E20 compatibility explained: Which vehicles may need part replacements, what govt told Parliament

Government clarified that E20 fuel does not require engine modifications for cars and two-wheelers based on studies by IOCL, IIP, SIAM and ARAI.

Some BS-III vehicles introduced from April 1, 2005, and manufactured before 2016 may require replacement of rubber parts and gaskets during routine servicing.

Centre stated that vehicle mileage depends on multiple factors beyond fuel type.
