The typical chassis grease recommended for most construction equipment is lime base - water resistant. This type of grease offers excellent protection against moisture and water ingress, which is particularly important in the construction industry where equipment is frequently exposed to wet conditions. Lime-based greases contain additives that enhance their water resistance and provide a good balance between durability and lubrication under heavy loads, making them suitable for the diverse environments construction equipment operates in.

In contrast, other types of greases may not provide the same level of water resistance or may be designed for specific applications rather than the general use found in construction. For instance, calcium base greases may not hold up well in wet conditions, and soda base grease, while good for heat resistance, does not provide the necessary moisture protection for equipment exposed to the elements. Silicone-based greases can be useful in certain situations but may not offer the ideal performance needed for heavy machinery and equipment that frequently encounters water and contaminants.
