle performance.
The newly introduced E20 petrol contains eighty percent regular petrol mixed with twenty percent ethanol. Ethanol is an alcohol based biofuel primarily extracted from sugarcane corn and other agricultural crops. The central government is actively promoting this fuel alternative to reduce the heavy national dependency on imported crude oil while simultaneously benefiting local farmers and curbing environmental pollution.
While modern vehicles launched after April 2023 come equipped with engines and fuel systems specifically engineered to handle the E20 blend older vehicles face certain mechanical challenges. Automobile experts suggest that using this blended fuel over a long period in cars not specifically designed for it could lead to premature wear and tear. Specific engine components like rubber hoses gaskets fuel pipes seals and O rings might degrade faster due to the chemical properties of ethanol. However experts clarify that filling up with E20 will not cause immediate engine failure but it definitely demands more vigilant vehicle maintenance.
Another notable concern for regular commuters is a potential drop in fuel efficiency. Since ethanol naturally contains slightly less energy compared to pure petrol users might notice a marginal reduction in their daily vehicle mileage. The exact drop largely depends on the current condition of the vehicle its engine tuning regular maintenance and the personal driving style of the owner.
For owners of BS3 and BS4 vehicles the primary advice is to avoid unnecessary panic. Industry mechanics recommend adhering to a strict and regular servicing schedule with a special focus on inspecting the entire fuel system. If drivers notice any unusual engine sounds starting difficulties or a sudden drop in fuel efficiency they should immediately visit an authorized service centre for a thorough checkup. Proper and timely maintenance will easily help older cars adapt safely to this changing fuel landscape.
