I use the bottled gasoline/oil mix for my leaf blower and chainsaw, it's convenient, but costly per gallon. Sometimes it's on sale.

I mix my own gasoline/oil mix for my 30 years old Lawnboy 2cyl. All I do at the end of the season is run the fuel out and don't park them next to the garage doors where condensation can occur in the tanks.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats. H. L. Mencken
