what can i expect to get out of a 05 dakota 3.7 quad cab 4x4 with an auto
also what would i expect with a 4.7 with the same setup?

 

My 05 4x4 gets about 15mpg city, 23-25mpg highway, if you keep it under 60mph, over 60mph 18-19mpg

 

also how many miles can i expect before i have motor or tranny problems

 

well lets see, i have a few mods along with nitrous and currently have 91000 miles on truck, also every 30000, miles i have the trans axle service done, only because of the amount of racing i do, but for an average everyday driver, they will last forever

 

And if you're me you get 15-16 highway thanks to setting cruise at 82

 

I get around 16-17 with my 4.7

 

anyone with a 3.7 v6 that can give some info?

 

I cracked 20mpg last weekend on the hiway. Around town I am lucky if I get 14. V8.

 

after the last 1000 miles on my 4.7ho quad cab 4x4 i have averaged 16.0 on the overhead (which has proven to be very accurate for my truck based off of hand calculations as well). I have about 50 miles of highway to my 8 miles of street driving each day.

 

16-17 mpg.
