The National Lubricating Grease Institute (NGLI) is an international trade association serving the grease and gear lubricant industry. NLGI has a grading system that assists customers in determining the viscosity or flow of any given grease. Many vehicle owner’s manuals specifically recommend greases that carry the NLGI Certification Mark on the label. Super Lube greases carry this mark, ensuring only the highest quality products for your vehicles.
NLGI grades are broken down by consistency:
- 000-0: Fluid; often used in specialized applications like centralized lubrication systems
- 1: Soft; used for bearings and some electric motors
- 2: Medium; the most common grade for various industrial and automotive applications
- 3: Medium-hard; used where higher stability is needed
- 4-6: Very hard; used in specialized applications requiring maximum stability
Super Lube grease NLGI grades can be found on their packaging and Technical Data Sheets.
