Vehicle Greases Explained

Grease is used to lubricate vehicle components where oil cannot be retained. It is commonly applied to bearings, joints, linkages, and chassis components that require long-lasting protection.

Unlike engine oil, grease is designed to stay in place and provide lubrication over extended periods.

What grease is

Grease is made from base oil combined with a thickener and additives. The thickener gives grease its semi-solid structure, allowing it to remain where it is applied.

The base oil within the grease provides lubrication, while additives help control wear, corrosion, and oxidation.

Where grease is used

In vehicles, grease is commonly used in wheel bearings, suspension joints, steering components, and universal joints.

These areas are exposed to load, movement, and contamination, making grease more suitable than liquid oil.

How grease works

When a greased component moves, small amounts of oil are released from the grease structure to lubricate the surfaces.

As movement slows or stops, the grease remains in place, ready to provide continued lubrication when needed.

Different grease types

Vehicle greases vary depending on thickener type, base oil, and additives. Some are designed for high load, others for water resistance or temperature stability.

The formulation determines where the grease can be used safely and effectively.

What grease is not

Grease is not a replacement for engine oil or transmission fluid. It is not suitable for components designed for circulating lubrication.

Its purpose is to provide long-term lubrication where oil would leak away or fail to stay in place.
