Introduction: Understanding Your 2013 750Li xDrive's Service Requirements

The 2013 BMW 750Li xDrive is the long-wheelbase flagship of the F02-generation 7 Series, powered by the N63TU (N63B44) 4.4-liter twin-turbocharged V8 engine. This model features BMW's xDrive all-wheel-drive system for enhanced traction and handling.

BMW employs a Condition Based Service (CBS) system that monitors driving habits, coolant temperatures, engine speeds, trip length, and number of vehicle starts to determine when maintenance is required . Service reminders appear in the instrument cluster and iDrive display when maintenance is due, adapting the service schedule to your individual driving profile.

This guide presents the verified OEM maintenance schedule for the 2013 750Li xDrive alongside conservative owner-recommended intervals.

BMW Factory Maintenance Schedule

Verified Service Intervals

Based on available OEM documentation and manufacturer guidance, the following factory-recommended intervals apply to the 2013 BMW 750Li xDrive:

Condition Based Service (CBS) System

The 2013 750Li 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 . The vehicle also includes a service interval warning as standard equipment .

Engine Oil Change Guidance

Factory Requirements

The 2013 750Li xDrive uses BMW's Condition Based Service system to determine oil change timing based on actual driving conditions rather than a fixed mileage interval.

BMW Service Bulletin Confirmation: A BMW Service Information bulletin specifies that for N63 and N63TU engines in the 750Li (excluding ActiveHybrid models), the correct engine oil refill capacity is 9.5 quarts (9.0 liters) of engine oil . This specification applies to all future engine oil maintenance services and repairs that require draining and refilling the engine oil. The ActiveHybrid models are excluded because their hybrid engine oil pan dimensions are smaller .

Oil Specifications

The N63TU engine requires synthetic oil meeting BMW Longlife-01 (LL-01) specifications. BMW's engine oil quick reference chart for model years 2012 to 2015 specifies 0W-30 LL01FE for N63 and N63TU engines . Alternative viscosities such as 5W-30 and 5W-40 may also be suitable if they meet LL-01 approval.

The oil filter kit includes the filter and cap o-rings. Mahle is an OE supplier to BMW for these components .

Conservative Owner Recommendations

The N63 turbocharged V8 operates at high temperatures, making oil quality and regular changes essential. Many independent specialists recommend more frequent changes than the CBS system may indicate:

• 5,000-7,500 miles for severe driving conditions or performance-oriented use
• Annual changes even when mileage is low
• Regular oil level monitoring between changes

Signs that your 750Li xDrive may need an oil change sooner than scheduled include illuminated check engine or oil warning light, engine knocking sounds, oil smell inside the vehicle, or excessive exhaust output .

Spark Plug Replacement

Factory Schedule

The 2013 BMW 750Li xDrive's spark plugs are officially scheduled for replacement at 60,000 miles . Since its introduction, BMW has recommended a 60,000-mile replacement interval for N63 engine spark plugs . The N63 engine requires eight spark plugs.

A worn spark plug 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 .

Replacement Considerations

• Use BMW-approved spark plugs designed for the N63 engine
• Replacement should be performed by a qualified technician with proper tools

Conservative Owner Recommendations

Some 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

Oxygen Sensor Replacement

The factory schedule specifies oxygen sensor replacement at:

• 120,000 miles
• 150,000 miles

Replacing oxygen sensors at these intervals helps maintain fuel efficiency and emissions performance. Unburnt fuel from worn spark plugs can shorten oxygen sensor lifespan .

Brake Service Recommendations

Brake Inspection Interval

BMW recommends that front and rear brakes be disassembled and serviced at least once every 12,000 miles or 12 months . This inspection includes:

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

Brake Pad Lifespan

Brake pads generally last between 30,000 and 40,000 miles . Factors that affect brake pad lifespan include:

• Driving style (highway driving extends life; aggressive braking shortens it)
• Terrain and road conditions
• Load hauling

Signs of Brake Problems

Watch for these symptoms indicating brake service may be needed :

• Unusual noises when braking
• Vibrating pedal or steering wheel
• Burning smell from the tires
• Dashboard brake warning light
• A feeling that something is not right

Brake Fluid

Brake fluid service is monitored by the CBS system . Brake fluid absorbs moisture over time, which can reduce braking performance and cause corrosion in the brake system.

Transmission Service Guidance

BMW recommends having the transmission system routinely inspected for wear and tear. Specifically, differential and transmission fluids should be exchanged at regular intervals with BMW-approved products . A general guideline is to have transmission fluid checked and changed about every 30,000 to 60,000 miles, though this timeline can change depending on driving conditions .

Transmission Warning Signs

Be alert for these symptoms indicating potential transmission issues:

• Shifting delays or harsh shifts
• Grinding or jumping during acceleration
• Shakiness or vibration
• Whistling noises
• Burning smell from under the hood
• Decreased fuel economy
