Antifreeze used in that loader is just the regular green, as far as hyd oil they came from factory with an aw46 spec, any good quality tractor hyd oil works just fine too, which is all that i use in my repair shopAnybody have access to an operators manual for a Mustang 2054 or know what the antifreeze and hydraulic oil is supposed to be? Im looking for what antifreeze and hydraulic oil is supposed to be used in it and the capacities.
