The lubrication requirements for the 2016 Lincoln MKS 3.5L EcoBoost are specific and demanding. The engine utilizes a 5W-30 viscosity grade across all temperatures. The system holds a total capacity of 6.0 quarts, including the filter replacement. After refilling, it is crucial to check the oil level to ensure the proper amount has been added. The oil drain plug torque specification is 20 ft/lbs, a detail that prevents damage to the oil pan threads during service. Choosing the right filter is just as important as the oil itself. The AMSOIL EAO17 filter or the WIX 57502 series are recommended to ensure contaminants are trapped effectively without restricting flow, which is vital for maintaining oil pressure in a turbocharged engine.
While the engine oil receives the most attention, the cooling system plays a pivotal role in the longevity of the MKS. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity is substantial, requiring 11.4 quarts to fill the system completely. A high-performance AMSOIL Propylene Glycol Antifreeze and Engine Coolant ensures protection against corrosion and cavitation. These formulations are free of phosphates, nitrates, and silicates, making them safe for all metals in the cooling system. They are designed to last up to 150,000 miles or five years, matching the long service intervals possible with synthetic motor oils. Neglecting the cooling fluid can lead to overheating, which is particularly dangerous for a high-output turbocharged engine.
Transmission health is another critical component of the MKS maintenance schedule. The 2016 model features a 6-speed automatic transmission (6F55). A total fill requires 11.6 quarts of fluid. For this transmission, AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid are ideal. Both are designed to withstand the heat and shear stress generated during operation, particularly if the vehicle is used for towing or driving in mountainous terrain. These synthetic fluids remain stable in extreme temperatures, ensuring smooth shifting and protecting internal components from sludge and varnish buildup. Regular fluid exchanges are recommended to maintain optimal performance, especially if the vehicle is subjected to severe driving conditions.
Differential and transfer case lubrication often goes overlooked, yet it is essential for all-wheel-drive systems like the MKS’s. The Power Transfer Unit (PTU) requires SAE 75W-140 synthetic rear axle lubricant, with a capacity of 1.1 pints. AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube is the ideal specification, offering protection against thermal runaway which can occur in the PTU. The rear differential, on the other hand, requires SAE 80W-90 lubricant that meets Ford specification WSP-M2C197-A, with a capacity of 2.4 pints. AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube provides this protection, containing friction modifiers suitable for limited-slip applications and reducing operating temperatures to extend the life of the gears and bearings.
About the 2016 Lincoln MKS
The 2016 Lincoln MKS represents a pinnacle of American luxury sedan engineering. As the luxury counterpart to the Ford Taurus, the MKS was built on the D4 platform, designed from the ground up to blend sophisticated styling with high-performance capabilities. The vehicle is characterized by its sleek, elongated profile and a spacious, quiet interior that prioritizes rider comfort above all else. By 2016, the MKS had fully embraced the 3.5L EcoBoost V6 engine option, a twin-turbocharged powerhouse that delivered performance levels previously unheard of in this class of vehicle.
Owners of this era’s MKS appreciate its balance of refinement and power. The 3.5L V6, often referred to as the EcoBoost, produces substantial horsepower and torque, allowing the heavy sedan to accelerate with surprising urgency despite its weight. This engine choice transformed the MKS from a purely cruiser-class sedan into a genuine performance machine without sacrificing the plush ride quality that the Lincoln brand is famous for. The interior features high-quality materials, ample rear legroom, and advanced technology that was cutting-edge for its time, making it a favorite for those who needed a vehicle for both business and leisure.
The vehicle’s all-wheel-drive system, paired with the powerful turbo engine, ensures confidence in adverse weather conditions, a significant factor in Lincoln’s market positioning against German competitors. The MKS was positioned as a full-size luxury sedan that offered a unique American alternative to the European dominance in the luxury segment. While production of the MKS eventually ceased to make way for the Nautilus crossover and the Lincoln Aviator, the 2016 model year stands as a testament to the platform’s durability and the success of the EcoBoost technology. Maintaining this vehicle with premium fluids ensures that its legacy of performance and luxury remains intact for years to come.
Why Proper Lubrication Matters for Your MKS
The specific engineering of the 3.5L EcoBoost engine makes the choice of motor oil a decision that directly impacts vehicle performance and durability. Turbochargers spin at extremely high speeds and operate in high-heat environments, necessitating oil that can resist thermal breakdown and provide a stable film of lubrication. AMSOIL Signature Series 5W-30, with its advanced synthetic base stock, excels in these conditions, providing 75% more protection against horsepower loss and wear compared to conventional oils. This ensures that the turbocharger bearings remain healthy and the engine retains its compression and efficiency over the long term.
Furthermore, the synthetic formulation of these oils helps manage the unique challenges of modern fuel systems. The MKS is equipped with Direct Injection (GDI), which can lead to pre-ignition events known as Low-Speed Pre-Ignition (LSPI). AMSOIL OE and Signature Series oils are formulated to fight LSPI, preventing potential catastrophic engine damage. The high detergent content in these oils also keeps the internal components clean, reducing the buildup of carbon deposits on valves and pistons. This level of cleanliness is not just about maintaining appearance; it is about ensuring the engine breathes properly and runs efficiently.
For owners of older MKS units, or those looking to maximize the life of their vehicle, the AMSOIL High-Mileage 5W-30 offers specific benefits. Vehicles with over 75,000 miles may experience increased oil consumption or minor seal leaks. The unique chemistry in the High-Mileage formula includes boosted detergents, enhanced anti-wear additives, and seal conditioners that help reduce sludge and minor leaks. This allows the engine to run cleaner and smoother, extending the service life of a vehicle that has already seen significant mileage.
Seasonal and Storage Considerations
While daily maintenance keeps the Lincoln MKS running, proper preparation for seasonal changes or long-term storage is equally important. If the vehicle is to be stored for an extended period, using AMSOIL P.i.® Performance Improver before the storage period begins can help clear out any carbon buildup. For the storage phase itself, AMSOIL Engine Fogging Oil can be added to the cylinders to prevent rust and corrosion on internal components. Additionally, AMSOIL Gasoline Stabilizer can be added to the fuel tank to keep the fuel fresh for up to 12 months, protecting against varnish and gum buildup that can clog fuel injectors.
Cleaning and protecting the exterior is also part of a comprehensive maintenance routine. Products like the AMSOIL Miracle Wash Waterless Wash and Wax Spray allow for safe cleaning without harsh detergents, while the AMSOIL Exterior Ceramic Spray provides a durable, water-shedding layer of protection against UV rays and environmental contaminants. For those who operate their MKS in harsh winter conditions, the AMSOIL Silicone Spray can be used to protect rubber components and locks from freezing, ensuring that all moving parts remain functional regardless of the weather outside.
In summary, the 2016 Lincoln MKS 3.5L is a sophisticated vehicle that demands high-quality fluids to perform as intended. From the engine oil and filter to the transmission fluid, gear lubes, and coolants, every component plays a vital role in the vehicle’s reliability. By selecting the recommended AMSOIL products, owners can ensure that their luxury sedan continues to deliver the performance, safety, and comfort that define the Lincoln brand. Whether you are an enthusiast who drives hard or a daily commuter looking for peace of mind, the right lubricants are the foundation of a well-maintained vehicle.
