All my stuff is older but don’t modern diesel 25’s and 3500s get about 28 to 30 mile per gallon nowadays?
Empty?
Lol no. My 2001 7.3 averaged 21. My 2003 6.0 got 23 average. 2004 6.0 got 17 but it was a 350 SRW 8’ bed. 2005 duramax dually was a pile anxious averaged 12.
My 2011 6.7 averaged 14 before full delete and 14,6 after. Keep in mind it was the lightest and smallest of them all as it was the only 250 crew 6.5 bed. All the others were 8’ beds and most were one ton plus the 7.3 and 6.0 Powerstroke was heavier than the 6.7.
The epa ****ed diesel and they aren’t done.
