I'm offended!

What would he call my '82 'n '83 junkers? Scrap???

1. 2008 - 1993 = 15. see my earlier comment about your math.

2. you don't seem to understand that modern cars are much heavier than
the older ones, and thus, because the extra weight takes more energy to
move around, many modern cars lose their fuel efficiency advantage
compared to older ones. or at least, older hondas. a literally 20 year
old crx hf can out-perform the current civic hybrid by some margin in
fuel economy ratings.

15 years old junker or 20 years old junker - what is really the difference?

I was never comparing her 93 to todays 2008 models but I was comparing her
93 now with 185k miles to *the same car* when young, with 10k miles in 1993.
Do you really think her 93 with 185k burns less fuel than when it had 10k miles
on the odometer? I certainly doubt it.

It does if you want to extract city mpg from highway mpg.
If you take too much data into the average you will blurr
the difference between city/highway mileage and for some
cars it makes a huge difference.

It introduces some problems, too...

You really don't know much do you?

A car with 10K on it will almost always be less fuel efficient than one
with 50K or more...

<sigh>

spot data is not average data. spot data is used to compile average data.

eh? you don't seem to have a very good grasp of math principles. but
the education system today is not very effective so it's probably not
your fault.

the "difference" is that you don't know what you're talking about.

yes i do - at 10k, the motor is still tight and thus wastes more energy
on friction.

You should use data of the same kind when compiling average.
If you mix city mileage and highway mileage you will not get
either calculation improved by using average. You will get pretty
useless mixture/average of mileage changing in time with
no chanse of spoting the cause for increase/decrease.

Are you trying to compensate some of your own education problems
with childish coments like this one?

Really? So the best days for a car start when the warranty ends :-))
Show me the source of your information about 50k, Master!

Only if you drive a yugo. Most cars come a warranty that is a bit
longer than 10K miles.

that's spot data!!! it's spot data that comprises an average. [and
there's two t's in "spotting", two c's in "chance".]

spot data is is essential to acquire, but seems you don't understand the
concept of interpretation.

education problems? [two m's in "comments", and your computer has a
spell checker.] no, i don't think i have education problems. i have a
problem with idiots that can't do math [or spell] though.

You expect somebody who was incapable of operating a web browser and visiting
google in the first place to be able to use it now?
You need to give him a search string. Obviously, he can't do it by himself.
