Hello everyone, I'm new and this is my first post.

I just bought a 2007 Dodge Caravan 3.3l engine.

I am wondering was to what kind of fuel economy I can expect.

Right now I get approx 490km per tank, I drive at 90km/h.

This seems rather low to me.

 

I get 25 mpg with a 2003 town and country driving at 65mph. 400miles per tank of fuel

Welcome to DF
I drive a dodge avenger and it gets 28 mpg. I would say if you are getting 22 to 25 mpg you are doing okay.

 

So you're getting roughly 15 mpg(300 miles with a 20 gallon tank if you use all of the fuel). Especially at the speed you're driving, that is really low. Be sure you are in 4th gear with the torque converter locked up(you can count the rpm changes as you accelerate). Other possible issues are a dragging brake caliper, worn out plugs and wires or an O2 sensor badly in need of changing.

 

I have a 2007 Grand Caravan and get 17mpg in city and 24mpg highway.
