STA-BIL Fast Fix Small Engine Treatment, 8 oz 12-Pack

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.

Worked great for me. I had a lawnmower that sat for 3 years. Siphoned out the tank. Added fuel. applied less than an ounce to the pint of fuel in the gas tank. Let it sit for a day. Started fine. These are the Amazon products I used for this and other lawnmowers that didn't need this product.

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 is flat out amazing for 2 cycle small engines, works like advertised. 4 cycle isn't as good, if your engine hasn't ran in years, you'll still have to clean the carb, but it does help some. The 2 cycle oil for one is a lubricant and inhibits varnish buildup (especially a synthetic premium brand), and usually premium oil has a fuel stabilizer in it. Plus if you don't have a float bowl, there's not enough fuel for phase separation. I also use it in my mix for my ultrasonic cleaner when cleaning carbs. Overall a very good product, but understand it's limitations in this modern age of ethanal fuel.

I've used STA-BIL Fast Fix a few times now, and it works great to bring hesitant engines out of winter hibernation. Just today used it on a Stihl pole saw that sat all winter. The saw would start, but run rough and die on idling. Added a small amount of STA-BIL Fast Fix, ran it for a few minutes, and now it runs perfectly. I'll always keep some on hand, as it works for me!

STA-BIK Fast Fix Small Engine Treatment works fantastic. Everything from value for money to ease of use. I bought one bottle and used it in my gas leaf blower and my gas lawnmower. Both of them while running had the surging of the motor when it seems like the carborator is getting clogged. I followed the directions and let the lead blower and lawnmower run for 15 minutes and they both ran better after it cleaned it. I'm throughly impressed with this product by the good results I had. I plan on buying more bottles to have on hand for future use. It's a lot cheeper than Taking it to a small engine repair shop and having them charge you over $150.00 I've already experienced that and don't want to experience it again. I also will tell my family about the product so they can save money.

BLUF: It worked with a slight modification to the instructions. BLAB: The instructions say to just add it to the tank and let it run for 15 minutes. Didn’t quite work for my case. It improves slightly but still was stumbling and hunting. So I remove the line going to the carburetor and injected some of the fluid directly into the line. The machine started up on the first spin, stumbled once or twice as the raw Fast Fix got to the carb then it blew out dark exhaust for about 2 seconds and started running perfect. Sure beat a disassembly of my zero turn mower’s rear-end just to get to the carburetor.

this product seems to work well, but it wasn't the product I ordered. I ordered the gum out brand.

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!

Worked very well,very satisfied.

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
