In-Season Protection Fuel System Treatment, 32 oz – Treats 160 Gallons – Fuel System Cleaner & Injector Cleaner, Improves MPG & Engine Performance, Prevents Corrosion & Ethanol Damage

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.

This product is very good. A friend of mine who knows a lot about aviation told me about the issues they were having with ethanol in their fuels and that the same is true with today's E10 in autos. Since I have an older vehicle, the ECU is not programmed for running ethanol blended fuels, 360 performance helps combat this by doing two things. 1, it helps counter the corrosive properties of the alcohol in the fuel lines and injector o rings. 2, it alters the ethanol chemically to behave more like 100% gasoline. (I wish I knew how it does this.) My car runs smoother and starts better when hot, it use to not do this. I keep my car in top nick, and tuned up on a regular basis, so there is no neglect outside of regular issues you might have with a daily driver.. These properties are essential for lawn equipment, dirt bikes, motorcycles, two stroke engines and earlier obd I & II vehicles. The E10 blends tend to spoil quickly and this will help that as well. I wish I had this stuff 10 years ago. In CA, they started a 3% blend in 2003, then went to a 5% in 2005, then a 7% blend in 2007 to a 10% E10 in 2010. Newer cars can handle a 15% but none earlier than 2007, so the E10 mandate is a compromise. The only way to buy ethanol free fuel is to buy race gas at a very high price point, the Stabil 360 Performance is an economical additive to combat the ethanol properties. I don't know if this affects the octane rating after adding. I really started to think about this topic: Out of every 10 gallons of fuel i put into my car, 1 gallon is ethanol. No wonder my car was running like doo doo!

I was tired of my small engines sputtering and stalling after sitting idle for a season. That's when I tried STA-BIL 360 Protection Ethanol Treatment & Fuel Stabilizer. After adding it to my fuel, I noticed smoother starts and better throttle response. My mower, snowblower, and even my boat engine ran like new. It's like giving my equipment a fresh start every time. Plus, it keeps fuel fresh for up to 12 months, so I don't have to worry about old gas causing problems. If you're looking to protect your engines and improve performance, STA-BIL 360 is a must-have! 🙌🛠️

good

I have used this product in my car for years. Works great. Also, prefer adding my own additive. That way I know the additive is in there.

Well it must work, no issues with my lawn mowers and pressure washers. Happy with the price, Yes I use this much in a 9 month summer long mowing season on my lawn jobs.

Excellent Product as advertised.

We use in one of our vehicles, our generator and all our lawn items with motors. It does the job well

Seams to work great in all gasoline engines

Necessary with modern fuel especially with little used engines!

Good value

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.

Very good. It does what it suppose to do. I believe this is the best on the market. Easy to use and instructions clear to understand.
