There is more than one Mobil 1. There is the normal auto parts store version and there is also Mobile 1 4T which is targeted at high performance sport bikes and auto racing. The 4T is about double the price of the normal consumer Mobil 1. The Mobile 1 MX4T (as it was called then) is the oil I saw stacked up in cases in the pits of Texas Motor Speedway during a NASCAR race a few years ago. So I believe that could be the version of Mobile 1 used in big time racing. It appears to be available with API ratings of SM (small quantities of extreme pressure additives) and SH (larger quantities of extreme pressure additives).
