Porkchop I think you made a wise decision. The engine with the proper care will give you hrs of great service. I did read on the Kohler site though to run non syn oil for 50 hrs or more to let the rings seat good before running syn oil. Just go to Kohlers web site and read the Maintenance suggestions. I'm going with straight Pennzoil 10-30 in mine for now.
I am going to treat the mower like my snapper when it was new. Just use what the recommended oil is in the manual and do what they want until the warrenty runs out. On my snapper I used kohler oil and kohler oil filters until the warranty ran out. After the Warranty I used kohler oil but oil filters from advance auto. I can get about three for the price of one kohler filter. Engine runs like a champ to this day!! I like kohler oil it's fine and I change it way before it gets black. I change it to early probably. Wish my Snapper had an hour meter. Pennzoil is great stuff:thumbsup:. I run Pennzoil platinum in my truck!! Take care TnHusky!
