Mobile 1

The manual says:

Remove the oil plug (C) (Fig. 7) and drain the oil until it
slows to a drip, then close. Add oil to the pump by first
removing the breather plug (E). Add oil until the level viewed
through the sight glass (D) is between FULL (A) and ADD (B).
Never overfill or underfill the pump.
NOTE: The compressor is pre-filled with synthetic oil. We
recommend using a good quality 10W-30 synthetic motor oil for
this pump.

I suppose "Mobile 1" (Mobil 1) qualifies.

Oil fill

Normally, when there is a sight glass, the correct oil level is to the center of the dot.

Missing manual
by: Paul

Hi Bill, thanks for the posting...I have long lost my owners manual and can't find any info...Probably will go to Lowe's and buy the Kobalt brand semi-synthetic blend & just fill to top of the dot in the sight glass. Blessings!

Kobalt model 215921 oil
by: Bill

Odd that, the Kobalt model 215921 manual doesn't refer to what oil or what quantity?

Anyone have this info for Paul?
