Engine Oil and Filter Specifications
Maintaining the 2016 Mercedes-Benz GLE550E requires precise attention to fluid capacities and viscosity grades. The engine, identified by the code 276.82 P, is a 3.0L 6-cylinder unit that operates at high temperatures due to its turbocharged design. AMSOIL recommends using either the 5W-40 FS 100% Synthetic European Motor Oil or the 0W-40 FS 100% Synthetic European Motor Oil to ensure optimal protection. These viscosities cover a wide range of temperatures, suitable for both cold starts and extreme heat conditions. The specified engine oil capacity for the GLE550E is 7.4 quarts, including the filter replacement.
When performing an oil change, it is crucial to use a high-quality filter to match the longevity of the synthetic oil. The WIX Oil Filter (Product Code 57059-EA) is the recommended choice for this application. This filter is designed to trap contaminants effectively, ensuring that the clean oil circulates through the engine components. After refilling the oil, owners should always check the oil level to ensure it is within the correct range. The oil drain plug torque specifications are M12 at 22 ft/lbs and M14 at 22 ft/lbs, ensuring the plug is secure without risking damage to the oil pan. By utilizing AMSOIL’s European formula motor oil, drivers can benefit from a precise blend of synthetic base oils and premium additives tailored for gasoline, diesel, and hybrid European vehicles.
Transmission and Drivetrain Protection
The 2016 GLE550E is equipped with a 7-speed automatic transmission (model 724.204), which is a critical component for smooth power delivery in a hybrid vehicle. This transmission requires a specialized fluid that can handle the constant shifting and high torque output of the 3.0L engine. AMSOIL offers two primary options for this application. The Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid (Product Code ATLPK-EA) is designed for drivers who want maximum protection. It withstands heavy towing, elevated temperatures, and challenging terrain while maintaining fluidity in sub-zero conditions. The total fill capacity for this 7-speed transmission is 9.5 quarts, making a complete fluid change a substantial maintenance task that requires the correct fluid volume.
For those seeking an excellent balance of performance and value, the OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid (Product Code OTLQT-EA) is also a top-tier recommendation. It protects against wear and is formulated to meet the specific requirements of the transmission. Proper transmission fluid helps prevent sludge buildup and temperature-related problems, ensuring the 724.204 transmission operates reliably for years. Both fluids are engineered to provide a stable environment for the transmission’s internal components, enhancing the driving experience and extending the service life of the drivetrain.
Cooling System and Brake Fluid
Thermal management is vital for the 276.82 P engine, which generates significant heat. The cooling system requires a coolant that can prevent freezing in winter and boiling in summer while protecting the various metals and gaskets within the engine block. The GLE550E utilizes a hybrid cooling system that may involve high-temperature (HTCC) or low-temperature (LTCC) circuits. The recommended capacity for the high-temperature circuit is 10.2 quarts, while the low-temperature circuit requires 6.3 quarts.
AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix ethylene glycol formulation that offers protection up to 150,000 miles or 5 years. It is free of phosphates, nitrates, nitrites, silicates, borates, and amines, making it safe for all cooling system metals and components. For a longer service interval, AMSOIL Propylene Glycol Antifreeze and Engine Coolant is available. This concentrated coolant, when mixed with distilled water, offers protection for up to 150,000 miles or 5 years in passenger cars and exceeds industry standards for metallic corrosion.
Brake safety is paramount in a heavy vehicle like the GLE550E. The brake system requires a fluid that maintains a stable viscosity over a wide temperature range to ensure responsive pedal feel. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets the stringent requirements for Mercedes-Benz vehicles, including specifications for DOT 4 plus and products approved on MB Sheet 331.0. This synthetic brake fluid enhances ABS and traction-control responsiveness, providing a stable braking performance in all weather conditions.
Vehicle Background and Performance
About the Vehicle
The 2016 Mercedes-Benz GLE550e represents a significant evolution in the brand’s SUV lineup, blending the rugged utility of a traditional off-roader with the advanced technology of a plug-in hybrid. This model is part of the Mercedes-Benz GLE Class, which serves as the company’s flagship for luxury mid-size SUVs. The “e” in the name denotes its electrified powertrain, featuring a 3.0-liter V-6 engine paired with an electric motor.
