The HEMI 5.7L V8 engine is renowned for its power and torque, but it also operates at high temperatures. The oil pump circulates the fluid through tight tolerances, and the high-output nature of the engine can generate significant heat. Standard conventional oils may break down faster under these conditions, leading to increased wear on lifters, cams, and bearings. AMSOIL 0W-20 motor oil flows instantly at startup to protect critical components before the engine reaches full operating temperature. The Signature Series variant is particularly beneficial for owners who frequently tow trailers or drive in extreme climates, as it maintains its protective film strength even when the oil film is subjected to high shear forces. Additionally, the Extended-Life formula offers a balance of performance and longevity for drivers who prefer standard maintenance schedules over maximum intervals, ensuring the engine remains clean and free of deposits that can cause premature wear.
Maintenance of the transmission is equally critical for the 2022 Durango. The 8-speed automatic transmission (8HP70) is a sophisticated component that relies on the correct fluid viscosity to ensure smooth shifts and efficient power delivery. AMSOIL transmission fluids are engineered to handle the rigors of heavy towing and stop-and-go traffic without losing their viscosity index. Unlike some traditional fluids that may thicken or thin out significantly with temperature changes, the synthetic options remain stable, providing consistent torque converter lockup and precise shifting. This stability helps reduce transmission shudder, a common issue in automatic transmissions under load, and extends the life of clutches and bands. For the 2022 model year, the capacity for a total fill is approximately 8.8 quarts, but owners should verify the exact level after refilling to ensure optimal operation.
Essential Fluids for Drivetrain and Braking Systems
The drivetrain of the Durango, including the transfer case and differentials, also requires specific lubrication to handle the distribution of power to all four wheels. The front and rear differentials utilize limited-slip components in many configurations. AMSOIL SEVERE GEAR 75W-85 synthetic gear lube is formulated with friction modifiers specifically designed for these limited-slip applications. This ensures smooth engagement and prevents the chatter or squeal that can occur with non-synthetic or improperly formulated gear oils. The fluid also helps control thermal runaway, a condition where heat generation increases friction and temperature in a dangerous feedback loop, ensuring the gears run cooler and longer. Capacity for the differentials varies based on the specific gear ratio and options, with the front typically holding around 1.7 pints and the rear varying between 1.9 and 2.7 pints depending on the specific model and the presence of an Electronic Limited Slip Differential (ELSD).
Braking performance is another area where synthetic fluid makes a noticeable difference. The Durango’s braking system benefits from AMSOIL DOT 3 and DOT 4 synthetic brake fluid, which resists moisture absorption better than traditional fluids. This property is vital for preventing the boiling of the fluid under heavy braking, which can lead to a spongy pedal and reduced stopping power. The synthetic formulation ensures a stable viscosity, providing consistent pedal feel in both freezing winters and scorching summers. For vehicles equipped with electric power steering, AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid offers excellent protection against heat and helps seals remain soft to prevent leaks. If the vehicle is equipped with a hydraulic power steering system instead, the Signature Series Multi-Vehicle Automatic Transmission Fluid can be used as a compatible alternative to maintain the system’s health. Proper maintenance of these fluids ensures safety and reliability, allowing the driver to focus on the road without worrying about fluid failure.
Cooling system health is paramount for the longevity of the HEMI engine. The 2022 Durango requires a specific type of antifreeze to protect the aluminum components and the various metals within the cooling system. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, and silicate-free OAT formulation that is compatible with all colors of antifreeze. This eliminates the risk of chemical reactions when mixing fluids, a common cause of cooling system failure. The fluid protects against corrosion and erosion, ensuring that the radiator and heater core remain free of scale and deposits that can impede heat transfer. With a capacity of approximately 15.4 to 16.1 quarts, it is important to follow the manufacturer’s refill instructions and check the level carefully to avoid air pockets in the system. Using the Propylene Glycol Antifreeze is also an option for those who prefer a different chemical base, offering extended protection up to 150,000 miles or five years.
About the Vehicle
The 2022 Dodge Durango represents the culmination of the third-generation SUV platform, which has been a staple in the American automotive market since its introduction. Known for its bold styling and boxy, muscular aesthetic, the Durango appeals to families and adventurers alike who require a blend of rugged capability and everyday usability. At its heart lies the choice of powerful engines, with the 5.7-liter HEMI V8 being a favorite for those who need significant towing capacity and acceleration. This engine produces a substantial amount of torque, making it ideal for hauling loads, camping gear, or even a boat, while still providing the smooth, responsive power that drivers expect from a premium SUV.
Owners of the Durango often praise the vehicle for its spacious interior, which offers seating for up to seven passengers and ample cargo space. The three rows of seats can be folded flat to create a massive load floor, enhancing the vehicle’s versatility for road trips or hauling large items. The interior design emphasizes a blend of modern technology and durable materials, catering to both tech-savvy drivers and those who value traditional utility. The infotainment systems available in the 2022 model year provide seamless connectivity, making it easier to navigate and stay entertained during long drives. The ride quality is generally considered comfortable, with a suspension setup that balances handling with a smooth ride over rough roads.
However, like any high-performance vehicle, the Durango does have some known issues that owners should be aware of. One common concern involves the transmission, where some drivers have reported shuddering or harsh shifting, particularly at lower speeds. Using a high-quality synthetic transmission fluid can help mitigate these issues by providing better lubrication and smoother engagement of the clutch packs. Another potential problem area is the fuel system, where carbon buildup on intake valves and injectors can affect performance over time. This is particularly relevant for direct injection engines, where fuel does not wash over the valves, leading to deposit accumulation. AMSOIL P.i. Performance Improver can help restore injectors and reduce deposits, while Upper Cylinder Lubricant can help prevent this buildup and maintain optimal fuel economy and power output. Additionally, some owners have noted issues with the air conditioning system, where leaks or compressor failures can occur, highlighting the importance of using the correct antifreeze and coolant. Finally, electrical gremlins, such as sensor failures or battery drain, have been reported by some owners, which underscores the value of maintaining clean electrical connections. By addressing these common areas with high-performance synthetic lubricants and additives, Durango owners can significantly extend the life of their vehicle and maintain its performance for years to come.
