EPA didn't test cars before 1984 so yeah, the estimates will be off. I divide 300 (the normal range for a car) by the tank size in gallons to figure out the manufacturer's approximate MPG estimate.
My 1965 truck has a ~20 gallon tank, so that would peg it at ~15mpg, which is correct.
My Rabbit has a 10.5 gallon tank which would put it at ~29mpg, about right on 87 octane.

I had a ford f250 extended body with the straight 8 in it, got 9mpg no matter how I drove.
I had a supercharged tacoma with the v6, 18mpg no matter what. 16 mpg towing.

What year F-250 had a straight 8? I'm not aware of Ford ever making a straight 8.

Confirmed: Wikepedia says:
"Ford never adopted the straight-8, using V8 engines in their entry-level cars and V8 or V12 engines in their Lincoln luxury cars from the 1930s on."
However, I googled "Ford straight 8" and found this:
How About A Straight-Eight-Powered Ford Tempo? T-Drive!
Admittedly not a production engine but interesting anyway.

You can get numbers back to 1978.
Download Fuel Economy Data
This a reply I got on another site in regards to my '81 Datsun ratings from there.
"An approximate conversion... 22.5mpg CAFE=17mpg 2008 estimates, 20.5mpg CAFE=15mpg 2008 estimates, and 26mpg CAFE=19mpg 2008 estimates. So I guess using the 2008 estimates, your car is rated at 15mpg city, 19mpg hwy and 17mpg combined. "
Is this conversion (old ratings multiplied by 0.75) reasonable?
Sven7, your method gives a result of 14mpg for my Datsun, 20% lower than the 17mpg above.

When I'm driving in the city it's a 1.5 mile drive (or less) and usually has about 15 stop lights. I'm pretty happy when I can manage 25 mpg doing this although I'm usually closer to about 22. It doesn't help with it being colder and it really doesn't help that this town is built on a hill so I'm either fighting to go up hill or coasting too fast.

I'm just wondering why to get into the car to drive 2 miles or less? I live about 2 miles from train station, and my work is another 2 miles from train station in Warsaw (20 miles on a train). And it's less than 10 minutes to get to the train station or to work with a bicycle or 20 minutes on foot. If we're talking of 2 miles trip with 15 stop lights, I'm sure I would go faster with a bicycle. And I'm passing many of my neighbours in their shiny cars, with my crappy bicycle on the way to the train station, even if there are just two stop lights on the way. Faster, healthier and definitely more FE friendly
Just a thought ;-)
