On my green 68 Sedan, the mileage will be in the 12-13 mpg range if I drive in the 75-90 mph range, and about 14 if I drive 65-70. Since its going to suck the gas anyway, I drive it faster. My 68 LeBaron may be more sensitive to speed. I only own it for a few months so I don't know for sure. Also, it has a lock up torque converter which will improve transmission efficiency at low speeds, especially while accelerating or going up hill... D^2
