I purchased a new 2006 Dodge Ram 2500, Cummings diesel, auto, 4X4, LoneStar package about 5 weeks ago. I was just curious in that my mileage estimator always reads between 16.8 and 17. 8 yet when I fill my truck and manually check the mileage the truck always gets 15.2 MPG. Is the estimator always that far off in it's calculation? Also is that about average for that truck? I hear about others that get much better mileage.

I now have 3,000 miles on the truck and I love it! I have driven Fords for over 20 years and am a new convert.

 

Dont pay any attention to the feel good monitor.Your mileage is about right on paper for a CTD. It will improve after you get it broken in. My 2004 got about 15mpg when it was new, now Im getting 18 . If I go easy I can see almost 20mpg. Give it time and enjoy it. My truck is still stock.

 

Wait until the truck has in the neighborhood of 10000 miles on it.
Thats supposed to be considered broen in.

 

that 10k depends on how the truck is used... hauling alot, yeah... no hauling... no. give it 25k~30k. my mileage has been slowling creeping up and i'm at 50k for an '05.

 

DANG, Ive got 90,000 on mine already!![:@]O well maybe theres 300,000 more left on it

 

what year is yours?

I'd recommend the bypass system... easy install! good peace of mind too.

what does the bypass system do??

 

nice truck!!!

the oil bypass is a system that filters down to the 2 micron level. https://www.amsoil.com/storefront/bf.aspx

it allows longer oil change intervals.
