Understanding the 2009 BMW M5 (E60 Generation)

The 2009 BMW M5 is part of the E60 generation, powered by the legendary S85B50 5.0L naturally aspirated V10 engine . This engine is a milestone in BMW's history—derived from Formula 1 technology, it produces 500 horsepower at 7,750 rpm and features a high-revving, high-compression design .

The E60 M5 is known for its screaming exhaust note and 200-mph potential, but it demands meticulous maintenance. Unlike many modern BMWs that rely on Condition Based Service (CBS), the 2009 M5 follows a more traditional preventive maintenance schedule that independent specialists strongly recommend following .

BMW Ultimate Service & Warranty Coverage

The 2009 BMW M5 includes BMW's Ultimate Service program, which provides complimentary scheduled maintenance for 4 years or 50,000 miles from the vehicle's original in-service date . This coverage includes:

• Engine oil and filter changes
• Brake fluid flushes
• Spark plug replacements
• Cabin microfilter replacements
• Vehicle checks

The vehicle also carries a standard 4-year/50,000-mile new vehicle warranty and a 4-year/unlimited-mileage roadside assistance program.

Scheduled Maintenance Interval Summary

The following intervals represent factory-recommended and enthusiast-proven maintenance for the 2009 BMW M5. A conservative, preventive approach is strongly recommended for the S85 engine.

Break-In Service (1,200 Miles)

The 2009 BMW M5 requires a mandatory break-in service at approximately 1,200 miles . This service is critical for the long-term health of the S85 V10 engine and drivetrain components. During this initial visit:

• Engine oil and oil filter are replaced
• Differential fluid is replaced
• Transmission fluid is replaced

This break-in service is covered under BMW Ultimate Service. Owners should not delay this service, as proper break-in procedures affect engine longevity and performance.

Break-In Driving Guidelines

During the break-in period, BMW specifies careful operation:

• Keep engine speeds moderate; avoid high RPM operation
• Avoid full-throttle acceleration and kickdown
• Vary engine speeds and road speeds
• Do not use Launch Control

Engine Oil Service

Factory Guidance

The S85 V10 engine requires a specific high-performance oil due to its high-revving nature and tight bearing clearances. BMW recommends 10W-60 "TWS" oil, originally supplied by Castrol and now by Shell as BMW M TwinPower Turbo 10W-60 . This oil provides critical protection for the engine's bearings and valvetrain at extreme temperatures.

Oil Capacity: Approximately 9.3 to 9.8 liters with filter .

Approved Brands:

• BMW M TwinPower Turbo 10W-60 (current OEM)
• Castrol TWS Motorsport 10W-60 (original OEM)
• RAVENOL RSS SAE 10W-60
• Red Line 10W-60

The oil filter should always be replaced simultaneously with an oil change.

Conservative Owner Guidance

While the BMW Ultimate Service program may suggest intervals of 10,000-15,000 miles, enthusiasts and independent specialists strongly recommend more frequent oil changes for the S85 engine.

ECS Tuning recommends oil changes every 5,000-10,000 miles, depending on driving habits . Turner Motorsport offers a 5,000-mile oil service package, reflecting the strong enthusiast consensus for shorter intervals .

A more conservative 5,000-mile interval is widely recommended for:

• Track use or aggressive driving
• Short-trip driving patterns
• High-mileage vehicles

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 2009 BMW M5's S85 V10 engine requires spark plug replacement at 37,000-mile intervals . This interval is shorter than many BMW models because the S85 engine uses an ionic sensing system—the spark plugs act as combustion sensors that help the DME (engine control unit) adjust timing. As spark plugs wear, they can send false readings to this system, causing performance issues.

The engine uses 10 spark plugs (two per cylinder, as it is a V10). The OEM NGK plug is the recommended replacement.

Factory Replacement Schedule:

• 37,000 miles
• 74,000 miles
• 111,000 miles
• 148,000 miles

Symptoms of Worn Spark Plugs

• "Engine Fault" codes that may seem intermittent
• Reduced performance
• Increased emissions
• Rough idle

At the 60,000-mile major service, independent specialists also recommend inspecting and replacing ignition coils and coil boots .

Brake Fluid & Brake Inspection

Factory Guidance

Brake fluid flush/bleeding is included in the 30,000-mile major service according to enthusiast schedules . Brake fluid should be replaced on a time-based schedule as well, typically every 1-2 years .

Brake Inspection

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

• Inspecting brake pads (replace when material reaches approximately 3mm)
• Inspecting brake rotors for scoring, wear, or warping
• Checking the parking brake operation
• Inspecting brake lines and calipers

Signs of brake problems include :

• Unusual noises from the brakes
• Vibration or pulsation in the pedal or steering wheel
• Burning smell around the tires
• Dashboard brake light illuminated
• A sensation that braking performance has changed

Transmission & Differential Service

Factory Guidance

The 1,200-mile break-in service includes both transmission fluid and differential fluid replacement .

For ongoing maintenance, independent specialists recommend :

• Transmission fluid change: 30,000-mile intervals
• Differential fluid change: 30,000-mile intervals

Turner Motorsport's 30,000-mile major service package includes transmission fluid change using Red Line ATF-D4 or Motul Multi ATF, and differential fluid change using Red Line 75/140 or Motul GearComp 75/140 .

Engine Air Filter & Cabin Air Filter

Independent specialists recommend inspecting the engine air filter and cabin air filter (microfilter) at regular intervals, with replacement as needed .

• Engine air filter: Inspect and replace/clean as needed
• Cabin air filter (microfilter): Replace at recommended intervals to maintain HVAC efficiency

Turner Motorsport's annual service package includes cabin microfilter replacement and air filter cleaning or replacement .

Fuel Filter

The fuel filter is included in Turner Motorsport's 30,000-mile major service package . A clean fuel filter ensures fuel flow remains unobstructed, protecting fuel injectors and maintaining proper combustion.

60,000-Mile Major Service

At 60,000 miles, independent specialists recommend a comprehensive service package :

• Spark plug replacement
• Ignition coil and coil boot inspection and replacement
• Engine oil change with BMW 10W-60 oil
• Air filter replacement/cleaning
• Transmission fluid change
• Differential fluid change
• Brake fluid flush/bleeding
• Fuel filter replacement
• Engine and A/C serpentine belt replacement
• Belt roller pulley and belt tensioner replacement
• Full chassis inspection (control arms, tie rods, ball joints, wheel bearings, trailing arm bushings, subframe mounts, axle shaft boots)
• Complete brake system test and inspection
• Engine and transmission leak detection

Oxygen Sensors

The factory maintenance schedule for the 2009 BMW M5 indicates oxygen (O2) sensor replacement at 120,000 miles . A failing oxygen sensor can harm performance and fuel mileage and affect drivability.
