STA-BIL Fast Fix Small Engine Treatment, 4 oz – Treats 10 Gallons – Fixes Rough Running Engines, Carburetor & Fuel Injector Cleaner, Removes Water, for Lawn Mowers & Small Engines

Works Great, at first didn't believe all the reviews, I've bought 5 chainsaws from one season to the next. After each winter couldn't get them to start. Followed the instructions to flush and let sit for a few days. Every one started and ran great. Hands down, this is a remarkable product for cleaning out blocked fuel systems from sitting all winter would recommend it for all 2 cycle engines and use the stable blend for winter as well as anytime use to prevent fuel spoilage.

Used this in a Troy Built Garden Tiller, the tiller would stall and hard to crank until we use the Sta Bil Fast Fix, tiller now runs great and does not stall.

10/10 Excellent product, really helped me with my snapper snowblower that kept stalling over and over during a blizzard....I highly recommend this product. This is not a paid promotion. Thank you STABIL FAST FIX

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.

This stuff works. I added it to my four 5 gallon gas cans before filling them up. I’ve used 10 gallons of gas in my lawn tractor so far and can tell it likes it. I do annual maintenance before summer and check or change the spark plug so it performs the best it can. I have 508 hours on it and with this it seems like it idols smoother, which indicates it has helped in the carburetor since I haven’t had to remove it and clean it.

I used this on a 2002 Honda Shadow motorcycle that has sat for about 6 months. It wouldn't start or stay running unless I held the choke. After holding the choke for about 20 min to run this stuff through the carbs I let it sit for about an hour. I had to start it up again using the choke but after a few more minutes of trying to get the engine to rev it finally gave in. Now it's running great again. Definetly saved me from having to tear down the carb, I tried getting it going so many times over the past week before I gave in and bought this stuff.

I"ve used Stabil gas treaments for year but never this particular type. With gas the way it is, I decided to see how it might help my mower and also my older truck. My older push mower which admittedly doesn't get pampered and petted seems to love it. Either it's grateful to get anything special or this stuff really has helped. The first tank seemed a little smoother but by the second I could hear the difference and feel it with the smoother sound and seems more power. It's easy to mix and use and Stabil is a well known reputable company.

Works. Not as good as carb cleaner

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

Worked perfectly.

Great product. Snowblower was struggling to start then popping when running. Put in and ran for 15, then let stand for a few hours and started again. Completely running smooth. First video was loud running and popping noise. Not smooth. Then this is after use.

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!!

I was weary at first, but I added a small amount to each of my snowblower, lawn mower, and gas trimmer, and I can hear a subtle difference in the smoothness of the engine's run, especially my lawn mower. I maintain my seasonal tools with gas treatment and oil changes, so this is just an add-on, but I bought a second bottle because of how pleased I was.
