Sometimes we have those little epiphanies in the shower.. sometimes they come from other places. This is a home for those epiphanies.

Diesel has roughly ~double the shelf life as "normal" gas, so 6-12mo instead of 3-6. It doesn't just immediately go bad, but loses its energy slowly and burns less cleanly, so it could cause engine issues, but that's not super likely unless you've been storing it for a looong time.
