Back in 2018, when I had the analysis of this thread done, I refilled with Travelers again. When the next change came along in 2022 the next analysis was on par for the hours compared to the previous analysis, the copper level had not decreased, which is notable. So by this point, I had run Travellers brand for 800 or so hours, (400hrs per change). During all this time, I have noticed a cold weather hesitation in the Traveller fluid compared to my fathers DK45se (my father and I purchased two of the exact same tractors at the same time back in 2015), which I had filled with Mobil 424. This hesitation is to be expected given the oil types, once warmed up, all is normal. I gave my father at the time 3 options to pick from, I rated traveller as perfectly serviceable, 424 as better, and SUDT2 as best. these opinions were solely based off of opinions from my reading. He chose the 424. So it has been interesting to feel the difference, subtle, but 424 feels smoother. I do not yet have an analysis of the 424, only his previous oil from the factory that was drained. That last oil change in 2022 for my own DK45se, I went with SUDT2, for no other reason than to at least try it out once. I will be excited to have the samples in for both the 424 and the SUDT2. I do also want to hammer a point home that I had made a few years ago here. Oil manufacturers can change their blends, an analysis from a number of years ago, may or may not apply well to the same "branded" oil today, but it is certainly better than hearsay.
