First tank fillup after 1 week and a trip to Phoenix. 390.1 miles @ 17.801g (rounded to 17.8g) and my wife said she topped it off better this time than the first fill up at the dealer. So, that's 21.91 mpg. And since about half was on the freeway doing 75 mph and the other half was mostly in the city, not too shabby. I think with a little finesse, we can massage out 23 mpg. V6/6 speed manual is a great combo for commuting.

 

Hell, the guys at work have Chevy Z71s 4x4 getting 21 mpg with Vortex what not power plants and the 2012 Ford F150 guys are getting 23 mpg with their 4 wheel drive trucks. Man they got new trucks, black with leather and boredom written on the VIN numbers............Me I got a humble paid for 2 years ago, owned since new Inferno Red bad *** Dodge Hemi and a Hemi is an experience not just a truck. So, I get 13.8 to 19.0 mpg with paper and pencil or a pen if the nun lets me use one. Then of course I may be telling the truth about my ride...........

 

My 07 1500 Mega Cab 4wd gets 9.1 calculated. Not sure why the console displays approximately 15. I've only put 3 fill-ups in since I bought the truck and all are around the same mpg's.

 

I get 13-14mpg, 2002 1500 4x4 5.9L with only 28k miles.

 

Lucky...I use two and a half tanks just going to and from work every day.

 

how long of a commute do you have omg, 2.5 tanks in one day? WTH?!

 

lol...5.7 it's per week...I got a 68 mile commute one way.

 

2005 Ram 2500 crewcab 2wd hemi and auto. Bone stock gov surplus truck with 85852 miles. Last tank was 15.59 with a best of 16.54 and a worst of 12.31.

Just installed a VOLO FS3 addon chip. We'll see if it does any good.

 

2005 quad cab 4x4 5.7 HEMI 77k 15-16MPG highway and as low as 10MPG in lots of city driving. Only thing to save fuel is a tonneau cover but that is debatable, basically just take it easy to not get horrible MPG.

 

try resetting the overhead display it will begin to calculate as of the reset.
