Remember the factory race teams use it. From Cart to F-1 to DTM to ralley racing. I use it in my 500E. I belive in it. My engine runs realy smooth. Even if you do burn a little oil,the viscosity of mobil compensate and still has a smooth running condition. The reason I made this point.with the other oils I would feel my engine rough through actually the gas pedal. It sounds nuts but I know cars and espcially mine.
