Second on the premium and Pri-G.
Also, set up a regular quarterly rotation schedule and rotate the fuel into your vehicle. I use 5-gal cans so this is easy to do. Dump the fuel into your car, drive down to the hardware store, get Pri-G, then over to the gas station to re-fill and back to storage.
Also, both Stabil and Pri-G are essentially non-storable once opened, so be sure to purchase only enough to handle your current rotation. You don’t need to store it; if the gas stations are closed then there’s no point.
