The 2023 Ram ProMaster 2500 with the 3.6L Pentastar V-6 engine is a workhorse built for heavy loads and demanding commercial applications. While this engine is robust, it requires precise lubrication to maintain performance, especially when subjected to the rigors of daily hauling or extreme weather conditions. Using the correct oil viscosity, such as the manufacturer-recommended 0W-20, ensures optimal engine protection, fuel economy, and longevity. Beyond the engine, the vehicle’s 9-speed automatic transmission and cooling system also depend on specialized fluids to function reliably. This guide provides a comprehensive breakdown of the recommended AMSOIL products to keep your ProMaster 2500 in top condition.

Proper lubrication is the cornerstone of maintaining the 2023 Ram ProMaster 2500’s reliability. The 3.6L engine, known for its versatility and power, operates under significant thermal stress, particularly when used for commercial purposes. Conventional oils may break down under these conditions, leading to increased wear, reduced fuel economy, and costly repairs. AMSOIL synthetic motor oils are engineered to withstand these extremes, offering superior resistance to oxidation and thermal breakdown. By selecting the correct 0W-20 viscosity, you ensure that the engine receives adequate lubrication during cold starts while maintaining film strength at operating temperatures.
The maintenance schedule for this vehicle includes more than just an oil change. The cooling system is vital for preventing overheating, especially during heavy hauling. The 2023 ProMaster 2500 requires 10.6 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Whether you choose the pre-mixed Passenger Car & Light Truck Antifreeze or the concentrated Propylene Glycol Antifreeze, both formulations are phosphate-free and designed to protect gaskets, hoses, and metals from corrosion. Extending the life of your cooling system helps avoid costly failures that can leave your vehicle out of service.
Transmission health is equally critical. The 9-speed automatic transmission (948TE) in this model benefits from high-quality synthetic fluid. For applications involving heavy towing or driving in extreme temperatures, the AMSOIL Signature Series Fuel-Efficient transmission fluid offers exceptional performance. It remains fluid in sub-zero conditions while providing a protective layer against the heat and stress generated by the transmission. The AMSOIL OE Fuel-Efficient option serves as a robust alternative that still meets the demands of modern automatic transmissions, protecting against wear and ensuring smooth shifting over extended intervals.
Maintenance also extends to the braking system and general vehicle care. The ProMaster 2500 utilizes hydraulic brakes that require high-performance AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid to maintain consistent pedal feel and responsiveness. The AMSOIL DOT 3 and DOT 4 Brake Fluid is compatible with the system and offers a stable viscosity that prevents fading under heavy use. Beyond essential fluids, owners can utilize AMSOIL additives like the P.i.® Performance Improver to restore horsepower and clean fuel injectors, or the AMSOIL Engine Fogging Oil for long-term storage protection. Regular use of these products ensures the vehicle remains ready for any task.
