The BMW 3 Series requires approximately 5.5 liters of engine oil. The specific amount can be checked via the electronic oil dipstick, and the recommended oil grade for the BMW 3 Series is 5W30. Information about engine oil is as follows: 1. Engine oil: (Engine-oil) is the lubricant used by the engine. 2. Composition: It consists of base oil and additives. The performance characteristics of engine oil include: 1. Lubricity: Under various conditions, the ability of engine oil to reduce friction, minimize wear, and prevent metal sintering is referred to as 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 that ensures the engine starts easily and reliably supplies oil under low-temperature conditions is called the low-temperature operability of engine oil. The low-temperature operability of engine oil includes facilitating cold starts and reducing start-up wear. 3. Viscosity-temperature characteristics: The property of lubricating oil to change viscosity with temperature fluctuations is called viscosity-temperature characteristics. Good viscosity-temperature characteristics mean that the oil's viscosity changes minimally with temperature. The effect of temperature on oil viscosity: as temperature increases, viscosity decreases; as temperature decreases, viscosity increases.
