So I dug into this a bit, hoping to find out what pump they used, but only found this:

Who seems to have died...

and thought it might be an IMC, but if so, they don't make it any more.

Bummed.

Question about your case K518V30S air compressor
by: Shane

I have a similar looking air compressor and can't find any info on it. Do you no the cfm on yours? Mine has a model number K518V30 on a 80 gallon tank with a 5 hp motor.

amsoil?
by: Doug in s.d.ca

Are you partial to Amsoil?

(If you are, Bill, as well as Doug - and many others I expect, wonder why? ....)

Pretty much any "compressor oil" should be fine, or 20 or 30 weight non-detergent synthetic should be fine.

Is that two or three stages? (just curious)
