    Can I use premium gas in my China made 2 stroke...Are there any advantages or disadvantages to using higher octane fuel...New to motorbiking and just trying to feel my way along. Thanks

    there was a discussion on this a while back. it seems most agree that with such low compression 87 octane is best. while at bonneville augi used 110 mix and after the trials were over a man from salt lake told us he thought augi should have stayed with 87.

    My Zbox instructions say to use 91 octane, and not the 10% ethanol blend.

    Waste of money. I use 85 octane with 10% ethanol blended fuel.

    I use 87 octane with 1 cup of seafoam per gallon. Varoom, varoom :grin:

    And that 10 bucks is kept in my pocket and one of the many reasons why I am not an average american with 9,800 dollars in credit card debt. I have none.

    10 bucks is more than most folks make in an hour and is an amount that should not be laughed out. The journey to retiring rich begins with a penny.

    Argue all you like. Being Brothers, I give it to you striaght.

    I removed my base gasket (between jug and lower end) on my HT. This lowered CC's but upped compression drastically. Caution don't do this as a performance mod unless you can read a micrometer and know your head and plug won't be smashed by your piston!

    I followed all instructions on many links(to avoid DMV Nazi's) in NYS... I wanted my bike quiet!!! Fin spacers, packed exaust,clutch plate cardboard,ect. The one thing that made a real difference is I put 93 octane in the bike. It ran smoother, COOLER and quieter than ever...

    I can't believe the difference it made. My motor is newer with higher compression than normal.

    On an older motor I'd say stick with lower octane. Lower octane burns hotter, wasting energy(by not requiring higher compression), it also makes the motor easier to start. Mine runs great on 93. If you live somewhere hot, run 93 or better. Your motor (car or HT) will run cooler.

    In Buffalo, winter, I run 87 for easy start and 93 in summer for cooler run.

    I always run super/premium. Have since day one. Most of the time it's 10% ethanol, but meh. It's the closest service station.

    High octane gas does not make the engine run cooler..that is silly. It does allow the engine to tolerate higher temperatures better.
