Understanding the 2010 BMW M5 (E60 Generation)

The 2010 BMW M5 is the final model year 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 modern BMWs that use Condition Based Service (CBS), the 2010 M5 follows a more traditional preventive maintenance schedule. The S85 V10 is an engine that does not forgive neglect . This guide emphasizes a conservative, preventive approach to keep this high-performance machine reliable .

BMW Ultimate Service & Warranty Coverage

The 2010 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 2010 BMW M5. A conservative, preventive approach is strongly recommended for the S85 engine .

Break-In Service (1,200 Miles)

The 2010 BMW M5 requires a dedicated 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 Castrol TWS Motorsport 10W-60 oil , which provides critical protection for the engine's bearings and valvetrain at extreme temperatures. This oil is approved for BMW M engines including the S85 .

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

Conservative Owner Guidance

While the BMW Ultimate Service program may suggest intervals up to 10,000 miles, enthusiasts and independent specialists strongly recommend more frequent oil changes for the S85 engine. Mike Miller's Old School Maintenance Schedule, widely respected in the BMW community, recommends oil and filter changes every 7,500 miles for the E60 M5 .

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

More frequent oil changes also give technicians more opportunities to catch and alert you to any issues, like worn brakes or a weak battery .

Spark Plugs

Factory Guidance

The 2010 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 increased emissions and performance issues .

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

Symptoms of Worn Spark Plugs

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

Brake Fluid & Brake Inspection

Factory Guidance

BMW recommends replacing brake fluid every 1-2 years regardless of mileage . The brake fluid capacity is approximately 1 liter, and DOT 4 Class 6 specification is required .

Brake Inspection

BMW recommends that front and rear brakes be removed and serviced at least once every 12 months or 12,000 miles . This includes inspecting the parking brake, brake pads, rotors, calipers, and brake lines .

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

Brake Pad Lifespan: Brake pads often last 30,000 to 40,000 miles , depending on driving style and terrain. Highway driving and smooth braking extend pad life, while heavy loads or frequent hard braking reduce it .

Engine Air Filter & Cabin Air Filter

Factory Guidance

Mike Miller's recommended schedule for the E60 M5 specifies:

• Engine air filter: Inspect every 15,000 miles, replace every 15,000-30,000 miles
• Cabin air filter (microfilter): Inspect every 15,000 miles, replace every 15,000-30,000 miles

A clean engine air filter ensures optimal airflow for combustion, enhancing engine efficiency and preventing contaminants from entering the engine . A clogged cabin filter restricts airflow through the heating and air conditioning system, reducing HVAC efficiency .

Fuel Filter & Drive Belts

Factory Guidance

Mike Miller's Old School Maintenance Schedule recommends:

• Fuel filter replacement: Every 60,000 miles
• Engine drive belts: Every 60,000 miles

Fuel filters ensure fuel flow remains clean and unobstructed, protecting fuel injectors and maintaining proper combustion .

Transmission & Differential Service

Factory Guidance

The 1,200-mile break-in service includes transmission fluid and differential fluid replacement . For ongoing maintenance, Mike Miller's schedule recommends:

• Transmission fluid (SMG & 6MT): Every 30,000 miles
• Differential oil: Every 30,000 miles

The SMG transmission also uses hydraulic fluid (Pentosin CHF 11.S) for the pump, which is separate from the transmission fluid and is changed with the power steering fluid .

Power Steering Fluid

Factory Guidance

Mike Miller's schedule recommends replacing the power steering fluid (Pentosin CHF 11.S) every 30,000 miles . This fluid also serves the SMG hydraulic pump on SMG-equipped models .

Rod Bearings: The Critical S85 Consideration

Enthusiast Guidance

The S85 V10 engine has a well-documented vulnerability regarding its rod bearings. Due to tight factory clearances and the high-revving nature of the engine, rod bearings are a known wear item on the E60 M5 . This is considered a critical maintenance item that transcends standard scheduling.

Mike Miller's Old School Maintenance Schedule recommends rod bearing replacement as early as 50,000 miles . This is a recommended preventive measure rather than a reactive repair. Symptoms of failing rod bearings include:

• Metallic knocking sounds from the engine, especially at cold start
• Metal particles in the oil filter
• Low oil pressure warnings

Many enthusiasts consider rod bearing replacement a mandatory preventive service for the E60 M5, similar to the E46 M3. The cost is significant, but it is far less than the cost of a full engine replacement .

Cooling System

Factory Guidance

Mike Miller's schedule recommends replacing engine coolant every 2 years using a 50/50 mix of BMW anti-freeze and distilled water . Regular monitoring of coolant levels is recommended.

The S85 engine's cross-flow cooling system is critical for maintaining proper operating temperatures . Any signs of coolant leaks should be addressed promptly. Regular inspection of hoses for cracks or bulging is recommended .

Oxygen Sensors & Hoses

Factory Guidance

Mike Miller's schedule recommends:

• Oxygen (O2) sensor replacement: 150,000 miles (or when a check engine light indicates failure)
• Water and fuel hoses: 150,000 miles

A failing oxygen sensor can harm performance and fuel mileage and affect drivability.
