STA-BIL, Star Tron, Yamalube, K100, SeaFoam, Marvel Mystery Oil, Fuel/2 Stroke Oil Premix, and Untreated fuel compared for freshness, ability to protect metal from corrosion, and prevent rubber from hardening after 3 years. Subsequently, I tested a new batch of fuel for an additional 20 months. From start to finish, this review took over 5 years. I purchased all of the fuel stabilizers and the products used to review the stabilizers to ensure an unbiased review.

STA-BIL Brand Manager here. Thank you for the realistic testing. There have been many youtubers lately doing innacurate real life ratio water "demos" and the latest scam demo of removing ink from the bottom of soda cans which proves nothing in the real world. For those who use a fuel stabilizer reading this, with storage season coming up please go to the gas station and get fresh fuel in your gas can, not half a can of 3 month old fuel then mixed with fresh. COMPLETELY FRESH FUEL, then add the stabilizer. Then run all the old gas (month or more) out of your equipment and fill the tank full with the new fresh gas and run the engine for 10 minutes. Then you will be ready for storage.

39 years ago my father-in-law advised me to buy a new 1986 Bolens garden tractor, AND to use Sta-Bil in all my small engines. At the time he stated "This will last you for the rest of your life. I scoffed at him a bit, but kept using that stuff and took fairly good care of the tractor. Yesterday, I mowed the lawn again with that 39 year old Bolens!!! And tomorrow I'm treating it for the winter with Sta-Bil. It's running great after all this time, (although it's starting to nickel-dime me on replacement parts.) 1000 hours!!! 216 million revolutions! Never a fuel or carb issue; heck, it's only on its second gas filter. And I'm also treating the two 5-gallon gas cans when I fill them, the motorcycle, and the string trimmer. I sure miss my father-in-law. The longer he has been gone, the more and more I appreciate what he did for us. Thanks, Bob.

in response to sta-bil brand manager, i have used sta-bil for I'm sure 40 or 50 years, have never had a fuel failure, never even bothered with anything else.
