All Cat's suck? Really? Hmmmmmm....
I've got over 6,000 hrs combined on 4 pairs of C-series engines from C-9's - C-30's and no problems. (though i have had trouble with the 435 hp old 3208's but that was an issue more akin to the lack of competence in the service technician we used at the time who was not Cat certified)
Not to mention Cat's offer one of the best warranty and service packages out there for operations outside of USA proper.
In contrast i've had serious problems with Detroits, MANs, Cummins, and Volvos over the years.
Cat always has been, and always will be, the brand of motor for me.
