Maintaining your 2008 Dodge Durango with the 4.7-liter V8 engine requires precise fluid selection to ensure longevity and peak performance. The correct lubricants not only protect critical internal components from wear but also help manage the extreme temperatures and heavy loads this SUV was designed to handle. Whether you are towing, hauling heavy cargo, or driving in harsh winter conditions, using the right AMSOIL Signature Series, Extended-Life, or AMSOIL OE synthetic products can significantly extend the service life of your powertrain and drivetrain.

Understanding the specific needs of your 2008 Durango is the first step in a successful maintenance routine. The engine requires 6.0 quarts of oil, including the filter change. This capacity is critical to ensure all moving parts are adequately coated upon startup. Using a high-quality AMSOIL Oil Filter or a WIX Oil Filter in conjunction with the fluid ensures that the oil remains clean, trapping harmful particles that could accelerate engine wear. The AMSOIL OE Oil Filter and the WIX XP Oil Filter are both excellent choices that offer superior media to trap contaminants better than many standard OEM filters.
When it comes to the cooling system, the 2008 Durango requires a significant amount of fluid. Depending on whether the vehicle is equipped with a rear heater, the total capacity ranges from 13.1 to 14.2 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is engineered to exceed original equipment manufacturer requirements. It features a unique poly-organic acid (OAT) formulation that protects the cooling system metals and hoses from corrosion. Alternatively, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that requires mixing with distilled water, offering protection for up to 150,000 miles or five years in passenger cars and light trucks.
The transmission fluid is another vital component for the smooth operation of your Durango. For models equipped with the 42RLE 4-speed automatic transmission, the total fill capacity is 8.8 quarts, with an initial fill of 4 quarts. Vehicles with the 545RFE 5-speed automatic transmission require 14.1 quarts for a total fill (6.6 quarts initial fill for 4WD or 5.5 quarts for RWD). The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an ideal choice here, as it resists harmful sludge and provides excellent cold-weather performance. It guards against leaks and promotes smooth, shudder-free shifts, which is essential for a vehicle of this weight class. The WIX Transmission Filter is also available to help maintain the cleanliness of the fluid system.
Drivetrain and Safety Fluids
For the transfer case, the Lubrication requirements vary by model. The NV144 transfer case requires 1.7 pints, while the NV244 GENIII requires 3.4 pints. The AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is a suitable replacement for the transfer case fluid, ensuring protection against wear and excellent cold-weather performance. The front differential (C205F) calls for 3.4 pints of 75W-90 AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube, while the rear differential with the 9.25 RG axle requires 4 pints of 75W-140 AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube. The AMSOIL SEVERE GEAR line offers advanced protection against wear and helps reduce operating temperatures, which is crucial for the heavy-duty nature of the Durango.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is often overlooked but is essential for safety. The 2008 Durango requires DOT 3 or DOT 4 brake fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction-control systems. It maintains a stable viscosity over a wide temperature range, ensuring consistent braking performance regardless of the weather conditions or the frequency of braking events. Additionally, the power steering system relies on ATF+4, which can be effectively handled by the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid.
About the 2008 Dodge Durango
The 2008 Dodge Durango represents a significant era for the full-size SUV segment. Built on the Chrysler LH platform, this generation of the Durango was designed to bridge the gap between a rugged body-on-frame truck and a comfortable family hauler. With the 4.7-liter PowerTech V8 engine, owners enjoyed a robust powertrain capable of handling significant towing duties, a hallmark of the Durango’s reputation. The vehicle’s design focused on versatility, offering spacious interiors and a powerful presence on the road that appealed to families and work-oriented users alike.
Despite being a heavy vehicle, the Durango offered a surprisingly comfortable ride, thanks to its rear independent suspension setup which distinguished it from many competitors that used solid rear axles. This suspension design provided better handling and ride quality, making it a popular choice for those who needed a large vehicle without the harshness of a traditional truck. The 2008 model year, in particular, solidified the Durango’s status as a reliable workhorse, known for its durability and ability to handle various terrains. Owners appreciated the blend of capability and comfort, which allowed the vehicle to serve as a primary family car for long commutes or a dedicated towing machine for weekends.
Driving a 2008 Durango with the 4.7L engine often evokes memories of its strong low-end torque, which made it excellent for overtaking and pulling heavy loads. The vehicle’s interior was designed with a focus on functionality, featuring durable materials that could withstand the wear and tear of daily use. While it is a vehicle that requires regular maintenance, the 2008 Durango is widely regarded as a resilient machine that, with proper care, can provide many years of reliable service. Its robust construction and proven engine family make it a favorite among enthusiasts who value mechanical simplicity and raw capability over the latest electronic conveniences.
