Torque to specs. I also use the Dow lubricant on the gasket instead of engine oil.

What is your opinion?

Lycoming says to change the oil in the O-320 series every 4 months or 50 hours
of operation, whichever comes first. IIRC, Continental said 4 months or 25 hours
with the O-200 with a screen. The recommendation for a 3 or 4 month change
period is pretty widespread. I'd be looking for another mechanic.
