ive heard of these on big rigs and a guy i was talking to has a 99 7.3. he said get to get a bypass filter. it hooks up to the current filter location and filters the oil down to 50 microns or something small. he said he never has to change his oil anymore just test it every 5k miles and add as necessary. anybody have one of these. said he got it for like $150.
