F-150 Eight MPG

Come on! I have placed this question twice before with no reply. Surely someone can help me. I have a 2005 F-150 XLT 5.4 liter with a 3.73 rear end ratio and 9800 miles. I purchased it new in July 2005. It gets 18 mpg on the interstate, but only gets 8 mpg consistantly in town. I am really disappointed. Is this normal, or could I have a problem that can be fixed?

I do better than that in town with my V-10. Your highway mileage sounds great, but the city is terrible. I wish I could help, but the only advice I can offer is to sign up and ask at the Ford Truck Enthusiasts Forum. Lot's of knowledgable folks over there too.

maybe you have a lead foot in heavy traffic, you know flooring it up to a traffic light and then slamming on the brakes.

Are you getting any engine warning lights indicating a problem with the computer system. Does it idle properly or is the engine rough. without any problems you probably have a lead foot. How many miles since it was tuned up.

Ive answered this same question before, check the timeing, it can make all the differance in the world as far as gas mielage.
