Technical Conclusion:

This technical conclusion addresses the non-conformance of the 5W-30 oil with specified parameters: foamability, HTHS viscosity, and CCS viscosityat -30°C.Foamability: The tested 5W-30 oil demonstrated excessive foam formation with values of 80/0-40/0-80/0, 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.

CCS Viscosity at -30°C: The Cold Cranking Simulator (CCS) viscosity of the 5W-30 oil was measured at 8414, which exceeds the specified maximum limit of 6600 for SAE 5W-30. This indicates inadequate low-temperature fluidity, potentially causing difficulties during cold starts engine wear in cold weather conditions.

Conclusion:

Based on the above findings, the 5W-30 oil does not meet the requirements to be classified a SAE 5W-30 due to nonconformance with foamability, 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.
