Lucas Oil Marine Grease

Lucas Oil Marine Grease: Built for the Water

When it comes to protecting the moving parts on your boat, trailer, and outboard motor, the grease you choose matters as much as the oil in your engine. Lucas Oil — the American-made lubricant brand founded in 1989 and trusted by mechanics, fleet managers, and performance enthusiasts worldwide — brings that same commitment to engineering excellence to its Marine Grease lineup.

What Makes Lucas Marine Grease Different

Lucas Marine Grease is not a one-trick product. It is a premium, heavy duty lithium complex NLGI GC-LB certified grease formulated with a unique additive system designed to provide maximum lubrication under the most severe marine operating conditions. At its core, Lucas Oil Marine Grease is a premium multi-purpose calcium sulfonate complex grease with inherently superior resistance to corrosion and water washout, excellent mechanical stability, and extreme pressure protection.

One of the most demanding tests for any marine grease is its extreme pressure (EP) rating. Its fortified formula provides excellent extreme pressure properties, effective water resistance, and shock loading protection as indicated by a typical weld point of 500 kg — well above the minimum industry standard of 200 kg. That kind of load-bearing performance is critical in trailer wheel bearings and outboard components that endure constant vibration and stress.

Corrosion and Water Resistance Where It Counts

Salt water is one of the most corrosive environments any lubricant can face. Lucas Marine Grease provides excellent fresh water and salt water corrosion protection. It has been designed to lubricate under the most severe operating conditions in marine applications, and because of its adhesive properties it effectively stays in place — even when exposed to spray, submersion, or repeated washing. Formulated with a calcium sulfonate additive system, this grease provides increased lubrication across the boat for rust and corrosion prevention, while the adhesive design helps keep the grease in place.

A Truly Universal Marine Grease

Lucas Marine Grease is a truly universal marine grease with applications in trailer wheel bearing, trailer chassis lubrication, and outboards. It also has crossover applications in automotive wheel bearing and chassis lubrication — making it a practical choice for boaters who tow their vessels and want a single, reliable grease for the entire rig. Lucas offers the grease in multiple formats, including standard 14 oz. cartridges that fit conventional grease guns, compact 3 oz. mini cartridges ideal for field use, and convenient 16 oz. tubs for bench-top application.

The Lucas Oil Difference

Lucas shines as a proud American brand that embodies a unique blend of family leadership, U.S.-based manufacturing, scientifically superior solutions, and a commitment to community impact. Lucas Marine Grease is a premium, extreme pressure, multi-purpose, heavy duty OBCS grease containing unique polymers, anti-wear agents and tackifiers with inherent rust and oxidation resistance to provide the highest performance properties. Whether you are greasing trailer hubs before a weekend launch or servicing outboard fittings at season's end, Lucas Marine Grease delivers the protection that serious boaters demand.
