AMSOIL Synthetic High-Viscosity Grease (GVC) is a lithium-complex-thickened grease blended with premium ISO-320 synthetic base oils. This grease is fully compounded with additives providing EP protection, oxidation resistance and rust and corrosion protection. AMSOIL High-Viscosity Grease is shear stable, maintaining its viscosity and consistency in the presence of mechanical activity. It also stays in place by resisting water washout. During high-temperature operation, AMSOIL High-Viscosity Greases thickener system remains intact and the high-viscosity base oils resist thermal breakdown, providing a thick film for good boundary lubrication protection. AMSOIL GVC adheres to critical components in severe conditions to provide problem-free operation, resulting in increased uptime and reduced repair and maintenance costs.

AMSOIL Synthetic High-Viscosity Grease is excellent for use in heavy-duty industrial and off-road applications where equipment operates under adverse conditions, including exposure to environmental elements, slow, heavily-loaded applications and shock-loading conditions. AMSOIL High-Viscosity Grease is formulated to excel in wet applications requiring excellent water resistance and in high-temperature applications up to 177C (350F) in continuous service and 204C (400F) in intermittent service. The lithium-complex thickener system and high-viscosity base oil provide top performance in hostile environments and heavy-duty industrial or offroad applications where typical multi-purpose greases may not perform up to standards.

AMSOIL High-Viscosity 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 the new grease while the mechanism is in operation. Closely monitor the system for any inconsistencies. Any grease compatibility questions should be referred to your AMSOIL representative or AMSOIL Technical Services.

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 onehalf full of grease. Prevent over-greasing as this can result in excessive heat buildup. Supplement standard grease maintenance by periodically cleaning and packing housings with fresh grease on an established maintenance schedule.
