What's up with my BMW X3's fuel economy?
My 2004 BMW X3 has a serious problem of high fuel consumption; it uses one litre to drive a four-kilometre distance; what could be the cause?Sinani Simba (Dar Es Salaam)
That is indeed very poor fuel consumption. Lots of things could cause that, though one known issue in the early 2.5-litre petrol X3 is a cracked intake manifold. If that is your problem, then it will require replacement.
Best bet is to have the car looked at by a good mechanic.Shane O' Donoghue - Complete Car Advisor
