Technical Conclusion:

This technical conclusion addresses the non-conformance of the 15W-40 oil with specified parameters: foamability,

Foamability:

The tested 15W-40 oil demonstrated excessive foam formation with values of 50/0-100/0-50/0, significantly surpassing the

Standard range of 10/0-20/0-10/0.

Excessive foam can degrade lubrication efficiency, potentially leading to diminished engine performance and increased wear.

TBN VALUE /P Metal %: tested sample claims the ACEA E7 &VDS-3 compliances that is TBN > 9.0 & P metal content <0.08% but the oil demonstrated both out of specifications values as TBN 8.81 & P content 0.0899%.

Conclusion:

Based on the above findings, the 15W-40 oil does not meet the requirements to be classified a SAE 15W-40 due to nonconformance with foamability & TBN ,Metal content 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.
