    Unleaded regular. If your engine has the slant spark plug hole, you may need to use unleaded plus for the additional compression.

    If you have a slant cylinder head, use the highest octange (ethanol free) pump fuel you can get.

    if you have a straight plug cylinder head, you can use any (ethanol free) pump fuel of your choice.

    I use 25:1 (5.4 oz or 2/3 cups) 2-stroke oil in a gallon can of premium gas and run the whole gallon through for break-in.
    From there I run 32:1 (4 oz or 1/2 cup) per gallon of good gas.

    It's not the higher octane you are looking for, all octane does is keep high performance engines for pre-firing and 'knocking'.
    The highest grade fuel as mentioned above usually contains less Ethanol.
    Ethanol is not our friend with 2-stroke bikes.

    Considering it is only pennies more why not right?
