Wanna know something about petrol going off?

It goes “off” as in out of spec. Not unusable. Not even *bad*.

The trout is on the same tank I last filled it with in June 2025. It runs fine.

I had another Falcon that sat from 2001 to 2009. Ran fine.

Maybe less power, or lower mpg. Couldn’t tell.

A really finely tuned engine control computer might complain, might throw codes. It might be really noticeable on a high compression or high performance engine.

But the mad max wasteland will be fine.

@NanoRaptor It’s wonderful if you can get ethanol-free fuel, but the evil additive is mostly mandated in Canada and eventually turns to crud in your engine’s plumbing.

For my small engines I get premium grade ethanol-free at the nearest Rez and even then make sure I run everything at least twice a year.
