The 2018 Mercedes-Benz GLA45 AMG is a high-performance compact SUV that packs a potent 2.0-liter turbocharged four-cylinder engine. This powerplant delivers impressive acceleration and dynamic handling, but it also places significant thermal and mechanical stress on the engine components. To ensure the longevity and peak performance of this sophisticated vehicle, using the correct lubricants is non-negotiable. Standard consumer-grade oils often break down under the extreme heat generated by a turbocharger, leading to sludge buildup and accelerated wear. AMSOIL synthetic lubricants are engineered to withstand these rigorous conditions, providing superior protection against wear, deposits, and oxidation, ensuring your GLA45 AMG remains responsive and reliable for years to come.

When selecting motor oil for the 2.0-liter 4-cylinder engine found in the GLA45 AMG, the specific requirements of the turbocharger system must be considered. The oil must maintain its viscosity under high heat to prevent thinning, which can lead to metal-to-metal contact. The engine capacity is listed at 5.8 quarts when changing with the oil filter. It is crucial to refill the engine and then check the oil level to ensure the correct amount is present. The oil drain plug requires a torque of 30 ft/lbs to prevent leaks or damage. AMSOIL offers two primary viscosity options that meet the stringent requirements for this European performance vehicle: 5W-40 and 0W-40. The 0W-40 option is particularly beneficial for cold starts, while the 5W-40 provides robust protection in a wide range of temperatures.
Beyond the engine, the cooling system plays a vital role in managing the heat generated by the AMG’s high-revving engine. The cooling system capacities vary depending on the specific configuration, with LTCC requiring 3.7 quarts and HTCC requiring 7.9 quarts. Maintaining the correct antifreeze & coolant mixture is essential to prevent overheating, freezing, and internal corrosion. AMSOIL’s antifreeze options, available in both pre-mixed and concentrated forms, utilize unique poly-organic acid technology. This formulation ensures compatibility with various metals and rubber components, protecting against the corrosive effects of old coolants that may have accumulated phosphates, nitrites, and silicates which can harm engine gaskets and seals over time.
Brake fluid is another critical fluid often overlooked until performance issues arise. The 2018 GLA45 AMG requires a DOT 4 Plus fluid to maintain the high-performance braking characteristics expected from an AMG model. The standard fluid must be resistant to boiling to ensure consistent pedal feel during aggressive driving. AMSOIL’s 100% synthetic brake fluid meets the necessary specifications, including MB Sheet 331.0, ensuring that the brake system remains responsive and safe. It provides a stable viscosity across a broad temperature range, which is essential for preventing vapor lock and maintaining hydraulic efficiency in the ABS and traction control systems.
About the Vehicle
The 2018 Mercedes-Benz GLA45 AMG represents the pinnacle of the compact luxury SUV segment. As part of Mercedes’ high-performance AMG division, this vehicle distinguishes itself from standard luxury crossovers with its focus on driving dynamics and speed. It rides on a platform shared with the A-Class, offering a blend of practicality and sporty handling that is rarely found in vehicles of this size. Under the hood lies the M133 engine, a 2.0-liter inline-four turbocharged powerplant that produces significant horsepower, allowing the GLA45 to compete with dedicated sports cars in terms of acceleration.
Owners of this vehicle typically appreciate its versatility. It serves as an excellent daily driver capable of handling urban commuting, family duties, and weekend adventures without sacrificing performance. The interior design reflects the premium nature of the brand, featuring high-quality materials, advanced infotainment systems, and supportive seating designed to hold passengers in place during spirited driving. The exterior styling is aggressive, characterized by a bold grille, flared wheel arches, and distinctive aerodynamic elements that signal its performance pedigree. This combination of a compact footprint and potent engine makes it a favorite among enthusiasts who value both efficiency and adrenaline.
Despite its robust engineering, the GLA45 AMG, like many modern turbocharged performance vehicles, can face specific maintenance challenges. One common issue involves carbon buildup on the intake valves and turbocharger, a result of direct fuel injection and high-temperature operation. The intense heat can cause oil to coke on the turbocharger bearings, leading to noise or premature wear. Using high-temperature resistant synthetic oils like AMSOIL FS helps mitigate this by providing better thermal stability and cleaner operation. Another potential concern is the degradation of the transmission fluid under severe driving conditions. The rapid acceleration and high RPMs can generate excessive heat, potentially causing the fluid to break down and lose its lubricating properties. Regular fluid changes with high-performance synthetic fluid can extend transmission life. Additionally, turbocharged engines are prone to sludge formation if oil change intervals are extended too far or if non-synthetic oils are used. The sludge can clog oil passages and starve critical components, leading to costly repairs. Finally, brake fade can be a concern during track days or aggressive street driving if the brake fluid absorbs moisture or boils. Upgrading to a synthetic brake fluid raises the boiling point, ensuring consistent braking performance when the vehicle is pushed to its limits.
Maintaining the GLA45 AMG with high-quality fluids is an investment in the vehicle’s future. The extreme conditions this SUV is designed to handle require lubricants that exceed standard industry specifications. By utilizing AMSOIL products, owners can ensure that their vehicle receives the protection it needs to perform at its best, regardless of the driving conditions. Whether commuting through city traffic or tackling a winding back road, the right lubricants provide the peace of mind that comes with knowing the vehicle is protected against wear, corrosion, and thermal breakdown.
