Engine Oil and Filtration Requirements
The heart of your 2023 BMW M5 is the 4.4-liter V8, an engine that generates significant heat and power. To keep it running smoothly, AMSOIL recommends the AMSOIL 0W-30 MS 100% Synthetic European Motor Oil. This oil is specifically engineered for gasoline, diesel, and hybrid European vehicles, offering precise protection against the high temperatures generated by the twin-turbo setup. It features a unique blend that ensures stability under extreme loads while maintaining excellent flow during cold starts.
The engine oil capacity for a 2023 BMW M5 with a filter change is 10.6 quarts. After refilling, it is critical to check the oil level to ensure the engine is properly protected. When performing the oil change, remember to torque the oil drain plug to 30 ft/lbs and replace the drain plug seal to prevent leaks. Pairing this oil with a WIX Oil Filter ensures that contaminants are effectively removed, extending the life of the engine and maintaining peak performance. The filter’s premium media outperforms many standard OEM-branded filters, providing superior filtration efficiency for this high-performance application.
Cooling System and Transmission Protection
The cooling system in the M5 is vital for managing the heat produced by the V8 engine. You have two excellent options for maintaining your cooling system: the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant. The pre-mixed version offers immediate use with a capacity of 12.2 quarts for a High-Temperature Coolant Change (HTCC) and 4.8 quarts for a Low-Temperature Coolant Change (LTCC), depending on the specific procedure. This formulation is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all cooling system metals and hoses. The concentrated propylene glycol option is an ideal choice for those who prefer to mix their own, offering a service interval of up to 150,000 miles or five years.
For the transmission, the 2023 M5 utilizes an 8-speed automatic transmission (GA8HP75Z). The total fill capacity for this transmission is 9.9 quarts. Using a dedicated synthetic transmission fluid is essential to prevent wear and sludge, especially under the stress of high-performance driving. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero conditions and provides reserve protection during periods of heavy use, ensuring smooth shifts and extended transmission life.
Brake Fluid and Essential Additives
Safety is paramount, and the braking system of the M5 requires high-quality fluid to function correctly. The vehicle requires a DOT 4 low viscosity fluid, specifically matching BMW part numbers 83 13 0 443 024 (0.5L) or 83 13 0 443 026 (1.0L). The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement, offering excellent responsiveness for ABS and traction control systems. It maintains stable viscosity over a wide temperature range, ensuring consistent pedal feel and stopping power in all conditions.
To further enhance the performance and longevity of your vehicle’s fuel system, consider using the AMSOIL P.i. Performance Improver Gasoline Additive. This additive can restore up to 14% of lost horsepower and restores GDI fuel injectors to 100% flow rate after just one tank. It improves fuel economy and helps prevent the carbon buildup that can lead to pre-ignition knock, a critical feature for direct-injection engines like the one in the M5.
Maintenance Best Practices
Proper maintenance of the 2023 BMW M5 involves more than just swapping fluids. Owners should be aware that the engine oil capacity is 10.6 quarts when changing the filter. It is important to check the oil level after the refill. Regular inspection of fluid levels and quality is essential for this high-performance vehicle. If the vehicle is being stored for an extended period, using the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup, while the AMSOIL Engine Fogging Oil protects internal components from rust and corrosion during inactivity.
