Since the ML320 holds about 7.5 quarts of Mobil One and has about 3 fans on it's over sized radiator, and the manual reads about 10,000 + miles between oil changes...
Couldn't I keep a nice clean - lubercated engine by changing the oil every 5,000 miles and the filter every other oil change?
I planned on going 7,500 between changes, but feel better about 5,000.
