Been flogged to a pulp, here...
run whatcha like.
I doubt that oil is going to make the M5 blink, but one might miss

From the Front Page of This Site, a good oil info capsule by
a knowledgeable poster, "withidl" : Lube 101.
Worth a read, even if it is slightly more than text message
in length, ;>)
