Ethanol gas

  1. Sep 15, 2008 #1
    Dear all,

    They starts to sell ethanol gas in my town. It is only 5% ethanol as said. Concerning the power of the car, I think it's about the same. But I am not sure about the durability of some item, may it reduce the lifetime of some parts?.

    Thanks for all of your contribution.

    High concentrations of ethanol can have an effect on some plastics and the ignition system needs to be adjusted for the different behaviour.
    But 5% ethanol has almost no effect, it's probably within the range of composition of regular gasoline!

    All modern car engines should be able to run on up to 10% ethanol without problem. (http://en.wikipedia.org/wiki/Ethanol_fuel).

    Indeed, you can look on the pumps for regular gasoline. I've seen them as high as 10% ethanol IIRC.
