I have a gravely zero turn mower with a Kawasaki FX481V motor. This is a 15.5hp twin cylinder motor with an oil filter. So the mowers manual only mentions changing the hydro fluid and doesn't say anything about the motor oil, but I notice on the hour meter display it tells you to change it every 50, but the manual for the Kawasaki motor says oil every 100 and filter every 200hrs. I went ahead and followed what Kawasaki says. I'm going to use one of my Polaris labs Uoa kits that I bought and send in a sample, but what do you guys think? The oil is dark brown at the moment and I have 90hrs on the mower. I use delo 400 15w40. I also changed the oil after the first 8hrs like it said in the Kawasaki manual. Should I just start changing it every 50 from now on?
