OK so I was just getting right around 180 miles to a full tank in the city.. now im a very spirted driver (damn NASA racing ) but i just thought that the new mustangs sucked monkey nuts when it came to good gas MPG.... but i recently did my 10000 mile tune up and decided since I was under the car I would change the fuel filter.. and WOW im glad i did, that thing looked like it was draggd in mud ...I did a complete fuel system flush and new filter changed all my fluids out with RP and HOLY ****ZZZAA ! 240 in the city with very spirted driving . And this whole time i though my tune just sucked ! Its always the simple things we forget to check ! Just thought I would share my NOOB moment !
