If you crunch the #s More CR were sold form 2003-2006 ,Thats 4 Years then all the 12s & 24s together form 1989 to 2002. I know many owners with 300K+ miles with just minor repairs still on factory injectors( Most have have heated the Advices and added Auxiliary Filter(s), you can't blame Bosch for the worthless fuel in north America. . look at all the china POS filters on the retail Pumps through North America... If the blame needs to be Placed. . I put on ALL the Retail sellers & the GOV of both Canada & US for NOT requiring Proper filters on ALL retails Pump. . Heck they MAKE ULSD to satisfy ALL the tree hungers ,But destroy all CR engines for Lack of Filters its BS. . I have stomp this horse to death. . YOU cannot have proper filtration with certified Internal combustion filters. . Either Auxiliary filtering or Quality retail filters. WHY even allow ANY harmful products into factory Tank#@$%!
