Location: Elk River, Minnesota | LOL...as I'd say directly to you as well... Take a flawed garage experiment over scientifically proven, tested, engineered designs created by multiple people...or better stated....TEAMS of people well versed in the science behind every step of the design and manufacturing processes including the fuels used, feel free. It's your motor, treat it how you want.
In the end, it doesn't matter what fuel you use given it is designed for your engine...MAINTENANCE is the key, and that is the bottom line.

I also spent a little more time reading a master's thesis about ethanol blends and aluminum corrosion. It's 100% scientific in process from beginning to end. Although the read is lengthy and very in-depth, it does highlight many things about ethanol that are important for everyone to understand as it pertains to the aluminum alloys being used today. It should also be noted that the aluminum used in the garage experiment may not even be close to the alloys used in the industry, and the whitish layer on the aluminum is always going to happen as aluminum naturally will oxidize in almost all natural environments. That oxidation layer is what helps protect the aluminum from more oxidization over time. It's no different in some ways to the blueing on a shotgun or rifle. Bluing is just another form of oxidation using a different chemical creating a different chemical reaction than water and iron making rust. Aluminum is no different.
