My truck has the 36 gallon tank and on the highway empty I can get 600 easy. 700 if I go 65 mph or less.

 

must be nice I got like 530 miles out of a tank I could have pushed it. the light wasnt on yet. but I didn't do it....

 

I'm only getting 400 out of a tank. 1/8 tank left 06' Mega Cab CTD with only like a 27 gallon tank????

 

My best ever was 703 miles on a tank. Usually I don't run it that low, so about 600 is very common. I have the 35 gallon tank, but once the pump kicks off I take the time to pump 5 more gallons in it to fill right up to the filler neck. That tank that was 703 miles I put 35.1 gallons in and the low fuel light was not on yet.

 

What GAS TANK size options where out for the 06 Mega Cab Auto tranny CTD???

 

I have a 30 something gallon tank in my truck not sure but when i fill up normally add 27 gallons or so.
A lot has to do how you drive.
If you race the engine to speed = poor fuel mileage
3.73 gears driving over 65 mph = poor fuel mileage
4.11 gears driving over 55 mph = poor fuel mileage
Duel Rear Wheels and 4x4 loose a little off the top also
winter blend fuel don't help out in the mileage dept.


19.271 mpg 531 miles to 27.9 gallons that was two weeks ago not sure if it was winter blend that was in TX
and my last tank I got 17.02 mpg on winter blend witch is still ok in my book. I'm getting a little better at driving using my cruise and keeping my speed down. not racing the engine helps out a lot I'm not jumping on the skinny pedal to show everyone I'm a bad ***.

 

ha ha ha cheater HA HA HA HA HA joking around
I don't do that when it clicks off I'm done.

 

Just got the truck so thats probably why i havent gotten the mileage out of her that i would like. First diesel i have owned so i am learning how to drive it. The gas mileage meter still says the same as when i bought it, so maybe the other person drove it like me???? The only mod it has is the K&N filter and intake. Makes me wish i had the stock airbox laying around to see if that would help???

P.S.
I love my mega cab!!

 

Doesn't this depend on short or long bed versions. I had an '08 duramax for work and it only had a 25 gal tank. Fueled up every other day with it. But my LB dodge has a 35 gal. I go an easy 600 miles.

 

my long bed 98 has a 32gal. acording to the sticker.... oh wait, it used to be a v-10 maby thats why?
