United Super Premium Fleet SAE 15W-40

United Super Premium Fleet SAE 15W-40 is an API CK-4/SN premium heavy-duty diesel engine oil formulated to provide improved wear protection and control of high temperature oxidation and soot control in both new and older model engines for on- and off-highway applications. This heavy duty diesel engine oil also provides better deposit control, reduced oil consumption, improved low temperature pumpability and controls soot-related viscosity changes.

Features:

• Exceptional shear stability and stay-in-grade viscosity beyond the API CK-4 performance category in support of extended drain intervals
• High Total Base Number (TBN) technology through a balanced formulation of detergents, dispersants and other additives to ensure maximum engine protection
• Unique soot-dispersing technology to diffuse soot to reduce oil thickening
• Excellent anti-wear, oxidation stability and corrosion protection for cleanliness and long engine life
• Enhanced aeration control protects against air, foam and bubbles to help maintain the integrity of the oil for proper film protection
• Excellent oil consumption control which will lower oil costs as a result of less make-up oil during operation
• Provides high film strength, excellent low temperature properties and retains viscosity during use
