Maintaining the 2023 Mercedes-Benz E350 with a 2.0-liter turbocharged four-cylinder engine requires fluids that meet rigorous European specifications. This vehicle’s engine code 264.920.9 benefits from synthetic lubricants designed to handle the high stresses of turbocharging while providing optimal protection in extreme temperatures. Using the correct viscosity and formula ensures the engine stays clean, reduces wear, and maintains fuel efficiency for years of reliable performance.
Recommended AMSOIL Products
For this specific engine, AMSOIL offers a range of European-specific motor oils that exceed OEM requirements. The capacity for an oil change with filter is 6.3 quarts for standard operation and 7 quarts if specific refill conditions apply. Below are the primary lubrication products recommended for your 2023 E350.
- AMSOIL 5W-30 LS 100% Synthetic European Motor Oil – Designed with a precise blend of synthetic base oils and premium additives specifically for gasoline, diesel, and hybrid European vehicles, offering superior protection under the unique demands of turbocharged engines.
- AMSOIL 5W-40 MS 100% Synthetic European Motor Oil – An excellent choice for vehicles operating in warmer conditions or high-mileage applications, providing robust film strength while maintaining fuel economy.
- AMSOIL 0W-20 LS 100% Synthetic European Motor Oil – Optimized for the lowest viscosity requirements of modern Euro vehicles, ensuring rapid oil flow during cold starts and maximum fuel efficiency.
- AMSOIL Passenger Car & Light Truck Antifreeze & Coolant – A unique OAT formulation compatible with all cooling system metals, providing protection up to 150,000 miles or 5 years for the 11.6-quart capacity required.
- AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid – Withstands heavy towing and elevated temperatures while remaining fluid in sub-zero conditions, ensuring smooth shifting and extended transmission life.
- AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid – A more economical choice for daily driving that still delivers essential wear protection.
- AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid – Offers excellent ABS responsiveness and stable viscosity across a wide temperature range, meeting the high standards required for Mercedes-Benz braking systems.
Proper fluid selection is critical for the longevity of the 2.0L engine. The turbocharger spins at incredibly high speeds, generating significant heat that breaks down conventional mineral oils quickly. By using 100% synthetic oil formulated for European standards, you ensure that the turbo bearings receive adequate lubrication even during high-load driving. Furthermore, the 5W-30 and 5W-40 options cover a broad temperature range, from the -25°C threshold up to the maximum operating limits of the engine.
Beyond the engine, the cooling system is another area where precision matters. The E350 requires 11.6 quarts of antifreeze. Our Passenger Car & Light Truck Antifreeze is a phosphate-free, nitrate-free, and borate-free solution that protects against corrosion without harming gaskets or hoses. For those who prefer a concentrated fluid that requires mixing with distilled water, the Propylene Glycol Antifreeze offers up to 150,000 miles of protection in passenger cars and extends even further in heavy-duty applications.
Transmission health is equally vital. While the vehicle does not list specific transmission filter changes, the fluid itself undergoes constant shear and thermal stress. The Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to resist oxidation and maintain its viscosity, which is crucial for the precision shift control required by the vehicle’s transmission. The OE Fuel-Efficient option provides a slightly more economical choice without sacrificing the wear protection necessary for daily driving.
Brake safety cannot be compromised. Mercedes-Benz typically specifies fluids that meet specific sheet standards, and our DOT 3 and DOT 4 100% Synthetic Brake Fluid is approved for use. It resists moisture absorption better than standard glycol-based fluids, preventing a drop in boiling point that can lead to brake fade under heavy use. This ensures consistent pedal feel and reliable stopping power in all weather conditions.
About the 2023 Mercedes-Benz E350
The 2023 Mercedes-Benz E350 represents a significant point in the evolution of the E-Class lineup. As a luxury sedan, the E-Class has long been a benchmark for the segment, balancing executive comfort with dynamic handling. The 2023 model year continues the legacy of the W213 platform, which introduced a refined interior design and advanced driver-assistance systems to the mainstream luxury market.
This specific E350 model is powered by the M264 engine, a 2.0-liter inline-four turbocharger. This engine family replaces the previous generation four-cylinder units and is known for its high specific output and efficiency. Despite being a four-cylinder, the 2.0L turbo provides robust acceleration that rivals larger engines, making it a favorite for city driving and highway cruising alike. The compact yet powerful nature of this engine means it operates at higher temperatures and pressures, making the high-performance lubricants recommended for this vehicle even more essential.
Owners of the E350 appreciate its blend of technology and comfort. The vehicle typically comes equipped with the MBUX infotainment system, which offers a seamless interface for navigation, media, and vehicle settings. The interior design philosophy focuses on a “sensual purity” aesthetic, utilizing high-quality materials and ergonomic seating that provide long-distance comfort. The car is engineered to handle a variety of road surfaces with a suspension that can be tuned for a balance of sportiness and ride comfort, depending on the driving mode selected.
In the context of maintenance, the E350’s electronic systems monitor engine performance closely, but they cannot compensate for the degradation of fluids over time. Using premium synthetic fluids ensures that the vehicle’s sensors and actuators function as intended, supporting the advanced drivetrain components. Whether for daily commuting or weekend drives, the E350 relies on the integrity of its lubricants to deliver the smooth, quiet operation and responsive performance that define the Mercedes-Benz brand. Proper care of these systems extends the vehicle’s life and maintains its value, ensuring that the driving experience remains pristine year after year.
Additional Maintenance Products
While the primary fluids are essential, supplementary products can further enhance the performance and protection of your vehicle. For seasonal storage, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog injectors. If the vehicle will be sitting for extended periods, Engine Fogging Oil provides a protective coating on internal components to prevent rust and corrosion.
For those who want to maximize fuel economy and power, AMSOIL P.i. Performance Improver Gasoline Additive is a potent choice. It has been shown to restore fuel injectors to 100% flow rate, improving horsepower and reducing the need for higher-octane fuel. The Upper Cylinder Lubricant further aids in this by lubricating the fuel system and cylinders, reducing friction and wear on upper engine parts.
Mechanical protection extends to the chassis and body as well. AMSOIL Synthetic Multi-Purpose Grease offers superior resistance to thermal degradation and shear, making it ideal for wheel bearings and other chassis points. For undercoating or protecting metal surfaces from salt and moisture, the Heavy-Duty Metal Protector provides a long-lasting, wax-like coating that seals out corrosion. For cleaning, the Engine Degreaser removes heavy grime from the engine bay, while the Brake and Parts Cleaner ensures that rotors and calipers are free of oil and residue before service.
Finally, keeping the exterior of the E350 looking pristine is important for a luxury vehicle. AMSOIL High-Foam Car Shampoo cleans effectively without stripping wax, while the Exterior Ceramic Spray offers rapid water shedding and UV protection. For interior surfaces, the Light Lemon Detailer or Scent-Free Detailer provide 90-day UV protection and trap odors, keeping the cabin fresh and protected from the sun’s damaging rays. By utilizing this complete range of products, E350 owners can ensure their vehicle receives comprehensive care from the engine block to the bumpers.
