Fuel additives to help the performance of your vehicle.

Using this product with the minimum mixture may have provided some performance gains. Using the Maximum mixture rate with my pre mix caused the bike to over rev on its own for no reason. Even using the kill switch would not shut the bike off. I had to stall the bike to kill the engine. Im not sure if there was any benifit for for me. Though it did give the exhaust that high performance race smell. I wont ever use it again, and will only run 110 race fuel instead of mixing this product with 92 octane. <span>Additional Comments On Aug 18, 2010:</span>The review above was meant for a different Klotz product. Now for the real review. This stuff works well. But Im not sure if Im saving any money by using this stuff or paying the extra money for the race gas.

This is the only fuel stabilizer that I'll buy. I've never had any issues with it during many years of use.

I started using this exclusively after the needle valve got stuck in the WR250f. So far it keeps the ethanol from destroying both my carbs. Only time will tell but I'm happy to this point.
