just changed the oil for the first time on my 2002S with 63K kilometers (37K Miles)..I wasn't sure when the previous owner had done the last change so I decided to make a clean start. I wasn't able to find Mobil 1 10-40 so I ended up using Mobil 1 5-50. The oil I drained looked clean, the oil filter cup was clean also. I was dreading cutting open the paper filter to see what was in there. I was pleasantly surprised to see that it was completely clean. I'm hoping this means I have no bearing issues at the moment. It took over 9 quarts of oil. Next project is changing tires (new Michelin PS2) and new rotors and pads.
