Product Description

UNI B 10W/30 CK-4/E9 engine oil is the latest Full synthetic CK-4/E9 rated multi-grade high performance detergent-type diesel and petrol engine oil developed to meet the OEM new engines and the down speeding negative operating conditions experienced with the latest high performance diesel engines.

Down speeding and new technologies in modern Diesel engines has led to lower emissions but also higher torque in the key elements of the engine, which in turn lead to higher combustion pressures and temperatures. This leads then to higher oxidation and oil thickening. Hence the necessity for a new Uni-B CK-4 oil technology.

The oil is specifically engineered to provide significantly better wear protection, easy cranking in cold weather, lower emissions, and very high temperature stability. This formulation conforms to the requirements of PC-11 engine technology for use in diesel engines where API CK-4 or CJ-4 and below is recommended.

Formulated with high purity, hydrotreated Full synthetic base oils, it provides a superior level of protection against wear, sludge formation, acid corrosion to maintain engine cleanliness and extend oil life and the life of all moving parts subject to wear, even under severe operating conditions. Highest TBN ensures protection in LSD + ULSD fuels + extended drain intervals.


  • Significantly higher performing than CJ-4 rates oils.
  • Up to 63% better antioxidant and oil thickening performance than CJ-4.
  • Massive improvement in aeration control to aid use as Hydraulic fluid. Ad pack developed in conjunction with Caterpillar.
  • Excels in anti-corrosion and anti-oxidation tests to markedly extend engine cleanliness and oil life.
  • Extended drain intervals of up to 96,000 Kilometes with appropriate condition monitoring.
  • Formulated to maintain viscosity under the high shear, high pressure and high combustion temperatures produced in modern trucks torque increases.
  • Outstanding cylinder, bearing and ring wear and oil consumption control as shown in Mack T-12 tests.
  • Minimal cross feed & injector screw weight loss.
  • Excellent bore polishing results.’
  • Maximum TBN retention even after long mileage.
  • Unsurpassed piston deposit performance in Cat 1N tests.
  • Almost doubles the lead and copper corrosion performance results of CJ-4 oil.
