The debate over India's E20 fuel rollout has intensified, with the Opposition questioning the government's push for higher ethanol blending and raising concerns over its impact on vehicles and consumers.

Maruti Suzuki said extensive testing found no evidence of excessive wear, corrosion or damage from E20 fuel, while Toyota described ethanol as a clean, high-performance fuel that offers good drivability and is even used in Formula One racing.
