The 2022 Dodge Durango equipped with the powerful 6.4L HEMI V-8 (Engine Code J ESG J) demands fluids that can withstand high thermal loads and provide superior protection under stress. As a high-performance SUV capable of heavy towing and spirited driving, the engine and transmission require synthetic lubricants that maintain viscosity and film strength in extreme temperatures. Using the correct oil capacity and filter ensures that you are maximizing the engine’s lifespan while maintaining peak efficiency. The following guide details the specific AMSOIL products recommended for a complete service on this vehicle.
Recommended AMSOIL Products
- AMSOIL Signature Series 0W-40 100% Synthetic Motor Oil – The premier choice for the 6.4L HEMI, offering exceptional protection against wear and horsepower loss for up to 25,000 miles or one year.

Proper lubrication is critical for the longevity of the 2022 Durango’s 6.4L engine. This naturally aspirated V-8 generates significant heat, and synthetic motor oil like the Signature Series 0W-40 maintains its viscosity better than conventional oils under these conditions. The oil capacity for this engine is 7.0 quarts when the filter is replaced, requiring a precise mix to ensure proper lubrication of the valvetrain and crankshaft. Paired with the AMSOIL Oil Filter, which features 99% filtration efficiency at 20 microns, the engine is kept free from abrasive particles that cause premature wear. While the AMSOIL filter is highly recommended, the WIX Oil Filter serves as a premium alternative for those seeking a different brand while maintaining superior media quality.
Transmission and Drivetrain Protection
The transmission in this Durango model is the 8-speed automatic (8HP70). This gearbox is subjected to significant stress during towing or aggressive acceleration, making the choice of fluid vital. The recommended Signature Series Fuel-Efficient Automatic Transmission Fluid offers enhanced thermal stability and shear resistance, protecting internal components from the wear associated with the high torque output of the HEMI V-8. The total fill capacity for the transmission is approximately 8.8 quarts, though a drain and fill will not reach this total; topping off may be required for a complete service. For a more budget-friendly yet high-performance option, the OE Fuel-Efficient Automatic Transmission Fluid is an excellent substitute that resists sludge and promotes smooth shifts without shudder.
The drivetrain includes front and rear differentials and a transfer case that also benefit from synthetic lubricants. The front differential requires 1.7 pints, while the rear differential varies slightly depending on the specific configuration (ELSD or non-ELSD), requiring between 1.9 to 2.7 pints. Regardless of the specific differential model, the SEVERE GEAR® 75W-85 is the ideal choice. This fluid contains specialized friction modifiers for limited-slip differentials and controls operating temperatures to prevent thermal runaway. Similarly, the transfer case, which requires 4 pints, can utilize the Signature Series Multi-Vehicle Automatic Transmission Fluid or the OE Multi-Vehicle variant to ensure smooth power distribution to all four wheels.
Cooling and Brake Fluids
With a cooling system capacity of 16.4 quarts, maintaining the correct coolant mixture is essential to prevent overheating, especially when towing. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate, nitrate, and silicate-free formulation that is compatible with all other coolant colors. It offers protection up to 150,000 miles or five years. For those who prefer a concentrate that allows for a higher freeze protection ratio or easier top-offs, the Propylene Glycol Antifreeze provides up to 150,000 miles of protection and greatly surpasses OEM corrosion standards. Additionally, the braking system benefits from the AMSOIL DOT 3 and DOT 4 Brake Fluid, which ensures responsive pedal feel and superior resistance to boil-over during heavy stopping.
Additional Maintenance Considerations
Beyond the core engine and drivetrain fluids, the air intake system plays a crucial role in engine efficiency. The WIX Air Filter is recommended to ensure clean airflow to the 6.4L engine. For power steering, the vehicle utilizes an electric power steering system (EPS) in most configurations, where the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid helps maintain seal integrity and reduces friction. If the vehicle has been stored for extended periods, using the AMSOIL Gasoline Stabilizer can keep the fuel fresh for up to 12 months, protecting the fuel system from ethanol corrosion and varnish buildup. Similarly, the AMSOIL P.i. Performance Improver can be used to restore up to 14% horsepower and clean fuel injectors.
About the Vehicle
The 2022 Dodge Durango stands as a benchmark in the mid-size SUV segment, offering a rare combination of rugged capability and sporty performance. Built on the same platform as the Jeep Grand Cherokee, it shares much of its mechanical underpinnings with the high-performance Jeep trackhawk lineage, which explains its robust towing capacity and sturdy chassis. The Durango is widely celebrated for its versatility; it can comfortably seat up to seven passengers while offering a surprisingly agile driving dynamics for a vehicle of its size. For the 6.4L V-8 model, the driving character is defined by raw, naturally aspirated power. Unlike many modern engines that rely heavily on turbocharging to generate torque, the 6.4L HEMI V-8 delivers a linear and responsive power curve that enthusiasts and families alike appreciate for its predictability and sheer force.
This specific engine code, the 6.4L with the “J” designation, is part of the third-generation Durango production run, which began in 2011 and has seen continuous refinements through the 2020s. The vehicle is known for its “Supercharged” V-8 variants (the Hellcat models), but even the naturally aspirated 6.4L version packs over 475 horsepower, making it one of the most powerful non-turbo V-8 engines available in a family SUV. The Durango’s design, by Italian coachbuilder Tom Gale, is iconic, featuring the signature cross-hatch grille and a muscular stance that has remained consistent for over a decade. Its market position is unique, often competing against three-row crossovers that sacrifice towing capacity for fuel economy, whereas the Durango remains true to its truck roots with a body-on-frame design heritage (though now unibody construction) that supports substantial payloads.
Owners of the 6.4L Durango often encounter specific maintenance challenges related to the high-thermal environment of the engine. One common issue is the stress placed on the cooling system during summer towing; overheating can occur if the coolant mixture is not optimal, which is why the specialized AMSOIL Antifreeze is so effective at dissipating heat. Another frequent problem involves the automatic transmission; the 8HP70 gearbox can develop shudder or harsh shifts under heavy load if the fluid degrades. Synthetic transmission fluid helps mitigate this by maintaining consistent viscosity and friction characteristics. Additionally, the front differential and transfer case can experience noise or wear due to the constant torque transfer in 4×4 models; the SEVERE GEAR® 75W-85 lubricant is specifically designed to handle the high shear forces in these components. Finally, the HEMI engines are known to be susceptible to carbon buildup on intake valves over time, particularly with direct injection characteristics in later models. Regular use of the AMSOIL P.i. fuel additive can help prevent this carbon accumulation, maintaining fuel flow and engine cleanliness for the long haul.
