The 2023 Mercedes-Benz CLA35 AMG is a high-performance luxury vehicle that demands the very best in maintenance to ensure longevity and peak performance. At the heart of this machine lies the 2.0L turbocharged 4-cylinder engine, known as the M260, which produces significant power while operating under extreme thermal and mechanical stress. Using the correct lubricants is not just a recommendation; it is a requirement for this sophisticated German engineering. The factory-recommended oil specifications for this engine allow for specific viscosities like 0W-20, 0W-30, and 0W-40 depending on the temperature, with 5W-30 and 5W-40 also being suitable for conditions above -25°C. To match these demanding requirements, owners need a lubricant capable of resisting breakdown, managing heat, and protecting critical components like the turbocharger and the engine’s tight tolerances.

When performing an oil change on the 2023 CLA35 AMG, precision is key. The engine requires 5.8 quarts of oil when the filter is replaced. It is crucial to refill the system carefully and then check the oil level to ensure the correct quantity is in place. The oil drain plug must be torqued to exactly 30 ft/lbs to prevent leaks or damage to the drain plug hole. Furthermore, replacing the drain plug seal with every oil change is a best practice to maintain a perfect seal. While the vehicle summary indicates no specific AMSOIL filter recommendation is available for this model, using a high-efficiency oil filtration system remains vital for capturing contaminants and protecting the turbocharger bearings. For general maintenance tasks, AMSOIL Synthetic Multi-Purpose Grease can be used for chassis points requiring lubrication.
Cooling and Brake Systems
The cooling system for this vehicle holds approximately 9.4 quarts of fluid. Maintaining the integrity of the cooling system is essential for the turbocharged engine, which runs at higher temperatures than naturally aspirated units. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant offers long-lasting protection, with the pre-mixed formula providing protection up to 150,000 miles or five years. The concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant is also an excellent choice for those who prefer to mix their own coolant. Both formulations are free of phosphates, nitrates, nitrites, silicates, borates, and amines, ensuring compatibility with the engine’s cooling materials.
Brake safety cannot be overlooked. The manufacturer recommends using DOT 4 plus or products approved on MB Sheet 331.0. AMSOIL’s 100% Synthetic Brake Fluid meets these high standards, ensuring consistent pedal feel and preventing fluid boil during spirited driving. It is designed to provide stable viscosity, which is critical for maintaining the performance of the vehicle’s advanced braking and traction control systems.
Additional Maintenance and Protection
For those who store their vehicles or drive in extreme conditions, adding AMSOIL P.i. Performance Improver can restore up to 14% horsepower and clean GDI fuel injectors. This gasoline additive helps improve fuel economy and reduces the need for higher-octane fuel. Additionally, AMSOIL Engine Fogging Oil is highly effective for protecting internal engine components during long periods of inactivity, such as winter storage. Using a fuel stabilizer like AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog injectors.
General Care and Cleaning
Maintaining the exterior and interior of the CLA35 AMG is part of a comprehensive care routine. For cleaning brake components, the AMSOIL Brake and Parts Cleaner quickly removes contaminants without leaving residue. Exterior care can be handled with the AMSOIL Miracle Wash Waterless Wash and Wax Spray, which repels dust and provides a protective finish, or the AMSOIL Exterior Ceramic Spray for rapid water shedding and UV protection. These products help keep the vehicle looking pristine while protecting its surfaces. For interior maintenance, the AMSOIL Interior Detailer – Light Lemon offers multi-surface cleaning with UV protection, or the AMSOIL Interior Detailer – Scent Free can be used for a neutral option. To clean glass surfaces, the AMSOIL Glass Cleaner provides a streak-free shine. For heavy grease on engine parts, the AMSOIL Engine Degreaser is a professional-strength solvent. To protect metal surfaces from rust and corrosion, AMSOIL Heavy-Duty Metal Protector or AMSOIL MP Metal Protector can be applied. Additionally, the AMSOIL Mudslinger® Mud and Dirt Repellent helps keep dirt and grime at bay. For rubber and plastic parts, the AMSOIL Silicone Spray provides a dry lubricating film. For general heavy grime, the AMSOIL Heavy-Duty Degreaser works fast. For carburetor and induction system cleaning, the AMSOIL Power Foam® is highly effective. For bucket washing, the AMSOIL High-Foam Car Shampoo is hard on dirt but gentle on finishes.
