Aight guys, this has been bugging me a lot lately. I know my truck is new (1100 miles) but my milage sucks. Im showing 11.9 on the overhead...I am starting to wonder if i am babying the truck too much to get it up to speed and sucking a bit more #2 that way. I usually slowly roll into the throttle letting the truck shift at 1700 to 1800 in a liesurly mannor. It seems as if most people even with new trucks are getting atleast 13-15 around town. My city driving may be a bit more extreme then most though and that could be a big problem. My daily driving is basically stop light, accel to 40mph and hit another stop light. I hardly get any cruising at speed in (da*n college town). In an average 3 mile streach that i travel often (to work) i will stop and accel about 6 or 7 times. I know that is sucking diesel, but i was wondering if maybe getting to speed quicker and putting my foot into it a bit more would help thus letting it cruise a bit longer at speed and at lower rpms. Also, what can i do to break this thing in? I know everyone says drive it like you stole it, or put a load on it, but i dont have a trailer to pull down here and i rarely have time to get back home to one. After 3 months of ownership this truck has probably seen highway speeds 5 or 6 times for short distances as i dont have much of a need to travel out of the town. Ive been told to just stick my foot in it constantly to break it in for around town driving but my pocket book would really start hurting if i did it a lot. Sorry for the novel, but any insight would be awesome. Thanks, Jason

every truck has got crap for fuel mileage at first but when we hit 10,000 it jumped up. may just need to give it a bit of time. and it don't hurt to mash the gass and haul a$$ from time to time, keep the cob webs out of it.

My normal comute is between 13 -18 miles depending on which way I go. Shortest route has 20 red lights and 3 stop signs. With 315s I averaged between 12-12.5mpg all city for the first 7,000-10,000 miles. Now at 45,000 miles and a number of peformance mods I average around 14mpg all city, 15-16mpg mixed. My mileage is still getting better. Last week all highway trip averaged 18mpg at 78-80mph. At 65mph I will get around 20mpg.

I try to drive rolling in and out of throttle smoothly in the city, but I do not baby it anymore. That really did not seem to help or matter much. I make sure that I roll into a WOT through all gears at least once or twice a week. On the weekend trips I do my best to make sure no carbon left on injectors or soot in the exhaust system.
