does anybody know what the gas mileage of a 79 lincoln town car is? both city and highway. l looked but could not find it anywhere.

Highway around 16 city around 9 miles per gallon

A 1979 Town Car is equipped with a 2bbl 400 CID engine rather than the massive 460 of the years before. It got closer to 12 city and 18 Highway, mainly because emission controls were not as stringent as they are today. You might be amazed at the mileage cars got throughout the 80 is and early 90's. In use your mileage may vary because of the age of the car.
