India’s E20 petrol mandate faces consumer protests over mileage and engine-damage concerns. The government and automakers Maruti Suzuki, Hero MotoCorp and Toyota India say testing and service data show no widespread E20-related failures, while multiple fuel grades are deemed operationally difficult.
