2013 BMW 550i Maintenance Schedule & Service Intervals

Key Takeaways

• The 2013 BMW 550i is powered by the N63TU 4.4L twin-turbo V8 engine and belongs to the F10 chassis family. BMW issued a Service Action for this model year to program the CBS engine oil service interval to 1 year/10,000 miles .
• BMW utilizes a Condition Based Service (CBS) system that uses sensors to calculate maintenance needs based on actual driving conditions rather than fixed intervals .
• Spark plugs are recommended for replacement at 60,000 miles .
• Oxygen sensors are scheduled for replacement at 120,000 miles, with a repeat service at 150,000 miles .
• The N63 engine requires BMW-approved synthetic oil meeting Longlife specifications.

Understanding BMW's Condition Based Service (CBS) System

The 2013 BMW 550i utilizes BMW's Condition Based Service (CBS) system, which uses sensors and special algorithms to take into account the driving conditions of your vehicle and determine maintenance requirements . The system adapts the amount of maintenance to your specific user profile.

Service information is continuously stored in the vehicle's remote control. Your service center will read out this data and suggest the appropriate service procedures for your vehicle . The longest interval allowed between services is two years .

Important Note on N63TU Oil Service Interval: BMW issued a Service Action for 2013 model year vehicles equipped with N63TU engines (5, 6, and 7 Series produced from 07/2012 to 07/2013) to ensure the CBS engine oil service interval is programmed to 1 year/10,000 miles, making these vehicles consistent with all other N63x engine-equipped vehicles . Verify with your BMW service center that this update has been performed.

OEM Factory Maintenance Schedule

The following maintenance intervals are based on available documentation for the 2013 BMW 550i:

Engine Oil and Filter Change

The 2013 550i is powered by the N63TU 4.4L twin-turbo V8 engine. Following the BMW service action, the CBS oil service interval is set to 1 year/10,000 miles . The engine oil capacity is approximately 8.5 liters .

Oil Specifications:

• BMW Longlife approved synthetic oil
• Common viscosity: 5W-40
• Capacity: Approximately 8.5 L

Conservative Owner Guidance:

Motor oil is the single most important element in keeping your engine healthy . While BMW's CBS system determines individual intervals, Pelican Parts recommends changing synthetic motor oil every 5,000 miles . More frequent changes are advisable if you regularly:

• Haul heavy loads
• Drive in dusty conditions
• Drive at low speeds for long distances

Always replace the oil filter at every oil change . The N63 engine has documented oil consumption concerns—regular oil level monitoring is essential.

Spark Plug Service

The N63 V8 engine uses high-performance spark plugs, with the vehicle requiring 8 spark plugs.

Factory Interval:

BMW recommends spark plug replacement at 60,000 miles for the 2013 550i .

Spark Plug Specifications:

Just like ignition coils, 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 . Since its introduction, BMW has recommended a 60,000 mile replacement interval for N55/N63 spark plugs. There is no harm in doing it sooner, especially if other work is being performed in that area .

Oxygen Sensor Service

Factory Interval:

Oxygen sensors are scheduled for replacement at 120,000 miles, with a repeat service at 150,000 miles . Oxygen sensors deteriorate on a mileage basis and replacement helps maximize fuel economy and minimize exhaust pollution.

Brake Fluid

Conservative Owner Guidance:

Brake fluid should be flushed and replaced every 2 years regardless of mileage. Brake fluid is hygroscopic—it absorbs moisture from the atmosphere over time, which lowers its boiling point and compromises braking performance .

Brake System Service

BMW's CBS system features sensors on the brake pads that monitor wear. When pads wear down to a certain point, an indicator will appear on your dashboard . Brake pads typically last between 30,000 and 40,000 miles depending on driving style and conditions.

Transmission Service

The 2013 550i uses an 8-speed automatic transmission (8HP) . BMW's official maintenance schedule classifies this transmission as "lifetime fill" under normal conditions.

Conservative Owner Guidance:

ECS Tuning suggests performing a full service on your 8HP automatic transmission every 50,000 miles based on ZF's recommendations. If your vehicle is modified and makes more power than stock or if your vehicle is regularly track-driven, shorter 30,000-mile service intervals are recommended . This service should include:

• Transmission fluid drain and refill
• Transmission pan/filter replacement
• Fluid level reset using diagnostic equipment

Cabin Air Filter

Cabin air filters remove pollen, dirt, and harmful airborne pollutants from cabin air . Clogged cabin filters restrict airflow through the heater and air conditioner, reducing HVAC efficiency. Replace cabin filters at recommended intervals for best results .

High-Mileage Maintenance Considerations

For 2013 BMW 550i examples exceeding 60,000 miles, additional maintenance considerations become increasingly important.

N63 Engine-Specific Considerations

The N63TU V8 engine has several known maintenance considerations that owners should be aware of as the vehicle ages:

Valve Stem Seals:

The N63 engine is documented to have potential issues with valve stem seals, leading to oil consumption complaints. Symptoms include:

• Smoke from the tailpipe when starting the engine or during aggressive acceleration
• Excessive engine oil consumption

Cooling System:

The N63 engine uses a sophisticated cooling system. Routine inspection of cooling system components is recommended .

Timing Chain

The N63 engine uses a timing chain designed for the life of the engine. However, any unusual rattling noise on startup should be investigated promptly.

Battery Care

Batteries generally need to be replaced every three to five years. Short trips and extreme temperatures can shorten battery life.

Steering System

The steering system should be routinely inspected, including steering linkages, bushings, ball joints, and tie rod ends .

BMW Maintenance Program Coverage

For the 2013 model year, BMW offered the BMW Maintenance Program, providing free scheduled maintenance for 48 months or 50,000 miles from the original in-service date. For vehicles beyond this coverage, owners should plan for out-of-pocket maintenance.

Long-Term Ownership Outlook

With proper maintenance, a 2013 BMW 550i has a good chance of hitting 200,000 miles or more . However, the N63 V8 engine has documented issues that can be costly to maintain out of warranty. Owners concerned about the N63 engine's long-term reliability should follow a more conservative maintenance schedule, including 5,000-mile oil change intervals and regular oil level monitoring.
