Hey guys,

I have a '07 V-6 Stang with the Pony Package, manual transmission, around 17500 miles. I am getting pretty decent fuel mileage now that I made sure the tires were filled to specs, but I am still hunting for better fuel mileage. I use the cruise control religiously and when I'm not in a hurry I shift at the recommended speeds in the owner's manual. The air filter was replaced when I took my car in for the 15,000 mile inspection.

My question is, are there any easy addon parts/accessories I can do to my Mustang to get a couple more MPG out of it? What about these K & N air filters? Or some sort of cold air intake? Or a tune? What's something that a novice mechanic can do to this car to get some better fuel economy out of it? I've done all I can on the driving end, so now I need to examine mechanical upgrades.

Thanks in advance!

intake and tune.
the problem with that is , its so much fun the weight of your right foot counters any gain in MPG.

eh, if you're already driving in a conservative manner, you're not really going to find a way to greatly improve gas mileage. Even with a CAI and tune, it's pretty marginal. I gained about 1.5 more MPG per gallon with the CAI adn 91 tune. I guess that's allright, about 17-20 more miles more per tank. Nothing spectacular, but I guess with gas prices nowadays, any little improvement is what it is.

Weight reductions might help a tiny bit.

Underdrive pulleys and an aluminum driveshaft will help save fuel, but the savings are offset by costs. Also after the problems I had on my 02 mustang with udp's I am wary of replacing major engine or drivetrain components.

One other thing, don't get heavier rims and tires, that will VERY quickly offset any mileage gains due to higher rotational mass, it will also hurt stopping distance, and performance.

The cure for the lead foot.

Otherwise, you won't gain much unless you do some extreme work, which in the long run, is not worth the time or money.

A lot of bolt on mods will give you better MPGs, but for the price you pay for the parts, you are better off just buying gas. The only thing I could think of is, when you are replacing your air filter next time, go for a K&N direct replacement filter.

I'd like to see some test results on highway mpg with/without chin spoiler. I don't know what the coefficient of drag is on the stangs but I don't believe it to be low. I hope it's below .40 but that front end is like a plow. I do have to agree that you can't cost benefit any mod with fuel savings as the payback. These aren't economy cars. If you want performance and economy, the Lotus is awesome but does cost a few $$ more. Or, you can try the new Accord coupe.

Check out VMPtuning and get a CAI/Tune with his 87 mileage tune, it may take some time to make up the $600 bucks for the CAI/Tune, but it will help mileage, performance, and be a great mod.

A simple experiment that doesn't require any work to your car: Don't fill up at the station, buy smaller amounts of fuel at a time. Gas weighs about 6.2 lbs per gallon. If our tanks hold 15 gallons, thats about 93 lbs. If you only drive with half a tank or less at all times, thats about 46.5 pounds thats no longer dragging behind you like a boat anchor. It will probably be a marginal difference, and I don't pay much attention to mileage, but I do notice that my car takes off like a bat out of hell when the tank is almost empty...it definitely doesn't have to strain as hard. Every little bit helps...
