Maintaining the 2023 Dodge Challenger with the 5.7L HEMI engine requires lubricants that can handle high horsepower and varying driving conditions. Whether you are driving a daily commuter or pushing the vehicle to its limits, using the correct oil grade, filter, and fluid is essential for protecting the engine from wear and extending the service life of the vehicle. The engine is designed to operate on 0W-20 viscosity, and adhering to manufacturer recommendations ensures optimal performance and fuel efficiency.

For the 2023 Dodge Challenger with the 5.7L 8-cylinder engine, the engine oil capacity is 7.0 quarts when changing with a filter. The recommended oil grade is 0W-20. Drivers should torque the oil drain plug to 20 ft/lbs during reinstallation to ensure a secure seal without damaging the threads. Checking the oil level after refilling is a critical step to verify proper lubrication levels.
Moving beyond the engine, the cooling system requires careful attention to prevent overheating and corrosion. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant capacity for the 2023 Challenger is 14.7 quarts. AMSOIL offers two primary antifreeze options for this application: the Passenger Car & Light Truck Antifreeze & Coolant and the Propylene Glycol Antifreeze & Engine Coolant. Both formulations are designed to exceed original equipment manufacturer requirements, providing protection for up to 150,000 miles or five years. The propylene glycol formulation is a 50/50 pre-mix, while the propylene glycol version is concentrated and requires mixing with distilled water.
Transmission maintenance is equally vital for this power muscle. The 8-speed automatic transmission (8HP70) has a total fill capacity of 9 quarts. Using a high-quality synthetic fluid like the AMSOIL Signature Series Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid or the OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid ensures the transmission operates smoothly under load. For those with a manual transmission (TR6060), the capacity is 6.8 pints, and the Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid serves as a suitable lubricant. The fluid resists sludge and maintains performance in extreme cold.
The braking system requires a fluid that maintains stability over a wide temperature range. The Dodge Challenger utilizes Mopar DOT 3 hydraulic brake fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement that enhances responsiveness for ABS and traction control systems. It prevents the boiling points typically associated with conventional fluids during heavy braking.
Regarding the differential, synthetic oil is required for both the front and rear axles. The front standard differential (175 FIA) has a capacity of 1.3 pints, while the rear axle capacities vary by specific model. The 195 Rear Axle requires 1.5 pints, the 230 Rear Axle requires 2.3 pints, and the 230 LSD Rear Axle also requires 2.3 pints. For all these GL-5 limited slip and standard applications, AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube and SEVERE GEAR® 75W-85 100% Synthetic Gear Lube are recommended to control thermal runaway and protect against rust and corrosion. The 75W-85 variant is specifically noted for the rear 195 and 230 axles.
