Hey there. My name is Dave. I am trying to dome best to maximize the fuel economy of my 2012 Ram Hemi.

Welcome Dave, is it an auto transmission or manual? what type of driving do you do, mostly city or mostly highway driving?

Dave,
welcome.
1 adjust the nut behind the wheel
2. get a scangauge (see link in my sig)
3. air up tires to 40+

Take a look at the 65+ hypermiling tips, it's amazing how much can be gained just by "adjusting the nut behind the wheel", the one that connects the steering wheel to the driver's seat. ;)

Thanks GRU. its an auto 6spd. I drive 65 km to work.
Mostly highway, couple of small towns to go thru.
