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
Agree. the more mods you do, the harder you drive:icon_twisted:,well it came out to
495kms on 97L's of fuel..
I used to get roughly 550.
but i really like the sound of the exhaust now so it's soo hard not to step on it.. lol
In that case..i think i might wait for an 09, but my gf keeps on telling me to buy an mkz..
