The owners manual for both 5CFM Mastercool vacuum pump states CAPACITY: 5CFM = 8oz.

90065 - Mastercool 5 CFM Dual Stage Vacuum Pump
90066 - Mastercool Economy 5 CFM Dual Stage Vacuum Pump

The website states OIL CAPACITY 18oz.

The same owners manual states CAPACITY: 1.5CFM = 5oz. However, the actual owners manual for the 1.5CFM is different than this manual and states CAPACITY: 1.5 = 10oz.

I recently purchased the 90065 (from AMA) and the manual that shipped with it said 18oz. There's a 20 or so oz bottle of oil that comes with the pump and the directions also say how to determine level, a sight glass with a line across the housing; it took 18oz to bring oil level up to line.

Perhaps the one on Website is a misprint or something.
