Engine mixture guidelines
What damages the engine is excess oxygen and any combustion
temperature. Any mixture with a temperature drop means that
there is excess fuel. 25 C is easy to see on the gauge and
with a single probe assures that all cylinders are rich of
peak. A multi-probe system is best as is fuel injection.
At cruise power settings, you can lean aggressively. But
only the pressure wave of detonation will damage the
combustion chamber.

engine? I doubt
