The same high Zinc and Phosphorus formula as our original break-in oil, now in an 5W-30 viscosity for modern rebuilds and hydraulic lifter engines. Provides excellent ring sealing. Does not require additional ZDDP additives. Good for full power pulls on the dyno, one night of racing or up to 400 miles on the street.
