STA-BIL (22275) 360 Protection Treatment And Fuel Stabilizer Corrosion-Prevents Ethanol Damage, 32 fl. oz | Treats 160 gallons. Cleans fuel systems and injectors while helping protect against corrosion and ethanol damage.

I have been using it in BSIV car for a year with every tank fill. It has negated every ethanol related problem. After using this, no rust , No loss of power, no hesitation in my car. I am also getting a milahe of 14kmpl in city compared to 12KMPl when I was not using this.

Great product , all Indian petrol old car owners should use this , I recommend to use it every full tank , I started pouring Jio petrol with this product and got increase in my mileage from 12 - 13.2 , 10% increase , mostly covered the cost of this product and also greatly increased the life of my petrol tank and all internal components.

Works well, engine feels smoother. Hopefully with get the bike thru the E20 stuff.

Item seems to be good just started using delivery very much before time

Excellent for Superbikes that are very sensitive to fuel with Ethanol.

Used it on my maruti ciaz petrol engine .. was happy to see the performance and mileage was improved significantly

Received item perfectly packed and without any damage. Just used for one refuel. I think it's working on the mileage front. Long term review not possible now.

Works well. Go for it.

Seams to work great in all gasoline engines

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.

Just to clarify, the 4oz bottle is also the 360 line with the vapor technology. The picture doesn't make that clear but Sta-Bil has changed their line up. I purchased a box and can verify that I received the new 360 packaging. The 4oz bottle will treat 20 gallons which is why I purchased it. The cost per ounce is probably cheaper if you get the bigger bottles but for the convenience of one bottle per vehicle per month was just too much to pass up.

I am glad Sta-bil offers this product for small gas engines. I use it in my lawnmower and classic VW beetle. Too bad we have to buy a product to remove Ethanol from gasoline. Fortunately, this product is available when you cannot find Ethanol free gas. Don't confuse this Sat-bil product when their other product which is for using in gasoline in storage.

This is hands down the best value for money fuel system cleaner on the market. 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.
