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. Review: All good, long time user here - I have been using STA-BiL for almost 2 decades, I always put a little bit more to treat the gas, no issue with gas that I got in the fall, and using now in late spring. I usually don't use gas longer than 6 months — old gas go into my car. No issue with clogged carburetor in my snowblower, lawnmower, hedger and string trimer. i empty the tank as much as i can for the snowblower and don't fire it up till a year later. No rust in the gas tank either. Good insurance to have against needless repairs and tinkering. ## Features - Fuel System Cleaner - STA-BIL 360 Protection completely cleans the entire fuel system from fuel injectors to fuel pumps, and removes water, gum, and varnish to keep your fuel system free of corrosion - Fuel Stabilizer - Use STA-BIL 360 Protection to prevent fuel corrosion and keep ethanol-blended fuels fresh for up to 12 months, so your fuel system and engine stay healthy and ready for action! - MPG Booster - STA-BIL 360 Protection helps you get the most out of your fuel at every fill up, and increases your gas mileage and engine power with a clean and protected fuel system - Directions - Pour directly into fuel tank prior to fill up.

Will this product give me any benefit?** A: It will prolong the "Freshness of the gas either way " **Q: what is the difference between this product, Stable 22275 360 and Stable 22284 360? 22284 has less product and costs more.** A: Good question. If you go to the manufactures site, goldeagle dot com, you won't find the 22284 product, just the 22264 product. **Q: Can be this used in 2004 Lexus ES330, general gas not ethanol fuel.** A: Uh.. general gas for vehicle has ethanol. Only fuel you find without ethanol is on some boat gas station for boats and maybe some race track gas station. I doubt you are in either category. So yea, your fuel has ethanol and this will helps it if you don't drive it often. If you drive it and gas gets depleted in a week, then this doesnt do much. You maybe just want some fuel cleaner like the Chevron Bottle to keep your fuel injectors clean instead. **Q: Can this be used in the gas for a Mercury 90 outboard motor ?** A: Absolutely. It can be used on any gasoline engine. It works on non-ethanol and 2-cycle fuel as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pure Gold, Pun Intended *by M***W on May 15, 2025* Been using this stuff for years.

So in 2026 we’re fighting a losing battle with fuel system deposits and all kinds of issues with ethanol gasoline. “Top tier” fuel stations like shell and chevron help, but it’s impractical to go to top tier stations 100% of the time. That’s why I like this stuff so much. I always buy the largest bottle of this stuff, and I add 5oz on an empty tank to my truck, 4oz if I fill up on a 1/4 tank. That means the large 32oz bottle is good to fill my pickup trucks gas tank 6-8 times with this stuff. So for about $15, I get 6-8 tanks of gas worth of a strong PEA fuel system cleaner, that’s an incredible value. I just leave it in my trucks toolbox and always add the 4-5oz at the gas station before I fill up, it’s like muscle memory now. I personally prefer this fuel system cleaner procedure over the much more aggressive cleaners you empty an entire bottle of every oil change. This is a much more gradual (yet still effective) process that you add every fuel tank. This is a fantastic proactive maintenance item that I highly recommend. ## Frequently Bought Together - STA-BIL In-Season Protection Fuel System Treatment | Full Protection Fuel System Cleaner, Injector Cleaner, Increases MPG, Prevents Corrosion, 4 Fl.
