My RV-10 has an old engine (about 5,000 hours on it). It was top overhauled before installing in the -10, and it had installed all new, nickel cylinders at that time.
The oil consumption was always high but during 4 years (and 300 hours) I owned the airplane, the consumption increased from 1 quart per 3.5 hours to 2 quarts per 3 hours. Oil analysis shows increased nickel but that is in line with nickel cylinders.
This is still in-spec by Lycoming standards (current consumption 0.66 qt/h vs. 0.87 qt/h maximum) and my mechanic recommends just adding oil. Looking for a second (or third or...) opinion
Thanks!
