How many years do I have to use E30 to E50 in bone stock vehicles before you realize that the engine isn't going to get damaged?
Evidently 9.6 years of E50 in a 1992, 8 years of E30 in a 1995, and 1 year of E30 in a 2000 model year isn't enough to convince you.
I had a beautiful 1966 Mercury Comet, whose carb got slightly plugged with a black slime that was once fuel hose due to the remarkable dissolving effects of ethanol. An overly lean condition resulted in a very damaged engine. I discovered that many other people had similar issues, sometimes from hoses and gaskets dissolving, sometimes from the resins in certain fiberglass fuel tanks.
When I lived in Seattle, the ethanol corroded my aluminum weed eater engine, completely destroying it. I subsequently learned that the hygroscopic nature of ethanol makes it absorb water out of the air, and when it does so, it becomes even more corrosive than it already is. I'm glad I don't own a boat.
When I lived in North Idaho, ethanol damaged my chainsaw carburetor. The saw shop had plenty of carbs in stock, because they started ordering them by the case after the ethanol went into the fuel.
You are right about one thing: your experience isn't enough to convince me.
