I'm new to this, so I'll take this report for what its worth
Purchased my Cherokee 140 (Lycoming 0-320-E) in April 2018. Put 33 hours on her then changed oil 17- July. At oil change, engine and airframe at 3652TT with 1613 SMOH in 1972. #1, #3 #4 cylinders 219/hrs STOH and #2 44/hrs STOH.
Burned 2qts oil in 33 hours
Edit- I was a little concerned with age time since major but this report is helping to ease them.
DENNIS: Thanks for the notes. Universal averages show typical wear for this kind of engine after about 30 hours of oil use. Next to those, your metals match up nicely for the most part. Only copper is on the high side, but that's typical for a Lycoming running 15W/50, due to a harmless reaction. There's no obvious sign of wear-in from the new #2. We're not sure if it already washed out or if the cylinder just fit in nicely to begin
with. Either way, there aren't any problems in these results, so just check back at the next oil change to start trends. No fuel or water was detected.
