For anyone with a strictly race set up I can get AMSOIL Dominator Racing Oil.

Provides superior performance and maximum protection in high-performance and racing applications. DOMINATOR is engineered from advanced synthetic technology to better withstand the elevated rpm, high temperatures and shock-loading common to racing applications. Will last for 5,000 KM or 1 year whichever comes first.

Available in: 5W-20, 10W-30, 15W-50, and SAE 60.

Thank you,

Ryan
