Mobil 1™ Synthetic Grease

Mobil grease , Canada

High performance automotive grease

Product Description

Mobil 1™ Synthetic Grease, the official automotive grease of NASCAR, is an advanced full synthetic grease formulated with a proprietary blend of high-performance synthetic base stocks and a lithium complex soap thickener. The thickener system provides a high dropping point, while additives impart excellent extreme-pressure properties and resistance to water wash, rust and corrosion. The proprietary blend of high-performance synthetic base stocks used in Mobil 1 Synthetic Grease gives reliable lubrication over wide temperature ranges -50 C (-58 F) to 246 C (475 F). Outstanding structural  stability coupled with high performance synthetic base stocks make Mobil 1 Synthetic Grease an outstanding all-purpose automotive grease.
