02 24 valve Cummins - how to modify for mileage
#11
Hey Jason P - Just curious..what years where your other cummins and what mileage did they get..from stock to modfified, standard, or auto, did they have 4.10 gears, etc? I am curious that's all. My 02 extended cab, 4WD, all stock, 265 tires gets average 15.8 mpg - that's pretty darn good..esp for stock! I do have a gentle right foot though.
