My dealer (back in 2009) said any premium UTF should be OK. I have a gear transmission; maybe hydrostat models are more picky? I think the key is to be sure the oil is rated for wet brakes especially because DKs also have wet PTO and 4WD clutches. Multi viscosity is a good thing too. I wouldn't use the cheap 303 stuff at Tractor Supply but their Premium UTF should be fine. By the way, as I recall, there is much more information on the actual containers than on the web site. When I last changed mine, I found two pails Spirax at a local Walmart but haven't seen it there since.
