I run a supercharged v8 . Yes dual exhaust , even methanol injection , snow system , i use 93 octane sunoco etc. . It is a sleeper . I find it difficult to get consistant gas . I can monitor the motor and see when knock sensor is cutting back , indicating a knock condition . First what your not going to see , smoking tires , whiplash power increase . What i see is less timing change because of poor fuel , smoother motor , reduced hesitation etc. You donot need a lot and running more is not going to make a huge difference . Unless your anal and have a lap top hooked up , like me , you maynot feel a big change . It does smooth out idle, seems to burn really clean , much better than just pump gas with out klotz. Is it worth it , ? to me yes . I think anyone into performance will notice it . Yes , small motors , like lawn , chainsaws etc , will run better, even cooler , cleaner, just don't over dose them . Start with half of recommendations . Don't expect your prius to out run a vette if you use it

I use this stuff in all my small engines. Chain saw, snow blower, weed eater. I use it in my 2 cycle atv and boat. This stuff is horse power in a bottle and you can feel it. These hard working small engines defiantly will increase power just like the label says. Helps these small engines start way better too. Makes the Gas more explosive. Read and follow directions. If you put in to much the motor will run on. This happen to me on my weed eater that use to be hard to start. If run on occurs just add gas to dilute. Start with a small amount and work up. Like a chain saw I'd put in one or two cap lid fulls to help start. If you wanted more power maybe 3 or more. Just work your way up a little at a time. In my 90 hp Yamaha boat I run 3 oz. to the gallon.
