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.
