My strategy recently has been to buy some fresh ethanol-free mogas and use it to mix with whatever “stale” fuel that’s been sitting when I fuel the plane. The resulting 50/50 mix should be fresh enough overall.
Not advocating for that, just putting my procedure out there for discussion.
Yeah, I was thinking about doing that as well, or as MrMorden suggested, just dumping a few gallons of 100 LL as a octane booster - that would work.
On the other hand, I can use the old gas in my car so nothing really is lost - will make for a very happy car engine
