What does ACEA mean for engine oil?

[McPresley]

ACEA in engine oil stands for the abbreviation of the European Automobile Manufacturers' Association. The specific introduction of engine oil is as follows: 1. Lubricity: Under various conditions, the ability of engine oil to reduce friction, slow down wear, and prevent metal sintering is called the lubricity of engine oil. The viscosity of engine oil is an important indicator for evaluating lubricity. 2. Low-temperature operability: The performance of engine oil to ensure easy starting and reliable fuel supply under low-temperature conditions is called the low-temperature operability of engine oil. 3. Functions: Alleviate friction and high temperature; reduce gas leakage and prevent external pollutants; buffer the pressure rise in the engine cylinder port.
