I just bought a L2900 GST w/fel and 630 hrs. I was wondering if someone could give me some info on maintenance. What is the best motor oil to use in it (rotella 10w-40)? How many quarts does it take? What kind of hydrolic fluid does it need? And how much? And I would appreciate any other maintenance info you would have for me. Also, one other ? I want to load the rear tires possibly w/ antifreeze, can you do this without having tubes in it? I had one guy tell me you could load them without tubes as long as it was noncorrosive. Thanks for the info.
