I've gotten better than that, it was relatively flat, but it was a 1/2 % downhill grade over 60 miles. I still haven't won the lottery tho. 😄🤑🤑
I drove down out of the mountains for that many miles and not sure I cracked 20mpg when I had my 6.2 😳🤠😳

It's weird, cause I've gotten over 18 mpg going across town before, but some days I can't break 12. My average is pretty low on my 1500 at about 12.1 mpg just over 10k miles.

Just starting to get good on the 2500HD. I sort of wonder about these computers occasionally. I did hand calculate a couple tanks and it seemed pretty close tho.

You should buy a lottery ticket if that 50 miles was anything but downhill with a wind pushing you 😅
Nope, that was all Rt. 78 East in NJ from Bloomsbury to Newark Airport. So mix of NJ hills, coastal plain and rural traffic with Metro-NYC urban traffic. Maybe I had a tailwind!
