What? First of all, ethanol is not acidic, it’s actually slightly basic with a ph of 7.3. Second, a lot of places in the world allow up to 15% ethanol in normal gas, so all car manufacturers make their fuel system ethanol compatible. You won’t gum up a modern fuel pump with E85.

Yes a high ethanol content can cause the oil to break down quicker if a lot of it gets in the oil from your engine being worn, but on a healthy engine with a good seal on the rings you should be absolutely fine with a quality synthetic and the manufacturer’s recommended change interval. Dexos is pure 1000% GM marketing bullshit. It’s just another excuse to deny people warranty claims for using a non-approved oil(read: no license fee to them).

Running E85 is such a common performance mod these days that IF there was a big problem with it you’d see it all over the place With most modern engines being turbo DI everything from a Civic to a 911 turbo has flex fuel kits available.
