Same here. I'm going to expand on this quickly. Ethanol combines easily with water, unlike gasoline; this is true of even your standard run of the mill 90/10

Same here. I'm going to expand on this quickly. Ethanol combines easily with water, unlike gasoline; this is true of even your standard run of the mill 90/10 mix of gas/ethanol not just the E85. So you end up putting fuel into your engine that contains higher volumes of water that is released into the engine internals. This causes rust and gums up carburetors. This is especially hard on small engines; lawn mowers, weed trimmers, and motorcycles. It's not good for your cars either and this has zero relation to octane.
