I have used s.b. fuel stabilizer for my small engines for years. can i use 'fast fix' as a fuel additive in every tank of gas along with the stbilizr?

Sure. Although this product is designed more specifically for reactive and immediate use (e.g. while starting the engine after storage, having performance issues, or rough/no starts). However, it can certainly be used with STA-BIL Brand at the same time -during use or storage. Hope this helps. Please feel free to contact us at producttechsupport@goldeagle.com. Thanks for the question!

do you pour it unmixed into the small engine?

Need to clear up the directions for this product. You say 1oz per 2.5 gallons or gas then show pouring directly into gas tank on a mower. Obviously no mower tank is 2.5 gallons so people automatically revert to thinking to mix it into their red 2.5 gallon gas container. I realize you can do this too but y’all really need to clarify this. Like “1oz into mower tank is good for 2.5 gallons of run time” something like that

Do I pore it in the gas tank on my rovan Baja gas rc or mix it with gas just asking

Either would work but I just poured it in the tank and it worked well

Great

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.

It works

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
