I've been told that it all stores the same but I wouldn't bank on that.Also try to avoid gas containing ethanol, as I've read that gas will go bad much quicker than non-ethanol gas.
My question is, will 89 Octane last longer than 87? I generally only store gas for about 1 year using sta-bil, but have always wondered if higher octane would be better to store?
I wouldn't.Can you keep gas or diesel in those storage tanks that people put water...they look like large white plastic squares with a metal grid on the outside. ???
Personal experience?Don't use Sta-Bil for "long-term" storage. It's fine for over-the-winter kind of storage, though.
Use Pri-G for long-term storage.
Some people whine about the cost of Pri-G, but compared to the value of the gas today and it greatly increased value after SHTF, it is very cheap.
