I have a BS-IV Hero Duet bought in 2017. I was thinking about upgrading to the Hero Xoom 125, which is compatible with E20 petrol. But now I have learnt that the government may roll out higher ethanol blends. What should I do?

We'd advise you to go ahead with your new scooter's purchase because for the short to mid-term, E20 will be the current baseline blend of petrol available on a nationwide scale. Speaking strictly about material compatibility, E20 machines should be able to handle up to E30 fuel with the fuel tank, rubber seals, gaskets and hoses all ready to support the higher blend. What will need recalibration is the ECU to handle the higher ethanol content in the fuel, which is something that will have to come from the manufacturer.
