This whole synopsis of which hydraulic oil works best has been queried over and over. It is interesting to read the differing opinions and experiences, and certainly thought provoking. The posts from ones "who are in the know" always cause me to ponder. Am I doing the right thing with my little orange friend?
But, all that being said...since my tractor use is not demanding on this little 2004 BX23D, sticking with the SUDT2 doesn't seem all that burdensome. Now that I've gotten the hydraulic fluid leak stopped, the use of more fluid comes mainly at the time to change the fluid...lots of hours of use. Cost is always a part of my shopping ventures, but spending a bit more on Kubota fluid somehow doesn't cause my spidey sense to activate! Must be something wrong with me or the Kubota Kool Aid has taken a firm grip on my reasoning.
I only hope this little tractor somehow appreciates the TLC it gets and will respond appropriately when ask to do its menial tasks. As always, time will tell.

PS After posts to discuss engine oil, I did change to Rotella T6 diesel so maybe an old dog can be taught new tricks.
