How many liters of engine oil does a BMW 5 Series need?

BMW 5 Series requires 4 liters of engine oil. Below are the specific details about engine oil: The oil tank capacity of a BMW 5 Series is approximately 4 liters, so 4 liters of engine oil should be added. 1. Engine oil refers to the lubricant specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. 2. If too much engine oil is added to a BMW 5 Series, it increases the amount of oil splashed onto the cylinder walls by the crankshaft and connecting rods during rotation, increases the rotational resistance of the crankshaft, reduces the engine's output power, and increases fuel consumption. 3. It is advisable to keep the oil level slightly below the MAX mark on the oil dipstick.
I've been into car modifications for over a decade. The BMW 5 Series typically requires around 6 liters of engine oil, but the exact amount depends on the year and engine model. For example, older 520i models need approximately 5.7 liters, while newer 530d models might require up to 6.3 liters. When I change the oil myself, I always warm up the engine first to ensure the old oil drains completely. After replacing the oil filter, I use a funnel to add new oil slowly, starting with 5 liters. Then, I start the engine and let it run for a few minutes to circulate the oil. After turning off the engine, I check the dipstick and top up to the appropriate level. Be careful not to overfill, as excessive oil pressure can damage engine components. I recommend using full-synthetic oil like Castrol 0W-40 for better durability and extended engine life. It's essential to check the oil level regularly, ideally every 8,000 kilometers, to avoid breakdowns or issues on the road. Make sure you have all the necessary tools and take your time during the process.
Back when I just got my driver's license, I started researching BMW 5 Series maintenance. The engine oil capacity is clearly stated in the owner's manual - for instance, my friend's 2020 540i requires about 6.2 liters. Beginners should take it slow: wait for the engine to cool before draining old oil to avoid burns; add new oil in two stages - pour half first, start the car to warm up, then check the dipstick after two minutes for fine-tuning, never exceeding the MAX line. Underfilling may cause engine overheating and warning lights, while overfilling increases fuel consumption and costs. Longlife-17 FE certified oil is recommended for better BMW system compatibility. Make it a habit to check the dipstick quarterly for safety.
