STA-BILIn-Season Protection Fuel System Treatment | Full Protection Fuel System Cleaner, Injector Cleaner, Increases MPG, Prevents Corrosion, 32 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 buy this every year before I put my yard equipment up for the winter. I put it in the unused fuel I have leftover as well. In the spring I can take my equipment out of storage and they start up without a hitch. The fuel I saved from last year still works like time hasn't pasted. I have also used this on my boat and it saved me from having to pump the old fuel out in the spring. It a cheap way to save money and your equipment. The bottle tells you how much to use. The spout makes it easy to pour and close up . I will always have this on hand. You just never know when you might need it.

Perfect Product that I've been using for years. Works every time, for every piece of equipment/motor, and seems to have never changed ingredients. Still as strong and useful as it was years and years ago when I came across it the first time. Great quality product, easy to use, but most importantly, IT WORKS!

used it for the lawn mower and snow blower

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, use this product!

If you use small equipment like generators, chainsaws and so on please use this every time you fuel.

I worship at the alter of Sta-Bil. In 25 years, it's never let me down; and HATE cleaning carburetor jets. Now, in those instances where I failed to use Sta-Bil, did I mention how much I HATE cleaning carburetor jets?

Excellent product
