The heart of the 2022 Lincoln Navigator is its 3.5-liter EcoBoost V6 engine, a twin-turbocharged powerhouse that delivers immense torque but also generates significant heat. Selecting the correct viscosity is critical, and for this engine, a 5W-30 grade meeting the strict WSS-M2C963-A1 specification is required. In extreme cold climates where ambient temperatures drop to -22°F (-30°C) or below, AMSOIL recommends a 0W-30 oil to ensure immediate lubrication during cold starts. With a fluid capacity of 6.0 quarts including the filter change, the right oil volume is essential to maintain proper pressure and cooling. The AMSOIL Oil Filter (EAO17) is specifically designed to pair with these oils, utilizing a synthetic blend media that captures 99 percent of particles at 20 microns. This filtration efficiency keeps the critical turbocharger bearings clean and reduces the risk of coking, a common issue in high-heat turbo applications where conventional oils can degrade and leave deposits. For owners looking for a slightly more budget-friendly option that still delivers synthetic performance, the OE 5W-30 provides excellent protection for up to 15,000 miles, effectively fighting sludge and deposits without sacrificing cleanliness.
Moving beyond the engine, the cooling system of the Navigator requires attention to prevent overheating during heavy towing or stop-and-go traffic. The system holds a substantial 16 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Using a high-quality antifreeze is vital to protect aluminum components from corrosion and to prevent boil-over. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol-based, phosphate-free formula that exceeds OEM requirements and protects for up to five years or 150,000 miles. Alternatively, the concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a longer service life, extending up to 150,000 miles in passenger cars and light trucks, providing robust protection against metallic corrosion and erosion. This proactive approach to cooling system maintenance ensures the turbocharged engine stays within its optimal operating temperature range, preserving its performance and longevity.
The 2022 Navigator’s 10-speed automatic transmission (10R80) is a marvel of engineering designed to handle the vehicle’s weight and power, but it operates under high thermal loads. Proper fluid selection is key to preventing shift harshness and wear. For the most demanding driving conditions, including heavy towing, the AMSOIL Signature Series ULV 100% Synthetic Automatic Transmission Fluid is the premier choice. It remains fluid in sub-zero temperatures and provides a reserve of protection during abuse, ensuring smooth shifts under load. The capacity for a total fill of the 10-speed transmission is 13 quarts, which requires precision to avoid under- or over-filling. For those who prefer a fuel-efficient formulation, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid also deliver 100% synthetic protection against wear while optimizing for fuel economy. Maintaining the transmission fluid is as important as the oil, as the transmission is the most expensive component to replace if failure occurs due to degraded fluid.
Different and transfer cases also benefit from synthetic lubrication to ensure smooth power delivery to all four wheels. The front differential requires 3.6 pints, while the rear standard differential takes 5.1 pints, and the limited-slip rear differential needs 4.9 pints. For these applications, AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube is recommended. This fluid contains friction modifiers that are essential for limited-slip differentials to prevent wind-up and chattering while providing excellent wear protection. The synthetic formulation helps control thermal runaway, a condition where extreme heat causes the fluid to lose its protective properties, leading to gear failure. By using AMSOIL SEVERE GEAR, owners ensure their differentials operate smoothly and efficiently, regardless of whether they are hauling a boat or navigating slippery roads. The transfer case, while capacity varies by configuration, also benefits from the high thermal stability and shear resistance of this gear lube. Finally, the brake system requires a fluid that does not absorb moisture, which lowers the boiling point and compromises stopping power. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers superior resistance to moisture absorption and a high boiling point, ensuring crisp brake pedal feel and reliable ABS responsiveness, which is crucial for a vehicle of this size.

This model is designed for those who require maximum space and capability without compromising on comfort. The vehicle is known for its massive presence on the road, offering seating for up to eight passengers with a cabin that feels more like a first-class lounge than a standard transport vehicle. Owners often cite the ride quality as a standout feature, with the available air suspension system effectively isolating passengers from road imperfections, making it an ideal choice for long-distance travel.
Under the hood, the 3.5-liter twin-turbo V6 engine delivers a blend of power and efficiency that has made the EcoBoost family legendary. It produces over 400 horsepower, allowing this nearly 6,000-pound SUV to accelerate with surprising agility. This powertrain is capable of towing up to 8,700 pounds when properly equipped, making the Navigator a legitimate alternative to a tow truck for recreational vehicles, boats, and campers. However, this capability places a premium on the quality of fluids used. The stress of towing, combined with the high operating temperatures of the turbochargers, demands a lubrication regime that exceeds the minimum manufacturer requirements. The Navigator’s advanced technology, including its adaptive cruise control and lane-keeping systems, relies on the vehicle’s precise electronic and hydraulic systems, which are in turn dependent on the integrity of the fluids that power them.
While the Navigator is a marvel of modern engineering, no vehicle is without its challenges, particularly when subjected to the demanding use cases it was designed for. One of the most common concerns for owners of EcoBoost engines, including the one in the Navigator, is the issue of carbon buildup and turbocharger coking. High-temperature operation can cause oil to break down, leaving deposits on the turbo bearings and in the intake system. Using a high-quality synthetic oil with superior thermal stability, such as AMSOIL Signature Series, significantly mitigates this risk by resisting breakdown and keeping these critical components clean. This is a proactive measure that addresses a known failure point in high-mileage or heavy-duty usage scenarios.
A second common issue involves the cooling system, particularly when the vehicle is used for towing in hot climates. The massive cooling load required to keep the 3.5L engine and its turbos at bay can be taxing on the standard factory coolant, potentially leading to overheating or corrosion over time. Upgrading to a high-performance synthetic coolant with enhanced corrosion inhibitors and higher thermal capacity can prevent these issues, ensuring the engine runs at the optimal temperature even under heavy loads. This not only protects the engine but also helps maintain the efficiency of the air conditioning system, which is vital for a vehicle of this size.
Thirdly, the 10-speed automatic transmission can sometimes exhibit harsh shifts or fluid degradation when subjected to heavy towing or frequent stop-and-go traffic. Transmission fluid breakdown can lead to increased wear on the clutch packs and bands, potentially resulting in costly repairs. Regular fluid changes using a high-synthetic fluid like AMSOIL Signature Series ULV can prevent this degradation, ensuring that the transmission shifts smoothly and maintains its hydraulic integrity. The fluid’s ability to withstand shear forces and maintain viscosity under load is a key factor in extending the life of this complex gearbox.
Finally, differential wear is a concern for vehicles that are frequently used for towing or driving in slippery conditions. The limited-slip differentials can experience chattering and uneven wear if the fluid does not contain the correct friction modifiers or if the fluid breaks down under the high loads. Synthetic gear lubes designed for these specific applications provide the necessary film strength and friction modifiers to prevent these symptoms, ensuring smooth power delivery to all four wheels and extending the life of the differential components. By addressing these specific potential problem areas with the correct lubricants, owners can ensure their 2022 Lincoln Navigator remains a reliable and luxurious companion for years to come.
