My Grandfather told me, "More horses eat more hay". May still be true
in some cases, but take a look at how horsepower has also increased
over the years. I had a '95 Chevy Silverado with a 5.0L V-8 that
pushed out 175 HP +/-. The new Silverado has a 5.3L V-8 that pushes
300+, and get better mileage. Mike

I love the article I read that someone wrote about how bad mileage
progress has been through the years. In it he compares the mileage
his
current vehicle gets with the mileage that a Model T gets. Then asks
why
it hasn't improved a LOT with all the technology.
Anyone with a brain can read through it and see that the mans "logic"
is
VERY flawed. BUT that doesn't stop the tree huggers from proclaiming
it
a holy writ.
