    96 hurricane & sl750 fuel octane rating

    I usually fill my skis with 93 octane fuel, but I am going to be using ALOT of fuel in the next few days, so if I can run less then 93 octane that would be great! I tried searching for the required octane rating for a 96 hurricane, but I keep finding threads about the "octane". So what is the minimun octane rating for a hurricane?

    Also you can run 87 octane in a stock fuji 750 right?

    My owners manual shows 87 octane minimum.
    Right or wrong, I run 89 or 91 just because todays fuels are so crappy and I don't want a deto problem.

    89 Octane is recommended minimum by Polaris if the fuel is oxygenated (ie: has Ethanol mixed in).

    87 Octane only applies to non-oxygenated fuel, if you can find any these days.

    I would say you need to stay at 89 octane or better. If you cannot find 89 at the pump, you can mix regular 87 with premium, and average the octane down to 89.

    Not an exact science, but 50% 91 octane, and 50% 87 octane, would get you close.

    Interestingly, often the premium octane grade gasolines have less, or no, Ethanol in the fuel mix, while regular grade gasoline has the highest percentage of Ethanol.

    If your engine has higher than stock compression, then you should think about using octane higher than 89.

    I just ran a compression test on my ski and it read 140 psi on each cylinder. What octane should I use?

    I would agree, run 89 octane or better, with better being a good idea.

    The difference between 87 and 93 octane is about $.20 a gallon or $2 a tank.

    Not worth the chance if you ask me.

    Does running a higher octane have any effect on performance??

    Marginal or no improvement in performance, with these 2-stroke engines.

    Peace of mind can be considerably better, however!

    I don't think you guys understand ethonal. Ethinal actually is a higher octain. I run it in my subaru wrx for higher boost. In mn we can buy E85 for about 3.00 a gallon. And e85 is about 104 octain. The only problem with e85 is that it burns less efficent. So you need to run more fuel. I have about a 20 percent injector scale difference in my pump gas vs my e85 tune in my car.
