I think the X5 4.4 and 3.0 is an OK vehicle on fuel consumption but I have noticed in the last 2 years my consumption dropping a bit too. I use seafoam every 4-10 tank fulls to clean it out.
use it in your oil for 150 kms before an oil change too. does wonders

well u have seen the x5 your self and how clean it was/is im still a few k km from an oil change but will add it when it comes time to
