How many liters of engine oil should be added to the N52 engine?

The BMW N52 engine requires 7L of engine oil. Here are some precautions when adding engine oil: 1. Generally, the oil should be filled between the upper and lower limits on the dipstick. (1) Overfilling the oil can affect the normal operation of the crankshaft and also increase the vehicle's fuel consumption. (2) Insufficient oil may not provide enough lubrication for circulation, leading to accelerated wear of internal engine components and potential engine damage. 2. After adding the oil, start the vehicle for a while, then turn it off and wait for 3 minutes before checking again to confirm if more oil needs to be added. This is because when changing the oil, the oil filter also needs to be replaced, and the new oil filter initially contains no oil. After starting the vehicle, oil will flow into the filter. Waiting for 3 minutes allows the oil to flow back into the oil pan, ensuring a more accurate measurement.
Regarding how much oil to add to the BMW N52 engine, I've driven cars with this engine for several years and found that it's generally around 6.5 liters, but this isn't absolute—it depends on specific circumstances like whether the oil filter is being replaced as well. If you're only adding oil during a change, I recommend buying a 5-liter jug of synthetic oil plus a 1.5-liter small bottle for more precise control. Don't overfill, as excessive oil pressure can damage engine components; underfilling leads to insufficient lubrication and increased wear. Just check the dipstick regularly to ensure the oil level is at the midpoint—it's simple and requires no tools. Before each service, I review the vehicle manual or look up model-year specifics online to confirm the exact amount and avoid mistakes, saving money and ensuring peace of mind. The N52 is an old but reliable engine—don’t ruin it with minor oversights. Remember, 5W-30 viscosity is suitable for most driving conditions.
