My 04 DII gets 15.6 mpg average according to my UG.

 

??? Hwy, right? What about around town?

 

UG shows 15.6 as my average and I do about 50/50 (city/hwy). Guessing Hwy would be +1 mpg and City -1 mpg from that.

 

Ive always averaged under 12 in the city. I got about 15.5 hwy afew weeks back.

 

Not to turn this into a MPG thread, but my results are due to an electric fan and all new rotating assembly in the form of a top hat liner engine (not why I got it, but a nice side effect). They each netted me about +1 MPG each from stock but one cost $200 and the other $6K respectively. I realize 15.6 is still a long ways from stellar, but it helps.
