Fill several 5 gallon jugs with gas as well, and add Stabil so it lasts a few months through the coming fuel shortages.
Better alternative than Stabil is "Sea Foam". Problem with Stabil is, it creates a 'seal' over the fuel, but once disturbed/moved, the seal is broken and does not reseal. And then its useless. So HUGE fuel storage units and devices that are not moved, fine. Move the lawnmower mid winter, NOT fine. Sea Foam is a diff. approach in that it mixes with the fuel. So its not effected by any sealing method.
I had a bitch of a time with a touchy Honda power washer. Once on Sea Foam, no more problems. A guy I know who repairs engines as his business, 100% concurs.
