6.4 Hemi Trucks

Ok got back from indiana,390 miles round trip-trucks computer's average qas 14.8mpg-so i did the math and came out exactly at 14.8 mpg-i was surprised the computer was dead on because my diesel trucks never figuired that correctly, average speed 70-75 on interstate but shitcago was a stand still, not overly impressed BUT no depressed either cause mu diesel would have cost $120 to fill and this only cost $65.00 so that's a win, i really couldn't tell if and when any cylinders cut out with the mds and stupid me i didnt really pay attention to the rpms DAH !!!!!! Also something to remember we are on winter blend of gas here in good ol wisconsin-steve
