Data verified by Nick Marchenko, PhD
Maintaining the engine oil in your BMW 750 is crucial for optimal performance and longevity. This luxury sedan, produced between 1999 and 2012, features five distinct engine options, each requiring specific oil specifications. The M73B54 engines, available in 1999 and 2001, have an oil capacity of 8.5 quarts and utilize 0W-30 viscosity oil. The N62B48 engine, found in models from 2006 to 2008, also requires 8.5 quarts of 0W-30 oil but boasts a higher output of 362 hp.
For those with the N63B44A engine, produced from 2009 to 2012, the oil capacity increases to 9 quarts, maintaining the same 0W-30 viscosity. Additionally, coolant capacities vary across these engines, with the M73B54 requiring between 12.7 and 13.7 quarts, while the N62B48 and N63B44A engines need 15.3 and 15 quarts, respectively. Regular oil changes are essential to keep your BMW 750 running smoothly and efficiently.

How many quarts of oil does the BMW 750 take?
The oil capacity varies by engine: the M73B54 and N62B48 engines require 8.5 quarts, while the N63B44A engine requires 9 quarts.
How often should I change oil in a BMW 750?
It's generally recommended to change the oil in your BMW 750 every 7,500 to 10,000 miles, depending on driving conditions and oil type.
What is the coolant capacity of the BMW 750?
The coolant capacity varies by engine: the M73B54 requires between 12.7 and 13.7 quarts, the N62B48 needs 15.3 quarts, and the N63B44A requires 15 quarts.
Does the BMW 750 need synthetic oil?
Yes, the BMW 750 is designed to run on synthetic oil, which provides better protection and performance compared to conventional oil.
What happens if I use the wrong oil viscosity in my BMW 750?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating, negatively impacting performance.
What is an oil life monitor and how does it work?
An oil life monitor tracks engine conditions and driving habits to determine when an oil change is necessary, helping to optimize maintenance schedules.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oils, it's not recommended as it can reduce the effectiveness of the oil and compromise engine performance.
How do I know if my BMW 750 has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regular checks can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets. It may also result from engine overheating or using the wrong oil type.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is warm but not hot, as this allows for a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining old oil and replacing it with new oil, while a flush is a process that cleans the engine's oil system to remove sludge and contaminants.
