AI Technical Summary
Existing engine oil formulations struggle to simultaneously achieve engine wear protection, corrosion protection, and fuel efficiency, particularly with the increasing use of low viscosity engine oils and stringent fuel economy regulations.
An engine oil lubricant composition is developed, incorporating 0.1 wt% to 5.0 wt% of a polymeric ethylene oxide friction modifier and 0.1 wt% to 8.0 wt% of at least one viscosity modifier, which provides enhanced engine wear protection and anti-corrosion properties while maintaining fuel efficiency.
The composition effectively improves fuel economy while providing superior engine antiwear performance and anti-corrosion protection, addressing the challenges of low viscosity engine oils and stringent regulatory standards.
