Drive long enough to warm the car up if you can. Those who commute 15
or 20 miles each way report mileage in the 50's. Those that typically
travel only a few miles per trip get in the 40's. So, yes, it is
driving style related, but no necessarily a style one can easily
control. You don't have to drive in a manner that irritates other
drivers to get good mileage. (This was a general response to many
posts and a few other threads... not just the previous poster).

I filled the tank (and reset the computer) last night and drove about 40
miles around town today, to work, to the dentist, back to work, and
home. The 5% generous computer is indicating 61 MPG tonight. This
included 70 MPH interstate where I didn't always drive 70, but
everywhere else drove at or above the posted speed limits.
My usual commute is 10 miles in 25 minutes on slow roads for about 52
MPG average. Today's longer trips more than countered the high speed

I am using the car's computer to determine my "overall" average over a
number of tankfuls, the more the better. That figure is generally in the
low to mid 40's in the winter and upper 40's in the summer. I don't reset
it very often, maybe seasonally or if I'm dusting off the LCD screen and
accidentally press the reset button.
It seems that in a lot of cases people are reporting their "per trip"
averages. In those cases, I do see higher numbers, but I don't consider
that a useful figure. The MPG averaged over multiple tankfuls is a more
accurate representation of the actual fuel efficiency. If I reset the
computer for every trip, I would probably see the higher numbers people are
When it comes to driving style, I don't use extreme foot techniques, but I
do coast to stop lights and try to maintain the pulse-and-glide method, so I
am conscious of the things that are needed to increase efficiency.
Pulse-and-glide is difficult on Route 1 in the Princeton, NJ business
corridor during the morning commute, though. I still maintain that the
biggest hit to long term average efficiency is the cold temperatures,
especially considering that the car is kept outside at night. In the
summer, even with the AC running at all times, the mileage goes up. For me
the other big hit is that the majority of my driving is shorter trips.
Perhaps "summer gas" vs. "winter gas" has an effect, too, although I'm not
clear on that.

But people are obsessed with and/or caught up in reporting large
numbers, in some sort of dick size contest, so they report the mileage
figure given on screen in that last mile and a half home, downhill, from
the gas station where they just filled up and reset the meter.

My sentiments exactly. There's a reason why Consumer Reports says
real world mileage is 44 mpg give or take. Given that, I'm satisfied
getting 45.8 mpg lifetime. No need to obsess about it or drive like
like a dillweed. Be happy - you're getting better mileage than most
everyone out there who's not on a bicycle.
