Keeping your 2023 Chrysler 300 running smoothly requires more than just filling a tank with gas; it demands a comprehensive approach to fluid maintenance. This full-size sedan is powered by a robust 3.6L Pentastar V6 engine, which relies on precise lubrication to handle everything from daily commuting to spirited highway driving. Because this engine operates under varying thermal and mechanical stresses, using the correct viscosity and specification of fluids is essential for maintaining fuel economy, reducing wear, and extending the vehicle’s operational life. Neglecting these fluid systems can lead to premature component failure, reduced efficiency, and costly repairs.
The following guide details the specific lubrication requirements for this vehicle, focusing on engine oil, transmission fluid, gear lubes, and coolant. By adhering to these recommendations, owners ensure that their Chrysler 300 operates within the parameters designed by the manufacturer while potentially exceeding standard service intervals with high-performance synthetic alternatives.

When selecting motor oil for the 2023 Chrysler 300 3.6L, the engine code [G] ERB 3 dictates a 5W-20 viscosity grade for all temperatures. The total fluid capacity for the engine, including the filter change, is 5.9 quarts. After filling, it is critical to check the oil level to ensure accuracy. The oil drain plug torque specification should be set to 20 ft-lbs. For owners of this vehicle, the primary recommendation is the AMSOIL Signature Series 5W-20. This product stands out for its advanced chemistry, offering 75% more engine protection against horsepower loss and wear compared to standard synthetic oils. It is tested to provide up to 25,000 miles of protection between changes, making it an ideal choice for those looking to maximize maintenance intervals without compromising engine safety.
For those who prefer a balance of performance and value, the AMSOIL Extended-Life 5W-20 provides 20,000 miles of guaranteed protection. This formulation includes enhanced cleaning agents that help keep the engine running smoother and longer. It is particularly effective at preventing Low-Speed Pre-Ignition (LSPI), a common concern in modern turbocharged and direct-injection engines. If your vehicle has accumulated significant mileage, the AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil is the optimal choice. With a boosted detergent package and enhanced anti-wear additives, this oil helps reduce sludge by 67% and can improve engine performance in older vehicles.
Matching the oil with a high-quality filter is just as important as the oil itself. The recommended AMSOIL Oil Filter (EA15K19-EA) allows for lower restriction, ensuring that engine parts remain well-lubricated even under high-flow demands. It offers greater capacity for capturing small, wear-causing contaminants than competing filters, further reducing engine wear. Alternatively, the WIX Oil Filter (WL10010-EA) is a premium alternative with media improvements over OEM-branded filters, providing a reliable choice for maintenance.
Moving beyond the engine, the transmission system in the 3.6L engine model utilizes an 8-speed automatic transmission (850RE/SL076). This complex system requires fluid that can maintain viscosity under heavy loads and extreme heat. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed specifically for this application. It resists thermal breakdown and remains fluid in sub-zero temperatures, ensuring smooth shifts and protecting the transmission from wear during heavy towing or challenging terrain. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers a robust alternative that protects against wear and resists harmful sludge formation.
The cooling system holds 10 quarts of fluid. Proper coolant is vital to prevent overheating and corrosion. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, silicate-, borate-, and amine-free formula that protects all cooling system metals, gaskets, and hoses. It is a 50/50 pre-mix formulation that provides up to 150,000 miles of protection. For those who prefer concentrated coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers excellent protection and is compatible with various antifreeze colors.
For the differential and transfer case lubrication, the specific requirements vary by axle type. The front axle (175 FIA) requires 1.3 pints of lubricant, while the rear axle (195 or 220) typically requires 1.5 to 2.3 pints depending on the specific configuration (e.g., 195 Rear Axle, 220 Rear Axle, or 230 LSD Rear Axle). The recommended specification for these differentials is GL-5. The AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube is a superior choice for limited-slip differentials, as it contains friction modifiers to prevent shudder and protects against rust and corrosion. For applications requiring specific viscosities, the AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube or 75W-110 can be utilized. These products control thermal runaway and help reduce operating temperatures, extending the life of the oil, seals, and equipment.
Finally, the braking system relies on AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid. This fluid provides excellent ABS and traction-control responsiveness and maintains stable viscosity over a wide temperature range, ensuring consistent pedal feel and safety. By utilizing these specialized fluids, owners can maintain the performance and reliability of their 2023 Chrysler 300 for years to come.
