Most of the name brand mix oils also contain a fuel stabilizer (at least all of the ones I have ever used do). I certainly agree that E0 fuel is he way to go, if you can get it. I have no hard evidence, but I suspect that has a far larger effect on engine and carb longevity than whether someone uses a stabilizer or not. The shelf life of E0 is longer than E10 or E15 gas. I add stabilizer in every 5 gallon can of E0 I buy for my small engines, mainly because I'm never sure how quickly I will use it up. I only mix a gallon at a time of fuel for my 2 cycle engines. Yes, the stabilizer in the mix oil is probably redundant. On the other hand, the only 2 cycle engine I've had fuel/mix-related problem with is the brush saw I lent to a friend who straight-gassed it.Stabilizer in my OPE with Efree gas is right here in bottle.
Never added any extra BS outside source in OPE. Never a issue but I still say that is because of Efree.

To be fair, I'm not exactly sure how many engines my dad lost with Stabil. He was responsible for maintaining roughly 75 acres spreas across 5 different campuses at the time. Most of his equipment was either diesel or 2 stroke. I know he lost the engines on at least 5 snow blowers, but I'm not sure what else. Listening to him rant more about it wasn't going to replace the engines on my atv, Dixie chopper, tillers, or string trimmer so I just let it go.I'm not pretending it's anything great, or that it lives up to its marketing hype. But the reality is that any product with a 100% failure rate would not be at the top of the market, in terms of sales, especially after 20+ years on the shelves.
Stabil may be crap, I certainly don't use it anymore. But I have to question your story, just the same. No one is losing "entire fleets of equipment", or having every engine into which they install it fail, without some other undisclosed factors in the mix.
And I have used Stabil in the past, many times in my own portable generators, with no issues. I switched to StarTron several years ago, because it's supposed to be better, but I've honestly never had any issue with either.
Actually, the Stihl orange bottle is the cheaper stuff. They claim the gray bottle is their “high end” 2 cycle oil.Echo Red Armor (red dyed, not the base Echo oil that is blue) and the Stihl HP (orange Bottle, not the cheaper grey bottle) both contain your fuel stabilizer in the oil.
