The OP didn't mention if he needed a large amount but for small engines like my snow blower and yard equipment I use TruFuel like Wolfeboro Baja mentioned. It's more expensive than pump gas so I use it toward the end of the season so I don't have to stabilize or run the motor dry. I just switched to it this past weekend in my lawn mower but I use it exclusively in my blower and chain saw. Home Depot has it:
