Brian, A lot of Bosch numbers have a 0 in front of them for part number expansion. Some companies tend to drop it. My 2000 Bosch price sheet still has the 5 digit #. Oil Filter # 72150 is the correct one to use. I'm sure the Mobil One filter is good, but is it worth trying if you don't know the specifications for it. The Bosch and others are proven.
