go with the recommened oil weight from nissan - should be 5-30 or 10-30.i would also use castrol gtx or castrol high mile oil.

20W50 is too much for that engine. Even in FL 10W40 is enough for your Nissan.
Use a good quality oil, like Pennzoil and replace it every 3K miles.

what about straight 30 or 40 versus 10W?
