STA-BIL Marine Tune-Up Fuel Treatment – Cleans Carburetors and Injectors – Fixes Rough Running Engines – Eliminates Water – Treats up to 20 Gallons – 8 oz. (22313), Blue, 8oz

Left 10% ethanol gas in my 3500 watt inverter and forgot about it. After I got it started, it was suging and alsmost unusable even with fresh gas. Drained all the gas and used a measuring cup to get the fuel/additive ratio right and let the generator run wiuth a 1000 watt work light. AFter about 15 minutes, the surging stopped and engine smoothed out. Happened faster than I expected. Taught me a lesson about gas decomposition. Promised the genny I learned a lesson to use stabilizer. Easier than doing a carb rebuild.

My 3.0 MerCruiser stern drive was hard starting and would not hold at idle and ran really rough under load. I put 2 cans of S*Foam Marine through the tank and replaced the fuel filter and the spark plugs. With only a slight improvement I decided to bring it to my dealer. They replaced the distributer cap, rotor and plug wires and sent me on my way. The idle was good, but under load (headway speed) it ran really rough. Brought it back and they swapped out the carburetor and lake tested it. Back at home it ran great for a one-hour ride. A week later I tried to start it and the idle was bad again (engine shaking, erratic RPM). Almost dragged it back to the dealer but thought I would try this first. Per instructions I added this to about 15 gallons already in the boat and then topped it off with 5 gallons of fresh gas. Let it idle at about 1500 RPMs for 15 minutes and WOW, it's purring like a kitten. Next time, this will be my first resort!

I used the whole bottle in 1/2 tank of questionable gasoline from used boat from dealership, with no idea what mixture of gas water and particulates was in the gas tank in this 12 year old boat.The dealer started up the boat, and it was taking a minute to get the idle going. He mentioned that the gas was a few months old, but I am guessing that is was more like 6 months old. This is the TKS engine, self priming. I think some water / condensate was in the tank. Before taking out to first trip, I added bottle and 5 gallons fresh gas. That trip to the lake, I still has some issues getting it to start easily. Ran OK, not great that day, went home, changed cap and rotor and wires. Next trip, 1 week later, the 3.0L started great, ran great, I am not sure if it took some hours to fully mix and interact with the old gas, neutralize the water, and perform it's reactions, before it made existing gas more combustible, but that is what it seemed like to me.

Keeping my fuel fresh

Sta-bill really knows what they are doing. The color of this product will enchant you. You will lose yourself for hours in the depth of its blueness. Spilling your deepest darkest secret before realizing that this product just doesn't care about all that. It's got a job to do and you spilling your tea to it isn't getting that job done. Once you break it's hypnotic hold over you, it's simple enough to use. Dump a few ounces in your gas tank, run for 15 minutes and feel better about yourself because your didn't bust up your knuckles pulling a carburetor off. It's that simple. It reassuringly whispers to you "Don't worry buddy, I got you" and you just take it's word for it. You'll think your engine runs better, you didn't have to clean a carburetor and you can peacock down the dock knowing that you have some arcane magic that no one else knows of. Does it work? F@$# if I know, but I sleep better at night after using it.

Have a 1972 25hp evinrude with WOT problems. Prime the bulb and it would run perfect. Also cleaned and soaked the carb. New fuel line from the carb to the tank, new OMC fuel pump. And still had this problem. I decided I would add this to my tank maybe something got caught in my carb or something somewhere. Lo and behold motor runs perfect without having to prime the bulb. This saved me a bunch of headache.

These days, I need a gasoline supply for my generators for when the power goes off for any period of time. I treat my gasoline supply with this stuff and I know that I can count on my gasoline being good when I need it.

Product arrived on time and well packaged. I have used and continue to use this along with some other products to help clean and keep clean carburetors that have been damaged by ethanol gasoline. I was able to clean up and restore a Honda generator to properly running condition after I left some ethanol fuel in its tank for too long. OBVIOUSLY, EVERY SITUATION IS DIFFERENT AND I CANNO GUARANTEE SUCCESS. I can say that this has worked for me in three separate small engine cases. You may need to use it over time and in fairly heavy applications, but it can work. Have bought a number of times and I always keep this product on the shelf for use as needed.
