I'm guessing those tanks have been sealed from when you filled them?
Gas goes bad primarily from absorbing water from the air, oxidation, and evaporation. Since the tanks were kept closed, the gas will last for years.
Gas cans that are used frequently need stabilizer because every time you pour a little to fill a lawnmower, fresh air gets in to replace the volume poured out.

Correct, they've been sealed since I filled them three weeks ago. Thanks for explaining a little more around how gas degrades.

I dont know anything about this but in (yes fictional) apocalypse novels the gas in car tanks always goes bad after several months.
