The 2022 Mercedes-Benz CLA45 AMG is a high-performance compact sedan that pushes the 2.0-liter turbocharged four-cylinder engine to its limits. Owners of this vehicle know that proper lubrication is not just a maintenance chore; it is a requirement for sustaining the vehicle’s power, protecting its sophisticated engine internals, and ensuring longevity. Because this engine is tuned for high output and operates at elevated temperatures, standard mineral oils will not provide adequate protection. Using a lubricant specifically engineered for European performance standards is essential to prevent wear, reduce thermal degradation, and maintain optimal fuel economy.
Recommended AMSOIL Products
For the 2022 Mercedes-Benz CLA45 AMG with the 2.0L 4-cylinder (Engine Code 139.980 1 Turbo), AMSOIL provides a comprehensive suite of synthetic lubricants designed to exceed original equipment manufacturer specifications. The following products are the top recommendations for maintaining this high-performance machine.
- AMSOIL 0W-20 LS 100% Synthetic European Motor Oil – Specifically formulated for the unique demands of modern European vehicles, this oil offers superior protection against high-temperature breakdown and deposits, with a capacity of 6.1 quarts including the filter.
- AMSOIL Passenger Car & Light Truck Antifreeze & Coolant – A phosphate-, nitrate-, and silicate-free ethylene glycol pre-mix that provides extended protection up to 150,000 miles or 5 years, perfect for the CLA45’s cooling system requirements.
- AMSOIL Propylene Glycol Antifreeze and Engine Coolant – A concentrated antifreeze option that requires mixing, offering exceptional corrosion protection and thermal stability for long-life service intervals.
- AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid – Designed to meet the strict requirements of Mercedes-Benz (MB Sheet 331.0), this fluid ensures consistent pedal feel and stability under the extreme heat generated by the AMG braking system.
Using the correct oil grade is the first step in protecting your investment. The 2022 CLA45 AMG requires a 0W-20 viscosity to ensure proper flow during cold starts and sufficient film strength at operating temperatures. When performing an oil change, the system requires 6.1 quarts when a filter is replaced. It is crucial to follow the manufacturer’s torque specifications, specifically applying 22 ft/lbs to the oil drain plug, and always replace the drain plug seal to prevent leaks.
Beyond the engine, the cooling system of the CLA45 AMG plays a critical role in performance. The system utilizes a specific volume of coolant, with the Long Term Coolant Capacity (LTCC) requiring 2.7 quarts and the High Temp Coolant Capacity (HTCC) requiring 12.3 quarts depending on the configuration. Maintaining the cooling system with a high-quality antifreeze is vital to prevent overheating, which can be detrimental to a turbocharged engine. AMSOIL’s OAT formulations provide robust protection for all cooling system metals, gaskets, and hoses, ensuring that the engine temperature remains regulated even during aggressive driving on the track or spirited highway runs.
Braking performance is another area where synthetic fluids offer a distinct advantage. The CLA45 AMG is equipped with a powerful braking system that must respond instantly. AMSOIL DOT 3 and DOT 4 Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems. It maintains a stable viscosity across a wide temperature range, preventing the fluid from boiling under hard braking conditions. This stability is essential for maintaining safety and control when pushing the vehicle to its limits.
Model History and Performance
The Mercedes-Benz CLA Class represents the brand’s entry into the compact luxury segment, specifically designed to blend sporty aesthetics with everyday usability. The CLA45 AMG, introduced as the high-performance variant, brings the legendary AMG division’s expertise to this compact footprint. Based on the Mercedes-Benz A-Class platform, the CLA45 AMG is widely regarded as a “hot hatch” sedan, offering the agility of a sports car in a four-door body. The model is powered by the M139 engine, a 2.0-liter inline-four turbocharger that has gained a reputation as one of the most powerful four-cylinder engines in automotive history.
When the 2022 model year arrived, owners were looking at a vehicle that could rival sports cars costing significantly more. The 2022 CLA45 AMG typically produces around 416 horsepower, a figure that has been refined over previous generations to offer a broader torque curve. The driving character is sharp, with an instantaneous throttle response and a gearbox that shifts faster than many manual transmissions. The all-wheel-drive system, known as AMG Performance 4MATIC, sends power to the rear wheels primarily but can distribute torque to the front as needed, providing incredible traction in all weather conditions while maintaining the rear-wheel-drive bias that enthusiasts prefer.
Despite its compact size, the CLA45 AMG has carved out a niche among driving enthusiasts who appreciate German engineering. The interior combines luxury materials with sport seats designed for high G-forces, while the exterior features distinctive AMG styling cues like a prominent grille and large alloy wheels. The vehicle is known for its ability to be a daily driver that is equally comfortable in traffic as it is on a winding road. However, the high stress placed on the engine and drivetrain means that owners must prioritize premium fluids to maintain reliability.
There are common issues that can arise with this high-strung engine if proper maintenance is neglected. One frequent concern is carbon buildup on the intake valves, a problem common to many Direct Injection (GDI) engines, which can lead to reduced power and rough idling. Using a fuel additive like AMSOIL P.i.® Performance Improver can help clean these injectors and restore horsepower. Another issue is the potential for oil sludge in the turbocharger bearings if synthetic oil with high shear stability is not used, as the turbo spins at extremely high RPMs. The correct AMSOIL European Motor Oil is formulated to resist this shear degradation. Owners also report issues with coolant degradation in older models, which can lead to overheating; flushing the system with a high-quality antifreeze like AMSOIL Antifreeze & Coolant can prevent this. Finally, brake fade under extreme use can occur if the brake fluid absorbs moisture over time, a condition that synthetic brake fluid helps to mitigate by having a higher boiling point.
In summary, the 2022 Mercedes-Benz CLA45 AMG is a technological marvel that rewards owners who treat it with the care it deserves. By utilizing the recommended AMSOIL synthetic lubricants, owners can ensure that their vehicle continues to deliver the thrilling performance and reliability that the AMG badge promises. Whether tackling the daily commute or enjoying a weekend drive on back roads, the right fluids make a noticeable difference in the vehicle’s operation.
