Worked great, saved me hundreds.
Size: 8 Fl Oz (Pack of 1)
I've had issues with the carburetor on my 2003 Honda ATV for years. It has needed cleaned regularly to stay running, and one repair shop wanted over $400 to replace the carburetor. One treatment with STA-BIL and it's running smooth again. Very impressive.

Great for 2 cycle, meh for 4 cycle.
Size: 8 Fl Oz (Pack of 1)
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.

It works well.
Size: 8 Fl Oz (Pack of 1)
Great product that delivers on what it says it does. This won’t fix a mechanical problem or damaged component, but it will fix a stuck float, varnished tank, gummed up jet, or partially blocked emulsion tube.

It Works
Size: 8 Fl Oz (Pack of 2)
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. Works great.

Great product
Size: 4 Fl Oz (Pack of 1)
Used this stabil in my rider after first start of the season. Machine running rough and uneven. Drained old fuel and added it. Within 15 minutes at full throttle it began to run normal. No back fires and engine back to normal. There will always be a bottle of this in my garage.
