Abstract

This disclosure is directed to an additive package for a lubricant composition that provides improved fluoropolymer compatibility. The additive package comprises a halide seal compatibility additive and a second seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil, a halide seal compatibility additive, and a second seal compatibility additive. The halide seal compatibility and the second seal compatibility additive improves the fluoropolymer seal compatibility of the resultant lubricant composition.
