This is the second oil change my 2021 C63S has received and the first full interval using Mobil 1 FS 0w40. This car is a daily driver but I don't have any sort of daily commute.. I do like winding it out to hear that V8 pop and bang! The car has the hand-built, wet sump M177 bi-turbo 4.0L V8.
Actually a bit surprised that it was able to shear down M1 0w40 so far, and almost 10 quarts worth of it, but it doesn't seem to have caused an issue.
