I finally got around to changing the Royal Purple in my S with 5K on the oil. I drained it and put in a new WIX filter and filled her up with DT-40. The DT-40 seemed much thinner in viscosity than the Royal Purple....much lighter in color. No problems and I do not what to be one of those guys that thinks everything is better........but the car did sound smoother and quieter running the DT-40 on the way home. My magnetic filter housing did nothing at all....a waste of time. I will post some pics later
