same approach as bowfer here, i know it may be wrong and lazy but i wait for the low warning light to come on too. mine come on for the first time yesterday at 6700 miles, which i still think is quite bad, our 535d and even porsche 997 dont use oil that fast or even the c220 cdi i had previously. it will make sense for people that have a few of these engines to buy a drum of this oil lol! another thing that bowfer has pointed out about the tyre pressures, i thought there was something wrong with the car, till i checked the pressures, which had only dropped a pound!! lets just call that a responsive chassis.....much more responsive than an f3 car which doesnt even react much to 1psi pressure drop/rise. i could go on, the steerings a bit wierd when the power assistance cant keep up, and the ride is a bit bouncy, (rebound is a joke), but i still love the car, it chews up miles and with quattro its effortless when covering ground quickly. fuel consumption is getting better despite the weather getting colder.i like it.
