I bought my 06 Chevy Duramax (2500HD) last May w/ 27K miles on it. I run approx 80 miles a day mixed driving (maybe 65/35 hwy/city). I get 20-21 daily driving, sometimes high 21's. In winter it drops to 19-20. Have not done a pure road trip with it yet. I run stock exhaust, stock air intake, Shell Rotella 5W40 full synthetic, and PowerService fuel additive. I just swapped out the factory tires at 56K and don't know yet what effect that will have. Good Luck!

I have a 2004 F350 4WD 6.0. It is a piece of crap. Had a 2000 F350 7.3 that I sold with 290,000 miles. My 2004 has 69,750 miles and now needs heads and head gaskets. BTW the original Head Gaskets went at 43,304 miles, 2nd set at 52,010 miles. Now that it is 6 mos. out of wty they tell me my heads are probably warped. I also have a 2006-2500 Sprinter with the extra high and extra long WB. Maximum mileage is 22MPG traveling 55-60MPH. If you read their brochure carefully the estimated MPG is on the short van w/short wheelbase. Don't get me wrong, I am tickled to still avg 19 to 21MPG overall.

Pickupwbb----Sorry to hear about your Head gaskets ... I have a couple of questions about your 6.0. ltr, as I am trying learning more about these motors,
1) Is yours a "p" or "n" Block engine? you can tell by the vin in the 8th position.
2) did the dealer ever replace your EGR?
3) what kind of programmer were you using?

You will always have trouble with a diesel's performance cold. They are like old carberator engines. That is the down fall to owning one. I've worked with many different makes from Cummins to Cats and they are all the same. If you have a problem with a cold start you might want to have your glow plug harnesses checked. I had to replace the ones on my 2000 7.3L just before it hit 100,000 miles. I just had some work done to mine so we will see how my fuel mileage plays out.

I was considering a chip for my '06 Dodge Ram 2500 diesel but it sounds like the risk are too great (too complicated) for me mess with since I put so few miles on the truck and pull a 32' trailer with full living quarters and 3 horses in the mountains.
I'd rather put my $$$ in fuel cost vs. truck repairs.
