    What octane gasoline do you use in your 4 cycle engines?

    87 in everything. If higher octane does anything, I guess I don't know what I'm missing.

    According to the Dixie Manual, the Generac motors thrives best with 89...I run only 89 in that mower and the Ferris Walkbehind...87 for the trimmers with oil mix

    Was running 87 in the 23 horse and was getting too much dieseling at shut down, went to 89 octane and it seems to be much better. Once the heat backs off a bit it'll be back to 87 though.
