I think the engine runs smoother or with more ease with the new mobile 1. The old oil seemed to have good viscosity but it had a bit of metallic color to it. I am glad I changed it before 4K. I reset the oil schedule in the computer after the change. I was sorry to see a small oil filter on a car with a oil lubricated turbo. I suppose its sufficient. Alan
i have been meaning to bring that up, different brand of oil.
i think owners here should experiment with different brands of higher end oil, such as mobil, motul, royal purple, etc just to see the differences and how it may improve our cars.
if it was up to me i would start with a motul 8100 that is appropriate for our vehicles engine
