It is often referred to as the "blood" of a car. Here is more information about automotive engine oil: 1. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives compensate for and improve any deficiencies in the base oil's performance, while also imparting new characteristics, making them a crucial part of lubricating oil. 2. The use of engine oil additives or other engine maintenance products is strictly prohibited, as they may damage the engine under certain circumstances and affect warranty coverage.
