Understanding Grease Colors

Grease colors, such as red, black, blue, or green, may catch your eye, but do they actually hold any significance in terms of the grease’s characteristics?

Gray or black greases often contain molybdenum disulfide (moly) or graphite for severe operating conditions, but the vibrant colors like red or blue do not necessarily indicate temperature specifications.

Color Coding Of Grease

Manufacturers do not adhere to an industry standard for assigning colors to greases. This lack of standardization means that colors are primarily used for marketing purposes to differentiate between various grease types within a product line.

Common Grease Colors

Grease Color Common Application
Red Multipurpose synthetic greases
Blue Multipurpose greases made from conventional oil base stocks
Grey Contains moly for off-road equipment specifications
White Used in food-grade applications

It’s important to note that while the color of grease may offer a general indication of its intended use, it does not definitively specify its properties or performance capabilities.

Grease Quality and Color

The color of grease can sometimes provide insights into its overall quality, but it’s crucial to remember that color alone does not determine the effectiveness or superiority of a grease product.

Contaminated Grease

If grease appears milky, it could indicate water contamination. Mixing different greases in service may lead to a change in color, highlighting potential issues with compatibility.


While the color of grease may catch your attention, remember that it is not a definitive indicator of its properties or quality. Manufacturers use colors for branding and product differentiation, rather than as a standardized guide to the grease’s characteristics.

Next time you see red, blue, or green grease, know that the color is more about marketing than a specific performance attribute. Always refer to the manufacturer’s specifications and recommendations for the best results when selecting grease for your equipment.
