I feel sorry for you. The 2002 Blazer we have has 4X4, 4.3 V-6 engine
and will get over 25 on the highway with no problem.
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.
