About a month ago, we had a big 50 lap atv race in VT. I put about 1/2 of the tank full with C16 Racing Fuel, which is meant for cars. I have never done this before. The other 1/2 was regular fuel. Will it really harm the engine if i keep doing this. It was in my 2003 250ex btw.

nope, you should be good to go. you can basically say that you're running 103.5 octane with the half and half mix, assuming that the pump gas is 91 octane. how were the results of running that?Originally posted by Tater049

yea it was 91 octane. And omg there was a really good increase. The race was during a rain storm that we got around 3 inches of rain. So there was a ****load of mud everywhere. The engine was ripping and it performed great. I want to do it again the next race, because it was so good.

I dont see how you saw any performance increase if you're running a stock piston. I never saw any difference between 87 and 93.
