Keywords: API, engine oils, standards, motor test methods, bench test methods, service categories, service symbol, read-across, oil interchangeability, low speed pre-ignition, resource conserving.
Abstract
The publication describes major aspects of the currently active American Petroleum Institute (API) engine oil performance categories that have been defined as «S» category: SN Plus, SN, SM, SL, SH and «C» category: FA-4, CK-4, CJ-4, CI-4, CH-4. The basic descriptions of every category were involved. It was underlined this specification is based on engine test results that generally have been correlated with results obtained on reference oils in actual service engines operating with gasoline or diesel fuel. All motor and bench test methods specified for above mentioned categories were reviewed. The Base Oil Interchangeability Guidelines – BOI, API Guidelines for SAE Viscosity-Grade Engine Testing – VGRA and Read-Across rule, Resource Conserving oils, Low Speed Pre Ignition — LSPI were explained. The fundamentals of FA-4 and CK-4 service categories have discussed.
