Engine Oil Selection and Capacities
The heart of the 2016 Mercedes Benz S65 AMG is its formidable 6.0L 12-cylinder engine. To ensure this high-output powerplant receives the protection it needs, AMSOIL recommends two specific European motor oil grades that cover various temperature conditions. The engine requires 11.1 quarts of oil when performing a complete change with the filter included. After refilling, it is crucial to check the oil level to ensure optimal filling.
Owners should torque the oil drain plug to 22 ft/lbs to ensure a proper seal without damaging the threads. The recommended viscosities are 0W-40 and 5W-40, suitable for all temperature ranges. The AMSOIL 5W-40 FS 100% Synthetic European Motor Oil is designed for drivers who need robust protection against the unique demands of European vehicles, featuring a blend that maintains stability under extreme heat. For colder climates or those seeking maximum flow during cold starts, the AMSOIL 0W-40 FS 100% Synthetic European Motor Oil offers superior low-temperature fluidity while maintaining high-temperature protection.
While no specific oil filter recommendations are currently available in the immediate product listing for this exact configuration, the fluid itself provides a high degree of detergency and wear protection, allowing for extended service intervals compared to conventional oils. This synthetic formulation is particularly beneficial for turbocharged engines like the S65 AMG’s, where thermal breakdown is a primary concern.
Transmission Fluid for the 7-Speed System
The 2016 S65 AMG is equipped with a sophisticated 722.932 transmission. Proper lubrication here is vital for shift quality and longevity, especially given the immense torque output of the S65 engine. The fluid capacity for a total fill of the 7-speed 722.932 transmission is 9.5 quarts.
It is important to distinguish between the transmission variants. For models with the A89 code (Reduced-Friction), the AMSOIL recommendation focuses on maximizing fluid efficiency. For models without the A89 code, protection against wear remains the primary focus. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is an excellent choice for this application. It withstands the rigors of heavy towing, elevated temperatures, and challenging terrain. Conversely, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers a robust, wear-protective solution that meets the exacting standards of the transmission’s design.
Cooling System and Brake Fluid Specifications
Maintaining the thermal efficiency of the S65 AMG is equally critical. The cooling system requires a total of 11.3 quarts of antifreeze and coolant. AMSOIL offers two distinct options to suit different owner preferences. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a ready-to-use ethylene glycol 50/50 pre-mix. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all cooling system metals and hoses without causing degradation.
For those who prefer a concentrated product that allows for precise mixing ratios, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a high-performance alternative. It requires mixing with distilled or high-quality water but offers protection up to 150,000 miles in passenger cars. This product is noted for greatly surpassing standards for metallic corrosion and erosion.
Brake fluid is another critical component often overlooked until a problem arises. The 2016 S65 AMG requires a brake fluid compatible with MB Sheet 331.0, specifically DOT 4 plus or products meeting the 0009895605090109 specification. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. Its stable viscosity ensures consistent braking performance regardless of extreme temperature fluctuations, making it a superior choice over traditional glycol-ether based fluids.
Additional Maintenance and Protection Products
Beyond the primary fluids, the S65 AMG owner may benefit from additional AMSOIL products for seasonal storage or system cleaning. For vehicles being stored for extended periods, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting ethanol corrosion. For engine protection during storage, AMSOIL Engine Fogging Oil is a highly effective rust preventive that coats internal components.
To maximize performance and fuel economy, AMSOIL P.i.® Performance Improver is a gasoline additive that restores up to 14% horsepower and cleans fuel injectors to 100% flow rate. For those concerned with rust on exterior metal surfaces, AMSOIL Heavy-Duty Metal Protector leaves a long-lasting protective coating. Finally, general maintenance tasks are simplified with products like the AMSOIL Engine Degreaser for cleaning grime from the engine bay and AMSOIL Brake and Parts Cleaner for ensuring clean, quiet braking components.
