My Lycoming manual says to run 65-75% power for 50 hours or until oil consumption stabilizes. If I use a quart in 4 hours now how do I know it won't get better if I continue to run it hard?
Re: cylinder pressure and the notion that a cruise prop is beneficial. Does it matter if it's a 150hp or 160hp engine? 7.5-1 vs 8.5-1. What does that do to cylinder pressure? What about guys running 10-1? Lycoming doesn't differentiate in any publications I've found.
Why do they imply ashless dispersent oil is bad for a normally aspirated engine at break-in when they require it for turbocharged engine break-in?
