What is the gas mileage for a 1975 ford thunderbird? 460cu eng.
well reset you odometer and divide the # of miles gone on a whole tank by how many gallons the tank
In laws had one, they were getting just over 13 on the highway but it dropped to 8 in town in the summer but came up to 9 in the cooler days, most likely it was the A/C in the summer, the A/C didn't seem to bother the highway mileage. Man what car, just hop in and float to wherever you wanted to go, that hood looked like to would go on forever. Working on that was dream compaired to today's vehicles, you open the and you say engine, and a lot of it too, 460 in a car.
EPA charts don't go back that far but Cougar with same 460 got 8-10 city and 13-14 highway
It may be helpful for others but a 390 motor can get 24 in UK gallons thats about 21 US, trying hard on the motorways in France at 45 mph I got 27 UK MPG ( 23 US)
my dad had a big 4 door ford company car with a 46o. was like a 76 or 77 but you could literally see the gas guage go down when he stood on it
