i have been wondering, my first tank of gas which lasted the first 250 miles i only got 14.7 mpg. it now seems on my second tank that i am getting 16.5 mpg. is there any reason that in the inital break in of 250 miles, the car was getting less mpg? you should be getting more mpg in the first 250 miles since that is when everyone treats the engine nicely!!!

Like a fine wine, your mileage should continue to improve up to about 8000 miles, then level out. This is normal.

My first couple tanks I got like 15 or 16 mpg. The truck has just over 3000 miles now & the last 2 tanks were over 20 mpg.
No idea why, but it appears to be the norm in this group.

I can't seem to get over 14 in the city and the best I have gotton on the highway on cruise control at 65 is 18.47 mpg. meh....

I've noticed with my Dak's at the start mpgs sucked 9 to 11 but as the miles climbed so did the Mpgs till they got right at or a little better than advertised. So hang in there it will get better.epper:

hopefully, at 6,500 miles so far and still waiting

most all vehicles when new get worse gas mileage because of the tightness of the new engine

as rings. bearing and other parts seat in and clearances settle the engine becomes more efficient and milage goes up

as us drag racers say (it always runs the best right before it blows up) :SHOCKED:

9 mpg? Ouch! The worst I've seen was 13 mpg draggin a 2200 lb trailer.

medicguy, mine was the same for the first 2 tank & since has been on the climb about 1 1/2 to 2 mpg the last two tanks. So keep the faith & the force will be with you.:beerchug:

wow!!! you must be jumping on the gas after every light!!! Maybe you should try adding X-1R....that stuff is the only additive approved as "Space Technology" by NASA! I put it in my cars and notice a smoother idle and slightly better gas mileage (3-4%). It is expensive though about 15 bucks for a 12oz bottle. later
