The 2009 Dodge RAM 2500 HD Pickup, equipped with the robust 5.7L V8 engine (Engine Code [T] EZC T), is a powerhouse built for heavy-duty tasks, but its longevity depends heavily on consistent and high-quality lubrication. This engine features Multiple Displacement System (MDS) technology, which requires specific viscosity oils to ensure proper operation across varying temperatures. Using the correct fluids not only protects against wear but also maintains fuel efficiency and power output when the vehicle is under load, towing, or hauling. For owners of this legendary truck, selecting the right AMSOIL synthetic lubricants ensures comprehensive protection for the engine, transmission, and differentials, maximizing the vehicle’s performance and extending the service life of critical components.

Maintaining the proper lubrication schedule for the 2009 Dodge RAM 2500 HD is critical, especially for the 5.7L V8 engine which utilizes a Multiple Displacement System (MDS). This system improves fuel economy by shutting down cylinders under light loads, but it relies on precise oil viscosity to function correctly. For this vehicle, SAE 5W-20 is the mandatory viscosity. The engine requires 7.0 quarts of oil when the filter is changed. It is vital to check the oil level after the refill and torque the oil drain plug to 25 ft/lbs. The AMSOIL Signature Series 5W-20 is the premier choice, offering up to 25,000 miles of protection, while the Extended-Life 5W-20 provides up to 20,000 miles. For owners of trucks with higher mileage, the High-Mileage 5W-20 helps reduce consumption and sludge, ensuring the engine remains responsive.
Beyond the engine, the cooling system plays a vital role in managing the heat generated by this heavy-duty powerplant. The 2009 RAM 2500 HD requires 18.7 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. The pre-mix offers convenience and protection for up to 150,000 miles, while the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is ideal for heavy-duty applications seeking extended performance and meets rigorous corrosion standards.
Transmission maintenance is equally important for this truck, particularly given the heavy-towing capabilities. For models equipped with the 545RFE automatic transmission (both RWD and 4WD), the total fill capacity is 16.9 quarts. AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is highly recommended for its ability to handle elevated temperatures and heavy loads, while the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers a cost-effective alternative that resists sludge and promotes smooth shifting. A WIX Transmission Filter should be used during the service to ensure contaminants are removed effectively. Manual transmissions, such as the G56, require 10.8 pints of fluid and can utilize the same AMSOIL automatic transmission fluids for superior performance.
For the drive train, the 2009 RAM 2500 HD features various transfer cases and differentials that require specific gear lubes. Transfer cases like the NV241, NV243, NV244 GENII, NV271, and NV273 require specific capacities ranging from 3.4 to 4 pints. Differential lubrication depends on the axle type; the 9.25 and 10.25 rear axles (Open or Limited Slip) generally require 75W-90 or 75W-140 synthetic gear lubricants, while some front differentials require 75W-90. AMSOIL SEVERE GEAR lubricants in 75W-90, 75W-110, 80W-90, and 75W-140 viscosities provide the necessary protection against wear, rust, and thermal runaway. The 75W-90 is particularly versatile for limited-slip applications, and the 75W-140 is ideal for the rear differentials of 5.7L engines to handle heavy loads and prevent operating temperature spikes.
Finally, maintaining the brake system and fuel system ensures safety and efficiency. The truck utilizes DOT 3 hydraulic brake fluid meeting MS-4574 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers superior stability and responsiveness. For those who store their vehicle seasonally or want to improve engine performance, AMSOIL P.i. Performance Improver Gasoline Additive can restore up to 14% horsepower and clean GDI injectors, while the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months during storage.
