I was in the dealership yesterday talking with the service advisor and we got to talking about the numbers of higher mileage Titans starting to come through the doors. They were all healthy.....just being used up...and quickly. These were all oil field trucks being driven daily from well site to well site on really crappy backroads. One 2004 truck had 175,000 km's ( 110,000 miles ) and another 2005 had 250,000 km's ( 155,000 miles ). They both still ran great but the guys were doing bi-weekly oil changes with the mileages they were putting on. It was just good to hear that these trucks are lasting well under harsh conditions.
