United Super Diesel Engine Oil SAE 10W-30

United Super Diesel Engine Oil SAE 10W-30 is an API CK-4 heavy-duty diesel engine oil formulated to provide improved wear protection and better 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 and reduced oil consumption.


  • Improved shear stability and stay-in-grade viscosity in support of extended drain intervals
  • Measurable improvement in fuel economy versus conventional SAE 15W-40 engine oil
  • High Total Base Number (TBN) technology through a balanced formulation of detergents, dispersants and other additives to ensure improved engine protection
  • Soot-dispersing and detergency technology to diffuse soot to reduce oil thickening
  • Formulated for anti-wear, oxidation stability and corrosion protection for cleanliness and long engine life
  • Improved aeration control protects against air, foam and bubbles to help maintain the integrity of the oil for proper film protection
  • Good oil consumption control lowers oil costs as a result of less make-up oil during operation
  • Provides high film strength and good low temperature properties
