• The vehicle uses DOT4 specification brake fluid; brake fluid that appears dark or brown indicates contamination and the need for immediate service .
• Brake system service is recommended at least once every 12,000 miles or 12 months, and brake pads typically last between 30,000 and 40,000 miles .
• Wheel alignment should be checked approximately every 6,000 miles or 6 months .

Understanding BMW's Condition Based Service (CBS) System

The 2016 BMW 650i Gran Coupe utilizes BMW's Condition Based Service (CBS) system, which adapts maintenance requirements based on your actual driving style rather than fixed schedules. The system uses sensors and algorithms that take into account the driving conditions of your vehicle to determine when maintenance is required. It adapts the amount of maintenance to your specific driving profile, considering factors such as trip length, engine temperature, and driving style.

Service information on required maintenance is stored in the vehicle's remote key fob. Your BMW Service Advisor can read this data to propose the precise maintenance procedures needed for your vehicle .

The CBS system monitors:

• Engine oil
• Brake pads (front and rear separately)
• Brake fluid
• Spark plugs
• Microfilter/activated-charcoal filter
• Vehicle check

OEM Factory Maintenance Schedule

The following maintenance intervals represent key factory-recommended milestones for the 2016 BMW 650i Gran Coupe. 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 and helping it to enjoy a long life. The 2016 650i Gran Coupe uses the N63 4.4L twin-turbo V8 engine with an oil capacity of 9.5 liters .

Oil Specifications:

• BMW-approved synthetic oil
• BMW has recommendations as to whether conventional or synthetic oil is the best motor oil for your vehicle
• The oil filter should be replaced with every oil change

Oil Change Guidance:

BMW's CBS system determines the optimal oil change interval based on driving conditions. Outside of BMW-recommended intervals, your 650i Gran Coupe may need an oil change if:

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

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, getting more frequent oil changes won't harm your BMW—each oil change is another chance to check and resolve other car issues, such as worn brake pads or tire treads .

Signs Your Vehicle May Need an Oil Change Sooner:

• Check engine/oil change light is illuminated
• Knocking sounds from the engine
• Oil smell inside the vehicle
• Excess amount of vehicle exhaust

Spark Plug Service

Spark plugs are vital components that provide the electric spark your engine needs to start . The 2016 BMW 650i Gran Coupe uses 8 spark plugs for its V8 engine. NGK Laser Iridium spark plugs are compatible with the 4.4L V8 engine .

OEM Interval: Spark plugs are recommended for replacement at 60,000 miles, with a repeat service at 120,000 miles .

Spark Plug Guidance: Some service providers recommend replacing spark plugs on time or about every 30,000 miles . Replacing spark plugs on time is important to ensure proper engine performance and prevent starting issues .

Signs Your Engine May Need a Tune-Up:

• Shaking while the engine is idling
• Poor fuel economy
• An illuminated check engine light on your dashboard
• A knocking sound when the engine is running

Oxygen Sensor Service

OEM 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 650i Gran Coupe requires DOT4 specification brake fluid .

Fluid Guidance: Brake fluid should be changed every time you service your brakes . If you notice that your brake fluid appears black or brown, it is well past time for a service . Dark colors indicate significant contamination and moisture absorption, which reduces the system's ability to build pressure and compromises braking performance.

Brake Fluid Specifications:

• DOT4 specification
• Hawk Performance DOT4 premium specification brake fluid is available

Brake System Service

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

Brake Pad Life: Brake pads often last between 30,000 and 40,000 miles depending on driving style and conditions. Factors like driving mostly on highways and braking smoothly can help brake pads 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 pedal or steering wheel
• A burning smell near the tires
• Illuminated brake dashboard warning light
• A sensation that things aren't like they used to be

Wheel Alignment

Wheel alignment should be checked approximately every 6,000 miles or 6 months, whichever comes first .

Signs Alignment May Need Attention:

• A feeling that your car pulls to one side
• Rapid or uneven wear on one or more tires
• A steering wheel that feels off center or crooked while driving straight
• Tires that squeal frequently

Unlike with other potential issues, you won't see any dashboard warning lights if your wheel alignment is off .

Ignition Coils

Ignition coils transform battery voltage into the high energy needed for each spark plug. Weak coils or worn plugs cause misfires, rough idle, hard starts, and poor mileage . Ignition coils are not typically considered a scheduled maintenance item but may require replacement if they fail. They should be replaced as a full set when individual coils fail.

Air Filter and Cabin Filter Service

For driving in dusty conditions, the air filter should be inspected more frequently and replaced when visibly dirty. The cabin microfilter removes pollen, dirt, and harmful airborne pollutants from cabin air. Clogged cabin filters restrict airflow through the heater and air conditioner, reducing HVAC efficiency. Replacement intervals are determined by the CBS system.

Transmission and Differential Service

The 2016 650i Gran Coupe is equipped with an automatic transmission. BMW's original maintenance schedule classifies the transmission fluid as "lifetime fill" under normal conditions.

Conservative Owner Guidance: A conservative maintenance approach is to service the transmission as preventative maintenance at regular intervals to avoid potential failure. If left unserviced, the automatic transmission fluid will break down over time, potentially leading to poor shifting, slipping, and ultimately transmission failure.

The rear differential uses synthetic gear oil. BMW recommends exchanging differential fluids at certain intervals with BMW-approved products.

Long-Term Ownership Outlook

With proactive maintenance, the 2016 BMW 650i Gran Coupe has a good chance of hitting 200,000 miles or more. Staying on track with routine service appointments can help your 650i Gran Coupe perform better, increase your vehicle safety, 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.
