markda said:I am not sure if it's the same over there on the US models, but my car has a BMW sticker under the bonnet which specifies exactly which type of Castrol oil the car requires, from memory it's Castrol TWS 10W60, also branded as Castrol RS and Castrol Edge as I understand. Question for the UK members, do you know where you can buy it?
I have looked high and low, ideally from a petrol station because I have a company fuel cardI have looked in most major motoring suppliers and nobody sells it? Used to be able to get hold of it no problem when I had my E46 M3. It seems it bit stilly buying it from BMW, but it's looking like I might have too...
Try the following for the Castrol
