What Causes a Car to Leak Engine Oil?

[Aria]

Small car engine oil leakage is caused by the failure of rubber seals on the engine. The following is a detailed explanation about engine oil: 1. Definition: Engine oil, also known as engine lubricant (English name: Engine oil), has a density of approximately 0.91×103 (kg/m3). It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of two main components - base oil and additives. Base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, providing certain new characteristics. Additives are an essential part of lubricants.
