How important is it to have a Chevy dealer service our Duramax?
I have followed the recommended maintenance schedule and changed oil and all filters myself, Rotated tires and checked axle fluid, etc. However there are things like checking air intake system, hoses, shields,etc. that I am not sure what to do. Should the truck go in periodcially to have these items checked? I sometimes feel the factory lists these things just to get service business. As long a as the main items are taken care of is this adequate?
