PETRONAS Akcela UNITEK PLUS 10W-40 is a synthetic-based engine oil developed in collaboration with CASE/CASE IH and FPT for Final/Stage V engines fitted with the HI-eSCR2 system, common-rail injection, particulate filter and variable-geometry turbine. Its formulation, compliant with the latest stringent API CK-4 requirements, offers high oxidation stability to ensure optimised performance over extended drain intervals of up to 1,000 hours. It is fully backward compatible with the previous ACEA E9-16 and E7-16 classifications, so one oil can serve both current and earlier engine generations in a mixed fleet. Typical data: 14.8 mm²/s at 100 °C, viscosity index 151, pour point below -35 °C and a TBN above 10 mg KOH/g. PETRONAS Akcela UNITEK PLUS 10W-40 meets ACEA E11 and E7 and API CK-4 and CJ-4, holds the CNH MAT 3571 approval and delivers the CNH MAT 3521 performance level. Always consult the owner's manual for the recommended viscosity grade and specification. Available in 20 L packs.
