The 95 E320 is not OBDII. It has a built-in diagnostic module located by the battery. You can build a homemade coed reader for under $5 from Radio Shack parts. The link below has all the detail you need to read the codes yourself.

The oil condition would not affect the check engine light.

You can still read codes without the code reader. Just press button #2 for 2-4 seconds and count the number of flashes, repeat for the next code. The code reader is useful to get more specific codes.
