im still on my first tank of fuel and the trip computer says im only getting 11.3 mpg. is this a normal thing on the first tank? the truck is stock and has under 300 miles on the odometer. what can i do to raise the mpg?

 

Break it in. It will improve with more mileage. My 05 3500 started the same way, I have 54,000 on it now and the truck weighs 9500lbs. and am getting 17 mpg.

 

let her run before you start looking at the mileage.

when I pulled off the lot I was sporting 13.5mpg. . .my last tank 37K later was an impressive 19.5!!!

 

Drew...what are you doing to get such good mileage???? im baffled. i see alot of people here getting 17,18,19 and im getting 14-15. ???

 

My 06 CTD regulary gets 15.5 mpg city and 19.5 hwy unloaded. Oddly enough I did a field test with the tail gate down vs. up and mpg highway was 1.5 mpg better with the gate up. Go figure! Drew's Brew does an engine good as it makes it run 50% quieter and bumps the mileage 1.5 mpg for me. The above mpg quotes are city, not using DB and hwy is using DB.

Inow have 23,000 on theclock. The biggest jump in mileage for me was right around 8,000. It was sh*tup until 4 or 5,000, then I started seeinggood improvement.

Good luck!

 

thanks for the advice guys. i will get someiles on her before i panic. im going to try drews brew as well. should i have a certain amount of miles before i use drews brew?

 

Crazy kid,my guess is the 4.10 gear.Filled up in knoxville,Tn friday night,drove to Danville,Va got 21.5 reading on the overhead,not only was that good,but diesel fuel was 2.29 a gallon.Keep in mind I wear a size 9 shoe and 8 times my shoe size is is my age.....ah man to have a truck like this in my yout,oh well,something to look foward in thenext life.

Sorry badapple,when I start talking about my truck well, it's kind like a senior moment.Use the advice from this board...drive it like you stole it,put some weight in the back and most important....lean on these guy's here for info,they know their stuff and wont mislead you.

hummm?? this mileage thing is a mystery to me.

sorry badapple didnt mean to take over.

 

I have 13000 on mine (had it since october) and i am getting 21 highway handcalc with the brew. I am loving it, as long as i keep it under 2000 rpms while on the highway.
