Understanding the 2017 BMW M6 Coupe (F13 Generation)

The 2017 BMW M6 Coupe is part of the F13 generation (LCI model year), powered by the S63 4.4L twin-turbo V8 engine. This high-performance grand tourer is available as a coupe and features BMW's sophisticated M-tuned chassis and drivetrain.

BMW's Condition Based Service (CBS) System

The 2017 M6 Coupe 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.

Service notifications appear on the Control Display when maintenance is due. This adaptive approach means your M6 may require service at different intervals than another vehicle of the same model, depending entirely on how it is driven.

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

Critical Service Bulletin: Oil Interval Reduction

A BMW service bulletin (B012418) states that on affected vehicles, the CBS engine oil service interval has been reduced to 1 year / 10,000 miles to make these vehicles consistent with all other N63x engine-equipped vehicles . This is a critical update for 2017 M6 owners.

Scheduled Maintenance Intervals

The following intervals represent factory-specified guidance for the 2017 BMW M6 Coupe, based on OEM service documentation . The CBS system remains the definitive authority for your specific vehicle's needs.

General Service Pattern

• Engine Oil & Filter: Determined by the CBS system, with a reduced interval of 1 year / 10,000 miles per service bulletin B012418
• Engine Air Filter: Replaced with every second engine oil change
• Cabin Air Filter (Microfilter): Replaced at every engine oil change
• Spark Plugs: Replaced with every second engine oil change
• Rear Axle Differential Oil: Replaced with each third engine oil change
• Brake Fluid: Replaced after 3 years for the first time, then every 2 years

Engine Oil Service

Factory Guidance and Service Bulletin Update

The S63 4.4L twin-turbo V8 engine requires BMW Longlife-approved fully synthetic oil. The oil capacity is approximately 8.5 quarts . A BMW service bulletin (B012418) reduced the CBS engine oil service interval to 1 year / 10,000 miles for the 2017 M6 .

Oil Specifications: BMW recommends oils meeting BMW LL-01 approval standards . Suitable oils include those with viscosity grades appropriate for your climate, as specified in your owner's manual.

Oil Filter: Always replace the oil filter simultaneously with an oil change. Motor oil is the single most important element in keeping your engine healthy .

Conservative Owner Guidance

While the reduced CBS interval is 1 year / 10,000 miles, some independent specialists recommend changing synthetic motor oil every 5,000 miles for optimal engine protection, particularly for high-performance S63 engines .

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 2017 M6 Coupe's S63 V8 engine requires spark plug replacement with each second engine oil change . The engine uses eight "High Power" spark plugs—part number 12120039634 .

Symptoms of Worn Spark Plugs:

• Rough idle
• Hesitation during acceleration
• Misfires under load
• Reduced fuel economy
• Check engine lights related to cylinder misfires

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 liter

Significance: Brake fluid is hygroscopic—it absorbs moisture from the atmosphere over time. This moisture accumulation lowers the fluid's boiling point, which can lead to brake fade during spirited driving. Hawk Performance recommends changing brake fluid every time you service your brakes .

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, enhancing engine efficiency and preventing 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.

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

The 2017 M6 Coupe is equipped with an M-specific dual-clutch transmission (M DCT). While the 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 2017 BMW M6 Coupe's S63 engine has several documented service bulletins that owners should be aware of :

Engine Oil Consumption (B110113): BMW has issued a bulletin addressing customer complaints that the engine's oil consumption is "too high," resulting in engine oil top-ups and workshop visits .

Valve Seal Replacement (B110117): A service bulletin provides 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 due to material not withstanding prolonged turbocharger temperatures .

Oil Leak from Rear of Engine (B110916): A bulletin addresses oil leaks from the rear of the engine and transmission bell housing on N63, N63TU, S63, and S63TU engines .

Crankcase Ventilation Hoses (B111216): A service action addresses checking and replacing crankcase ventilation hoses on N63T engines, as the hoses may become brittle and break when they come in contact with hot engine components .

High-Mileage Maintenance Planning

For 2017 M6 Coupe owners accumulating significant mileage:

60,000 Miles:

• Spark plug replacement
• Transmission fluid service (recommended by independent specialists for performance-driven vehicles)

120,000 Miles:

• Oxygen sensor replacement
• Spark plug replacement

150,000 Miles:

• Oxygen sensor replacement
