Hello everyone! Am from Dubai and am planning to purchase an used BMX X6 2008 model 35i with around 100k Km ... and like everyone else I have got a lot of questions. As per http://cararac.com/engine_oil/bmw/x6.html the recommended oil is: Synthetic 5w30 (6.5 litres) Could someone please advise: - Is this 5w30 the right one? What is the recommended brand? - how often shall I do the servicing ? - a workshop (third-party other than AGMC) for service (oil change) and what is the approx. cost? Also, is it better to purchase oil, filter (etc) separately? Thanks
