What is the most common NLGI grease grade?

The most common NLGI grease grade is 2. NLGI, which stands for National Lubricating Grease Institute, classifies grease based on its consistency, with grades ranging from 000 (very fluid) to 6 (very stiff). Grease grade 2 is widely used in various applications because it strikes an ideal balance between viscosity and workability. It offers sufficient consistency for maintaining a lubricant film while still being easy to pump and apply, making it suitable for a diverse range of machinery, including bearings and general-purpose lubrication tasks.

This grade is favored in both industrial and automotive environments due to its versatility, which allows for effective lubrication across different temperatures and conditions. The prevalence of grade 2 grease in the market further reinforces its status as the most common choice for many lubrication needs.
