I just did a 2500 mile trip in my truck not towing and out of curiosity kept track of the mileage ( something i dont normally do ). I drive relatively fast 75-85 and had one tank that was 6mpg less than the others. I can only account for that as being poor fuel quality. In the past in other trucks i have seen 1-2 mpg difference between fuel stations but never this big of a difference. The worse tank by the way was from Flying J in Wells NV.

2011 GMC 4wd crewcab dually dsl First tank was G diesel of which when i use regulary i get better mpg with less regens. I havent calc'd all the tanks so far but one tank in Jackson Hole Wy was B10. I will get out the reciepts and calc it all. The B10 tank wont representive of the rest as it was slow going through Teton and Yellowstone. I'm a believer in the G diesel as it has proven itself http://www.advancedrefiningconcepts.com/index.html
I went through all the reciepts and the mileage and had made an error. Low of 15.4 to a high of 19.2 mpg Most of em were in the 16 range Pretty good for 9k lbs of truck and people at 75+ mph most of the time.
