Abstract: This disclosure is directed to a lubricant composition having improved compatibility with fluoropolymer seals. The lubricant composition includes a base oil and a sulfonate ester. The disclosure is also directed to an additive package for a lubricant composition that provides improved compatibility with fluoropolymer seals. The additive package includes the sulfonate ester. The disclosure is also directed to a method of improving compatibility of a lubricant composition with a fluoropolymer seal disposed in an internal combustion engine. The sulfonate ester improves the compatibility with fluoropolymer seals of the resultant lubricant composition.
