The 2016 Mercedes-Benz GLC300 represents a significant step forward for the brand, combining the agility of a crossover with the refined performance of a luxury sedan. Powered by a turbocharged 2.0L four-cylinder engine, this vehicle demands lubricants that can handle high thermal loads, rapid acceleration, and the specific material tolerances of European engineering. Selecting the right fluids is not just about following a maintenance schedule; it is about ensuring long-term reliability and preserving the driving dynamics that owners value.
Recommended AMSOIL Products
Choosing the correct lubricant for the GLC300’s 2.0L engine (Code 274.920 A Turbo) is critical, as the manufacturer specifies precise viscosity grades and synthetic formulations to protect against turbocharger wear and sludge buildup. Below are the top-rated AMSOIL products tailored to the specific capacities and material requirements of this vehicle.
- AMSOIL 0W-40 FS 100% Synthetic European Motor Oil – Engineered for gasoline, diesel, and hybrid European vehicles, this premium synthetic oil features a precise blend of base oils and additives designed to protect tight-tolerance engines and turbochargers in all temperature ranges.
- AMSOIL 5W-40 FS 100% Synthetic European Motor Oil – An excellent choice for operation in temperatures above -25°C, this oil provides outstanding protection against high-temperature shear, ensuring the 2.0L turbo engine remains clean and efficient during extended service intervals.
- AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid – With superior resistance to moisture absorption and a stable viscosity over a wide temperature range, this fluid ensures consistent pedal feel and ABS responsiveness, meeting or exceeding Mercedes-Benz requirements.
- AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid – This fluid withstands the rigors of heavy towing, elevated transmission temperatures, and challenging terrain while maintaining fluidity in sub-zero conditions, protecting vital transmission components from wear.
- AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid – A high-performance alternative that offers excellent protection against wear and sludge, helping to extend transmission life while maintaining fuel economy.
- AMSOIL Passenger Car & Light Truck Antifreeze & Coolant – This 50/50 pre-mixed ethylene glycol formulation provides protection up to 150,000 miles or five years, featuring a poly-organic acid technology that is free of phosphates and silicates to protect all cooling system metals and hoses.
- AMSOIL Propylene Glycol Antifreeze and Engine Coolant – For owners requiring a concentrated solution, this product offers extended service life up to 1,000,000 miles or eight years in heavy-duty applications and greatly surpasses standards for metallic corrosion and erosion.
Maintaining your vehicle involves more than just oil changes. The cooling system, which requires approximately 9.5 quarts of fluid, is a critical component that ensures the turbocharged engine operates within safe thermal limits. Using an antifreeze formulated to exceed OEM requirements prevents corrosion and erosion, keeping the cooling system clean and efficient. Similarly, the braking system relies on a fluid that resists boiling and maintains viscosity; AMSOIL DOT 3 and DOT 4 brake fluid provides the stability needed for safe stopping power in any condition.
Essential Transmission and Transfer Case Care
The automatic transmission in the 2016 GLC300 requires a fluid capable of handling complex shifting patterns and high torque loads. Standard fluids can break down under severe driving conditions, leading to wear and reduced efficiency. AMSOIL’s fuel-efficient transmission fluids are designed to remain stable and fluid, protecting gears and bearings from damage. Additionally, for those with 4MATIC all-wheel-drive systems, the transfer case requires specific attention. While specific fill capacities can vary, ensuring the transfer case lubricant is suitable for the vehicle’s operating conditions is vital for smooth power distribution to all wheels.
Seasonal Protection and Fuel System Maintenance
For owners who store their vehicle seasonally or frequently drive in extreme cold, additional protection is available. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup in the fuel injectors and intake valves. Engine fogging oil is another valuable tool for winter storage, providing a protective layer on internal engine components to prevent rust and corrosion during long periods of inactivity. Furthermore, AMSOIL P.i.® Performance Improver Gasoline Additive can be used to clean fuel injectors, potentially restoring horsepower and improving fuel economy by clearing up carbon deposits that may have accumulated over time.
Vehicle Cleaning and Exterior Protection
Maintaining the appearance of your GLC300 is just as important as mechanical maintenance. With a combination of modern paints and protective coatings, regular washing with a high-foam car shampoo can effectively remove road grime without harming the finish. For those looking to extend the time between washes, AMSOIL Miracle Wash® offers a waterless wash and wax spray that leaves a fantastic shine and protective layer. To guard against harsh elements, an exterior ceramic spray can be applied to shed water rapidly and protect against UV rays, keeping the paint looking new for longer.
About the Vehicle
The 2016 Mercedes-Benz GLC300 marked the brand’s entry into the compact luxury SUV segment, filling a gap between the GLA and the larger GLE classes. Built on the MRA (Modular Rear Architecture) platform, which it shares with the W205 C-Class sedan, the GLC300 delivers a driving experience that prioritizes on-road agility and handling precision. It is powered by the M274 turbocharged 2.0L four-cylinder engine, which provides a robust balance of acceleration and fuel efficiency, characteristic of Mercedes-Benz’s downsizing strategy during this era.
This model was designed to appeal to urban drivers and families who value the comfort and safety features synonymous with the Mercedes-Benz badge but desire a more compact footprint than traditional full-size SUVs. The interior reflects the luxury standards of the brand, featuring high-quality materials, intuitive technology, and a focus on ergonomics. The GLC300’s reputation is built on its refined ride quality, where the suspension strikes a delicate balance between absorbing road imperfections and maintaining sporty responsiveness. Owners often appreciate the vehicle’s versatility, noting that the available 4MATIC all-wheel-drive system adds confidence in various weather conditions without compromising the car’s nimble character. Whether used for daily commuting or weekend excursions, the GLC300 offers a sophisticated blend of performance and practicality.
