How many liters of engine oil does the BMW 730 require?
3 Answers
BMW 730 requires 5 liters of engine oil for an oil change. Below are the relevant details: 1. When checking the engine oil level, ensure the dipstick is free from contaminants. After completing the task, clean both the dipstick and its opening before reinserting. 2. It's essential to develop a habit of regularly replacing the air filter to ensure clean air intake. Neglecting air filter replacement can lead to significant losses due to minor oversights. 3. Be sure to prevent coolant from entering the cylinder, as water mixing with engine oil can form deposits. 4. Keep the oil cap clean at all times. 5. During oil changes, ensure the funnel and other tools are clean, and the contact area between the oil filter and the engine must also be wiped clean.
I have several years of experience driving a BMW 730. When changing the oil, the technician mentioned it requires about 6.5 liters, which is the standard amount for most models. I always double-check the manual to avoid mistakes. Checking the oil level myself is simple: start the engine for a few minutes, turn it off, pull out the dipstick, wipe it clean, and check again—the middle mark is ideal, and it’s best not to exceed the upper limit. BMW engines are delicate, so using 5W-30 or 5W-40 full synthetic oil is most suitable; avoid cheap options to prevent cylinder wear. I’ve also learned that overfilling the oil can cause smoke, leaks, and damage the catalytic converter, so I always have a professional handle oil changes. Regular changes every 10,000 kilometers extend engine life and save on repair costs—definitely worth it.
As an automotive enthusiast, it's important to know that the BMW 730 (F01 generation) typically comes with an N52 engine, with an oil capacity of around 6.5 liters. The key to selecting oil lies in the specifications, with 5W-30 being the best match for BMW's temperature requirements. When filling, use a small funnel and pour slowly to avoid foaming or oil pressure imbalance that could damage piston rings. If you're doing it yourself, prepare a new filter, add 4 liters first, then check the dipstick before adding more to ensure accuracy. Don't overlook details like oil temperature monitoring and pump pressure control, as keeping the oil circuit clean can improve engine responsiveness. Regular oil changes using reputable brands like Castrol are essential, and don't exceed 15,000 kilometers for stronger protection.
