What gas mileage are you getting?
I have a 23 mile round trip to work with about 50/50 highway/city. I get about 21.8. I recently took a 750 mile roady and got 26-28 with cruise set at 73mhp. I also don't drive like I stole it. haha. My car was totally stock until my new exhaust yesterday, now I don't know exactly what I'll get.
I drive 60 miles to work on the freeway, so with my K&N intake and FRPP muffler, I average about 28mph. When I'm just putzing around in the neighborhood, it's closer to 17. Also, I don't do any jackrabbit starts or burnouts, so that probably helps with mileage - and tires.
Glad I found this thread. When I bought my 08 a month ago I was not expecting much in the way of mileage, but I am getting a legitimate 19+ around town. Thought that was high, and actually started to wonder if it was running lean or something. I drive conservatively, but do occasionally like to hear the exhaust at high rpms. I am delighted!
you got a mustang, MPG shouldnt have been really high on the list when u were buying it. but on a more somber note, on a recent trip coming back from el paso. i averaged 26mpg @ 80-90mph on I-10 useing the crusie control the whole way. i finally ran out of gas at 420.1 miles. by the time i filled up at the next gas station, i was on fumes. it took all 16.1 gallons of gas to fill up. myb if i do 65mph i can get it over 30mpg and myb squeeze out another 50 miles or so.
