    Sunoco Race Fuel

    What are people's thoughts on Sunoco race fuel? I looked through this thread on VP vs Sunoco.

    Any further thoughts? I need race fuel for the 1010 but Sunoco is available to me about 10 minutes away but VP is a good hour to hour and a half from me.

    I tried the Sunoco unleaded (104 or 105 octane) one year at the World Finals and it blew up one ski and almost blew up the second. Back when I raced, I used Phillips B66. Now that they have merged with Conoco, I don't know what they offer. In my experience, VP is somewhere in between.

    Was it a bad batch? Ever find the reason behind your problem?

    It burned hotter than the Phillips I had used all season. It burned a piston in my 96 Sea-Doo XP Limited class ski and my Pro 785 ran like crap. I couldn't get it properly tuned. I think Sunoco has more fule options these days though then they did back then.

    I've used their 110 for many years. Never had a problem with it. Much cheaper than VP, and available a few miles down the road from me.

    I'm now a Sunuco fan after my experience with 210 pounds compression with my Matrix. The engine should not have made it an hour but damn if it didn't run all 4 days.
    There was no VP110 around so I ran the Sunuco 112. It supposed to be more like 120 due to the oxygenation. A small carb adjustment and all was good.

    How small of an adjustment?

    I would be using the 112 supreme or 110 standard, which either isn't oxygenated.

    I wound up aprox 1/4-1/2 turn more fuel on top and about 1/16 on the lowers.
    Yours may not need any changes, keep an eye on things.

    Okay next question: How long does the Sunoco stay fresh? Probably wouldn't hurt to put in some Stabil in the gas tank after I ride it since I really don't know when the next time I would be able to ride.

    Av gas and racing fuels stay good for a long time. Much more stabile than pump gas. A guy I know uses avgas in his boat to winterize the tank, and also uses it in his fork lift that rarely gets used, but will always fire right up after long idle periods.
