Need Help Screw 4.6 or 5.4

I would like to say thanks to FX4Matt for referring me to this website. I'm looking forward to chip in and help this site grow.
I currently drive an 06 Ranger FX4 Level II. It gets a great 14.5 MPG on mixed driving. My lease is up next spring and I'm looking to get a F-150 since i'm done school now and can afford a little higher payment. I got my eyes set on the supercrew FX2. I know its not a 4X4 but i think I don't really need it as long as I get limited slip and traction control. Now my question is should I get the 4.6L or 5.4? All i tow is a 650lb quad and usually in the back of the bed. Whats the real world MPG ratings for a 5.4 vs 4.6L? As long as I can milk out about 16.5, I will be happy.. I look forward to the responses. Sc

My parents have 05 and 06 5.4 Supercrew's. I think 16.5 mixed driving with a 5.4 is a little high. The 4.6 might have better mileage but a supercrew is a big truck and a 4.6 has to work harder to move it around. I'd go with the 5.4

Hey

Welcome to FordTough.ca!

I've got '05 5.4 Supercrew and I do alot of highway driving..
I averaged 18MPG.. that is about 400-450highway.. 100 or so intown..

I just put some 33's on it and a leveling kit and it being winter have had it idling in the drive way warming up couple days.. so it isn't looking as good.. gunna see how this tanks works out though..

Go 5.4L I know some people who went 4.6L and regret it because fuel economy is about the same but it just isn't enough oomph for that big of a truck.

I have a 01 Supercrew 5.4L and I love it. It's not that hard on gas either.
