The 2022 Mercedes-Benz GLE63 AMG S is a high-performance luxury SUV that demands the highest quality lubricants to maintain its legendary reputation. Powered by the potent 4.0-liter twin-turbo V8 engine, this vehicle operates under extreme thermal and mechanical stress. Proper maintenance is not merely a suggestion for this machine; it is a critical requirement for ensuring longevity and performance. The unique demands of AMG engineering mean that standard mineral oils simply cannot provide the necessary protection against the high heat generated by the turbochargers or the specific requirements of European engines. Using fluids formulated specifically for these advanced systems ensures that the vehicle’s complex components remain lubricated, clean, and protected from wear.
Recommended AMSOIL Products
For the 2022 Mercedes-Benz GLE63 AMG S, AMSOIL offers top-tier synthetic solutions designed to meet or exceed the rigorous original equipment manufacturer (OEM) specifications required for this vehicle. The following products are recommended for optimal engine protection, cooling system performance, and vehicle longevity.

Engine Oil Specifications and Capacities
The heart of the 2022 GLE63 AMG S is the 4.0-liter V8 biturbo engine, identified by the engine code 177.980 C Turbo. This powerplant generates significant horsepower and torque, placing immense strain on the lubrication system. To ensure smooth operation and maximum service intervals, AMSOIL 5W-40 FS or AMSOIL 0W-40 FS synthetic motor oils are the ideal choice. The recommended oil viscosity for this engine includes 5W-40 or 0W-30 for use in all temperature ranges. For climates where temperatures remain above -25°C, 5W-30 is also an acceptable option.
The oil capacity for the engine is approximately 10 quarts when the oil filter is included during a change. It is crucial to adhere to these specifications to avoid under-lubrication or oil overflow. After refilling the oil system, owners should always check the oil level to ensure proper circulation. The torque specifications for the oil drain plug are equally important; for metal plugs, a torque of 15 ft/lbs is required, while plastic plugs should be torqued to 3 ft/lbs. Always ensure the drain plug seal is replaced during every service to prevent leaks.
Cooling System Maintenance
Efficient cooling is vital for the longevity of the 4.0L twin-turbo engine. Over time, antifreeze degrades, losing its ability to protect against corrosion and boil-over. The cooling system requires a specific capacity of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant to function correctly. Depending on the system configuration, the low-temperature coolant capacity (LTCC) is 5.3 quarts, while the high-temperature capacity (HTCC) is 16.6 quarts.
Using a high-quality antifreeze like the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant ensures that the cooling system remains free from rust and corrosion. This fluid is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it safe for all modern cooling system metals, gaskets, and hoses. For those who prefer mixing their own coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a concentrated solution that provides protection up to 150,000 miles or 5 years, whichever comes first.
Fuel System Care and Additives
Direct Injection (GDI) engines, such as the one found in the GLE63 AMG S, are highly susceptible to carbon buildup on fuel injectors and intake valves. This buildup can lead to reduced performance, rough idling, and increased fuel consumption. Regular maintenance with AMSOIL P.i. Performance Improver Gasoline Additive can restore fuel injectors to 100% flow rate after just one tank of fuel. This additive helps prevent carbon rap and controls pre-ignition knock, ensuring the engine runs smoothly and efficiently. Additionally, for vehicles that see seasonal use or are stored for extended periods, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup.
Transmission and Differential Considerations
While the 2022 Mercedes-Benz GLE63 AMG S typically utilizes specific OEM transmission and differential fluids, the use of high-performance lubricants can significantly enhance the durability of these components. The transmission and differential/transfer case fluids are critical for handling the immense torque output of the AMG powertrain. Although specific AMSOIL product recommendations for the transmission fluid are not currently available in the guide, maintaining the correct fluid levels and ensuring the fluid is free from sludge and temperature-related degradation is essential. Using superior synthetic lubricants helps protect against wear, ensuring the transmission and differential operate smoothly under the most severe driving conditions.
About the Vehicle: 2022 Mercedes-Benz GLE63 AMG S
The 2022 Mercedes-Benz GLE63 AMG S represents the pinnacle of luxury performance SUVs, blending the rugged utility of a large crossover with the raw power of a high-performance sports car. Built on the Mercedes-Benz MFA2 platform, this vehicle is a testament to German engineering excellence. Under the hood lies the M177 engine, a handcrafted, 4.0-liter V8 biturbo that produces an incredible amount of horsepower and torque, allowing the heavy SUV to accelerate with the ferocity of a sports sedan. The “S” designation denotes a further upgrade in power and handling characteristics compared to the standard GLE63, featuring a more aggressive tuning and enhanced suspension components.
Owners of the GLE63 AMG S often cite the vehicle’s ability to switch between a comfortable, everyday cruiser and a track-capable machine as its greatest appeal. The interior is equally impressive, offering top-tier materials, advanced infotainment systems, and a level of comfort that rivals many dedicated luxury sedans. Despite its size and performance, the GLE63 AMG S maintains a reputation for being relatively reliable when maintained properly. However, like any high-performance vehicle, it requires diligent care to avoid common issues.
One common challenge faced by owners of this specific model involves carbon buildup in the intake manifold and on the valves. Due to the Direct Injection (GDI) technology used in the M177 engine, fuel is injected directly into the combustion chamber rather than the intake port, which can lead to carbon accumulation on the intake valves over time. This buildup can restrict airflow and reduce engine efficiency. Regular use of high-quality fuel additives like AMSOIL P.i. Performance Improver can help mitigate this issue and keep the intake system clean.
Another area of concern for these high-output engines is thermal management. The intense heat generated by the biturbo setup places significant stress on the cooling system. Degraded coolant can lead to corrosion, overheating, and eventual failure of critical components. Ensuring the cooling system is flushed and refilled with a high-performance antifreeze like AMSOIL Propylene Glycol Antifreeze and Engine Coolant or AMSOIL Passenger Car & Light Truck Antifreeze & Coolant helps protect the aluminum components of the engine and radiator.
Additionally, the oil consumption rates in some of these high-performance engines can be higher than standard vehicles due to the tight tolerances and extreme operating temperatures. Using a high-quality, fully synthetic European-formulated motor oil like AMSOIL 5W-40 FS provides better high-temperature stability and film strength, reducing the likelihood of oil breakdown and consumption. Finally, the vehicle’s complex electronic suspension and air ride systems require specialized care. While the fluids for these systems are specific, keeping the vehicle clean and protecting the components with AMSOIL Engine Degreaser and AMSOIL Heavy-Duty Metal Protector helps maintain the integrity of the air suspension struts and bushings, preventing premature wear and noise. By addressing these specific needs with the right lubricants, owners can ensure their GLE63 AMG S continues to deliver its legendary performance year after year.
