Civic fuel consumption, again
 

Is anyone keeping an accurate record of fuel consumption in their 2006 model
Civic?

My fuel consumption is way off the mark and I'm wondering if there is
something wrong or if the fuel mileage of the '06 Civic really is that much
worse than advertised.

Perhaps it's the damn city traffic.

Anyway, just want to compare notes.

Steve

A) yeah, city traffic can be brutal to mileage, especially if you punch it
when the light turns green.

B) do you have enough miles on it to start being concerned with mileage?
Typically it's not fully broken in till around 10K.

EPA mileage estimates are determined through dynamometer testing in a
laboratory, and among the factors reducing actual gas mileage that are not
considered in these tests are rolling resistance of unpowered wheels/tires,
aerodynamic drag, non-productive operation (engine running with no forward
progress, as occurs at traffic controls or in stop-and-go traffic), ambient
temperature (affecting intake air density), and altitude (also affecting
intake air density). City and Highway mileage ratings determined in the
laboratory are adjusted downward by 10 and 22 percent, respectively, in an
attempt to compensate for these and other factors, but Consumer Reports have
consistently determined, using their own mileage testing protocol, that the
EPA mileage estimates posted by automakers for new vehicles are optimistic,
sometimes by as much as 30-40 percent.

And yet, my '93 Accord consistently got 10-20% above EPA estimates on the
highway. Go figure.

This may seem like an asinine question, but what is your process for
calculating actual fuel mileage? Also, what is the elevation and range of
mean daytime temperatures where you live? I ask the latter because lower
elevations and lower mean ambient temperatures, in comparison to the
location of the automaker's test facility, will result in comparative
mileage improvements, ceteris paribus, due to more dense fuel/air mixtures
prior to combustion.
