It's not just the oil that needs to warm up. The rest of the system, parts & housings needs to get some heat in them. A proper warm up would consist of moving all hydraulic functions in harmony to allow all parts to come up to temperature equally. Moving the loader, backhoe & 3pt controls to put some heat in them. Nothing good about getting the transmission hot & sending the hot oil to freezing cylinders.
