sredish Posted March 7, 2009 Report Share Posted March 7, 2009 (edited) ok I'm riding tomorrow and I can't find race gas can I use octane booster with my gas, if so how much and what kind? you can use octane booster, but it's very likely that you won't find a booster that works how you need it. they only do in points of octane, not full octane. if it says 3 to 5 points it would be like 0.3 to 0.5 octane boost, so not even a full octane. You can add toluene (aka methylbenzene) or xylene if you're in a jam. Xylene might be easier to find (with the paint thinners) in a typical hardware store or paint store like Sherwin Williams. Mix it 10% - 30% with pump gas, then add your oil to it. It might throw the jetting off some and expect poor cold start performance with the more concentrated mixtures. 4 quarts in a gallon, so there's your 25% mixture. To make a 5 gallon mixture, take 4 gallons of pump and 4 quarts (1 gallon) of Toulene or Xylene. Edited March 7, 2009 by sredish Quote Link to comment Share on other sites More sharing options...
