Crappy air flow.
Without digging into specs, I'd guess that the high-end cars do come with oil coolers. Heck, my 2000 Celica had one.
I think it would do Nissan well if they'd look at revamping the entire cooling system, no just the oil system. Oil temps are at the end of the chain. If the engine was cooled adequately, the oil temps wouldn't be so high.
