No.1 Engine Oil™ #73344221 is bench tested, field tested and approved by CNH Industrial engineers to meet the stringent demands of today's Tier 4 engines. Low-SAPS (sulfated ash, phosphorus and sulfur) additive technology helps protect exhaust catalysts and diesel particulate filters (DPF) on the latest low emission vehicles.

As a safeguard against premature wear, our No.1 Engine Oil™ is engineered to the new, next-generation MAT 3571 specification. It has been extensively tested to provide maximum protection in oxidation and aeration control, shear stability and wear performance for heavy-duty, high-temperature operation of construction, agricultural and other off-road diesel-powered equipment.

• Best-in-class "Oxidation and Deposit Control" (37% higher resistance to oxidation vs. competition)
• Extended drain intervals for longer engine life and reduced maintenance costs and downtime
• Suitable for all heavy- and light-duty diesel engines in which API CK-4, CJ-4, CI-4 Plus, CI-4, CH-4 oils and 10W-40 are recommended
• Synthetic base oil stock provides improved cold starting and reduced fuel consumption

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.
