摘要： The present disclosure provides a lithium complex grease with high-temperature resistivity and a method of using the same. The lithium complex grease includes: a lithium complex thickener, a friction modifier, a polymer or copolymer, and at least one synthetic base oil with alkylated naphthalene. The lithium complex grease can be substantially free of polytetrafluoroethylene.
