How many liters of engine oil should be added to a BMW X5?

BMW X5 requires 6.5 liters of engine oil. Here is some relevant knowledge about adding engine oil: Standard for adding engine oil: Generally, it is best to add engine oil to the middle level between the upper and lower limits on the dipstick. Try not to go below the middle level because high-speed driving can cause the engine oil to become thinner due to the high temperature of the engine. If the oil level is too low, it will reduce the lubrication effect. It is acceptable to have a little more than the middle level, but never exceed the upper limit on the dipstick. Effects of overfilling engine oil: Excessive engine oil will increase the internal rotational resistance of the engine, leading to higher fuel consumption. Additionally, too much oil will raise the internal oil pressure of the engine, putting extra pressure on the oil seals and piston rings inside the engine. This can cause premature damage to the crankshaft and valve seals, resulting in engine oil leaks. Moreover, the high pressure and excessive oil can prevent the piston rings from sealing the upward-moving lubricating oil in the cylinder, causing oil to enter the combustion chamber and leading to oil burning.
