Abstract
A method for improving wear protection in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil having a HTHS viscosity of less than 2.6 cP at 150° C. The formulated oil has a composition including a major amount of a lubricating oil base stock and a minor amount of metal phosphate nanoplatelets. The metal phosphate nanoplatelets are dispersed in the lubricating oil base stock sufficient for the formulated oil to pass wear protection requirements of one or more engine tests selected from TU3M, Sequence IIIG, Sequence IVA and OM646LA. Also provided are lubricating engine oil composition having improved wear protection.
