Introduction: Understanding Your 2013 750i xDrive's Maintenance Requirements

The 2013 BMW 750i xDrive is a flagship luxury sedan powered by the updated N63TU 4.4-liter twin-turbocharged V8 engine. This F01-generation 7 Series delivers exceptional performance through its xDrive all-wheel-drive system. Proper maintenance is critical for preserving both performance and longevity.

The 2013 model year represents a significant update for the N63 engine family. Vehicles produced from 07/2012 to 07/2013 received the N63TU engine, which addressed some earlier reliability concerns .

BMW utilizes a Condition Based Service (CBS) system that monitors driving habits and mileage to determine when service is required. A formal BMW Service Action confirmed that the CBS engine oil service interval for N63TU-equipped vehicles has been standardized to 1 year or 10,000 miles . This change was implemented to ensure consistency across all N63 engine-equipped vehicles.

This guide presents the verified OEM maintenance schedule alongside conservative owner-recommended intervals for those seeking maximum vehicle longevity.

BMW Factory Maintenance Schedule

Verified Service Intervals

Based on available OEM documentation, the following factory-recommended intervals apply to the 2013 BMW 750i xDrive:

Condition Based Service (CBS) System

The 2013 750i xDrive relies on the CBS system to track maintenance needs through vehicle sensors that monitor:

• Engine oil condition based on driving style and distance
• Brake pad wear through electronic sensors
• Brake fluid age
• Spark plug service requirements
• Vehicle inspection intervals

Service reminders appear in the instrument cluster and iDrive display when maintenance is due.

Engine Oil Change Guidance

Factory Interval

For the 2013 BMW 750i xDrive's N63TU engine, the official oil change interval is 10,000 miles or 12 months, whichever comes first. This was formally established through a BMW Service Action affecting N63TU-equipped vehicles produced from 07/2012 to 07/2013 . The action standardized the interval across all N63 engine vehicles to maintain consistency.

This 10,000-mile interval applies to the F01, F02 (7 Series) vehicles produced in this timeframe .

Conservative Owner Recommendations

Many independent specialists and experienced owners recommend more frequent oil changes:

• 5,000-7,500 miles for severe driving conditions, heavy loads, or dusty environments
• Annual changes even when mileage is low
• 5,000-mile interval preferred for aggressive or city driving

The N63TU engine's turbocharged V8 design operates at high temperatures, making oil quality and regular changes essential for preventing:

• Turbocharger bearing wear
• Valve train deposits
• Timing chain tensioner issues
• Excessive oil consumption

Oil Specifications

The 2013 750i xDrive requires synthetic oil meeting BMW Longlife-01 specifications. Common viscosities include:

• 0W-30 (factory preference)
• 5W-30
• 5W-40 (popular for performance and warm climates)

Spark Plug Replacement Timing

Factory Schedule

The 2013 BMW 750i xDrive's spark plugs are officially scheduled for replacement at 60,000 miles . BMW has recommended this interval for the N63 and N55 engines since their introduction .

Conservative Owner Recommendations

Many owners choose earlier replacement to maintain optimal performance:

• 30,000-40,000 miles for performance preservation
• Replacement recommended when experiencing rough idle, misfires, or reduced fuel economy
• Replacement when ignition coils are serviced

The N63 engine's eight spark plugs are critical for smooth operation. Worn plugs can cause misfires, reduced performance, and decreased fuel efficiency. Unburnt fuel in the exhaust can shorten the lifespan of oxygen sensors and catalytic converters .

Replacement Considerations

When replacing spark plugs:

• Use BMW-approved OEM parts designed for the 4.4L V8
• Bosch supplies OE components for BMW vehicles
• Replacement should be performed by a qualified technician with proper tools for the N63 engine

Brake Service Recommendations

Brake Fluid Replacement

Brake fluid replacement follows the standard BMW schedule:

• BMW recommends changing brake fluid every two years for the 7-Series F01 generation
• Brake fluid should also be changed whenever brakes are serviced

Brake Inspection

BMW recommends that front and rear brakes be disassembled and serviced at regular intervals. This inspection includes:

• Brake pad wear assessment
• Brake rotor condition
• Parking brake inspection
• Brake fluid level and condition

Signs of Brake Problems

Watch for these symptoms indicating brake service may be needed:

• Weird noises when braking
• Vibrating pedal or steering wheel
• Burning smell near tires
• Dashboard brake warning light
• Changes in braking feel or response

Transmission Service Guidance

BMW's Official Position

BMW classifies the transmission fluid in the 750i xDrive as "lifetime fill." The factory maintenance schedule does not include routine transmission fluid changes under normal operating conditions .

Conservative Owner Recommendations

Despite BMW's lifetime designation, aftermarket specialists strongly recommend periodic transmission service:

• Transmission fluid and filter service is generally recommended for long-term reliability
• Fluid specification: Use BMW-approved transmission fluid

Transmission Fluid Specifications

For the 2013 750i xDrive, ZF automatic transmission fluid is compatible with Lifeguard 8 specification . This is a specialized oil optimized for the specific requirements of each brand and model of transmission, assisting in lubrication and operation of brake bands, torque converter, and valves .

Transmission Warning Signs

Be alert for these symptoms:

• Shifting delays
• Grinding when accelerating
• Shakiness or vibration
• Whistling noises
• Burning smell from under the hood
• Decreased fuel economy

Oxygen Sensor Replacement

The factory schedule specifies oxygen sensor replacement at:

• 120,000 miles
• 150,000 miles

Cooling System Maintenance

Coolant Replacement

BMW generally recommends coolant replacement every:

• 2-4 years or 30,000-50,000 miles
• Check your owner's manual for your particular model's recommendations
• Regular coolant level checks should be performed at least once a year or around every 12,000 miles

Importance of Coolant Maintenance

Changing the coolant in your BMW's cooling system is essential for its long-term health. Coolant may lose its efficacy and become tainted with contaminants over time . Frequent coolant changes preserve the effectiveness of the cooling system and stop corrosion and scale from accumulating inside the radiator and engine .

Cooling System Warning Signs

Watch for signs of cooling system issues:

• Leaking coolant
• Overheating
• Illuminated low coolant dashboard light

xDrive and Drivetrain Service

The xDrive all-wheel-drive system requires attention not always emphasized in the standard schedule:

• Transfer case fluid: Consider service at 60,000-mile intervals
• Differential fluid: Front and rear differential fluid changes at similar intervals

These components are often overlooked but critical for xDrive longevity.
