It's an 04 5.4, 3.73 gears 4x4 with 120k. And like I said I usually get around 17-19 mpg, witch I guess is still good. I'm not sayin it's correct, I'm just asking if anyone else has seen the same thing.

I've only gotten 20MPG a couple of times since owning my 06 Screw new. Have 5.4L, 2wd, 3.73 LS axle, and 6.5ft bed. The best I can do is about 16-17MPG in the warmer months with a light right foot. I'm using Mobil 1 AFE 0W-20 motor oil, have Mobil 1 ATF in trans and Mobil 1 gear lube in rear axle.

My 2004 lariat 5.4 2wd with 48100 miles barely gives me 19 mpg on highway going 65 mph and around 9 to 10 on the city. I just have a k&n and a magnaflow also stock tires just got the 2.5" leveling

Update....Well the last day or two, it's come down to more normal numbers. Weird...
