Boat Trailer and Universal Synthetic Water Resistant Grease

Upgraded from the industry standard of Lithium to Calcium – handles even more pressure. Other greases wash off as if the water was detergent. AMSOIL’s boat trailer grease stays put!

Superior Lubrication and Protection in Automotive and Industrial Applications

Synthetic Water Resistant GreaseAMSOIL Synthetic Water-Resistant Grease is an extreme-pressure grease formulated specially for wet-duty performance. Composed of premium-quality synthetic base oils and calcium-sulfonate complex thickeners, Water-Resistant Grease provides exceptional film strength, shear resistance, adhesion properties and mechanical stability. Its water-washout and sprayoff resistance are outstanding for applications frequently exposed to water, mud, snow or ice, including ATVs, UTVs, snowmobiles and boat trailers.

Omaha note: This is our best selling grease in the Omaha store by the single tube. It is basically the multi-purpose with added water resistant protection. It makes the different between a boat trailer making it back home or stuck on the side of the road. I’ve had customers tell of the day and night difference it makes on a sleds suspension. It’s my personal choice for all hand packing of wheel bearings. The general use grease that stays put!

Water-Washout and Sprayoff Protection

The superior wet-duty performance of AMSOIL Synthetic Water-Resistant Grease is formulated with extra durable cohesive and adhesive chemistry. It holds together when exposed to water and clings tenaciously to metal surfaces when wet, protecting components during prolonged exposure to standing or pressurized water.

Corrosion Protection

Frequent or prolonged water contact can increase corrosion, resulting in damage to metal surfaces and compromised components. Water-Resistant Grease seals metal surfaces and chemically fights corrosion, making it ideal for applications with extensive exposure to water, mud, snow or ice.

Load-Carrying and Extreme-Pressure Performance trailer Grease

AMSOIL Synthetic Water-Resistant Grease protects components from metal-to-metal contact even under heavy loads. Its extreme-pressure additives protect against sustained or sudden extreme loads for dependable protection against wear.

Application Recommendation

AMSOIL Synthetic Water-Resistant Grease meets the highest performance standards set by the National Lubrication Grease Institute (NLGI) for wheel bearing applications (GC) and chassis applications (LB). It may be used in automotive wheel bearings, chassis or other applications for which an NLGI #2 GC or LB grease is recommended.

APPLICATION MAINTENANCE

Maintaining a clean work environment is important when equipment greasing is performed. Wipe grease fittings clean prior to injecting grease to prevent contaminant ingestion. Maintain bearing housings one-third to one-half full of grease. Do not over-grease, as excessive heat buildup can result. Supplement standard grease maintenance by cleaning and packing housings with fresh grease on an established maintenance schedule.

AMSOIL PRODUCT AVAILABILITY

AMSOIL Synthetic Water-Resistant Grease is available in 3-oz. cartridges, 14-oz. cartridges, 35-lb. lugs and 120-lb. kegs.

COMPATIBILITY

AMSOIL Synthetic Water-Resistant Grease is compatible with many other types of greases. However, it is recommended that, when changing greases, the equipment be cleaned of the old grease when possible or flushed with a liberal amount of Water-Resistant Grease while the mechanism is in operation. Closely monitor the system for any inconsistencies. Grease compatibility questions should be referred to your AMSOIL representative or AMSOIL INC.

Water Resistant Grease Customer Feedback!

Best grease around

By  MATT,  a  Verified Buyer  from  Maple Valley WA  on  July 07, 2025
This grease is great for everything! I use it on my outboard motors, wheel hubs/ bearings, and vehicle suspension parts. I live where I take my boat into salt water and since I have used this grease I have seen a difference in how it does not breakdown like other products after heavy temperature swings. I highly recommend it to anyone.
Only grease that doesn’t wash off.

A great water resistant grease!
By  ROGER,  a  Verified Buyer  on  February 26, 2025
I use this grease on my snowmobiles during the winter. It stands up to the severe temperature changes, and is great at resisting water contamination. Works great!
Works Well – Has Not Failed Us Yet
By  RUSSELL,  a  Verified Buyer  from  Tomkins Cove NY  on  November 21, 2024
I use this exclusively in bearings on boat trailers. I have owned boats and boat trailers since 1988. I have had a problem or 2 with boat Trailer bearings overheating and failure. Since I have started using this grease, I have not yet had a boat trailer bearing get hot or fail. Thank you for the product.
