I used to have a Park Ave with a 3.8 back in the day, it had 275K on it and it was getting pretty tired...was underpowered and had some compression loss on a few cylinders, I added 20-50 with the Lucas oil stuff, and it brought the compression back up to an acceptable level, thought it wasn;'t a HUGE jump like a sleeve and bottom end job but it was enough that it didn't burn a quart a week and I got some power back.
