The RTR Ethanol runs on E85 ethanol that is an oxygenated fuel similar to petrol but made from plant matter. Most petrol engines can be run on ethanol but need revised changes to the fuel system, that allows them to run with the higher air-fuel mixture that ethanol requires. And helping with that change is the twin-spray-twin-port fuel injectors that the RTR Ethanol is equipped with. If we talk about the mileage it will return about 22 to 23 kmpl. As government hasn't initiated ethanol fuel stations so we have to wait for its launch till we get ethanol fuel pumps in the country.
