While a finned oil pan may help (surely will), has anyone bothered to

great,

and the oil side contact with the fins will be essentially stagnant.

Compare

that to an oil cooler with extra area fins, and air blowing through it.

Your right Bill. It just sounds like a good idea. Can't hurt and would

look cool :)

I'm with Bill.  When you look at the numbers it doesn't make sense.  Your
time and money could be better spent elsewhere.
And in some scenarios, it can be a net looser.  In my plane the oil would
run hotter if the pan were finned due to heat pickup from heat radiated from
the exhaust system.  My pan is actually insulated for this reason.
