Any good reputable oil is fine. The JD oil is formulated for smaller engines tho AND you are going to be getting a JD Oil Filter (you should ALWAYS run a JD filter) and the JD oil isn't any more expensive than any other.
Wow, pretty snarky response there xcopterdoc. I blame my self for not providing the tougher questions to challange your gator knowledge but I hope you realize how valuable the information you share is to the less experienced gator owners or maybe that crappy winter you're going through is starting to wear you down. Hang in there, I'm sure I'll come up with another challange for you. Or is it that Ginn is leaving the Panthers to go to the Cardinals got you all spun up??
maybe this will help; I installed a new coolant temp switch a few weeks ago, then when I was installing the new oil pressure switch I leaned up and snapped that electrical nipple off the coolant switch. Funny how one little thing will ruin your day
Mike listen to Deeresales 101............I myself work in the service department for a JD dealer for the last 16 years and get asked that very same question at least 3-4 times a week. The only JD oil I do push is the JD HyGuard (hydraulic oil) because I know first hand what other oils can and will do to 30-40,000.00 trannys. Engine oil is critical but as long as you use a good quality oil you should be fine.....but please don't skimp on your filters....the JD filters are made to different standards than others. And FYI..........good question.
