    So I procrastinated long enough that the local shop is out of u4.4. That I need for this weekend. Bike is tuned for this fuel. Supersport built Daytona 675.
    Are there any other VP fuels that would work as an alternative? T4, vpr, ms109?

    T4 is 100 octane. It has some oxygenation as well.
    I so very small differences on the Dyno between the two.

    Sounds like T4.
    Anyone have experience with ms109? That's what the vp dealer is recommending.

    Spec sheet indicates almost twice the oxygenation for ms109.
    101 octane. Ms109 is about $100 for a pail and T4 is about $90.

    On a side note. Does anyone have the secret decoder ring to decipher the vp date code. The old code was much simpler.

    PM Chuck Ivey. He’s the resident slinger for VP fuels in these parts.

    There are some shops in Indiana that carry it, but very few. There is a hub in Terre Haute that might have some. There again, Chuck would know more.
