Thanks for the prompt analysis of my Mooney’s oil!  I was so glad everything looked OK.  The winter was so frigid that we didn’t fly much, so I was afraid both the airplane’s oil and my arteries were full of sludge. We just came back from maintenance with 8 new spark plugs (4 fine wire for the bottom and 4 regular on top), and fresh oil to start the Spring season. No excuses for poor metabolism! Thanks again!
