How much usually is the miles per gallon on 2015 ram 2500 diesel cummins? 2wd or 4wd Can't find the mpg on the internet.
Forum Discussion
All tests and independent comparison test results stated in black and white repeatedly that the Cummins 6.7 is the thirstiest of the 3 pickup truck diesels by far. A good reason why the MPGs are not given/written much for the buying public to see.
