REPLY: Did you take into account that I drove from Effingham to Tower
Hill to Shelbyville to Tower Hill to Shelbyville before heading home
to Lake Villa, Il ? Unless you can prove the Average MPG real-time
bogus on my car as well as the other Posters confirmation on his 29
average MPG, its best to remain quiet Dad for youre looking
frustrated. Finally, can you tell us why you dont want God to exist
in your personal life ? Thank you much.

Not what you said, here's a reminder....."REPLY: Theres no need to do
math ; the DIC gives you the Average MPG for the gasoline youve
consumed in real time . I havent re-filled the tank since i got home
but i filled her up in Effingham, Il and drove
to Lake Villa, Il on 3/4 tank of gas. Dont know exactly now far
that is, but, like i said...the DIC computes the Average MPG as you
are driving. "

I'm sure your God is somewhat against lying but how would you know
that? Disappointed, naw, you're performing down to you normal level,
pond scum.

I commute in my '00 C5. When my coworkers see it, the first thing
they say is, "How can you afford all that gas?!?" Everyone seems to
think it gets 10MPG or something. They're floored when I tell them
that I average 28MPG and could do better if I wanted.

Next think I ask is, "So what do you get in your Camry?"

"20mpg..."

So, who drives the economy car?

On any trip, over easy terrain, the cruise
control in either my C4 or C5 will beat the EPA
estimates by a couple of miles per gallon.
(calculated) Same has held true for each of
mama's sedans but not my truck (I think GMC
tested it running downwind).

The L98 computer is somewhat crude and has some
sweet spots and some sour spots speed-wise. (ex:
70-75 gets better mpg than 65).

Dyno-tuning the C5 knocked the cruise control
mileage down a bit but, it still beats the EPA
highway on long level runs at 65 and 70.

Cruise control-OFF is a different matter. Being
well beyond 70 y.o. is an advantage when it
comes to mpg. :|

My own experience on a recently completed trip in my 2004 A4 Coupe from
Seattle to Reno to Las Vegas to Salt Lake City then back to Seattle netted
an average of 28.2 MPG. This is based upon the info provided from the the
onboard computer, not "real-life" measures. At the beginning of each day I
reset the Averge MPG back to 00.0. The first day of my trip from Seattle to
Yreka, California netted me my highest daily averge of 29.4 MPG. Whenever
possible I used cruise control set to posted speed limits (give or take 1-5
MPH).

Although not scientific, I was extremely surprised and pleased with the
economical performance of my car.

Did I mention the stretches between Reno and Las Vegas where I would punch
it up to 110-120 MPH for short bursts of fun? :-)

When driven sanely, most all C5's and C6's will produce gas mileage numbers
that compare favorably to lots of cars thought of by the public as
"economical". I am always happy to tell others that my car can be added to
that same "economical" class ... and then speed away!

And 19.3 on trips.

From that same site, in a nutshell the MPG est. are adjusted down after
the test numbers are in.

See excerpt below from http://www.epa.gov/fueleconomy/420f04053.htm

After the vehicles have been tested, the results are adjusted downward
to account for conditions that occur on the road that can affect fuel
economy which don't occur during laboratory testing, such as cold
temperature, aggressive driving, excessive use of power-hungry
accessories, among others. The city is adjusted downward by 10 percent,
and the highway by 22 percent.
The equation for calculating the city or highway average fuel economy,
given in miles per gallon (mpg), is:

Kind of late getting into this thread...

To be honest I do not think the instand or overall milage that the
cars computer is any more accurate then trying to level brickwork with
your eyeballs as you are laying the bricks...

BUT I will guareentee you that my C5 6 speed ragtop will get at least
30 mpg over a 400 mile trip (only stopping at a few rest areas) down
Rt 81 ..done that more then a few times and I normally set the crusie
control at 82 mph and still pry that I do not get runover ...

This is actually filling the tank...then entering directly onto 81
driving 400 or so miles then actuallly filling the tank again...Then
doing the math with a pencil and a piece of paper...

The on board computer's calculations are only as good as the data it has
to work with. If you are coasting and the computer is showing 70 MPG and
you reset it's calculations then it will immediately register 70 MPG. We
all know, however, we're not really averaging 70 MPG but we are - for
that short period of time given that small and non representative data
set. If you then punch it and a couple of 10 MPG figures come in it'll
average out around 40-50 MPG. It's only over time that the averages
start settling down. Over many months I've settled down to around 21.1 MPG.

BTW: Why is it that the maximum number you can get is 70 MPG? Previous
models went up to 99 MPG IIRC.
