scubaduderon 18 #1 Posted August 27, 2017 Wouldn't you know it? I just eyeballed the mobile one 10-30 as I was about to pour it into my empty Eaton 1100 hydrostatic transmission and saw "High Milage".... I accidently purchased the high milage version of Mobile One. Do you guys think this will harm the hydrostat, or should I just use it? I looked into the difference and folks seem to think that it has a higher detergent content and also has "seal conditioners". Should I just forget about it for the night and go in the morning for some regular Mobile One? Thanks, Ron I did pour a small bit into the oil filter. If you think this is a problem I'll take it off and pour it out... Thanks again, Ron Share this post Link to post Share on other sites
953 nut 55,860 #2 Posted August 27, 2017 I wouldn't be at all concerned about it. Any oil you buy today is equal to or superior to the oil it had in it when it left the factory. 10 2 1 Share this post Link to post Share on other sites
scubaduderon 18 #3 Posted August 27, 2017 OK then, high milage it is! Thank you! Ron 1 Share this post Link to post Share on other sites
PeacemakerJack 10,739 #5 Posted August 27, 2017 (edited) I've been running the same oil in my Wife's 523D Eaton hydro for two years. Happy with it thus far!!! I say, "Go for it". Edited August 27, 2017 by PeacemakerJack 1 Share this post Link to post Share on other sites
scubaduderon 18 #6 Posted August 27, 2017 OK, put the High Milage oil in. Seems like it's a lot smoother than before. This tractor is new to me, and I'm not sure how many hours were on the old oil, but I'd say that Mobile One works pretty good! Thanks again, Ron 2 Share this post Link to post Share on other sites
squonk 41,397 #7 Posted August 27, 2017 I use the " High Mileage " Mobil 1 INSTEAD of the regular in all my hydros. 2 Share this post Link to post Share on other sites
lynnmor 7,354 #8 Posted August 27, 2017 Most of the high mileage motor oils have more ZDDP than their regular oils. That is a good thing because it is an anti-wear additive that the government wants out because it has a negative effect on catalytic converters. ZDDP has been used in motor oils for well over a half century. Using the "high mileage" designation lets the manufacturers get around the government edict........ for now. 2 1 1 Share this post Link to post Share on other sites
PeacemakerJack 10,739 #9 Posted August 27, 2017 (edited) With the transition of most cars from a flat tappet valvetrain to a roller valvetrain, high levels of ZDDP aren't as necessary in modern engines. However, I think they have found that it is more damaging than they originally envisioned by taking it out--especially on older motors. I try to always run a ZDDP fortified oil in my older engines or at least an additive containing it. I think that it is advantageous to the hydros too, as stated above...

scubaduderon 18 #10 Posted August 29, 2017 Thanks you all for your input. I wen't with the High Milage Oil and see no problem. Some time ago I added a ZDDP to the engine oil too. Thanks again, Ron Share this post Link to post Share on other sites
