Are there any mods that can help my 2009 V6 with mpg performance? My generation of Mustangs get's really terrible MPG, and as much as I am forced to travel each day between work and school... It would really help me.

I was thinking a chip perhaps that adds a bit more HP, and in about a year or so it would pay for itself... but a chip would void my warranty, and I dont really know if its worth the risk. Are there any less risque options?

 

Why not do a tuner? If you need to have the vehicle serviced just return it back to stock settings.

 

What kind of milage are you getting? I don't belive a tune will make a huge difference IMHO

 

Just avoid stepping on it.
My 4.0 gets about the same as my 4.6 GT.
Sometimes less, I think because it is an auto.
When I bought it the computer had never been reset since new(10K mi.).
It read 19MPG.
It was grandma owned.
I usually get about 16 in mostly city driving.
My GT usually gets 18-20 overall, but with less city driving.(Going easy I've hit 27 on a 100mi. cruise)

 

You can contact Justin at VMPtuning.com. He will write you a tune for MPG plus give you a little more power. You can call him or order a tune for your car online. You will have to buy a tuner and the tunes, so you are looking at $500. if you want an intake also he has package deals. I got 22mpg with his tune on my car when I was N/A with 3:73 gears. It would pay for itself in a year. Doing this is about the only way you will see a good jump in MPG, besides good driving. I currently get 19 mpg from my supercharged 4:10 geared v6. (VMP TUNE)

The tuner will not void the factory warranty, you could have a hassle, depending on where you bought the car. A good dealer will not give you a hassle unless you are hammering the car, and that would show.

 

Wow, I chcked out the website they have these on sale:

Even though I don't care about MPGs, at this price I might get a performance upgrade.

 

BOSS 244 already mentioned what I was gonna say... get a tuner, contact a reputable programmer/tuner and get a tune for MPG, easy sneezy! And... lay off the gas!

 

Check out the coil thread.

Some forum members claim gains in MPG from switching the Granatelli or Screamin' Demon coils and zero ohm spark plug wires.

 

With any modifications like this, you'll have to weigh the cost of the mods vs the money saved in gas. Unless you were replacing some parts anyways (like going with low rolling resistance tires) spending hundreds or thousands of dollars in mods will take years to recoup the savings in better mpg, if ever. In other words, if you spend $300-400 for a tuner and custom tunes, to get 2 mpg better gas mileage, how long will it take you to recover that $300-400 you spent with better mpg given the amount of miles you put on the car.

 

just drive it nicer. best mod to date. I can get 31 mpg out of my 08 shelby gt, 32 out of my 06-09 mustang gts and my 06 was a vert.

 

+1 on the driver mod. You can make a real difference simply by adjusting the nut behind the wheel.

 

Easiest mod you can do to your V6 Stang to get better gas mileage only cost a dollar at most gas stations.

Inflate your tires to 34psi. You will see a noticeable yet slight increase in fuel economy. the higher tire pressure means less rolling resistance and tire deformation (IE less friction) so your car rolls easier.

 

i agree. make sure your car is tuned up with good plugs and clean filters and fluids. ive got a boatload of mods and run 93 octane with a street race tune. i keep my foot in it pretty good and get 22-23 around town and 26-28 on the highway. all the mod parts say better mileage, but dont buy into that. i will say i get alot better mileage off the 93 than the 87 but then it costs a little more too, and i`m tuned for it. check to see if your fuel contains ethanol. try to find a station that does not.

 

I just checked my fuel mileage over the last two weeks, I have a 48 mile one way trip to work, alot of 55mph driving on 2 lane roads, been getting 22.3 mpg with the exact same setup I run 12.31, 12.38's with. DR's n all.

 

not bad at all, and nice times too. all that fun and still great mileage. gotta love these 6ix`s

 

Dual exhaust helps, along with a cold air induction kit and a tune. I average 31 mpg on the highway.

 

Your driving habits really make the most difference. I've had my 2010 V6 for about 6 months now and my worst tank of gas was 21.1 MPG, and my best (all highway) has been 28.5 MPG. On average, I typically get 23-24... My car is completely stock except a muffler from a 2006 GT.

 

coast more.

so many people stay on the gas all the way up to the point they want to slow down, then go directly to the brake pedal... by coasting more you'll save on gas and your brakes. I routinely get 4 mpg more than my wife IN THE SAME CAR just because of our different driving styles.

 

Yeah, and don't floor it off every light like I do.
(Actually I am pretty good at coasting too, but the rest of my driving style negates the savings.)

 

Swap out the v-6 muffler for a gt take off. takes about 20 min tops Back when gas was close to 4 bucks a gal this mod paid for itself in a few weeks. That and swapping the stock air filter for an air grabber filter, were the best mpg mods i put on my 08
