I have an 06 Crewcab Lariat 4x4 with factory 20" wheels. I have done absolutely NO modifications and the truck is stock with the triton v8. I have a 30 gallon tank and I average 10mpg if i'm lucky. Also, my low fuel indicator automatically comes on at exactly a 1/4 tank. I have taken it to the dealership 4 times and they keep telling me nothing is wrong and that their "COMPUTER" says i'm getting 15-18mpg.
My average is 260-270 miles out of 25-26 gallons. The needle is on "E" and the trip computer tells me I have 0 miles to empty, but yet I always have 4-6 gallons left when I fill up. WTF?!?!?!?!?!

Oh yeah...I bought it BRAND NEW in March 07 with only 300 miles on it due to having it transported. My current mileage is only 14,600. Obviously it's not my crazy driving skills!!

What are your driving conditions? Is it mainly highway or stop-n-go?

I drive approximately 18 miles roundtrip to and from work. 70% is on the highway and the other 30% is city.

Not sounding right, I get 16-18 mpg on my daily 100 mile commute to work even with the mod's I've done.

my dad has a 2006 super crew with a 5.4L and he can go about 350-400kms on one tank all highways with a few stops and his is bone stock

12.9 for my '06 Supercab 4x4 the last three tanks Ive put in it with about 75% highway driving.

I have the 5.4L Triton V8 with the 30 gallon tank. I'm lost for words on this problem and the dealership is pissing me off. I even thought it might be a tranny problem with the shift points not timed right causing it to stay in a low gear running the RPM's up at higher speeds. But that still doe not answer the question of my low fuel warning coming on at a 1/4 tank. Also sometimes when it has between 3/4 and a full tank...the needle will sometimes drop 1/8 to 1/4 of a tank at random times...then go back up.
