The formulated oil has a composition including major a amount of lubricating a oil base stock and minor a 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 en - gine tests selected from TU3M, Sequence IIIG, Sequence IVA and OM646LA. Also provided are lubricating engine oil composition having improved wear protection.
