The compressor is new and the clutch is working fine. My low side is a little too low at 10-15 lbs and the high side is fine. The low side goes up to normal when I rev it past 1500.

Money is not the big issue. Don't like to waste it though. It's more curiosity. Or is it just an oil ripoff. I have a vane type vacuum pump and have it apart. It's nothing but a rotor spinning around a housing insert. Can't understand why any special oil would be required. Vapors are released thru a...
