ZDDP as most available oils. (Not for use with catalytic-equipped vehicles.)

10w40 and 20w50 viscosity, and contains superior anti-wear zinc and phosphorus
additive packages for exceptional levels of protection, especially important in the
high stress conditions of racing.
they have a brake in oil now. (and its MADE IN THE USA)

zinc and is formulated to offer superior protection.
This oil also adds high levels of wear protection and
ring sealing during break-in periods.
