This has been discussed elsewhere and in my opinion is a non-issue as the oil is constantly being turned over. I guess I'm taking the long way to say that I am sure they, the dealership, won't do the extra work involved to drain your oil cooler if mounted "up" and that it wont make a difference anyway. Some here have said that they may themselves "drain" the cooler using positive pressure once or twice a year....if you track the car I can see where you could make the argument to drain the cooler. I installed mine facing up and don't plan on "draining" the cooler directly at all. Hope I didn't beat your question to death but I too thought about this before installing the cooler....good luck.
