Best guess as to fuel mileage on these trucks

Gang - I am trying to put a pencil to my options and as such am trying to figure out what each of the following would get as combined MPG for my spreadsheet.

In an effort to compare apples to apples, all will be 2019 models 4x4 Crew Cabs. Assumption is that 80% of miles are highway miles traveling between 60 and 70 MPH. Below are my best guesses based on the research I have done so please edit as you see fit and I will hopefully be able to hone it in from the responses.

Sierra 2500HD 6.6 Diesel: 18 MPG

Sierra 2500HD 6.0 Gas: 12 MPG

F150 3.5 EcoBoost Gas: 19 MPG

F150 3.0 Diesel: 23 MPG

F250 6.2 Gas: 13 MPG

F250 6.7 Diesel: 16 MPG


Also, probably a dumb question but would it be safe to assume that the Chevy's will perform very similarly to their GMC cousins?

Additionally, I know that I have excluded the Ram's. I'm just not a fan cosmetically. However, I am a fairly practical guy so feel free to include that information if you have first hand experience and so desire.
  • Here is a good website to search real world mileage. Goes by hand calculated numbers not lie-o-meter like most do here. Not 100% accurate, but it is just about the best you are going to get.

    OP, you would probably do better going by cost per mile since the price of fuel is different between these vehicles.


    I have the cost of the fuel type built into the spreadsheet. Just a different way of skinning the cat I guess.

    It wouldn't say that it is any bigger of a concern than anything else but it is part of the equation that I want to take into account. I generally over analyze things so I guess I am just doing what I do. lol
