No, 6 year-olds should be in school by mid-day, not playing on mommies
computer!

As a 6 year-old mechanical engineer of some 30 years practice and owner
of an IO-540 equiped airplane, I find it somewhat disturbing that the OP
was NOT a joke.
Anyway, pat on the back - big hug time for the courageous aviator who
started his engine at **GASP** 25 F, after careful deliberation on
aborting the flight until Summer.
Catch my drift??

Perhaps with your extensive and pontifical experience you cold summarize
the findings of Shell, Chevron, and TCM of the percentage of wear that
occurs in the first 30 seconds of cold (ie, below 40 degrees) starts?


May I humbly pontificate that proper starting of engines (incorporating the,
appropriate for the temps and engine, oil) at 25F will NOT impact their
respective TBOs to any statistically significant degree.
I have many examples of this at the airports where I have been based and I
follow this practice on my own plane.
