What API SP Demands of an Oil

API SP (2020) is the latest gasoline engine oil category, adding protection against low-speed pre-ignition (LSPI), timing-chain wear and turbocharger deposits over SN/SN PLUS, all within tight phosphorus limits. SP-targeted oils balance calcium/magnesium detergency, dispersancy and friction-modifier/antiwear chemistry to control deposits while preserving catalyst compatibility.

CheMost supplies the additive components a blender uses when formulating an oil to meet API SP. The category approval itself is held by the finished-oil marketer, not the additive supplier — the grades below are the chemistry that goes into such formulations.
