These engines are very reliable. You can definitely change oil every 10K kms or 1 year without any problems.
However, I always change my Nissans every 5-6K kms even with very good synthetic oil. Why???
That's because I want my over 10 year old Nissans run at least as fast (if not faster) for 0-100 tests when comparing them with the same "NEW" cars...
