What type of engine oil is best for the BMW 730?
2 Answers
BMW 730 is better suited with SM-grade engine oil. Below are detailed information about the BMW 730:1. Model details: The BMW 730 is a high-end luxury car produced by the German automaker BMW. It belongs to the BMW 7 Series, manufactured exclusively in Germany, and replaced the previous generation BMW 6 in 1977. The BMW 730 is BMW's first large luxury four-door sedan, equipped with an inline six-cylinder engine.2. Precautions: The car must use engine oil of the appropriate quality grade. If temporary substitute oil is used, close monitoring is required, paying attention to whether the oil and oil filter are clogged.
When choosing engine oil for the BMW 730, it depends on the engine type and year, but I usually recommend using synthetic oil with BMW Longlife certification, such as 5W-30 or 0W-40, as these grades perform best. In my experience, BMW engines are very precise, and using unqualified oil can easily cause problems like unstable oil pressure or even shorten the engine's lifespan. I've seen many owners use regular mineral oil and end up spending a fortune on repairs. Look for oils labeled LL-01 or LL-04 to protect the turbocharging system, ensuring quicker starts and quieter operation. Don't forget to replace the oil filter regularly—about every 10,000 kilometers—and check the oil level to avoid leaks. For large temperature differences between winter and summer, opt for all-season oil to save money and hassle. Using the right oil can extend the engine's life by several years, making it a worthwhile investment.
