Can't really stockpile gas. Even after treatment with Sta-Bil, it gets gummy and useless after a year or so.
I've put gas in one of my cars more than a year ago, as it's a project (1989 BMW 320i coupe) waiting for spare cash to burn, I've started it the other day (using cables) and it ran fine, so the gas must still be OK.
Yep. I have had cars left for even a couple of years and no problem with the gasoline.
I think it is gasoil what degradates more quickly.
