Think about it...if you have to add something to your fuel to make it safer/better for your engine WHY?! there's enough ethanol free stations it's not hard to plan your fill ups to use them. If you ask me, it's not any more expensive if you simply take into account additives and fuel consumption, not including mechanic bills. Your engine will also make more power and be more fuel efficient on ethanol free. No different than race cars, as you go higher in ethanol content (E85 then methanol) you have to use more fuel and have higher maintenance. If your engine uses the same amount of fuel it's even worse because you're essentiallt running your engine lean, which leads to most major engine failures due to extra heat it causes. Plenty of science behind it.

But yeah the pure gas website makes it super easy to find and use for those that trailer especially
