For the 2018 Lincoln MKZ 2.0L engine, AMSOIL recommends using 0W-20 viscosity motor oil across all temperature ranges. The engine oil capacity is 4.5 quarts when the filter is replaced, and it is essential to check the oil level after refilling to ensure the correct amount has been added. When performing an oil change, the oil drain plug should be torqued to 20 ft-lbs to ensure a proper seal without risking damage to the thread. The engine operates with a turbocharger, making oil quality crucial for bearing lubrication and cooling under high-load conditions.
AMSOIL Signature Series 0W-20 is the top choice for this vehicle, as it has been tested to provide 75% more engine protection against horsepower loss and wear compared to industry standards. It also offers a guaranteed protection period of up to 25,000 miles or one year, whichever comes first. This extended interval capability is made possible by the oil’s superior resistance to thermal breakdown and oxidation, ensuring that the oil maintains its protective properties throughout the service life. For those seeking a balance between cost and performance, the AMSOIL OE 0W-20 provides robust protection that outperforms conventional oils and meets the specific requirements of the engine’s turbocharger.
High-mileage vehicles that have surpassed 75,000 miles benefit significantly from AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil. This formulation includes a boosted detergent package to clean sludge and deposits, along with enhanced anti-wear additives that help preserve engine performance. The unique chemistry of this oil reduces sludge by 67% and improves cleaning power, which is particularly beneficial for older engines where carbon buildup can affect fuel economy and power output.
Transmission and Cooling System Care
Protecting the transmission is just as vital as maintaining the engine. The 2018 Lincoln MKZ utilizes an automatic transmission that benefits from AMSOIL’s fuel-efficient synthetic fluid. For total fill applications, approximately 4.8 quarts are required for the HF35 fluid type. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and high operating temperatures. It remains fluid even in sub-zero temperatures, ensuring smooth shifting and reliable operation regardless of the season.
The cooling system of the MKZ must be capable of dissipating heat generated by the turbocharged engine effectively. AMSOIL offers two primary coolant options for this application. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 ethylene glycol formulation that provides up to 150,000 miles or 5 years of protection. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it compatible with all cooling system metals, gaskets, and hoses. For those who prefer a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended life and meets or exceeds all original equipment manufacturer requirements for corrosion and erosion protection.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid maintenance is another critical aspect of vehicle safety. It provides a stable viscosity across a wide temperature range, which ensures consistent brake pedal feel and responsiveness. This synthetic fluid also enhances the performance of ABS and traction control systems, offering a safety margin that conventional brake fluids may not match.
About the Vehicle
The 2018 Lincoln MKZ represents the pinnacle of the brand’s luxury sedan lineup, offering a blend of comfort, style, and technology that appealed to a discerning demographic. Built on the same versatile Ford Fusion platform as its Ford counterpart, the MKZ distinguishes itself with premium interior materials, a quiet cabin, and a sophisticated driving experience. The 2.0L EcoBoost engine, with its turbocharging technology, delivers a responsive power curve that makes this sedan feel surprisingly agile for its size. This engine choice was popular among buyers who wanted the efficiency of a four-cylinder without sacrificing the power needed for highway merging or passing maneuvers.
Ownership of the MKZ is often associated with a premium driving character. The suspension is tuned to absorb road imperfections smoothly, providing a “gliding” sensation that is characteristic of Lincoln vehicles. The interior is spacious, with a focus on ergonomic design and high-quality finishes that set it apart from standard mid-size sedans. For many owners, the MKZ serves as a daily driver that doubles as a comfortable long-distance cruiser, capable of carrying passengers and luggage with ease. The availability of the hybrid variant during this model year also highlighted the brand’s commitment to efficiency, but the 2.0L turbo remains a strong performer for those who prioritize driving dynamics.
Despite its refined engineering, like many modern turbocharged vehicles, the 2018 Lincoln MKZ is not without its specific maintenance needs. Owners should be aware of potential issues related to carbon buildup in the intake valves, a common characteristic of direct injection engines. Over time, carbon deposits can restrict airflow and reduce engine efficiency. Regular use of a high-quality fuel system cleaner like AMSOIL P.i. can help mitigate this issue, keeping injectors clean and maintaining optimal airflow.
Another common concern for high-mileage MKZ owners is oil consumption. While the engine is generally reliable, some units may begin to consume more oil than expected as they age, particularly if exposed to harsh driving conditions or frequent short trips. Switching to AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil can address this by sealing aging engine components and reducing oil burn-off. This change can extend the intervals between oil top-offs and ensure the engine maintains its compression and power output.
Transmission shudder or delayed shifting can occasionally occur in this model, often linked to the accumulation of varnish and sludge in the transmission system. Using a synthetic transmission fluid like the AMSOIL Signature Series can prevent this buildup and ensure smooth gear changes, extending the life of the transmission components. Additionally, the brake system requires regular fluid flushes to prevent moisture absorption, which can lower the fluid’s boiling point and lead to brake fade. AMSOIL Synthetic Brake Fluid resists this absorption, ensuring consistent braking performance and protecting the hydraulic components from corrosion.
Ultimately, the 2018 Lincoln MKZ is a vehicle that rewards careful maintenance. By using the correct AMSOIL lubricants, owners can maximize the vehicle’s potential, ensuring it remains a reliable and comfortable companion on the road. Whether it is for daily commuting or weekend adventures, proper fluid selection is the key to unlocking the full capabilities of this luxury sedan.
