E20 Fuel May Damage Rubber Parts in E10 Cars, Said Unpublished Report The Indian government's push to switch to more environmentally friendly fuel blends has hit a snag due to an unpublished report by the Automotive Research Association of India (ARAI).
The study recommends rolling out E20 fuel but warns that using this higher ethanol blend in cars compliant with the earlier E10 standard can cause significant damage to rubber parts.
The problem lies in the government's failure to consider the potential consequences of mixing incompatible fuels.
