The 2016 BMW 750i features a 4.4-liter V8 engine with the engine code N63B44B. This unit is equipped with a 4-turbo system, necessitating an oil grade of 0W-30 that can handle all temperature extremes. The engine oil capacity is 10.6 quarts when a filter replacement is included. For the oil change procedure, the drain plug torque specification is 18 ft-lbs, and owners should replace the drain plug seal with every service. After refilling, it is critical to check the oil level to ensure proper lubrication throughout the engine block. The engine cooling system requires 9.7 quarts of coolant. Owners have two excellent options for this: the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant. The former is an ethylene glycol pre-mix that is ready to use and compatible with all cooling system metals and hoses. The latter is a concentrated formulation that requires mixing with distilled water and offers protection for up to 150,000 miles or five years.
Automatic transmission maintenance is equally critical for this model, which utilizes the GA8HP75Z transmission. While the specific fluid requirements are tight, AMSOIL offers two distinct synthetic automatic transmission fluids that meet these standards. The Signature Series is engineered for drivers who push their vehicles hard, offering reserve protection during heavy use and providing the fluidity necessary for rapid shifting even in freezing temperatures. The OE Fuel-Efficient version offers comparable wear protection and is a highly rated choice for maintaining transmission health over the long term. Beyond the engine and transmission, the braking system of a luxury sedan like the 750i demands the highest quality hydraulic fluid to maintain safety. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is a recommended choice, offering a stable viscosity that resists boiling under hard braking, which is essential for a vehicle of this speed and weight. For the rear differential, a capacity of 1.9 pints is specified for the transfer case lubricant, ensuring smooth power delivery to the wheels.
Additional Protection and Maintenance Fluids
Beyond the essential mechanical fluids, a 2016 BMW 750i can benefit from a comprehensive regimen of additional lubricants and chemical treatments. For owners who utilize the vehicle for shorter trips or plan on seasonal storage, AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing the varnish and gum buildup that can clog injectors. During extended periods of inactivity, AMSOIL Engine Fogging Oil provides a vital layer of rust prevention on internal engine components, safeguarding the complex valve train and bearings. For those looking to maximize fuel economy and restore lost power due to carbon buildup, AMSOIL P.i.® Performance Improver Gasoline Additive is a highly effective solution. This additive restores up to 14% horsepower and brings GDI fuel injectors back to 100% flow rate after just one tank, helping to reduce the need for higher-octane fuel and controlling pre-ignition knock.
Further up the lubrication spectrum, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor works to lubricate the fuel system and upper cylinders, adding an extra layer of protection for the valve stems and guides. For general vehicle maintenance, the AMSOIL Synthetic Multi-Purpose Grease offers exceptional performance with low-temperature pumpability and outstanding adhesive properties, making it ideal for chassis lubrication points that may be exposed to harsh road conditions. Protecting the vehicle’s exterior metal surfaces from the elements is also a key maintenance step; the AMSOIL Heavy-Duty Metal Protector creates a long-lasting, wax-like amber coating that resists salt, moisture, and chemical corrosion. For owners dealing with rusted components or seized bolts, the AMSOIL MP Metal Protector is a powerful solvent that cuts through rust, displaces water, and lubricates moving parts, helping to free frozen components and stop squeaks. For daily cleaning and care, a variety of products are available, including the AMSOIL Silicone Spray for rubber protection, the AMSOIL Heavy-Duty Degreaser for removing grime from engine surfaces, and the AMSOIL Power Foam® Carburetor and Induction-System Cleaner for cleaning intake systems. The vehicle’s appearance is also important to BMW owners, with options like the AMSOIL Miracle Wash Waterless Wash and Wax Spray, the AMSOIL High-Foam Car Shampoo, and the AMSOIL Exterior Ceramic Spray ensuring the paintwork remains pristine. For interior care, the AMSOIL Interior Detailer – Light Lemon or AMSOIL Interior Detailer – Scent Free provide 90-day UV protection and trap odors, keeping the cabin fresh and protected.
