Experts warn that high ethanol blend levels could damage vehicle engines

According to Prof. G. Krishnamurthy, Head of the Chemistry Department at Bengaluru University, high levels of ethanol blend could damage vehicle engines. He stated that a 20% ethanol blend is suitable for common vehicle engines, while some modified engines can handle 25% to 30%. Prof. Krishnamurthy added that using ethanol must align with the vehicle's engine design, as higher blends may reduce mileage.
