2016 BMW 750i Service Requirements & Maintenance Schedule

Key Takeaways

• The 2016 BMW 750i (G12 chassis) is powered by the N63R 4.4L twin-turbo V8 engine, with an oil capacity of 10.0 liters for rear-wheel-drive models and 10.5 liters for xDrive models .
• BMW's Condition Based Service (CBS) system uses sensors and driving data to calculate maintenance needs based on actual driving conditions rather than fixed intervals .
• Major scheduled service milestones include spark plug replacement at 60,000 miles, oxygen sensor replacement at 120,000 miles (repeat at 150,000), and another spark plug service at 120,000 miles .
• For the N63R V8 engine, BMW recommends replacing spark plugs every 30,000–40,000 miles—shorter than the CBS interval due to the high-performance nature of the engine .
• The recommended engine oil is BMW 0W-30 LL01FE for the N63R engine family .

Understanding BMW's Condition Based Service (CBS) System

The 2016 BMW 750i utilizes BMW's Condition Based Service (CBS) system, which actively monitors engine and vehicle components for wear to determine when maintenance is needed . Unlike traditional fixed-interval maintenance, CBS adapts based on driving style, mileage, trip length, and component wear.

The CBS system tracks oil life through mileage, fuel consumption, and information from an oil quality sensor located in the oil pan . Service status can be checked through the iDrive system; a green "OK" symbol indicates the system check is up-to-date, while a yellow triangle icon suggests listed components are due for servicing . The system monitors engine oil, brake pads (front and rear separately), brake fluid, spark plugs, and other components .

Important Note: Service information is stored in the vehicle's remote key fob, which your BMW service advisor can read to determine the appropriate service procedures .

Engine Specifications

The 2016 BMW 750i is equipped with the N63R 4.4L twin-turbo V8 engine (engine code N63B44B) .

Factory Maintenance Schedule

The following maintenance intervals represent key factory-recommended milestones for the 2016 BMW 750i. Exact intervals are determined by the vehicle's CBS system based on driving conditions .

Engine Oil and Filter Change

Motor oil is the single most important element in keeping your engine healthy. The 2016 750i uses the N63R 4.4L twin-turbo V8 engine with important oil capacity specifications .

Critical Oil Capacity Note: BMW issued a technical bulletin correcting the engine oil capacity for N63R vehicles. For rear-wheel-drive models, the correct capacity is 10.0 liters. For xDrive models, the correct capacity is 10.5 liters .

Oil Specifications:

• BMW 0W-30 LL01FE is specified for the N63R engine family
• Always replace the oil filter when changing your oil
• An oil change kit typically includes 10 quarts of synthetic oil and an OEM filter

Oil Change Guidance:

BMW's CBS system determines the optimal oil change interval based on driving conditions. Your 750i may need an oil change sooner if:

• The check engine/oil change light is on
• You hear knocking sounds from the engine
• You sense an oil smell in the cabin
• You see an excess amount of vehicle exhaust

Conservative Owner Guidance: More frequent oil changes may be needed if you regularly haul heavy loads, drive in dusty conditions, go off-roading, or drive at low speeds for long distances . In general, being extra-diligent about oil changes won't hurt your BMW—each oil change is another chance to check and resolve other car issues, such as worn brake pads or tire treads .

Oil Change Fill Procedure: Fill with approximately 8.5 quarts, test drive, check the level through iDrive, and add more if needed—do not pour all 10 quarts in at once .

Spark Plug Service

The N63R V8 engine uses high-performance spark plugs to ignite the fuel-air mixture. The 2016 BMW 750i uses 8 spark plugs .

Service Interval: For N63R V8 engines, BMW recommends replacing the spark plugs every 30,000–40,000 miles . Spark plugs are an essential maintenance item, especially if your BMW has been tuned for increased performance .

OEM Spark Plug Part Number: Genuine BMW spark plug part number 12120057704 is specified for the N63R engine .

Ignition Coils: Ignition coils can last 80,000–100,000 miles, but can also fail much sooner. Proactive replacement is recommended by the 90,000-mile mark .

Spark Plug Guidance:

Spark plugs are key to the performance and efficiency of your BMW engine. A bad plug(s) will harm performance and fuel mileage and affect drivability and engine smoothness. Unburnt fuel in the exhaust will shorten the lifespan of oxygen sensors and catalytic converters .

Symptoms of Faulty Spark Plugs:

• Shaking while the engine is idling
• Poor fuel economy
• Engine knocking
• Illuminated check engine light
• Misfiring

Oxygen Sensor Service

Service Interval: Oxygen sensors are scheduled for replacement at 120,000 miles, with a repeat service at 150,000 miles . Replacement helps maximize fuel economy and minimize exhaust pollution.

Brake Fluid Service

Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of your braking system . The 2016 BMW 750i uses DOT4 specification brake fluid (meeting DOT 5.1, DOT 4, and DOT 3 specifications) .

Fluid Specifications:

• Dry Boiling Point: 270°C (518°F)
• Wet Boiling Point: 185°C (365°F)

Service Interval: Brake fluid should be checked and changed when indicated by the CBS system. If you've noticed that your brake fluid appears black or brown, it's well past time for a service . In a normal system, the brake fluid is clear or very light gold in color; it darkens over time as it becomes contaminated .

Brake Fluid Flush: A brake system flush removes existing fluid and moisture from the system and replaces it with new, clean fluid. Brake fluid should be changed every time you service your brakes .

Estimated Service Cost: A brake fluid inspection for the 2016 BMW 750i xDrive is estimated at approximately $95 with $0 for parts and $95 for labor .

Brake System Service

BMW generally recommends that front and rear brakes are removed and serviced at least once every 12,000 miles or 12 months, including checking the parking brake .

Brake Pad Life: Brake pads often last 30,000 to 40,000 miles depending on driving style and conditions . If you drive mostly on the highway and tend to brake smoothly, your brake pads may last longer. Riding the brakes and hauling heavy loads can shorten their useful life .

Signs of Brake Issues:

• Unusual noises (squealing or grinding)
• Vibration or pulsation in the steering wheel or pedal
• A burning smell near the tires
• Illuminated brake dashboard warning light
• A feeling that something is "off"

Free Brake Inspection: Many service centers offer a complimentary brake check to help owners stay ahead of serious problems .

Battery Care

Batteries generally need to be replaced every three to five years . Depending on the climate where you live and your habits while driving, your 750i may need a replacement battery sooner. Taking short trips or exposing your car to extreme temperatures (like in the dead of winter or heat of summer) could reduce the life expectancy of your BMW battery .

Battery Warning Signs:

• Slow engine crank when starting
• Dim headlights
• Illuminated battery warning light

Long-Term Ownership Outlook

With proper and diligent maintenance, a 2016 BMW 750i could be on the road well past the 200,000 mile mark . Staying on track with routine service appointments can help your 750i perform better, keep you safer on the road, and help you avoid expensive repairs .

Regular maintenance is an investment that maintains the value and dependability of your car, extends its service life, and increases its resale value. Good maintenance should never be viewed as an expense—it is an investment in the longevity and reliability of your BMW.
