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 get 17-17.5 on the highway. you got to take it easy, no fast starts, under 2500 RPM acceleration, etc and it will do it. i drive 20 miles per day to work 1 way, 90% at a constant 60 mph.

 

My 2000 5.4 4x4 gets 12 to 14 around town, 16 at best on highway,70 mph, downhill with a tailwind.

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.

 

I have a 97 F150 4.6 4x4 and 3.55 gears. My combined city and highway milage is about 16-17. Last tank got 17.2, not to sure what it gets on the highway.

 

12-13 in town, 16-17 on the freeway. 2003 F150 Supercab 2wd, 5.4, 3.55 gears, 100% stock, 30K miles, no leadfoot

 

Thanks alot guys. So about 13 is what everyone gets in town when takeing it easy.
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.

 

65-70 or so. Nobody here in California drives at 55 on the freeway, that's for sure. Even 65 is right lane only!

 

Ignore post.

 

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.
