Put it in a lawn tractor. Let it sit overnight. Started the next morning and was still running a bit rough. Started cutting the lawn and could hear tractor running smoother. Before adding it. Tractor would run and die a few minutes later. Now just a touch of the key and it fires right up. Before it would whirl over for a bit and finally start.

This stuff works!! I put it in my 3 lawn mowers and a gasoline generator and all 4 seem to be easier to start and run better, the 3 mowers have more power! Will buy again if needed.

Seems to work well and cleans out my small-engine fuel systems.

Product work as instructed! I used 2 ounces to 10ltrs to fix idle on 9.9hp Yamaha outboard idle issue! Left the 91 fuel in 8months and it turned to varnish blocking up idle circuits! Made new batch of 10ltrs of 95 fuel and two ounces of Fast Fix and run for 30min and it fixed it perfectly 10/10

Worked very well,very satisfied.
