However, that doesn’t mean older engines can’t use the newest oil because most of the modern engine oil in today’s market are made to be backward compatible. Backward compatibility refers to the ability of an engine oil to be safely used in older or previous-generation engines without causing any negative effects. It ensures that newer oil specifications can still cater to older engine designs and requirements. For example, if the latest oil specification is API SN, it can likely be used in engines that require API SM, API SL, or even older specifications. But please be aware that a new car’s engine will not be compatible with the old engine oil so if your car is new then is best for you to consult a professional or you can WhatsApp us and we will answer all your questions.
