BS-III vehicles may need rubber parts replacement for E20 fuel: Gadkari

The government said some rubber parts and gaskets in BS-III vehicles (manufactured before 2016) may need replacement when using E20 petrol, but engine modifications are unnecessary. Studies by IOCL, IIP, SIAM, and ARAI found no significant performance or wear issues. The statement comes amid criticism of the E20 rollout by opposition and consumer groups.
