I am looking at buying a dodge dakota, a new one, and I was just woundering, how big is the difference in fuel economy between the v8 and v6? The reason fuel economy is somewhat important is because I am only 19 and will be going to school fora year, with not so much income, if I thought I could afford it i would go buy a brand new full size lol. But I cant, any help would be greatly appreciated, thanks. Jon

Well for what I have seen around 4.7 Dakota get around 13ish to about 16ish.
3.7 semm to be 15ish to 18ish. My 3.7 is four door 4x4 and gets about 17 all the time I drive alot of hwy.

I own a 2007 Dakota quad cab with a 4.7 V8 and I am getting between 15.4 and 16.6 mpgin town and on the highway I am getting between 18.6 and 21.5 mpg. Alot of this depends on your own driving habits.I used to have a 3.7 V6 and I can tell you that it takes alot more effort to pass another auto with the V6 and that there really is not that much difference in the mpg!:)
