Pumps use a 30-weight non-detergent pump oil. Don't use motor oil.

Why did oil pressure change from 40 average to 60+ at start down to 30+ at idle, after new engine was put in?

An old engine will normally show a lower oil pressure, which may be due to worn bearing, a worn oil pump or both.

A new engine with good bearings will normally show a higher pressure at revs than at idle, and a higher pressure when cold. Putting a worn oil pump back in a new engine (never a good idea without a thorough checkup on it) will modify this situation.

Just going on the readings I'd say your situation now is quite normal. You may even be able to change to an oil one grade less viscous, say 10W instead of 20W depending on your winter temps.

What grade oil do I use to change out on my Chicago Pneumatic RPC-561VNS? The manual says a compressor grade non-deturgent oil should be used, but does no specify a grade.

Hi and welcome to FixYa, I am Kelly.

Compressor grade oils are basically SAE30 W oil. Read this:

Rol-Air OILCOMP30W34C Air Compressor Pump Oil - 30W Quart features ,
Specially engineered and tested to match the requirements of Rol-Air air
compressors , Provides superior rust and corrosion protection.

I.e SAE 30W oil / the same thing you would use in an older lawn mower engine or generator.

What they don't tell you is because they have re-labeled the 30W oil to OILCOMP30W they can charge you big time for SAE 30W oil. The only difference is the label.

Thanks for choosing FixYa,

What kind of oil do I put in my Comet AXD2524G-T pump?

If the Comet Pressure Pump Oil is some kind of a
Synthetic Oil that supposed to be extra effecient than
an ordinary oil, then that will cost extra. If that is ordinary multi grade engine oil (SAE 20 - 40), then, you
can buy over the counter. Most synthetic oil have additive that give extra longer life to all moving parts.

Engine knocks when startup but disappears after engine warms up.....could the oil pump be defective.......what about the knock sensor....

Its probably lifter noise,check what grade of oil is in the car or change it to a slightly thicker grade,i would expect that the car has a lot of mileage on it,if the oil light goes out quickly on the dash when starting its not the oil pump(very uncommon),knock sensor is for ignition timing to stop pinging,nothing to do with your noise,generally its engine wear
