Just wanted to let 2.5L owners that this German oil is a great oil for this engine. Much better than the Castrol Edge 5w-40 which has been in my engine for the 2 previous oil changes. Very noticeable the difference. Engine runs super smooth and I believe once you try this oil, it will be your oil of choice. I know this is all I'll use from now on. (Due two more "free" Oil changes from dealer but I believe I'll either bring in my own oil or drain the dealer oil and use elsewhere.) More about oil can be read on this website: Bob is the Oil Guy. Cheers and safe, happy and properous New Year to everyone!
