What Does the MAT Number Mean?

The MAT number is one way that CNH Industrial lubricants differ from the competition. MAT is a series of internal technical standards developed by CNH Industrial engineers to ensure that all OEM-spec lubricants exceed industry-standard API requirements and have tighter tolerances than industry-standard specs. MAT numbers certify that our lubricants are engineered to protect the advanced technology in your equipment and help extend component life. No other maintenance solution can make that claim.

Specifications:
