I am buying BMW 540i automatic petro version sedan. What kind of Petrol should I use for this car. Will also will it affect the average per km if I use a low regular petrol instead of high octane petrol??

The information I have shows these vehicles require the premium high octane fuel - so in this case you won't have the choice of using a lower octane fuel.

From the info I have the E39 4.4L or 4.0L V8s use a 15W40 semi-synthetic engine oil API/ACEA - SL/A2, A3.
