I service 3 different fleets with different vehicles: Freightliner, Workhorse, Mack, Ford, International etc, and wanted a recommendation on the type / brand / quality of chassis grease I should use, thanks.

When it comes to selecting the appropriate chassis grease for your fleet, it's essential to consider several factors such as the application, operating conditions, and manufacturer recommendations. While I can't provide specific recommendations for every vehicle brand and model, I can offer you some general guidance.

Consult the vehicle manufacturer: Each vehicle manufacturer typically provides guidelines and recommendations for the type of grease suitable for their chassis components. Check the owner's manual or contact the manufacturer's customer service for specific recommendations.

NLGI Grade: The National Lubricating Grease Institute (NLGI) assigns grades to greases based on their consistency. Most chassis greases fall within the NLGI Grade 2 range, which provides good versatility and performance across a wide temperature range.

Lithium-based grease: Lithium-based greases are commonly used for chassis lubrication due to their excellent mechanical stability and water resistance. They also provide good protection against corrosion.

High-temperature resistance: Look for greases that offer high-temperature resistance if your vehicles operate in demanding conditions, such as heavy loads or extreme temperatures. These greases maintain their consistency and lubricating properties even under high heat.

EP additives: If your fleet includes vehicles with heavy-duty applications or exposed to extreme pressures, consider using a grease with extreme pressure (EP) additives. EP additives provide additional protection against metal-to-metal contact and reduce wear.

Regular maintenance and inspections: Regardless of the grease you choose, regular maintenance and inspections are crucial to ensuring proper lubrication. Check the grease condition periodically, and reapply or replace as needed.
