What’s the Numbers About? • SAE 10W-30 • SAE= Society of Engineers • 10= Viscosity measured at 0 degrees • W= Winter grade oil • 30= viscosity measured at 212 degrees
API Rating • API=American Petroleum Institute • Rating progress from SA through SJ (s=spark ignition) • Diesel engines are rated with a “C” (compression) designation • These designations tell us what additive level is in the oil-Government regulated-2004= SJ or CF is mandatory. • Changing brand names of oil will not make a difference, As long as the API numbers are the same.
