TotalEnergies launches its state-of-the-art Rubia Optima range of truck oils. In terms of technical and quality parameters, it is a completely new level on the market, confirmed by the latest specifications: API: CK-4, ACEA: E8 and E11, as well as a number of the latest approvals of MERCEDES-BENZ, VOLVO, RENAULT TRUCKS, CUMMINS, SCANIA, MAN.
The new API specifications: CK-4, ACEA: E8 and E11 significantly tighten the quality requirements for engine oils.
API: CK-4 is the latest standard that significantly tightens the quality requirements in relation to its predecessor CJ-4. Improved 100% oxidation resistance, shear loss and oil aeration. Increased requirements for: protection against catalyst "poisoning", DPF blocking, engine wear, deposits on pistons and oil viscosity increase associated with increased soot content - better dispersion.
ACEA: E8 and E11 are the tightened quality specifications released in 2022, to ACEA: E6 and E9 respectively. The new specifications significantly increase the requirements for oil oxidation in accordance with API CK-4 requirements, but also increase the requirements for anti-wear properties of liners and rings (new engine test - MACK T12). In addition, the requirements for piston cleanliness, ring sticking and sludge in engines when using fuel with an increased amount of biocomponents have been tightened, which are required in Europe (new engine test - MERCEDES-BENZ). Added test for oil resistance to aeration (new engine test - CATTERPILAR).
