I have a Kubota 2620 with a front end loader. I'm due for my 250 hour THF change. Has anyone used the Schaeffer's Simplex Supreme oil in their tractors, and what were the results? I have considered the dealer sourced Kubota Super UDT2 and the Schaeffers. I'm just looking for a little feedback on anyone that has used this oil before. I know, I could use any THF oil that can meet the specs, but I have narrowed it down to these two. And I can't source Chevron. Not looking for "I use this or that" response, just responses on the 2 oils that were mentioned. Feedback anyone?
