• BMW's synthetic oil and filter changes typically occur every 10,000 miles or 12 months . Pelican Parts recommends changing synthetic motor oil every 5,000 miles for optimal engine protection .
• Brake fluid requires replacement after 3 years for the first time, then every 2 years thereafter . Fixed mileage milestones include 60,000-mile spark plug replacement and 120,000-mile oxygen sensor replacement .
• The S63 engine has a total oil capacity of 9.5 liters .

Understanding BMW's Condition Based Service (CBS) System

The 2013 BMW M6 Gran Coupe does not follow a traditional fixed-mileage maintenance schedule for its primary service intervals. Instead, it employs BMW's Condition Based Service (CBS) system . Sensors and special algorithms take into account the driving conditions of your vehicle—including engine temperature, driving style, trip length, and component wear—to determine maintenance requirements . The system makes it possible to adapt the amount of maintenance to your individual driving profile .

Service data is continuously stored in the remote control . Your service center will read out this data and suggest the right array of service procedures for your vehicle . Service requirements can be displayed on the Control Display .

Important Note on Storage Periods: Storage periods during which the vehicle battery was disconnected are not taken into account by the CBS system. If this occurs, have a service center update the time-dependent maintenance procedures, such as checking brake fluid and, if necessary, changing the engine oil and the microfilter/activated-charcoal filter .

BMW Ultimate Care & Warranty Coverage

The 2013 BMW M6 Gran Coupe 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, covering engine oil and filter changes, brake fluid, spark plugs, and vehicle checks . The vehicles carry a standard 4-year/50,000-mile warranty .

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

Scheduled Maintenance Intervals

The following intervals represent factory-specified guidance for the 2013 BMW M6 Gran Coupe, based on OEM service documentation . The CBS system remains the definitive authority for your specific vehicle's needs.

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 . BMW's synthetic oil and filter changes typically occur every 10,000 miles or 12 months, whichever occurs first .

Total Oil Capacity: 9.5 liters .

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 and helping it to enjoy a long life .

Conservative Owner Guidance

Pelican Parts recommends changing synthetic motor oil every 5,000 miles for optimal engine protection . Different engines and climates require specific oil viscosities—be sure to refer to your owner's manual for the type and viscosity of oil required for your car .

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
• Frequent dusty road driving, heavy loads, or low-speed driving for long distances

Spark Plugs

Factory Guidance

The 2013 M6 Gran Coupe's S63 V8 engine requires spark plug replacement with each second engine oil change , and at the 60,000-mile fixed interval . The engine uses eight spark plugs .

Symptoms of Worn Spark Plugs :

• Stalling or shaky idling when stopped
• Diminished fuel economy
• Knocking noises in the engine
• Illuminated check engine light

Brake Fluid

Factory Guidance

Brake fluid replacement is a time-based, safety-critical service. BMW recommends brake fluid replacement after 3 years for the first time, then every 2 years thereafter . BMW's general maintenance guidelines also list brake fluid changes at the 30,000-mile mark, then every 60,000 miles thereafter .

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 .

Brake Inspection: BMW suggests that rear and front brakes are removed and serviced at least once every 12 months or 12,000 miles . This includes checking the parking brake.

Brake Pad Lifespan: Brake pads often last 30,000 to 40,000 miles, depending on driving style and terrain .

Air Filters

Engine Air Filter

The engine air filter should be replaced with each second engine oil change according to the factory service schedule . 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 according to the factory service schedule . 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 according to the factory service schedule . This service is particularly important for the M6's Active M Differential, which uses electronically controlled multi-plate clutches and requires specific oil grades.

Fuel Filter

Fuel filters are typically changed every 20,000 to 40,000 miles according to general BMW maintenance guidance . This interval ensures fuel flow remains clean and unobstructed, protecting fuel injectors and maintaining proper combustion.

Oxygen Sensors

The factory maintenance schedule for the 2013 BMW M6 Gran Coupe indicates oxygen (O2) sensor replacement at 120,000 miles and again at 150,000 miles . A failing oxygen sensor can harm performance and fuel mileage and affect drivability.

Long-Term Ownership Considerations

High-Mileage Maintenance Planning

For 2013 M6 Gran Coupe owners accumulating significant mileage, additional services become relevant :

60,000-100,000 Miles:

• Transmission fluid service (recommended by independent specialists for performance-driven vehicles)
• Engine air filter replacement (if not already done at second oil change intervals)
• Cooling system inspection and possible flush

100,000+ Miles:

• Oxygen sensor replacement
• Full transmission service
• Comprehensive vehicle inspection

S63 Engine-Specific Maintenance

The S63 4.4L twin-turbo V8 is a high-performance engine that requires diligent maintenance. Key considerations include:

• Frequent Oil Changes: Frequent oil changes with high-quality synthetic oil are critical to maintaining turbocharger and engine health.
• Cooling System: The S63 generates significant heat, so regular inspection of the cooling system and replacement of coolant at specified intervals is necessary to avoid overheating.
• Valve Stem Seal Wear: Over time, worn valve stem seals can cause oil consumption issues, particularly in engines with higher mileage.
