BMW 730 requires 6.5 liters of engine oil. Generally, car engines have an oil dipstick. When adding oil, it should be filled between the maximum (upper limit) and minimum (lower limit) marks. Engine oil is the lubricant used by the engine, composed of base oil and additives. It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber, earning it the reputation as the 'blood' of the car. The BMW 730 has dimensions of 5273mm in length, 1902mm in width, and 1498mm in height, with a wheelbase of 3210mm. The engine in this car delivers a maximum horsepower of 265Ps, a maximum power of 195kW, and a maximum torque of 400Nm.

I remember the BMW 730 typically requires 5.5 to 6 liters of oil for an oil change, depending on the year and engine model. For example, the newer 3.0-liter turbocharged version needs about 5.7 liters. When I maintain my car, I regularly check the oil level every 8,000 kilometers and use synthetic oil to avoid deposit buildup. If not changed promptly, it can lead to engine wear, overheating, and major issues. Last time, a friend waited until the oil warning light came on and ended up spending thousands on repairs, so I recommend frequently checking the dipstick to ensure everything is normal. DIY oil changes might save some money, but beginners often measure incorrectly or leave leaks, so I prefer going to a professional shop for peace of mind. Nowadays, semi-synthetic oil is popular—it offers good value for money and can extend engine life by over 10,000 kilometers. Combined with the correct oil level, it makes maintenance much easier.

The oil capacity of the BMW 730 generally ranges around 5.5 liters, and may reach up to 6 liters depending on the variant. Based on my experience with luxury cars, it's essential to change the oil every 10,000 kilometers. Insufficient oil volume can reduce lubrication, leading to premature wear of engine components. Choosing the right oil type, such as SAE 5W-30, is optimal, and ensuring precise filling to avoid overflow is crucial. I prefer checking the dipstick when the engine is cold for timely adjustments. Saving on maintenance costs is straightforward—using high-quality oil can extend intervals, making fewer repairs and more driving the economical choice. Remember, regular upkeep prevents major overhauls. Investing a few hundred periodically ensures a decade of engine health, far more cost-effective than cutting corners.

Changing engine oil is crucial for safety. The BMW 730 generally requires 5.5 to 6 liters of oil, and neglecting it may cause engine seizure. I always pay attention to the oil level while driving, as maintaining it within the normal range protects the crankshaft and pistons. It is recommended to change the oil every 10,000 kilometers or every six months, using fully synthetic oil to prevent high-temperature failure. When checking the oil level, ensure the car is parked on level ground and the dipstick is firmly inserted for accurate readings. Don't underestimate the importance of oil level; missing checks or exceeding limits can lead to potential hazards. Maintaining good habits ensures safe driving, and regular maintenance is the right way to go.
