Review: Great product - 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.
Review: Pure Gold, Pun Intended - 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.

### ⭐⭐⭐⭐⭐ My Engine's New Best Friend—STA-BIL 360 is a Game Changer! ⛽💪
*by D***K on July 9, 2025*

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! 🙌🛠️
