Fly lean of peak engine operations like a pro with a Continental or Lycoming engine, I will teach you how to extend engine life with lower CHT's and save gas with NO ETA penalty. Remember, your car runs LOP automatically, no reason why you can't run LOP in your airplane manually with RPM and Mixture settings you understand.

LOP FAQs
ROP stands for Rich of Peak, that is, a richer mixture than the one you need to fly at peak EGT and you are keeping the cylinders cool with excess fuel.
LOP stands for Lean of Peak, that is, a leaner mixture than the one you need to fly at peak EGT and you are keeping cylinders cool with excess air. Fuel is expensive and Air is free!
Now that we know what ROP and LOP mean, we can define a simple rule of thumb to avoid any issue during flight.
Let’s divide our “engine operations” in three parts based on the percent of engine’s power output. To know percent of Maximum Continuous Power (MCP), base your engine settings on the reference tables in your aircraft POH. You must have balanced fuel distribution to each cylinder, correct timing on both Mags and correct spark plug gaps to run smoothly LOP.
