Indeed, still getting 10% less mpg... It's ridiculous... what bothers me even more is that the car computer is showing higher MPG... in other words, on the computer, E70 is doing 10% less than the E53, and in real world (calculated by hand), I am losing another 10%... so that's 20% less....

Just crazy! I lost 25 liter in 107km... that's 10MPG while the computer is showing 11.5 MPG at a speed of 22KM/H at which the E53 used to make 12.7MPG... so yes, that's 20% less miles... what the .... any idea?
