Engine Oil and Filtration Specifications

The heart of your 2023 Dodge Challenger lies in the 3.6L Pentastar V-6 engine. This powerplant is renowned for its reliability and versatility, but it demands precise lubrication to function at its best. The engine oil capacity for a complete change, including the filter, is 5.9 quarts. Owners should be aware that the oil drain plug torque specification is 20 ft/lbs, a critical detail for preventing thread damage during service. It is essential to check the oil level after refilling to ensure proper lubrication.

AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil is the top recommendation for this vehicle. It provides up to 25,000 miles of protection between changes, significantly exceeding standard intervals. The oil’s advanced technology helps maintain horsepower and reduces wear, making it ideal for spirited driving. For owners seeking extended protection without reaching the full 25,000-mile threshold, AMSOIL Extended-Life 5W-20 offers up to 20,000 miles of coverage. This formulation includes enhanced cleaning power to keep the engine running smoothly and is particularly beneficial for vehicles operated under severe conditions.

If you prefer a cost-effective solution that still utilizes 100% synthetic base stocks, AMSOIL OE 5W-20 is an excellent choice. It fights sludge and deposits effectively, ensuring the variable valve timing system operates without restriction. For Challenger owners with vehicles that have surpassed 75,000 miles, AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil introduces unique chemistry designed to condition seals, reduce consumption, and boost the cleaning power to manage higher levels of contaminants. All these oils meet the stringent requirements of the G (ERB G) engine code for the 2023 model year.

Filtration is equally critical. The AMSOIL Oil Filter (EA15K19) is designed to match the oil’s performance, filtering 99% of harmful contaminants at 20 microns. Its greater capacity for small, wear-causing particles helps reduce engine wear significantly. For those preferring an aftermarket option, the WIX Oil Filter (WL10010) is a compatible choice that offers premium media improvements over standard OEM filters, ensuring clean oil circulates through the engine. Both filters are compatible with the 3.6L engine and support extended service intervals when paired with AMSOIL synthetic motor oils.

Transmission and Drivetrain Lubricants

The 2023 Dodge Challenger’s automatic transmission systems require fluid that can withstand the rigors of high-torque output and heavy loads. Depending on the specific model, the transmission is either an 8HP50 or an 850RE. The total fill capacity for an 8HP50 is 9.5 quarts, while the 850RE requires 9.7 quarts for a total fill. These systems are sensitive to fluid quality, and maintaining the correct viscosity is vital for smooth shifting and longevity.

AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand heavy towing, elevated temperatures, and challenging terrain. It remains fluid even in sub-zero temperatures, ensuring instant shift response in winter. For a more budget-friendly option that still delivers 100% synthetic protection, AMSOIL OE Fuel-Efficient Automatic Transmission Fluid offers excellent protection against wear and is suitable for both transmission types.

For all-wheel-drive models, the transfer case (BW 44-40) requires lubrication as well. The capacity is approximately 2.1 pints. AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can be used effectively here. These fluids resist harmful sludge and promote smooth, shudder-free shifts. Additionally, for models equipped with power steering systems that utilize hydraulic fluid, the same multi-vehicle synthetic transmission fluids can often be used as a high-performance alternative, offering better protection against leaks and wear than conventional fluids.

The differential systems also demand specific synthetic lubricants to handle the high loads of the Challenger. The front differential (175 FIA) requires 1.3 pints of 75W-90 GL-5 synthetic oil. AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube is the optimal choice, featuring advanced protection against wear and rust while helping to reduce operating temperatures. The 75W-90 Long Life variant is another strong contender for those seeking extended service intervals.

For the rear axle, the requirements vary based on the specific axle assembly. The 195 Rear Axle requires 1.5 pints of 75W-85 GL-5 fluid. The 230 Rear Axle requires 2.3 pints, whether it is a standard or limited-slip differential. AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube is recommended for all these applications. It contains friction modifiers essential for limited-slip differentials, ensuring smooth operation and reducing the risk of axle wind-up. The SEVERE GEAR line also features excellent anti-wear properties and thermal control, keeping the axles cool and protected.

Coolant and Brake Fluid

Proper cooling system maintenance is essential to prevent overheating and corrosion in the aluminum engine block. The cooling system capacity for the 3.6L engine is 11.1 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mixed formulation that provides protection up to 150,000 miles or 5 years. It is compatible with all other antifreeze colors and free of phosphates, nitrates, and other additives that can cause deposits. For a non-toxic, environmentally friendly alternative, AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that requires mixing with distilled water. It offers superior corrosion protection and can extend service life significantly, even in heavy-duty applications.

Brake safety is paramount for any performance vehicle. The Dodge Challenger requires DOT 3 or DOT 4 compatible brake fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid delivers excellent ABS and traction-control responsiveness. Its synthetic formulation ensures a stable viscosity over a wide temperature range, preventing vapor lock and ensuring consistent pedal feel. This fluid outperforms conventional glycol-ether fluids in boiling point resistance, providing superior safety margins for spirited driving and repeated hard braking.

Additional Maintenance and Additives

To further enhance vehicle performance and longevity, AMSOIL offers a range of additives and care products. The AMSOIL P.i. Performance Improver is a potent gasoline additive that restores up to 14% horsepower by cleaning carbon deposits from GDI fuel injectors and combustion chambers. It helps improve fuel economy and reduces the need for higher-octane fuels. For vehicles that may sit idle for extended periods, AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, protecting against varnish and gum buildup. The AMSOIL Engine Fogging Oil is ideal for seasonal storage, providing a protective coating on internal components to prevent rust during inactivity.

For vehicle care, the AMSOIL Miracle Wash Waterless Wash and Wax Spray offers a convenient cleaning solution that repels dust and protects against UV rays. The AMSOIL Brake and Parts Cleaner effectively removes grease and oil from brake components without leaving residue, helping to eliminate squeal. Additionally, AMSOIL Heavy-Duty Degreaser is available for cleaning engine bays and other surfaces, while the Silicone Spray provides a dry lubricating film for rubber components, preventing cracks and locking out moisture.
