2006 Ford F150 4WD with the 5.4L
On the way to work I noticed that the truck was "burning" a lot of gas. As I drove, (at a normal speed - 60 mph) I noticed that the Miles to Empty display dropped 4 miles within a distance that I know to be roughly 1 mile
I thought that there might have been something wrong with the engine or the fuel system; however,
- the truck has not produced any error lights (yet)
- I'm still getting the same average mpg as always (~16 mpg)
I then thought that I must have a leak, so I checked under the truck at a gas station. I checked for leaks dripping to the ground both while the truck was running as well as when it was not. I did not see any signs of gas on the ground
If anyone has seen a problem like this before and knows where I should start looking, or you can shed some light on the situation it will be much appreciated.
