Ideas for better gas mileage?


How good of gas mileage does a 4 cyl Mustang get by the way?
 
As far as keeping your foot out of it I FOund with my truck it only varies about a half mile to the gallon no matter how I drive. These new vehicles are a lot different then the old school cars with holley 4 barrels that had secondarys that did make a differnce on how you drove it .
 
Well i've really never noticed the milage, except when i first got it but then i filled her up and went about 85 miles on a 1/4 tank and thats mixed highway/city driving. NOW i get not so good cause the damn ruber seal around the filler neck and the gas tank leaks like a biotch Everytime i get ready to fix it and drive the 5.0 it starts raining But still i bet it does wayyyy better then a f-150. I go about 2 weeks and a day on a somewhat of a full tank in the 4 banger and only about a week if that in the 5.0 peace

The CAI and programmer make sense but not sure about the catback improving gas mileage.

I agree. There really does not seem to be a real good way to do better. You may see a little better mileage from a catback, but more than anything you will like the sound.

I get about 14 mpg. Its about as good as it gets with the 05. I have not done any mods because of the Vette and the house get all my money now. Mostly the house.
 

agreed...

As for the cat back, think of the engine as a large air pump. Whenever you increase the efficiency of the airflow you see benefits i.e. more horsepower which in turn means your truck will work less to move its weight. Its the same thing with the CAI...You may not see much fuel economy benefit, but some for sure.
