The test identified a critical absence of magnesium in the REDEX 5W-30 formulation. Magnesium is often included in modern engine oils, especially those meeting the MB229.51-2022 specification, to help protect against LSPI (Low-Speed Pre-Ignition), a serious issue for turbocharged gasoline direct-injection engines. Impact on LSPI Protection: Without magnesium, the oil may not provide sufficient protection against LSPI, which is a known cause of engine knocking and damage in modern turbocharged or direct-injection engines. Compliance with Modern Specifications: Although the oil may meet older versions of the MB229.51 standard and other specifications like VW50400/50700, the lack of magnesium could prevent it from meeting the latest requirements of MB229.51-2022, particularly in preventing LSPI and related engine issues.
