Just picked up a Robinair 3cfm vacuum pump (so I can finally do all my own ac service). The manual suggests changing the oil after every evacuation. For my purposes, will probably only use it once a year, then put it back in the box. Should I change and refill the oil before storing, just empty the old oil and store it dry, or leave the old oil in?
Thanks,

Old oil is fine for storage. Never store a pump drained of oil.
