MPG

Discussion in '2002 - 2005 Ford Thunderbird' started by jimtcrowe, Apr 17, 2017.

  1. So I ran into a fellow Thunderbird owner yesterday of a 2004. He told me his car got 28 to 30 mpg on the highway at 65 mph. He also told me it had 64 valves and it ran on 6 cylinders unless he got up to about 7o mph on the highway. (everything stock)

    I typically get around 17 mpg city and have gotten 21 mph on one highway trip. So how much of his story should I believe. :))))

    You should definitely replace your coils and spark plugs if you have not yet! You will get better performance.

  2. I took a trip from Bethany Beach, Delaware to Nags Head North Carolina & back last week & I got 25.5 miles to the gallon. I'm happy with my 2005. 77,000 miles on it with new spark plus & coils.

  4. well my best is 21 at 75 mph. So I guess I'm in line. I love the car so much I would have it no matter what the mpg, ha.

  5. July of 2008 I averaged 28-30mpg while driving mostly at 70 mph in my 2004 Bird w/ a passenger on a trip from So Cal to Bend, OR. Mpg was aided by Magnaflow mufflers and a K&N cold air induction install.

  7. I drive pressing the limits, passing and pretending I'm Sterling Moss. In one Bird I consistently get 28 mpg "on the road".
    When I got another two Birds, they only get 25.5 with that type of driving. It's depressing. It could be that in the first one I installed new "plugs" and changed out 5 coils. Don't know what it is, but it's definitely better in the one car.
     
  8. So, recent owner, how many valves does the V-8 have? Guessing 32. ??

    I've noticed people lie about their car's gas mileage. Probably the same guy lies about his penis size. Some guy on the Mustang Forums was telling people his 2012 305 HP V6 got 44 MPG on the interstate, totally impossible.

  10. JW in Dixie, yes, the V-8's in the retrobirds have 32 valves. 2 intake valves and 2 exhaust valves in each cylinder... :)
