Re: 6.2 diesel owners
6.2, SM465, 4.56 gears, 39.5" TSL's...16.2 mpg steady freeway @ 65 mph. Mixed driving gets me about 15.5 mpg.
About the only thing you can do for better mileage is get the cruise rpm's down to approx 2000 rpm. I'm planning on an NV4500 by mid summer. With the NV4500 and some 35" AT's my cruise rpm will be 2100 rpm (instead of 2650) and the mileage should be really close to 20 mpg.
I might also be able to hear myself think then.../forums/images/graemlins/crazy.gif
BTW, we do have a diesel specific forum...you might get more input if this was posted there.
