ok so i have a 2000 mustang and ive had it for about one year. ever since then i have been getting terrible gas mileage. i just swaped out three of four callipers that were making my brakes drag as well as the two front hoses i also swaped out o2 sensors and got new catalytic converters also a full tune up and am still having preety bad gas mileage any suggestions as to what it could be. i have had it tested for vaccume leaks as well as a fuel pressure test anything will help

how bad? Have you actually calculated what you are getting?

what are you getting per gallon?

Fascinating!!!
Yeah. Post the mileage you're getting.

This one time, my filler neck gasket rotted out, and I was getting piss poor mileage because all my fuel was pouring onto the road while I was driving.

i am getting about 13.5 mostly city driving is it normal, and the filler neck gasket was replaced already before doing most of the work done

and i have actually gone up from 10 mpg's and ive done my calculations multiple times another thing that ihadent factored is that i do a lot of short driving waround sisnce i only live about three minutes from my work. i start up my car about 6 to 8 times a day could that be another thing affecting
