[sustainable sam]

Just wanted to introduce myself. I am very interested in fuel efficiency and sustainability. Of course I would prefer to be driving a hybrid but this is what I have right now, so I am trying to make the best of it. The vehicle is a 1992 Ford Taurus Wagon (I will post pics once my post count is up). As you can see I have been averaging 24.77 mpg on a fairly similar commute.

I am going to be driving about 80 miles per day 5-6 days per week so I figured I would see if anyone had any specific suggestions for me. My route is almost all highway and has a few really large up and downs. I have taken off the rear mudflaps and will be taking off the fronts tomorrow, along with the roof rack. I am considering the purchase of an MPGuino so that I will be better able to monitor my habits as this car doesn't even have a tachometer.

Anyone have any suggestions where I should begin? THANKS!
