Engine Analyzer Question/Lean vs Rich of Peak/Engine Longevity

[gwbraly]

>> do what the manufacturer tells you: stick with ROP.

Ernie, cut me a bit of slack, please, because my response is going to be a little bit "hard". It is not directed at you, but it is designed to illustrate the problem.

So your statement is "true" - - but only if one excludes each of the following manufactures from the scope of the statement:

Teledyne Continental Motors;
Piper;
Mooney;
Cirrus;
Lancair;
Lycoming;
Cessna;
Beech;

Each one of which specifically approves or endorses operation lean of peak for their most difficult high powered engines.
