How many liters of engine oil should be added to a BMW 730?

BMW 730 requires 5 liters of engine oil. Generally, car engines have an oil dipstick, and the oil level should be between the high and low marks when adding. Engine oil is the lubricant used in engines, providing functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption and buffering. The BMW 730 is a large-sized vehicle with body dimensions of 5223mm in length, 1902mm in width, and 1498mm in height, and a wheelbase of 3210mm. In terms of power, the BMW 730 is equipped with a 2.0-liter turbocharged engine, which performs exceptionally well and offers quick acceleration.
I've been driving this 730 for five or six years, and it takes about 6.5 liters of oil every time I change it, as clearly stated in the BMW manual. Adding too little can burn out the engine bearings, causing increased engine noise and smoke; adding too much increases oil pressure, leading to leaks and even damaging the seals. I usually check the oil level with the dipstick when the engine is cold, making sure it stays between the minimum and maximum marks. Using the original 0W-30 synthetic oil is the most worry-free option—it provides excellent lubrication and improves fuel efficiency. I change the oil every 5,000 kilometers or six months, and when changing, remember to drain the old oil first. If the oil looks black, it's time to change it sooner. Keeping the engine well-maintained ensures smoother highway driving and extends its lifespan—don't skimp on this small expense. In winter, warm up the engine for two minutes before driving to protect it. Here's a tip: if you change the oil yourself, collect the used oil for recycling—it's both eco-friendly and safe.
