I get 20-21 1/2 driving freeway 60-65 (mostly 60) If into headwind then less. Mileage was 19 in beginning of May when I first bought it. Mileage increased along w/power ( my perception) around 800 miles. 09 Sahara 18" tires

Comparing the CRD with the 3.7 V6 is not fair, but here goes: in town my 6 spd CRD gives me 23-24 mpg provided that I shift up around 2,000 rpm. Highway consumption drops to 19-20 mpg cruising at 75-80 mph. Check the low rpm

This is true. The unofficial speed limit in NJ seems to be around 80.
