I've used the Rotella hydraulic oil. They sell at at wal mart here. I figured it was probably better than that cheap 303 stuff you see on sale for 29 bucks. I think the rotella was about 60 a gallon if I remember correctly. I've since switched to amsoil hydraulic oil which made a noticeable difference on cold weather startups with no whining from the pump.
