What do you think?
1989 560 SEC, 140K miles
just started using quite a bit of oil. No leaks on the ground.
Spark plugs look OK
Seven cylinders measure 155 for compression
Second cyclinder back on the drivers side measures 95
What do you think is wrong?
How do I determine for sure?

Spark plug info
I just took a closer look at the plugs.
The cylinder in question and the rear cylinder on the passenger side show oil fouling
