I am having a problem getting my oil temps up and oil pressure down without an oil thermostat. Will try blocking some of the air flow this weekend. Is 10W-40 or 10W-30 to light for the gearbox during the winter months?  I plan to run the engine for at least 20 hours on the ground and switch back to Mobil 1 for first flight.

Next best in mineral oil is Shell Rotella.  15W - 50 or similar.

Tracy,
 
What oil do you recommend for breaking in a new engine that is also acceptable for the gearbox? Bruce T said to replace the Mobile 1 for 10-15 hours so the apex seals will seat.
 
Thanks,
