Ok, I tried this stuff, about $7 a pint, enough for about 5 gallon of premix. I want to post my findings. This stuff really works. I had a very carboned up Polaris atv, two stroke 250. I tried several products without any difference, MM oil and Sea foam, after only two tanks of this golden nectar. It noticable runs better and idles nicer. It smoked terribly for awhile but now has leveled off. I give this product thumbs up. My only complaint, is it is not dyed and it would be easy to lose track of if you have multiple cans and does not identify itsself as premix. Still good stuff and easier than a teardown and de-carbonize.
