Understanding the 2016 BMW M6 Convertible

The 2016 BMW M6 Convertible is the final model year of the F12 generation. It is powered by the S63B44T4 4.4L twin-turbo V8 engine, producing 560 horsepower in standard form. This high-performance grand tourer pairs a retractable hardtop with BMW's sophisticated M-specific chassis and drivetrain.

BMW's Condition Based Service (CBS) System

The 2016 M6 Convertible does not follow a traditional fixed-mileage maintenance schedule. Instead, it employs BMW's Condition Based Service (CBS) system . Sensors and algorithms monitor actual driving conditions—including engine temperature, driving style, trip length, and component wear—to determine when service is required. This system makes it possible to adapt the amount of maintenance to your individual driving profile .

Service notifications appear on the Control Display when maintenance is due. BMW service centers can read service data stored in the remote control to recommend the right scope of procedures .

Never ignore CBS alerts. Prompt attention to service notifications prevents minor issues from developing into costly repairs.

BMW Ultimate Care & Warranty Coverage

The 2016 BMW M6 Convertible includes comprehensive factory coverage from its original in-service date:

BMW Ultimate Care offers free scheduled maintenance during the first 3 years or 36,000 miles of ownership, including engine oil and filter changes, brake fluid, spark plugs, and vehicle checks . BMW TeleService "phones home" when your vehicle needs service .

BMW offers Ultimate Care+ for owners who intend to keep their car beyond the standard coverage period. The basic plan covers brakes (except Carbon Ceramic brakes), wipers, and clutch, with enhanced levels extending coverage to 7 years/125,000 miles .

Projected maintenance costs for the 2016 M6 Convertible show minimal expenses through the first four years, with a significant increase in year 5 as major services become due:

• Year 1: $155
• Year 2: $0
• Year 3: $0
• Year 4: $19
• Year 5: $2,510

Scheduled Service Intervals

The following intervals represent factory-specified guidance for the 2016 BMW M6 Convertible. The CBS system remains the definitive authority for your specific vehicle's needs.

Emission Control Maintenance

General BMW maintenance guidelines indicate:

• Spark Plug Replacement: Also at 60,000 miles
• Oxygen Sensor Replacement: General BMW schedules indicate 120,000-mile intervals

Engine Oil Service

Factory Guidance

The S63 4.4L twin-turbo V8 engine requires BMW Longlife-approved fully synthetic oil. The CBS system determines the exact oil change interval according to the service display .

Oil Approvals: BMW recommends oils meeting BMW LL-01 approval standards . Always verify the exact viscosity specification in your owner's manual, as different engines and climates require specific oil viscosities .

Oil Filter: Always replace the oil filter simultaneously with an oil change.

Conservative Owner Guidance

Pelican Parts notes that motor oil is the single most important element in keeping your engine healthy . While the CBS system may suggest intervals up to 10,000+ miles, Pelican recommends changing synthetic motor oil every 5,000 miles for optimal engine protection .

Signs that an oil change may be needed sooner include:

• Check engine/oil change light is on
• Engine knocking sounds
• Oil smell inside the vehicle
• Excess amount of vehicle exhaust
• Frequent dusty road driving, heavy loads, or low-speed driving for long distances

Spark Plugs

Factory Guidance

The 2016 M6 Convertible's S63 V8 engine requires spark plug replacement with each second engine oil change .

Genuine BMW Part Number: 12120039634

Quantity Required: The S63 4.4L V8 uses eight spark plugs (sold individually) .

Recommended Spark Plugs: This is a Motorsport-derived platinum plug designed for M engines, featuring a cold heat range for improved protection against misfires and knock .

OEM Suppliers: Bosch is a leading OEM supplier for BMW vehicles, and NGK also provides compatible plugs .

Conservative Owner Guidance

Spark plugs are key to the performance and efficiency of your BMW engine . Since its introduction, BMW has recommended a 25,000-mile replacement interval for S63 spark plugs . A bad plug(s) will harm performance and fuel mileage, affect drivability and engine smoothness, and unburnt fuel in the exhaust will shorten the lifespan of oxygen sensors and catalytic converters . Spark plugs wear out over a long time, making losses in performance less obvious .

Air Filters

Engine Air Filter

The engine air filter should be replaced with each second engine oil change . A clean engine air filter ensures optimal airflow for combustion and prevents contaminants from entering the engine.

Cabin Air Filter (Microfilter)

The cabin air filter (microfilter) should be replaced at every engine oil change . This filter removes pollen, dirt, and harmful airborne pollutants from the cabin air and maintains HVAC system performance.

Brake Fluid

Factory Guidance

Brake fluid replacement is a time-based, safety-critical service. BMW recommends replacing brake fluid after 3 years for the first time, then every 2 years thereafter .

Brake Fluid Specification: DOT 4 Class 6

Capacity: Approximately 1.06 US quarts

Significance: Brake fluid is hygroscopic—it absorbs moisture from the atmosphere over time. Air in the brake fluid causes braking to feel spongy and significantly reduces braking efficiency. BMW recommends changing brake fluid every time you service your brakes .

Rear Axle Differential Oil

The rear axle differential oil should be replaced with each third engine oil change . This service is particularly important for the M6's Active M Differential, which uses electronically controlled multi-plate clutches and requires specific oil grades.

Transmission Fluid Service

The 2016 M6 Convertible is equipped with an M-specific dual-clutch transmission (M DCT). The owner's manual provides guidance on transmission operation, including the automatic engagement of Park (P) when the ignition is switched off .

Service Consideration: While the BMW factory schedule does not specify a fixed interval for transmission fluid replacement under normal driving conditions, many independent specialists recommend transmission fluid changes at major service intervals for performance-driven vehicles. Check your owner's manual for the exact transmission fluid specification for your vehicle.

S63 Engine-Specific Service Bulletins

The 2016 M6 Convertible's S63 engine has documented service bulletins that owners should be aware of:

N63 & S63 Engine: Valve Seal Replacement (B110117): BMW has issued a service bulletin providing a new tool and procedure for replacing valve seals on S63TU engines. Excessive oil consumption, blue smoke on startup, or blue smoke during aggressive acceleration may indicate valve seal wear.

Turbocharger Coolant Lines (B110817): A service action bulletin addresses replacing turbocharger coolant lines on S63 engines, as the coolant lines may develop a leak over time.

Oil Leak from Rear of Engine (B110916): A bulletin addresses oil leaks from the rear of the engine and transmission bell housing.
