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.
Review: keeps your small engines running longer. - good stuff and good price.

### ⭐⭐⭐⭐⭐ keeps your small engines running longer.
*by S***R on May 23, 2026*

good stuff and good price.

### ⭐⭐⭐⭐⭐ Best “value for money” fuel system cleaner on the market
*by C***. on May 17, 2026*

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.
