Default Oil Coolers cause low oil pressure upon startup?

Ok, figure that you have to build pressure into the cooler, and its lines before it reaches the rest of the motor. After lots of starting, wouldnt this cause excessive wear on the bearings for starting with slightly less pressure?
Now, some coolers are mounted with the lines facing down, or facing to the sides, so they even "bleed" some of the oil back into the engine when resting, and because of that you have to now refill the cooler as well....

Opinions? Facts? Experience?
Thanks

An oil cooler would not cause oil pressure to drop if put together correctly. Depending on the size of the cooler it self and lenght of line you will need to add about a 1/2 to full quart of oil more. Mounting the cooler with the lines facing down or to the side is just a matter of fitting. But it is best to mount it with the oil lines to the side, not to let oil back to the motor when off, but to get all the air out of the cooler when the car is running.
We have done a lot of testing on varies cars and have found no problems with wear.

I don't think the oil drains out of the oil cooler when it's not running. I don't really think there's any thing to worry about. Most cars come from the factory now days w/ one.
