Ensuring your 2022 Jeep Wagoneer with the 5.7L V8 engine receives the proper lubrication is essential for maintaining its performance, fuel economy, and longevity. This powerful truck-based SUV relies on specific viscosity grades and standards to operate correctly under varying driving conditions, from daily commuting to hauling heavy loads. Using the correct fluids not only protects critical internal components from wear but also helps prevent issues like sludge buildup and thermal degradation. The manufacturer specifies a 0W-20 viscosity that meets the MS-6395 standard, a requirement that AMSOIL Signature Series full synthetic oils are uniquely positioned to exceed.

Engine Oil Specifications and Service Intervals
The 2022 Jeep Wagoneer equipped with the 5.7L Hemi V8 is engineered to run on 0W-20 viscosity oil that meets the manufacturer’s MS-6395 material standard. While equivalent full synthetic oils with the API Starburst trademark are acceptable, AMSOIL products exceed these requirements to provide superior protection. The engine oil capacity for this vehicle, including the filter, is 7.0 quarts. After refilling the system, it is crucial to check the oil level to ensure the correct amount is present. The oil drain plug should be torqued to 25 ft/lbs to prevent leaks or stripping. Using a high-quality filter is just as important as the oil itself; the AMSOIL Oil Filter (EA15K50) or the WIX Oil Filter (57060) are both excellent choices to ensure contaminants are removed efficiently.
Drivers who put their Wagoneers through severe service, such as frequent towing, hauling, or extreme temperature fluctuations, will find the Signature Series or Extended-Life motor oils particularly beneficial. The Signature Series offers a guaranteed service interval of up to 25,000 miles or one year, significantly reducing the number of maintenance visits required over the vehicle’s life. For those driving high-mileage vehicles, the High-Mileage formulation contains unique chemistry with boosted detergents to clean sludge and anti-wear additives to help extend engine life.
Transmission and Differential Care
The automatic transmission in the 2022 Wagoneer uses the 8HP75 unit, which requires a specific fluid to handle its complex shifting logic and heavy-duty applications. The total fill capacity for this transmission is 9.5 quarts. AMSOIL Synthetic Automatic Transmission Fluids are engineered to withstand the rigors of heavy towing and elevated temperatures, ensuring smooth shifts and protecting against wear and sludge. The Signature Series ATF is recommended for drivers who demand maximum protection during abuse, while the OE Fuel-Efficient fluid offers a solid alternative that meets OEM standards while improving fuel economy.
For the rear differential, the vehicle utilizes a 230RIA unit that may or may not include an Electric Limited Slip Differential (ELSD). This component requires a 100% synthetic 75W-85 gear lube meeting GL-5 standards. If the unit is equipped with ELSD, a capacity of 2.7 pints is required; otherwise, 2.3 pints is needed. Using a synthetic gear lube like the SEVERE GEAR® 75W-85 provides advanced protection against wear, controls thermal runaway, and helps reduce operating temperatures. It also contains friction modifiers essential for the proper operation of limited-slip differentials.
Coolant and Brake Systems
Proper cooling system maintenance is vital for the longevity of the 5.7L engine. The system requires a total capacity of 16.9 quarts of AMSOIL Passenger Car & Light Truck Antifreeze. This phosphate-, nitrate-, and nitrite-free formulation protects all cooling system metals, gaskets, and hoses. It is an ethylene glycol-based pre-mix that offers protection for up to 150,000 miles or 5 years. For those who prefer concentrated coolants, the AMSOIL Propylene Glycol Antifreeze provides an eco-friendly alternative that lasts up to 5 years and offers superior corrosion and erosion protection.
The braking system on the Wagoneer benefits from AMSOIL Synthetic Brake Fluid, which is rated for both DOT 3 and DOT 4 specifications. This fluid maintains a stable viscosity across a wide temperature range, ensuring consistent pedal feel and preventing the sponginess associated with moisture absorption. It also offers excellent responsiveness for ABS and traction-control systems, contributing to overall vehicle safety.
Additional Maintenance and Protection
Beyond the essential fluids, several AMSOIL products can enhance the performance and appearance of your Wagoneer. For fuel system maintenance, the AMSOIL P.i.® Performance Improver Gasoline Additive is highly recommended. This additive can restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate after just one tank of fuel, helping to control pre-ignition knock and improve fuel economy. Additionally, the Upper Cylinder Lubricant provides protection for the fuel system and upper cylinders.
For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, while the Engine Fogging Oil protects internal engine components from rust during long periods of inactivity. These additives are ideal for protecting your investment during the off-season. General maintenance tasks are made easier with the AMSOIL Heavy-Duty Degreaser, which quickly removes grease and grime, and the Synthetic Multi-Purpose Grease, which offers outstanding low-temperature pumpability and load-carrying performance.
Keeping the vehicle looking its best is also important. The AMSOIL Miracle Wash offers a waterless wash and wax solution that repels dust and protects against UV rays, while the Exterior Ceramic Spray provides a rapid-shedding water barrier and UV protection. Interior care is handled by the Interior Detailers in Light Lemon or Scent-Free varieties, which trap and eliminate odors while providing UV protection.
About the 2022 Jeep Wagoneer
The 2022 Jeep Wagoneer represents a significant evolution for the iconic brand, marking a return to its full-size luxury SUV roots. Born from the legacy of the original Wagoneer that debuted in 1963, this modern iteration is built on the GA-L platform, a modular architecture shared with the Jeep Grand Cherokee but scaled up to accommodate larger dimensions and more powerful drivetrains. It sits squarely in the luxury body-on-frame segment, competing with vehicles like the Ford Expedition and the GMC Yukon Denali, yet it retains the rugged DNA that defines the Jeep brand.
Powered by a standard 5.7-liter HEMI V8 engine, the Wagoneer delivers robust performance suitable for both highway cruising and off-road excursions. With a towing capacity that can reach impressive figures when properly equipped, this vehicle is designed for families who need space without sacrificing capability. The interior features high-quality materials, advanced technology, and flexible seating configurations, including available seven and eight-passenger layouts. The “Wagoneer Series III” models, which were introduced shortly after the initial launch, further elevated the luxury experience with premium leather interiors and unique styling cues.
Owners of the 2022 Wagoneer often cite its smooth ride quality, combining the comfort of a luxury sedan with the utility of a truck-based SUV. However, like any complex mechanical system, the Wagoneer benefits from proactive maintenance. Common areas of concern for vehicle owners include managing heat in the cooling system during extended towing, maintaining engine cleanliness under high-load conditions, and ensuring the electrical limited-slip differential receives the correct lubricant. Using high-performance synthetic oils helps mitigate these risks by providing better thermal stability and superior cleaning properties compared to conventional oils.
Furthermore, the 5.7L engine, while reliable, is susceptible to carbon buildup on intake valves, a common issue in direct injection engines. This can lead to rough idling and reduced fuel efficiency over time. Incorporating fuel system treatments and using high-quality motor oils with strong detergent packages can help delay the onset of these issues. The transmission, with its sophisticated 8-speed design, also benefits from fluids that resist oxidation and shear down, ensuring long-term shift quality. By utilizing AMSOIL’s full spectrum of lubricants, owners can address these potential pain points, extending the life of their investment and ensuring the Wagoneer performs at its peak year after year.
Ultimately, the 2022 Jeep Wagoneer is a versatile and capable vehicle that serves as a flagship for the brand. Whether navigating city streets, hauling a trailer, or exploring rough terrain, the right lubricants make a difference. By choosing AMSOIL synthetic products, drivers ensure their Wagoneer is protected against the harsh demands of modern driving, delivering peace of mind and sustained performance.
