How long does it take for propane to go bad?

[Pro Drywall]

I seem to recall that gas and diesel will go bad around 5 months for gas and diesel is something like a year. What about propane stored in tanks?

True, propane doesn't go bad. ProDrywall - diesel will last 12 months and gas will start to go bad around 4-6 months.

If propane is stored in a sealed tank the you will have no issues.

Yep, all good for long time. Actually we have found 1lb tanks that are YEARS old and still work just fine.

I had some cans that were stored for a year and so far they work fine

Hey thanks everyone. It’s funny, I have propane tanks from LONG ago, and they still work. Just never thought about how long they actually last. Now we know!
