I used some old gas in my lawn mower and the engine would not start. So I drained the old gas, put in new gas and added an ounce of Sta-Bil Fast Fix into the gas tank and let it sit over night. The next day the engine started right up. I highly recommend this Sta-Bil product.

Had the classic situation of a generator (ie. small engine) with a carburetor and both jets gummed up by E10 fuel. I was able to clean the carb and 1 of the 2 jets manually, but couldn't figure out how to pull the 2nd jet to clean it. Generator ran better after cleaning, but still surged a lot / ran rough. Put this Fast Fix stuff in the tank and ran it for 5 to 10 minutes and the engine ran more and more evenly. Still can't push the choke all the way back in after starting (have to carefully set the choke to get it to run smoothly, but it's way better than before.) It's not magic, but it does seem to work well enough. If you can't work on your engine yourself or don't have a small engine mechanic nearby, it's definitely worth a shot.

It really does work, my old Briggs push mower was stuttering really badly, put some fresh gas and some of this treatment in the tank. Ran really rough for a few minutes, but after about 20 minutes of running, she was running like new again. Good place to start if you don't want to pull the carb off and clean it manually.

I was having some issues with my self propelled walk behind lawn mower recently. It would fire right up on the first pull, but when I would turn the engine off to empty the bag, it would take forever to restart. It was to the point that it was literally wearing me out to get the engine to turn over again. I always change the oil; clean or replace the spark plug and clean the air filter before the start of every season. I did some research online and found the carburetor could be causing the issue. Rather than remove and clean the carb, I decided to try an additive. I have to say this product exceeded my expectations. I pumped out what fuel was left in the mower and discarded it. I filled a 2 gallon gas container with fresh fuel and added an ounce of the Fast Fix. The engine appears to be running smoother and almost always restarts with one pull after the initial start up. I would recommend giving this a shot as an economical solution.

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.

I used it, didn’t see much improvement. I doubt I will get it again. Products like these are usually a better idea than it is in practical application.

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.

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

This is amazing stuff! Saved 2 mowers and a generator. We swear by it!

I don't write a lot of reviews, but it's worth it for this stuff. My snowblower carburetor was pretty clogged, to the point of hardly having any go power. Used one application and a couple uses later, it's now running like new! Def worth it!!

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
