Essential Engine Maintenance Specifications
The heart of your 2022 Lincoln Nautilus is the 2.0L EcoBoost four-cylinder engine, a sophisticated powerplant that relies on high-quality lubrication to operate efficiently. For the engine oil, the manufacturer specifies a 5W-30 viscosity grade for general use, with an oil capacity of 5.5 quarts when including the filter. This capacity is critical to ensure the engine is properly lubricated without overfilling, which could lead to pressure issues. The oil drain plug torque should be set to 20 ft/lbs to ensure a secure seal without damaging the threads. In extreme climates where ambient temperatures drop to -30°C (-22°F) or below, owners may opt for a 0W-30 oil meeting the WSS-M2C963-A1 specification to improve cold-start performance, though 5W-30 remains the primary recommendation for most driving conditions.
Why does this matter? Modern turbocharged engines run at significantly higher temperatures than naturally aspirated units. The turbocharger spins at incredibly high speeds and generates intense heat that can break down conventional oils quickly. AMSOIL synthetic motor oils are engineered to resist this thermal breakdown, maintaining their protective film even under the harshest conditions. This prevents sludge formation, reduces engine wear, and helps maintain the power output that drivers expect from the Lincoln brand.
Transmission and Drivetrain Care
Moving power from the engine to the wheels, the automatic transmission is another critical component requiring specific attention. The 2022 Nautilus utilizes an 8-speed automatic transmission, model 8F35. The total fill capacity for this transmission is 8.5 quarts, a volume that ensures the torque converter and gears are fully submerged in lubricant for proper cooling and operation. While the transmission fluid is often a lifetime fill in many contexts, using a dedicated synthetic automatic transmission fluid can provide significant benefits for longevity, especially if the vehicle is used for towing or driving in severe conditions.
The AMSOIL Signature Series ULV is formulated to meet the rigorous demands of these modern transmissions. It withstands heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero temperatures. This fluid provides reserve protection during heavy use and abuse, ensuring smooth shifting and reduced wear on transmission components. The fluid’s thermal stability helps prevent the oxidative breakdown that leads to sludge and varnish, which can clog valves and lead to costly repairs.
For the drivetrain, the transfer case and rear differential require specialized lubrication. The transfer case, identified as PTU, requires a full capacity of 0.8 pints of synthetic oil meeting GL-5 specifications. Similarly, the rear differential holds 1.8 pints. These components operate under heavy loads and are subject to high pressure and friction. AMSOIL SEVERE GEAR® 75W-85 offers advanced protection against wear and thermal runaway, which is the dangerous increase in temperature that can destroy gear oil. It also protects against rust and corrosion, helps reduce operating temperatures, and extends the life of oil seals and equipment. The inclusion of friction modifiers makes it ideal for limited-slip applications often found in these drivetrains.
Cooling System and Fluid Maintenance
A properly functioning cooling system is vital for a turbocharged engine, which generates substantial heat. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity for the 2022 Nautilus varies slightly depending on the specific configuration, with options for 10.4 quarts or 9.7 quarts when using the AHR10 system. Regardless of the exact volume, the quality of the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is paramount. AMSOIL offers two excellent options for this application. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that is safe for a wide variety of vehicles and engines. It protects cooling system metals, gaskets, and hoses and is compatible with all other antifreeze colors.
For those who prefer a concentrated formula that can be mixed with distilled or high-quality water to achieve the desired protection levels, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is an outstanding choice. This formulation offers protection up to 150,000 miles or 5 years in passenger cars and light trucks. It greatly surpasses standards for metallic corrosion and erosion and is free from phosphates, nitrates, nitrites, silicates, borates, and amines, making it safe for all engine metals and hoses.
Brake Fluid and Safety
Safety systems like brakes are critical for a vehicle of this size and performance capability. The recommended brake fluid for the Nautilus is a Motorcraft DOT 4 LV High Performance Brake Fluid or an equivalent meeting WSS-M6C65-A2 or ISO 4925 class 6. For superior performance, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent alternative. It provides excellent ABS and traction-control responsiveness and maintains a stable viscosity over a wide temperature range, ensuring consistent pedal feel and safe stopping power in any condition.
Fuel System and Additives
To keep the engine running at peak efficiency, maintaining a clean fuel system is essential, particularly for direct injection engines like the one in the Nautilus. Carbon buildup can significantly impact performance and fuel economy. The AMSOIL P.i. Performance Improver is a potent gasoline additive that restores up to 14% horsepower and cleans fuel injectors to 100% flow rate after just one tank of fuel. It helps prevent carbon rap and controls pre-ignition knock, which are critical for turbocharged engines. For seasonal storage, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup and ethanol corrosion.
