Thread: Wet head fuel octane level

  1. #16
    Part of my reasoning is quality of the fuel you are getting. Many tanks have one hose for all three levels. How much fuel is in the hose before you get what you want. I have tried lower octane fuel and haven't noticed any difference. However I didn't do a scientific study, i.e. making sure all the environmental and performance factors were the same.

    Octane level

    Is the recommended fuel for the wethead RT not also 89 AKI?
    Thanks for the information. I don't mind paying for 91 or 93 octane fuel but, if you get 87 octane you can rest assured that the fuel is fresh. Some stations sell very little high octane fuel, especially in the rural parts of this country and that fuel can be stale and watered down. Speaking from experience.

    This place is on the south-ish side of the base of Hood, on 26 or 35... will have to research if you're really interested. It's a hole... walking in you would (be scared) never believe you would eat something that would leave you wanting to come back, for years!

    So true... and why so many in rural areas don't carry it as it's real expensive to have that kind of volume separate and have to be disposed - double whammy.
