Use your old ( slightly used )&nbsp\\;Harley oil in your lawn mower, It's better than any oil you can buy at tha lawn and garden store.

 

Gee, in my 4 cycle Toro I just use regular 10w30 motor oil bought from anywhere. Of course reusing your old Harley oil is ultimate recycling, I guess.

 

A lot of the engine builders I know always reccommend low mileage oil changes.New motors during breakin are in the wear-in stage.It is still up to you Good Luck&nbsp\\;
