I run super (92/93) in all my small engine and off road stuff (even my mower), I know it doesn't need it but I have some friends in the petroleum business that were telling me about the difference in additive packages between grades of fuel and that it is a factor between regular and super unleaded. Since its not like the expense of filling up the truck twice a week it really isn't that much more expensive for the better additive package. The extra octane is just a bonus.
