Review: Great product! - 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.

## Questions & Answers

**Q: 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?**
A: 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!

**Q: do you pour it unmixed into the small engine?**
A: 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

**Q: when will the stock come??**
A: Asap

**Q: Do I pore it in the gas tank on my rovan Baja gas rc or mix it with gas just asking**
A: Either would work but I just poured it in the tank and it worked well

### ⭐⭐⭐⭐⭐ Sta-Bil fast fix
*by M***O on June 8, 2026*

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.
