Mobil 1™ Synthetic Grease

High performance automotive grease

Mobil 1™ Synthetic Grease

Excellent protection against rust and corrosion

Mobil 1™ Synthetic Grease is an NLGI No 2 high-performance automotive grease which combines a synthetic base fluid with a lithium complex soap thickener. The thickener system provides a high dropping point, while additives impart optimum extreme-pressure properties and excellent resistance to water wash, and outstanding protection against rust and corrosion. Mobil 1 Synthetic Grease has excellent structural stability. The synthetic base oil used in Mobil 1 Synthetic Grease gives it excellent performance properties at both high and low temperatures. High structural shear stability coupled with a high performance base oil make Mobil 1 Synthetic an outstanding automotive grease.
