Wow, that's amazing! I'll see what I can get on my trip tomorrow, 245 freeway miles each way

That tank was from Iowa City to Wheeling, WV. Stopped 4 or 5 times for bathroom breaks, food, and an overnight in Columbus, OH. Other than that, the cruise was set at 5 above the limit the whole way.

I also had the fortune of a strong tailwind for all of those miles. 20+ mph directly behind me.

Wow! I'd take 30mpg. I have a trip to Portland Oregon soon - 450 miles can't wait to see what this does. :cool:

Taking my first road trip in the beast from CO>SoCal>NorCal>CO and am hoping I get over 30mpg. Currently holding steady at 25mpg with 80% highway.

I'll report back what the car says (too lazy to do the math myself) as I go along each leg of the trip.

I forgot to to add that I have > 5k miles on the car

Diesel history
 

So my experience has been pretty consistent with the other posters here. I've got a 2010 with 30,000 miles and have averaged 25+/- (50/50 mix) with cruise control highway hitting 29/30. I haven't had any engine issues at all and love the low end torque. Biggest headache was starting it at a ski resort when the temps were -20F the night before and I had to wait for a minute or two before I was able to start it.

I like threw diesel enough to have another one on order for delivery at the end of the month.

thanks for the awesome responses
