Howdy All…I just bought my first CTD (1050 miles) in fact, this is the first diesel I’ve ever owned. It’s a Silver 3500 automatic 4x4 SWB. I have a few questions about my new truck. I know these are going to sound stupid to you diesel pros but, hey, I’ve driven gas pushers my whole life. Ok, on to my questions: My truck runs about 2000 rpm at 70 mph is that what it is suppose to? Next, when I am driving around the Oil Pressure stays at about 40 or a little higher when on the interstate, but when I come to a stop it drops down, not into the red, but it drops to the lower black line. Lastly, what kinda of mileage can I expect to get when the engine is broke in? I am currently getting 15 mpg with just over 1000 miles on it.
