Gas Mileage?
I was wanting to know the gas mileage you guys get out of ya'll trucks.
I'm wanting to get a 2000ish F-150 at least extended cab 4wd with 5.4.
I've looked through old threads, and it looks like the 4.6 gets about 16 often.
What about the 5.4? Please tell me about 14 in town(if takeing it easy) and 16-18 on the highway at least.
Thanks for any help fellas.

I was averaging about 12 to 13 in town and 14 to 15 on the hwy before I got my Diablosport Predator programmer. Now I get 14 in town and 16-17 on the hwy. I also have kind of a lead foot. I get about 12mpg on the hwy towing about 7000lbs.

I have never calculated my mileage (never could fill the tank $$$$), but I would say I get 14 at best with mixed driving (mostly rural back roads/some hwy/some city).
Plus....33" MT's with stock gearing dont help...

Thanks for the help guys.
LxMan1, what's this Diablosport Predator about?
I can't say I've heard of it. Could you give me alittle info about it(what all it does, cost, how easy or hard to install), thanks in advance.

On the hwy, is it 17 mpg when going 55 or 70 or what(just to know what speed to try and keep it at).
Thanks again.

I was talking more about a hwy where the speed limit is 55, or interstate where limit is 70.
Either way, what do you guys do for best possible mileage other than keeping the foot away from the floor. Programers, k&n?
Free flowing exhaust? Anything bad with getting rid of the catalitic converters?(any sensors go crazy or somthing like that?)
Thanks for any help.

The programmer lets you run a more aggressive tune (timing and fuel) with all octane levels. I noticed the most mileage and power increase with the 93 octane tune. It has much better throttle response and a noticable increase in towing power. You can also firm up the shifts to eliminate the lag between gears (which will improve tranny life from less slippage between gears). You can also correct the speedo if you change tire sizes or gear ratios. Another handy feature is that it is a good code scanner that will log live data and you can monitor many functions as you drive. It will read and reset codes on most 96-newer vehicles with OBD-II, but monitors better on Ford products.
I usually drive about 10mph over the limit so usually 65 to 75mph on the hwy.
I wouldn't bother removing the cats, they seem to flow pretty good, I did install a single in dual out Flowmaster with dual tailpipes out the rear and a K&N replacement filter.
If this link works, here is more info on the Predator http://www.autoanything.com/performa...0A1924320.aspx
