My O-470 230 HP Continental engine has ten quarts of oil
in the sump. It takes a relatively long time to heat up
ten quarts of oil. Probably longer than most climbs.

Paul, what about using a bigger pan on the rotary to carry more oil? Of
course, this would add weight, but it would be a larger thermal mass to heat
up, just like in the piston motors.

10 quarts is a lot - 2x the average capacity of a vehicle engine.

I think it might be a good idea. Greg Richter already has a big oil
sump on his turbo 13B. He mentioned cutting it down but that might
be a mistake.
