A Classic Car is defined as one which is over 25-years-old or one whose line has been discontinued. Thus, the Ford Pinto is now a Classic, as is the Chevy Vega. However, neither of those could be considered as having the worst gas mileage, not by a long shot. Of course, there are specialty cars such as the Lamborghini and the Rolls Royce that get bad gas mileage, but you also must consider these cars were not the norm for their day. In finding which Classic Cars get the worst mileage, I’d have to narrow the field to only standard production cars that were readily available and affordable to the public rather than the select few millionaires (who are now considered almost middle-class by today’s standards). The early 60’s were the age of the huge car with the monster motors. The Chevy Impala, the FE-Series Fords like the Galaxie were two top sellers. I have a 1963 Ford Galaxie 500 XL that I picked up in the 70’s for $350. After I restored, painted and installed a new engine, it was ready for the road. Weighing in at 4500+ lbs, it is powered by a 406 cubic inch engine that is topped by a Holley 4-barrel carburetor. With a nodular rear with limited-slip gears and a 4-speed gearbox, this monster tops out at 120 mph on a straight road with no cops and a headwind. When I bought my first 1963 Galaxie in 1972, gas was $.36 a gallon and it took $6 whole dollars to fill the tank. Just out of school and still working at McDonalds, I recall scraping for dimes in the bottom of my purse to get a gallon of gas so I could drive home that night. Today, it would cost $54 to fill that same tank. My current Galaxie doesn’t get much better mileage than the first one, which had a 390 cubic inch Thunderbird engine. That one was also a convertible and was a few hundred pounds lighter than this one. I made the mistake once, of doing a mileage check on my Galaxie. I took the mileage test when I had to drive it to work every day for a week, and I learned my lesson the hard way. I found those 400 horses were very hungry. It got 6 miles to the gallon and that WAS highway mileage. I drove it to a car show once and it took a quarter tank each way for a 45 minute drive.
