[QUOTE="trobbl, post: 131304, member: 20498"] The service manual for the 520, 530 and 533 calls for 10W-40 SE for the hydraulic system. They recommend going to 5W-30 when the starting temp is below -10F. I've always had my 530 in a garage heated to 45F in the winter, so I can't comment on how the hydraulics sound or behave when starting out in colder temps. The ISO to SAE chart says ISO 46 is equivalent to 15W or 20W, so you may be right about having to warm it up a bit in colder weather before it can flow well. [/QUOTE]
