I've got a new Kubota M8540 tractor and was unsure which engine oil to use so I submitted a question using the kubota web site.
I received a call today from a service representative at Kubota headquarters in Atlanta, GA (I'm in Tennessee). I was told that I should use 10W-30 engine oil which has the CE or CF API rating. I was told not to use 15W-40. I was told that I do not need to use Kubota brand oil, I would not void my warranty by using another oil as long as it had the correct weight and API rating.
My operators manual says 10W-30 or 10W-40 with the CD, CE, or CF ratings. What is interesting is that I contacted two local kubota dealers and they both said to use 15W-40 which contradicts the operators manual and the advice from kubota headquarters.
So I went today and bought 3 gallons of Kubota 10W-30 engine oil, it has the proper API CF rating, actually it goes up to CI-4 I believe.
I was also told by Kubota headquarters not to use synthetic oil in the new motor, it had something to do with the rings. Kubota headquarters did not see much value in using synthetic oil but said if I really wanted to use it I should wait until the engine has 150 to 200 hours on it. I think I'll just stay with the standard oils which apparently are very good quality these days.
I have the hydraulic shuttle wet clutch transmission on my tractor and was told by kubota headquarters that I should use the Kubota SUDT fluid for the transmission/hydraulic fluid.
Finally Kubota headquarters also said I should use heavy weight 80W-90 gear oil in the front axle instead of the SUDT fluid. He gave me a tip on changing the front axle fluid, he said to open the drain holes at each of the outer hub gear assemblies and drain the fluid and then to use the front end loader to lift the front end a little and then to push down on the tire/wheel to tilt the axle to get more fluid to drain out.
