I have a 2004 with the 4.6, 4-wheel drive and about 65000 miles. I get 20 MPG highway and normally see 10 MPG strictly city, not driving conservatively.

In the winter with the temps below freezing the MPG will drop about 2-3 MPG. We have 10 % ethanol gas which is 'modified' in the winter which probably accounts for some of the MPG drop.

I too have wondered about the poor city MPG...

2002 limited v8 4.6l

hwy=23-25mpg
around town=17-18mpg
My K&N intake came today so those numbers should change slightly so should be even better!

That could do it, a commute is how far the truck is driven before turning it off.

When the truck warms up to 195F it can achieve something called 'Closed Loop' where the ECU looks at the O2 sensors and adjust the air/fuel ratio for the maximum fuel economy. Before closed looks it essentially dumps far more fuel to keep it running till it achieves the operating temp 195F.

However 6mpg seems a tad low, check for vacuum leaks? have you change the spark plugs recently? Cleaned the MAF?

If you have the trip computer reset it and take it for a 25mile city drive, stay off the gas, keep the RPM's about 2,000 and see what you get.

Yes spark plug new, fuel filter new,air filter new. I will clean the MAF sensor and the Thruttle body next week. yes and check for leak. I am going to the city soon to instal 2 din dvd player and then I will reset the trip computer when I come to the city. And thanks for good respond. And I am going to take my friends V6 for ride in my town monday and try to drive short distance like I do in my car and see what I get. I will post the result...

In the right direction

ok back from the sea and chance the air fillter it was probably not new like the pre owner said. Chance to True Flow air fillter and unplug the battery for ten minutes..Have driven it 15 millage as well as I can here in town and computer shows 12,5 mpg so I am very glad, much better then my 6-7 mpg. Do someone here have any experience with True Flow air filter? It is oil-bath filter http://www.car-stuff.com/trueflowairfilter.htm ???Tomorow I will clean the MAF sensor snd add Bell-add http://www.belladd.dk/eng/home.asp?Poor performance / fuel economy=&ContentID=153 to the tuel. Hopfully it will do somthing extra...
