How many miles on it so far and how are you measuring the mileage?

Some basic assumptions here:

Your commute is the 'typical' sort of thing, ~15 miles of mixed highway
and city.
Other trips are mostly pretty short. Shopping/neighborhood sort of
stuff.
You are in a northern-tier location burning winter-formulated gasoline.
You are likely burning 87 octane 10% ethanol fuel.

Under these conditions, your MPG is pretty damned good. Even if you
were burning 93 octane, that would be very good.

My 2.5-liter 5-cyl Volvo XC-70 gets ~18mpg overall-average based on my
typical mixed roads driving patterns. If I take a long trip on highways
where I can set the cruise-control at ~72mph (65 posted limits around
here), that jumps to 28-30mpg. My wife's 3-liter LPT 6 Saab 9.5
averages 14mpg for her typical near-home use. We just took a trip to
Washington DC last week (300 mile R/T). We averaged 31mpg including the
local driving about in DC. All of the above on 87 octane regular.

Our 99 Eurovan Camper averages 22 mpg on the highway. Around town,
~18mpg. It is a VR6 and driven gently. Lead-foot drivers pay a huge
penalty.

CONV What?
 Bought a 2006 conv in July with the 5 cylinder engine.  MPG stinks!  Only getting about 14-16 mpg city.  Anyone else doing any better?
