how can I improve the gas mileage of a 2007 Mustang G?T ? will it be better after the break in period?

Answer 1

I used to drive a 2000 Mustang GT and I replaced the air filter with a K&N. It increased the horsepower and the gas mileage.

Answer 2

Fuel economy will get better after the break in periode. Search the web for propor break in proccedure, or ask your Ford dealer. Driving light footed will take the engine longer to "break in".

Keep tires properly inflated.

Don't carry things unnecessarily, weighing down the car will waste fuel.

Having larger tires than what the car came with will decrease fuel economy.

Front wheel alignment. If the alignment is off, the car will have more rolling resistance.

Synthetic engine oil ( using the proper grade)reduces internal engine friction and helps marginally, with power and economy.

Change the oil regularly. If it looks black on the dipstick, its dirty, change it, and don't forget the filter too. Using synthetic oil doesn't mean it can stay in the engine longer, it gets dirty just as fast as regular oil.

Spark plugs...Platinum or iridium tipped spark plugs work better.

Ignition wires, distributor cap and rotor should be regularly replaced. This reduces the electrical resistance of these components and gets more spark to the spark plug.

Engine coolant should have the proper mixture. Having too much coolant / water mixture causes the water pump to work harder.

The oxygen sensors do need to be replaced after a certain amount of driving. I would recommend 60,000 mi ( 100,000km ).

And finally...
The Mustang is not known for fuel economy. If fuel economy is your biggest concern??? I would start looking into something a little smaller, lighter. These beasts are not known for fuel economy. But they sure look cool.

Answer 3

the gas milage typically does improve a small amount after the car is fully broken in. Maybe by 1mpg ir so. Really the best thing you can do is to drive like you don't want to spill an open glass of water in your cup holder. Driving fast and accelerating fast use up the most gas. IF you go 65 on the highway , keep your rpms down and accelerate slowly you will get the best milage. There isn't much else that you can do in terms of modifying the car.

Answer 4

You didn't say what mileage you're getting.
My 2004 GT gets 19 mpg but it has a cold air intake installed. I was getting 20 mpg with 5w30 motor oil but it's hot here in Texas so I switched to 10w30 for a little better protection and dropped one mpg. Did the same on my F150.
I also check my tires monthly and make sure they are 2psi below the rating on the sidewall (when cold).

P.S. I only use synthetic lubricants in my vehicles.
I change the filter every 5000 miles and change the oil every 10,000.
My 83 T-Bird has over 150,000 miles on it and still runs strong.

Answer 5

My GT did, by about a mile or two. Just keep your foot off the accelerator. That was my problem, I loved to hear that engine roar, but you pay for it. I also kept my tire pressure 2# below the max rating on the tire. 42# as I recall. This will make your ride a little rougher but you can save a little on the gas.

Answer 6

get an SCT Tune And a cold air intake.
