Years ago I was told by someone who either worked on something for me or sold me something not to run the engine dry and leave it all winter. The theory was any rubber gaskets, etc can dry out and crack. For years I've bought mid grade pumped gas for all small engines and at storage the canned fuel from the store. Everythings starts up for me as expected when needed. After 7 or 8 years if I'm losing a little performance from something I wouldn't notice it anyway most likely. Also, I never buy "no name" gas for anything, it's always Shell, Mobil or those brands for me. Son bought a used Cadillac from a friend and when he had it at a dealership they told him never put Cumberland Farms gas in it. Specifically mentioned "Cumby's." Had a few definite issues resolved making the switch from "cheaper" gas over to Shell. Yeah it's all the same stuff out of the ground it's the additives they add making it their own.
