How much engine oil should be added to a BMW 5 Series 2.0t?

[LeBethany]

The 2.0t engine of the BMW 5 Series requires 5 liters of engine oil. Here is some introduction about car engine oil: 1. The function of BMW 5 Series engine oil is to lubricate and clean the engine. 2. It can be divided into three types: mineral oil, synthetic oil, and semi-synthetic oil. All engine oils are composed of base oil and additives. 3. Overall, full synthetic oil contains 100% non-conventional, high-performance fluids. Semi-synthetic oil contains a smaller percentage of such high-performance fluids and includes conventional mineral oil. Additional information: If too much engine oil is added to the BMW 5 Series, the amount of oil splashed into the cylinder wall when the crankshaft and connecting rod rotate increases, which means the amount of oil entering the combustion chamber greatly increases. This leads to more carbon deposits in the combustion chamber, increases the resistance of piston movement, and reduces engine power. As the amount of oil entering the combustion chamber increases, exhaust emissions deteriorate, affecting the lifespan of the three-way catalytic converter. In severe cases, it may even damage the three-way catalytic converter.
