Im driving a stock 2010 v6. I dont know much about cars. I know I can make the car lighter and make sure tires are properly inflated. Are there any mechanical parts I can install to improve fuel efficiency?

Thank you for your time.

no, not really. your driving style is the biggest factor in fuel economy.

And the 4.0v6 is kind of a gas hog, in the scheme of V6's

If you are running the stock muffler you could change it to a GT or something freer flowing, I picked up 2 MPG when I did that to mine. Tuner and JLT CAI helped by another mile or 2. My 2010 was getting over 27 MPG with 70%highway 30% city and would get close to 30 MPG all highway.

I had a V6 4.0 2007 What I did is invest in a CAI "cold air intake" and get a tuner with an 87 octane tune for better gas mileage. I think I did fairly well, it put me in the 30mpg range. I also have a good friend who has a V6 4.0 2010. He just went up to the show in Michigan, he bought one of the CAI that do not require a tune he told me he got about 29 mpg for the trip. I think those CAI without tunes are kinda hit and miss though.
Also how you drive the car can effect your gas mileage as well, I just drove 1600 mile round trip in my new 2014 GT/CS and I got about 21 mpg. I was actually pretty happy with it!

Spending $500-$600 on a CAI & tune to get MAYBE 1-2 mpg gain; assuming you don't get on it which is asinine because you bought the car for it's fast appearance and not economy; is pretty stupid. Over the life of the car you won't likely break even.

You want to save gas? Walk more. Drive like a granny.

Want to save money to SPEND on gas? Drink water, not soda. Make your own coffee, not buy Starbucks. Pack your own lunch, not buy Happy Meals and buckets of chicken.

We're a stupid society. Save money elsewhere but spend it on what you love and paid $30k or so for... YOUR CAR.

You have a Mustang and you want to save on gas? Well, you could sell it and get a Fusion.

Fuel economy improvement is no secret. There must be millions of threads, articles and news stories on this very matter.

how can i save gas should never appear in a mustang forum.....If you bought a sport car and your worrying about gas mileage then your doing it all wrong.

I've read on other forums that the Prius gets good mpg. I wouldn't know since I've got a mustang.

this. you aren't going to get 1-2 mpg from a muffler or CAI. Even on the highway you're driving around with the throttle barely cracked open; the pumping losses in the throttle body are so huge that any restriction from the exhaust or intake ducts can be pretty much ignored.
