ok I know since I own a mustang I shouldn't really care about mpg's but 13 mi. a gallon seems a bit off on my car and kinda rough on the billfold since schools is about 12 miles from the house. what have some of y'all done to help gas mileage

 

well first off how hard do you run it.and i get around 20 to 22 mpgs and i can get about 260 miles out of a tank.

 

not too bad every now and again I guess.The only time I ever got 20 miles to the gallon was when I went on a 200 mi. trip to Fla.

 

Doing alot of idling will kill your mileage. If I fart around in the garage with mine a lot it only gets about 11 or 12mpg. If I drive it only it will get 17 to 21mpg.

 

I get in it,drive 11 miles with 2 stop signs and then another mile or so in town to get to school

 

I drive all city and get around 16.5mpg driving moderately. But this is with a NEW mostly stock 5.0 motor. But my S/C Mustang gets around 12.5mpg no matter how I drive. I know adding a cam and a stall decreased my mpg from 15mpg to 13mpg, so the cam could be a possible factor.

 

how fast do you go? with your mods I can see 13mpg...

in my stock 5.0 city I get ~17mpg

 

a little while ago I went and checked what my trip said;119 at right under half a tank so tell me what yall think

 

while i'm headed to school I'll vary speeds from 55 to 65 but usually 60

 

You need to fill it up and reset the trip meter. Drive it to about 1/4 tank and refill it. Devide the miles you drove by the gallons you put in. It only holds about 15.6 gallons I believe. So if your gauge is correct, probably not exact, that is 119/7.5= 15.86mpg.
