just bought a 2011 NH track loader with 250 hours and need to add some hydraulic fluid due to a leak on an attachment. I am new to all this, so may be a silly question but the owner's manual says the optimum fluid for my area is a good 10W-30. I don't know what is currently in the loader. Is it ok to add this fluid without knowing what is in it?
