Technical Conclusion:
This technical conclusion addresses the non-conformance of the 0W-30 oil with specified parameters: foamability, HTHS viscosity, and CCS viscosity at -35°C.
Foamability:
The tested 0W-30 oil demonstrated excessive foam formation with values of 130/0-50/0-130/0, significantly surpassing the standard range of 10/0-50/0-10/0. Excessive foam can degrade lubrication efficiency, potentially leading to diminished engine performance and increased wear.
HTHS Viscosity:
The High Temperature High Shear (HTHS) viscosity of the 0W-30 oil measured 3.468, falling short of the required minimum of 3.5 as per Dexos 2 and ACEA C3 standards. Insufficient HTHS viscosity may compromise the oil’s ability to maintain adequate lubrication under high temperature and shear conditions, jeopardizing engine protection.
CCS Viscosity at -35°C:
The Cold Cranking Simulator (CCS) viscosity of the 0W-30 oil was measured at 10496, which exceeds the specified maximum limit of 6200 for SAE 0W-30. This indicates inadequate low-temperature fluidity, potentially causing difficulties during cold starts and increased engine wear in cold weather conditions
Conclusion:
Based on the above findings, the 0W-30 oil does not meet the requirements to be classified as Dexos 2, ACEA C3, or SAE 0W-30 due to non-conformance with foamability, HTHS viscosity, and CCS viscosity standards. Addressing these deficiencies is crucial to ensure the oil meets performance expectations and regulatory compliance.
This technical assessment underscores the importance of adhering to specified parameters to maintain optimal engine performance, efficiency, and longevity.
