[E15 gasoline] Killbox for a reason
Engineer fag here. This shit sucks. Will shorten the life of many components, degrades rubber fuel lines not designed for it, and is totally a killer of small engines like weed eaters and lawn mowers that sit around a bunch. The alcohol absorbs and retains water which promotes corrosion on top of that. I'll put up with it short-term if it helps with the China situation.
Still trust the plan 100% but setbacks do happen.
