Gas mileage question

First of all i know this maybe the wrong place to post this. I have looked for a vehicle specific section but couldn't find one for the old Ford Fairmont.

I just purchased a beautiful 1980 Ford Fairmont. It has been garaged for the past 10 years and it is awesome condition with 53k miles. I am just wondering what kind of gas mileage is normal for this vehicle. I know it's not going to get anything great i am just worried if there is a problem. I have only drove about 100 miles and got 12 mpg with 95% highway driving.

Before running it i changed the distributor cap, rotor, plugs and wires, fuel filter, and changed all the fluids. When i brought it home it was trailered. As i was running it in the garage i got lucky and it ran out of gas so i didn't have any old gas in the tank. It was filled with a full tank of fresh gas.

The engine is the 200 inline 6 with i believe the C-4 tranny not 100% sure on that though. I'm not worried about the gas mileage obviously this isn't a daily driver. I am just trying to figure out if there is a problem with something. I assumed a 6 cylinder would do better then 12mpg highway.

One other thing what do you think this car is worth? I'm hoping i got a decent deal on it...

Thank you

Are you sure your math is correct? That is truly terrible.

Re: Gas mileage question

I think so i put some gas in to make it down to the store. According to my logbook i then filled it up with an additional 13.107 gallons. The odometer at that time was at 52,941. I then drove almost all highway miles and refilled at 53,039 which would be 98 miles drove on that tank. It took 7.86 gallons to refill the tank after driving that 98 mies. Which if i figured it right would equal 12.46 miles per gallon.

Re: Gas mileage question

The inline 6 in my '90 F-150 gets about 17 mpg. I used to have a Fairmount Futura with a 302. I don't remember the mpg's, but I'm sure it got more than 12 mpg.

Re: Gas mileage question

The old Fairmont may have it's brakes sticking on and not fully releasing. So the engine can over come the brakes but your pushing a car that is wanting to stop. Or it could be that the tranny is slipping causing the engine to rev highly and burn alot of fuel. Or maybe it's that carb is just dumping alot of fuel into the engine. Fairmonts with the auto (the only one is the C4 three speed) could get over 24 mpg in good trim. It depends on what rear end ratio your car has, and the tune it's in: good/bad. Obviously you have one, two or all three of these at work causing you to get poor mileage.

These cars don't have a big following as they were more transportation devices than love affair cars for families. So, the value is in the eye of the beholder. I like them, and have had a few four eyed Fox bodies in my time. Heck, the Bullitt I own is a SN-95 body which is nothing more than a highly updated Fox. If you like it, keep it. But don't expect to get a return on a big monetary investment in this little sedan. Fix it up to drive and be happy with it. Car and Driver referred to the Fairmont as Ford's Volvo long before Ford bought Volvo...

Re: Gas mileage question

Try running half a tank of 89 or 91 octane gas and see if that improves mileage any. Be sure that you have no fluid leaks of any kind. Whenyou say you changed all the fluids did you also change out the differential oil and inspect the gears? You might want to change the spark plugs again since you ran the plugs on the old unstable fuel. Fill up, run it for a good five minutes and then change out the plugs and see if that makes a difference. Old/bad /dirty fuel can foul plugs!
