How do I convert my cars gasoline engine to ethanol or E-85 (2005 Hyundai Elantra)?
Cars that run on E-85 are specially calibrated so that the fuel sensors in the engine “sense” the energy level in the fuel. Since E85 cars can run on anything from pure gasoline all the way up to E85, the engine needs to be able to detect the amount of energy in the fuel you’re putting in. The “rubber parts” do not need to be replaced. All newer cars (those built after 1980) can handle ethanol. The only thing you may need to do more often if you put ethanol in an older car is change the fuel filter. Ethanol tends to clean out gunk and make the engine perform better. I would not recommend converting a car to accept E85 because it could void your manufacturer’s warranty.
