STA-BIL Fast Fix Small Engine Treatment, 8 oz

Mower was having trouble re-starting after a stop, and then eventually wouldn't start at all. I didn't want to completely pull apart the carburetor to clean it so I gave this product a try and it worked like a charm. I just poured a small amount into my mostly full gas tank, let it sit for a few minutes and did some soft pulls to circulate the cleaner thru the fuel system - and it eventually started right up. The cleaning performance seems to be very good because I've been having these issues for a while which makes routine mowing a pain but now the mower starts right up every pull and runs strong with no stalling. Will be using it in my weed trimmer as well to keep the fuel system gunk free. The bottle size is perfect since it treats 20 gallons of fuel and you only need to use it periodically for maintenance. Great value for the money.

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.

I have lots garden tools that runs on gas, I follow maintenance guideline and everything works as it should but some are pretty old and runs little rough even after tune up. Figure this treatment might help making some of the rough running equipment run better and it sure did. my edge trimmer alwyas splatters when I 1st started and idles Hunts a bit until it gets hot, after using this treatment, it ran smoother and starts quicker. also added to my mower and it did the same. My chainsaw which I use rarely and always hard to start and after running a while, it will die and hae to wait a while to get it restart, after adding this to it, it amde a big difference in starting and have not stalled out since the treatment. Will be using this prior to winter storage on all my equipment, two or 4 cycles.....

Git my Generac Generator running like new after the unleaded gas went bad after a year of sitting.

I have a 2003 Yard Machines B&S 6.75OHV that I use as a Winter Rye mower and turfing the Summer Bermuda grass down. I didn't do the Winter lawn this year, so the mower sat. I thought I should start it with some fresh gas....it disagreed. I bought the STA-BIL Fast Fix (I depend on STA-BIL regularly for all gas), I poured a little into the tank on the mower and primed enough times to flood for a few days in a row. I pulled the carb after that and wish I didn't, as I tore the gasket off for the air intake to carb. To my surprise, the carb was totally cleaned up, not jet clog, gas tank too. I have sprayed carb cleaner in the carb and get it to start for a moment. I have new gaskets now. Now the pull bar cable retainer on the handle (plasic cable retainer) broke. Next, vice grips w foam. This stuff works great. I have 25cc Ryobi blower, trimmer that are 10 years old or more. I added an ounce per gallon to the can, and a little dribble in the tank filled. They started running better when warmed up. I used to use 40:1 2 cycle mix, now 50:1 as thats what the engines say on them. It probably saved me a carb rebuild/replace on those. I'm going to keep using this until it's gone. Great for the money. Easy to use.

I was a huge sceptic, but definitely happy with this. Have a tractor that was running really rough which surprised me. Black smoke, poor power, etc. Put in an ounce in the gas tank and topped it off with brand new gas. Less than 15 minutes later it was running like brand new. Second test was the push mower. It was running a little rough and surging really bad. Put this in the tank with more new gas and in no time all was good. Both had been used this season, and I suspect the gas last time around was not good. So far this really did what it said it would.

This STA-BIL Fast Fix treatment is a handy addition to my small-engine maintenance supplies. It’s easy to use and has helped keep my equipment running smoothly, especially on engines that sit for a while between uses. I like that it’s designed to clean the fuel system while helping with overall engine performance. A simple product to keep on hand for routine small-engine maintenance.

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.

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

Had my snow blower repaired but would not start or even turn over when it got cold. Gummed up carb. Put this in the tank and a week later it started on the first pull. Awesome product. Would of never believed the hype but it actually works great.
