No Product Data Sheet is available for Mobil 1R 0W-30 at this time. The oil is the *same* Mobil 1R used by the Penske NASCAR racing team, Team Corvette, etc. during the 2003 racing season. The oil is not API rated due to its much higher treat rates in anti-wear/phosphorous levels. The base stock used is a very sophisticated pao with performance characteristics well beyond that of PAO base stocks used in regular automotive oils.
It is in my Toyota Sequoia.......
