Re: Oil for the hydraulic fan system
Reply #5 –
I think it is a bit strange that there is no specified change interval for the filters and oil in the hydraulic system. If there is one please let me know. The filters will not last forever and the oil should last a long time, but not forever. It does not get contaminated by combustion byproducts as engine oil does. Seems like once every 5 years would not be too often. I don't know of any easy way to do a complete oil change as about half of the oil is in the pump, fan motors, power steering, and hoses. It is relatively easy though to remove the oil and filters from the reservoir. I think most people just do that. I have been using Delo 15/40 in all the engines just like others to keep it simple. Any name brand oil with the same specs would probably be okay, but I don't mix brands unless necessary.
