Engine Oil and Filtration Requirements

The heart of your 2023 Ram 1500 is the 5.7L V8 engine, which operates under a demanding schedule of power delivery and load-bearing capacity. To maintain peak efficiency, this engine requires an oil with a viscosity of 0W-20. The total capacity for a routine oil change, including the filter replacement, is 7.0 quarts. It is crucial to refill to the correct level and verify the oil level after the refill, as overfilling or underfilling can impact engine performance and longevity. When refilling, ensure the oil drain plug is torqued to 25 ft/lbs to prevent leaks or damage to the threads.

For those seeking the absolute highest level of performance and protection, AMSOIL Signature Series 0W-20 stands out. This 100% synthetic oil is formulated to offer up to 25,000 miles of protection, significantly outperforming industry standards in terms of resistance to horsepower loss and wear. It contains advanced additives that help prevent the formation of harmful deposits, ensuring the engine runs cleaner for longer. For vehicle owners who prioritize extended service intervals without sacrificing protection, the Extended-Life 0W-20 is an excellent alternative, delivering up to 20,000 miles of guaranteed protection with enhanced cleaning power to keep internal components free of carbon buildup and sludge.

For owners of 2023 Ram 1500s with over 75,000 miles on the odometer, the specific formulation of AMSOIL 0W-20 High-Mileage Motor Oil is highly recommended. This product contains a boosted detergent and dispersant package designed to clean existing deposits while reducing the likelihood of new sludge formation. It also features enhanced anti-wear additives and seal conditioning agents that help reduce oil consumption and prevent leaks, extending the life of older engines. Regardless of which motor oil you choose, pairing it with a high-quality filtration system is non-negotiable. The WIX Oil Filter (Code 57060) is the recommended filtration solution, offering premium media that outperforms standard OEM filters in capturing contaminants, thereby ensuring the oil circulating through your engine remains clean and effective.

Cooling System and Fluid Capacities

Proper thermal management is critical for the 5.7L Hemi engine, especially when the truck is subjected to towing or hauling heavy loads. The cooling system capacity for the 2023 Ram 1500 is approximately 18.3 quarts. Maintaining the integrity of the coolant is vital to prevent overheating, freezing, and corrosion of aluminum components, which are prevalent in modern engine designs. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a convenient, pre-mixed solution containing a unique poly-organic acid (OAT) formulation. This chemistry is designed to protect all cooling system metals, gaskets, and hoses from degradation. It is free of phosphates, nitrates, nitrites, silicates, borates, and amines, making it compatible with a wide range of vehicle systems. For those who prefer a concentrated option, AMSOIL Propylene Glycol Antifreeze offers a robust alternative that requires mixing with distilled water, providing up to 150,000 miles or five years of protection against metallic corrosion and erosion.

Transmission and Drivetrain Lubrication

The automatic transmission in the 2023 Ram 1500 is a sophisticated 8-speed unit (8HP75) that demands precise fluid characteristics to ensure smooth shifting and long-term durability. A total fill for this transmission requires 9 quarts of fluid. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and elevated operating temperatures while remaining fluid in sub-zero conditions. It provides a reserve of protection during severe use, ensuring that the transmission operates smoothly even under extreme stress. For those seeking a more budget-friendly option that still meets high standards, AMSOIL OE Fuel-Efficient Automatic Transmission Fluid offers excellent protection against wear and sludge, promoting smooth, shudder-free shifts.

For four-wheel-drive models, the transfer case and differentials require specific attention to lubrication. The transfer case capacity varies by model, with the BW 48-11 requiring approximately 3.6 pints, the BW 48-13 requiring 3.8 pints, and the BW 48-12 requiring 2.7 pints. Fill these components to the bottom edge of the fill plug opening, ensuring the drain and fill plugs are torqued correctly. The differential lubrication depends on the specific axle ratio and whether a limited-slip differential (LSD) is present. For standard differentials, AMSOIL SEVERE GEAR 75W-90 is a versatile choice that controls thermal runaway and protects against rust. For rear axles with a Max Tow package or specific gear ratios like 3.92, AMSOIL SEVERE GEAR 80W-90 or AMSOIL SEVERE GEAR 75W-140 may be required, often in conjunction with a Mopar limited-slip additive (MS-10111) for LSDs. These synthetic gear lubes contain friction modifiers that prevent chatter and ensure consistent performance, while also reducing operating temperatures and extending the life of seals and gears.

Brake Fluid and Additional Maintenance

Ensuring the safety and responsiveness of your 2023 Ram 1500 is equally important as engine performance. The recommended brake fluid is a hydraulic brake fluid compatible with Mopar DOT 3 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. Unlike conventional brake fluids, its synthetic composition ensures a stable viscosity over a wide temperature range, preventing fade and maintaining pedal feel in demanding stop-and-go traffic or downhill descents.

Beyond the core lubrication needs, there are several additional products that can enhance the maintenance routine for this vehicle. For seasonal storage, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting ethanol corrosion and preventing varnish buildup. To protect the engine during long periods of inactivity, AMSOIL Engine Fogging Oil provides a rust-preventive coating for internal components. For those looking to restore lost power and improve fuel economy, AMSOIL P.i. Performance Improver Gasoline Additive can restore up to 14% horsepower and clean fuel injectors, including GDI types. AMSOIL Upper Cylinder Lubricant adds a layer of protection to the fuel system and upper cylinders, which is particularly beneficial for engines prone to carbon buildup.
