Overview
SF Grade is a range of multigrade and monograde engine oils based on mineral base oil, for gasoline cars and light, naturally aspirated diesel vehicles in normal service. Available grades: SF/CC 40, SF/CC 20W50, SF/CC 50. API lists SF as obsolete: it is not suitable for most gasoline automotive engines built after 1988.
Each grade is listed separately in the specification table with its viscosity at 100 °C, viscosity index, flash point, pour point, density and base number, so grades can be compared directly before ordering.
Application
Older gasoline cars
Vehicles whose handbook specifies API SF; API lists SF as obsolete for most engines built after 1988.
Application
Light naturally aspirated diesels
Light diesel vehicles without supercharging in usual working conditions, covered by the CC part of the SF/CC designation.
Feature
Published values by grade
SF/CC 40: KV100 15 cSt, VI 95, TBN 7, pour point -15 °C; SF/CC 20W50: KV100 19 cSt, VI 125, TBN 8.5, pour point -24 °C; SF/CC 50: KV100 19.5 cSt, VI 95, TBN 7, pour point -12 °C.
Feature
Choice of viscosity grades
3 grades in one product line, so a fleet can standardise on one API level across different climates or engine requirements.
