I picked up some filters and fluids to service my BX with over the holiday. Did not look at my records because I knew it had been some time since I had last changed fluids and filters other than oil. It's been almost two years since I've changed the hydraulic fluid and filter but I've only put a 110 hours on the BX during the two years. Should I just store the fluid and filters to avoid waste or does time break down hrdraulic fluid?
