The 2016 Mercedes-Benz E550 is a sophisticated luxury sedan powered by a potent 4.7-liter twin-turbocharged V8 engine. This high-performance powerplant demands lubricants that can withstand extreme thermal stresses, high rotational speeds, and the rigorous demands of turbocharging. Standard mineral oils simply cannot provide the level of protection required for the precise tolerances found in this European engineering masterpiece. Using the correct synthetic lubricants ensures optimal lubrication, maximized horsepower, and extended component life, keeping the driving experience as smooth and responsive as the day it rolled off the assembly line.

Protecting a vehicle of this caliber requires more than just pouring oil into the engine; it requires a comprehensive approach to fluid maintenance. The 2016 E550 utilizes advanced engine management systems and tight-clearance turbochargers that generate immense heat. Without high-quality synthetic motor oil, the risk of sludge buildup, accelerated wear on camshafts and bearings, and potential thermal breakdown increases significantly. The recommended AMSOIL European formulations are designed to maintain their viscosity index even when the engine is pushed to its limits during spirited driving or track use.
Engine Oil and Filtration Requirements
The heart of the 2016 Mercedes-Benz E550 is the 4.7-liter V8, identified by engine code 278.922. This twin-turbocharged unit is known for its torque and responsiveness, but it also places high stress on lubrication systems during cold starts and high-load scenarios. The manufacturer specifies an oil capacity of 8.5 quarts, including the filter change. It is crucial to verify the oil level after the refill, as the turbochargers and internal galleries require precise fill levels to function correctly.
For this engine, AMSOIL recommends two primary viscosity grades depending on the climate and driving conditions. The 5W-40 FS 100% Synthetic European Motor Oil is ideal for most operating conditions, featuring a precise blend of synthetic base oils and premium additives tailored for European specifications. Alternatively, the 0W-40 FS 100% Synthetic European Motor Oil offers enhanced protection in sub-zero temperatures, ensuring that the oil reaches critical engine components almost instantly upon startup, reducing the wear that typically occurs during cold starts.
Filtration is equally critical. The WIX Oil Filter (Part 57059) is the recommended choice for this application. This filter utilizes premium media that offers improvements over original equipment manufacturer-branded filters in terms of filtration efficiency and capacity. By capturing contaminants effectively, the filter keeps the oil clean, which is essential for maintaining the lubricity and flow properties required by the V8’s complex oil control valves and turbocharger bearings.
Transmission and Cooling System Fluids
The transmission in the E550 is a 7-speed automatic unit (722.909) that requires a fluid capable of handling both high torque and the specific frictional properties needed for smooth shifting. AMSOIL offers the Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid, which is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero conditions, providing reserve protection during heavy use. There is also the OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid, which meets the stringent original equipment requirements and provides excellent wear protection for the transmission’s intricate clutches and gears.
For the cooling system, the capacity is 11.5 quarts. Maintaining the correct temperature balance is vital for the longevity of the aluminum block and heads. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that is engineered to exceed OEM requirements. It is free of phosphates, nitrates, nitrites, silicates, borates, and amines, which helps prevent scaling and deposits. For those preferring a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a non-toxic alternative that allows for custom mixing ratios. Both options provide protection up to 150,000 miles or 5 years, ensuring the engine does not overheat even under the most demanding driving conditions.
Brake Fluid and Seasonal Maintenance
Brake safety is non-negotiable. The E550 requires a high-performance brake fluid that can handle the heat generated during repeated hard stops. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent choice, offering excellent ABS and traction-control responsiveness. It provides a stable viscosity over a wide temperature range, preventing the fluid from boiling and causing brake fade. This fluid is compliant with the MB Sheet 331.0 requirements, ensuring it is safe for the vehicle’s sensitive braking sensors and valves.
For owners who store their vehicles seasonally, preventing internal corrosion and fuel degradation is essential. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting ethanol corrosion and preventing varnish buildup. Additionally, the AMSOIL Engine Fogging Oil provides a rust preventive coating for internal engine components during long periods of inactivity, protecting the cylinders and bearings from moisture accumulation.
