Re: Oil Delta T was: 11th test flight
I am wondering if there
is a minimum temp for the oil. My usually varies between 140 and 160
depending on my power and attitude. It will drop into the 130's in a long
descent. The engine is general is still warm based on coolant temps.
Does anyone feel that I need to keep the oil a little warmer for the sake of
the engine?
Dave;
I
recall David Atkins suggesting not to operate below 140F. I would think
this an issue only when under significant power, and not when in a descent. But
I suppose a full power go-around starting a 130F might not be the best thing.
I
don’t have a thermostat in the oil circuit either, but will add one later
if I have to.
