Ethanol in Fuel

Almost everyone has pretty strong opinions about ethanol, so we tested the myth, which states that ethanol will eat through seals and metal alike given enough time.

As it turns out, the myth is true, ethanol on its own is not corrosive but if it is mixed with water it can eat through rubber and metal alike, altough very slowly, it would take years to notice any negative effects in the real world. The chances of having at least a tiny amount of water in your fuel tank is pretty much 100%, which means for all intents and purposes, ethanol will indeed eat your components from the inside out, altough be it extremely slowly.
