Hey fellow oil guy`s!! Well yesterday I broke down and bought us a new Toro personal pace,electric start,self propelled,22" mower from Home Depot.Cut the grass yesterday,and it really does a nice job.And I like the rear propel better than front.Says to use 30 weight detergent oil in it,until 5 hrs,then I`ll go with my GC.Although it says in the manual that 5W-30 synthetic is good for all temps. Do you guy`s think maybe I would be better off using PP in it instead?
