STA-BIL In-Season Protection Fuel System Treatment | Full Protection Fuel System Cleaner, Injector Cleaner, Increases MPG, Prevents Corrosion, 10 Fl. Oz.

Been using this stuff for years. While you may be tempted to think it is snake oil, my fuel system is squeaky clean, I have virtually no carbon fouling, no corrosion and I am still running on the original fuel pump and injectors in my Stage 1, 25 year old Jetta VR6 and have zero fuel leaks.Fuel filters last longer and it takes much longer for the fuel to start losing octane. Helps maximize power and fuel economy. Noticed a difference to both when I started using the fuel treatment about a decade ago. I also use it in my motorcycles, garden equipment and my 2 stroke powered sport plane, where I also noticed a reduction in carbon fouling, increase in power and reduced fuel burn rate.Sta-Bil + fully synthetic 2 stroke oil is a power combo for getting the most out of any 2 stroke motor. Worries about fouling and seizing become a thing of the past. Longevity goes up dramatically. There is a noticeable increase in power. I calculated that my 65HP motor on my plane makes around 75HP at takeoff power with this combo. That's a 15% increase over standard oil and no Sta-Bil, nothing to scoff at.I have verified multiple times it does indeed keep fuel good for a year. I don't use the Storage version anymore because the in season is good enough for me since I live in the desert and don't need the extra corrosion inhibitors. But if you live somewhere humid and, especially if you live near the ocean, you should use the Storage version for anything that isn't going to run for more than 3 months.Keep in mind the storage product doesn't just protect the fuel system. It also helps to protect your cylinders, valves, rings and exhaust system internally by depositing persistent corrosion inhibitors and has way more of the stuff than the in season.This is why you always want to drive the vehicle a bit after you put the treatment in, before you put it in storage. Plugging the intake and exhaust will help the corrosion inhibitors persist longer.Best of all, Sta-bil products are very affordable.

I have used this product for years. I add it to every gallon of gas that goes in our backup generators. This product helped us get 14000 hours out of a small 3500 WATT generator. Other mechanical parts failed on the generator before the commonly occurring carburetor and fuel line problems that plague gas powered small engines. In my experience this product easily adds a couple THOUSAND hours to a well maintained gas powered small engine.If you want it to last, sue this product!

I use this for my scooter, and during the winter time when you don't use it as much it sure gives you the assurance that you'll be able to jump on and go whenever you want to

used it for the lawn mower and snow blower

I keep it in my truck just because it has a 36 gallon tank and doesn’t see daily use. It’s cheap insurance against fuel issues. From all the tests I’ve seen, the stuff does what it’s supposed to do.

When I'm going to be away, I always put this in all my cars gas tanks. Since doing that, I've never had injector issues like I've had in the past. If you're not going to use for car for an extended period of time, you need this in the gas.

I used this with all my lawn machines 4-stroke and 2-stroke engines. The fuel stays fresh for months and i no longer have issues with carbs.

Brought back a stuck up carb on a generator. Firm believer now.
