1. Diesel will last 20+ years with no special care whatsoever. Dad had an old 4020D that he stopped using in 1999. His rule for 40 years was, fill up when you finish using the tractor, even if it only takes a half a gallon to top it off. That tractor was not started again until Fall 2019. No ether, no gassy rag on air intake, just hot batteries and it barfed up several metric buttloads of black smoke then settled into 'ready to work' idling.
2. Gasoline (with corn squeezin's) from 2020 stored in plastic fuel cans *mostly* airtight runs just like new in small engines as of about a month ago when I mowed the grass last.
2a. Gasoline stored airtight in steel cans is completely indistinguishable from 'fresh' gasoline.
3. Those purple quart cans of mixed gas will last for >1yr in the fuel tank of a weedeater.
4. The same cans, partially used, will last from at least 2019 until last month or so when I put some in an old F.O.R.D. chainsaw I garbage picked. Unknown why that Jonsered 22" was sitting out by the trash barrel on pickup day but I did garbage pick it and it fired right up on ~3yr old ready-mixed gasoline from Walmart.
5. As long as gasoline smells even SORTA like gasoline, and is clean, it will fire up in a carbureted engine.
Conclusion: I'm wondering just how much of the additive/preservative market is hype promulgated by the manufacturers of such products.
