Fuel Correction factor, it is what you adjust when you fill up.
If memory serves the Gallons is on top (which you adjust) and the Fuel correction factor is at the bottom.
A FCF of 29% indicates that the engine is injecting 29% less fuel than it is reporting via OBDII.
Again if memory serves that would make the SGII mpg appear Lower than actual mileage.
Could just that his car has plugged injectors, I don't know, but I'm gambling on the Idea that those cars are alike . . . .
