Good day, dear friends I left my car for service at BMW yesterday for an oil service and vehicle check. I got the car, checked it off today and looked at what’s on it in the engine room. 1. The little note in the engine room was from Shell. Meaning that the oil was not original BMW but was filled in by Shell the oil or I get it wrong. 2. The actual topic, my vehicle was up to now always possible on 5w30 Now I see that there is simply 0w30 standing I can’t believe why this happens without agreement easy. Ask for helpful answers.
