Interchangeable and linked group II base oils
In accordance with API and ACEA protocols, Saudi Aramco has successfully completed test programs that demonstrated the interchangeability and linkage between Group II base oils from our global manufacturing sites.
The extensive testing programs covered API SN/GF-5, API CJ-4 and ACEA A3/B4 automotive engine oils together with demonstration in industrial and gear oils applications. Engine tests to meet ACEA E7 and E9 are currently underway with completion expected Q3 2018.
Automotive engine tests
Sequence IIIH engine test (API SN/GF-5)
Sequence IIIH engine test (API CJ-4)
European engine test (ACEA A3/B4)
The Group II base oils show satisfactory performance in various API and ACEA engine tests across a number of metrics including oxidation, anti-wear, piston cleanliness, and sludge formation resistance using suitable additive technologies.
