    Hey guys i am currently running the lowest quality fuel which is classified as E-10 i was wondering:thinking: whether or not my little china 2 stroke would handle the 91 unleaded fuel as i don't wanna put it in the fuel tank just in case i destroy my motor. Any feed back is much appreciated.

    Kind regards Markham26

    yes it'll run on the 91 octane, but it will probably run better with the cheaper stuff (here in the U.S. we have 87 octane as the cheap stuff).
    the compression in the china engines is very low, so cheap gas is the way to go.
    you will not gain anything by using the 91 octane, but you will lose money....right out the exhaust.

    I tried the good stuff and it ran worse than ever. I always "assumed" higher octane fuel burned hotter, so it should run better. After a little research. It turns out the higher the octane the less combustible it really is allowing for higher compression before ignition. ie high comp racing engines.

    I do not have a high comp head yet, so there may be a difference. I doubt we'll ever get high enough compression for this to be effective.

    A friend of mine I ride with alot has used a little ether in his fuel with very good results all summer "probly 400+ miles" a nyquil measuring cup so what 2 tsp-per-tank. Burning hotter (read)more combustible would be a good thing. I haven't tried it yet so I can't recommend or not, gonna try tho :)

    australia uses a different rating system to the usa. our 91 (or unleaded) is the same as there 89. and our 95 is the same as there 91 and our 98 is the same as there 93
