[Vwdiesel] High fuel mileage

[Shirley, Mark R]

The problem is, most people don't understand engines and fuel conversion
efficiency.
You can very simply work out how much energy it takes to move down the
road at a given
speed, within a few percentage points, and how that relates back to a
given amount
of fuel to get rough fuel economy, yet that doesn't stop people like my
neighbor, who
claims there's a warehouse up in Lansing that has hundreds of 70mpg
carburators in it, 
that the oil companies bought to keep out of the publics hands.  The
reality of trying
to explain to him that it can't work and how much i'd have to do to
prove it keeps me
from contradicting him.

The only way the fella with the cummins would suddenly get 40mpg was if
the btu content
of the biodiesel was 2X as much as dino diesel, and we know that isn't
true....  :)

A friends' wife's dad has a 2wd Cummins truck, and she claims he's
getting high 20's, but
I think thats mostly due to his driving 40mph down country roads all the
time.
