Abstract
Provided are lubricating engine oils including a lubricating oil base stock as a major component and an alkylated aromatic base stock as a minor component. One or more of engine wear and corrosion resistance are improved as compared to engine wear and corrosion resistance achieved using a lubricating oil containing a minor component other than the alkylated aromatic base stock, e.g., an ester having a D5293 viscosity of less than 10,000 cP at −35° C. In an engine lubricated with the lubricating oil, one or more of engine wear and corrosion resistance are improved as compared to engine wear and corrosion resistance achieved using a lubricating oil containing a minor component other than the alkylated aromatic base stock, e.g., an ester having a D5293 viscosity of less than 10,000 cP at −35° C. This improvement in engine wear and corrosion control means that engine oils can be formulated with very high saturate content base stocks such as PAOs or GTL stock while providing improved engine durability.
