Technical Conclusion:
- Absence of Magnesium:
- The oil lacks magnesium-based additives, which are crucial in modern engine oils to prevent Low-Speed Pre-Ignition (LSPI), especially in turbocharged gasoline direct-injection engines. Magnesium is a common ingredient in oils that meet newer standards, like PSA B71 2312-2022.
- Impact: Without magnesium, this oil may not provide sufficient protection against LSPI, which could be harmful to newer turbocharged or direct-injection engines.
- Phosphorus Content Inconsistency:
- The oil’s phosphorus content is measured at 0.077%, exceeding the 0.065% limit specified by PSA B71 2312-2013.
- Impact: This discrepancy disqualifies the oil from fully meeting PSA B71 2312-2013 requirements, as elevated phosphorus levels could lead to excessive engine wear or deposits over time.
Final Verdict:
The Castrol Magnatec 0W-30 ACEA C2 oil fails to meet the PSA B71 2312-2013 specification due to the absence of magnesium and an inconsistency in phosphorus content. While it may meet older standards, it is not ideal for modern engines requiring the latest protection measures, such as LSPI control and precise phosphorus limits.
