The 2022 Dodge Charger equipped with the 5.7L 8-cylinder engine (Engine Code EZH) is a powerful American sedan known for its straight-six V8 heritage and potent performance capabilities. Ensuring this engine receives the correct lubrication is critical for maintaining its balance between daily drivability and high-performance potential. The EZH engine, often found in the SXT and R/T trims, relies on specific fluid capacities and viscosities to handle thermal stress and wear, especially given its 7-quart total capacity including the filter. Using the proper AMSOIL OE 0W-20 100% Synthetic Motor Oil not only protects the engine components from premature failure but also maximizes the vehicle’s efficiency and responsiveness.

Choosing the right oil for the 5.7L V8 is the first step in preserving the engine’s longevity. The factory recommends 0W-20 viscosity, and AMSOIL’s Signature Series 0W-20 100% Synthetic Motor Oil is formulated to outperform conventional oils and factory fills. It offers 75% more engine protection against horsepower loss and wear, which is particularly beneficial for the high-stress environment of a modern V8. For owners who drive under severe conditions or prefer extended drain intervals, this oil guarantees protection for up to 25,000 miles or one year, significantly reducing maintenance frequency while maintaining peak performance. If you are looking for a cost-effective alternative that still offers synthetic benefits, the AMSOIL OE 0W-20 provides an out-of-the-mill mileage solution that fights sludge and deposits effectively.
The cooling system in the 2022 Charger is equally vital to the engine’s health. With a capacity of approximately 14.7 to 15.1 quarts depending on the specific configuration, maintaining the correct AMSOIL Passenger Car & Light Truck Antifreeze & Coolant mixture is essential. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant uses a unique poly-organic acid (OAT) formulation that is compatible with all other antifreeze colors and free from phosphates, nitrates, and silicates that can harm the cooling system. This 50/50 pre-mix provides protection for up to 150,000 miles or five years, ensuring that the engine operates within the optimal temperature range regardless of whether you are facing sub-zero winters or sweltering summers.
Transmission health is critical in a vehicle of this caliber, as the 8HP70 8-speed automatic transmission is subjected to significant stress during acceleration and towing. For the 8-speed transmission, the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an excellent choice, offering reserve protection during heavy use and abuse. Conversely, for the NAG1 5-speed automatic found in some models, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is recommended. Both fluids are designed to resist harmful sludge, promote smooth, shudder-free shifts, and guard against leaks, ensuring the transmission remains responsive and reliable over the long term.
When it comes to the drivetrain, the 2022 Dodge Charger requires specific gear lubes for its differentials. The front standard differential (175 FIA) requires a GL-5 75W-90 synthetic oil, for which the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is perfectly suited. This product contains friction modifiers for limited-slip applications and helps reduce operating temperatures. For the rear differentials, whether it is the 195, 220, or 230 Axle, or a limited-slip setup, the AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube is the required lubricant. This specific viscosity is engineered to control thermal runaway and protect against rust and corrosion, extending the life of the seals and equipment. Alternatively, the SEVERE GEAR® 75W-110 is also available for specific axle applications.
Why Proper Lubrication Matters for This Engine
The 5.7L V8 engine is a robust powerplant, but like any internal combustion engine, it relies on a continuous film of oil to separate moving parts and dissipate heat. Without proper lubrication, friction increases, leading to accelerated wear, sludge buildup, and potential catastrophic failure. AMSOIL synthetic motor oils are formulated with advanced base oils and additive packages that provide superior thermal stability compared to conventional oils. This means the oil maintains its viscosity and protective properties even under the extreme heat generated by the Charger’s V8 engine. Additionally, the extended service intervals offered by AMSOIL allow owners to reduce the environmental impact of oil changes while saving time and money.
Furthermore, the synthetic formulation of these products helps in combating the specific challenges faced by this engine type, such as cold-start wear and high-RPM stress. The unique chemistry of AMSOIL oils ensures that the engine stays cleaner for longer, reducing the need for expensive engine flushes or premature rebuilds. By using the correct AMSOIL Oil Filter and fluids, you ensure that the Charger’s performance characteristics remain consistent throughout the life of the vehicle.
About the Vehicle
The 2022 Dodge Charger is a full-size sedan that occupies a unique position in the automotive market, blending the rugged character of a muscle car with the practicality of a four-door family vehicle. Powered by the 5.7L HEMI V8 in the models we are discussing, the Charger delivers a potent combination of acceleration and hauling capability. The vehicle is renowned for its aggressive styling, featuring a bold grille, sculpted hood, and wide stance that commands attention on the road. The 5.7L engine, often associated with the R/T trim level, provides a substantial amount of torque, making it ideal for highway cruising, spirited driving, and towing light loads.
Originating from the heritage of the legendary Plymouth and Dodge muscle cars of the past, the Charger has evolved into a modern performance sedan that appeals to a wide range of drivers. It is built on the LD platform, which allows for a spacious interior and a smooth ride quality despite the vehicle’s size. The interior is designed with driver focus in mind, offering comfortable seating and intuitive controls. The market position of the Charger is distinct, as it is one of the few remaining four-door sedans available with a naturally aspirated V8 engine, appealing to enthusiasts who prioritize raw power and sound over turbocharged alternatives.
Owners of the 2022 Dodge Charger often cite its powerful engine and distinctive looks as the primary reasons for their purchase. The vehicle’s ability to perform well in daily commutes while offering a thrilling driving experience on weekends makes it a versatile choice. However, like any performance vehicle, the Charger is not without its potential issues. Common problems that can arise with the 5.7L V8 include oil consumption, which can lead to low oil levels if not monitored, and carbon buildup on the intake valves due to direct injection technology. Using high-quality synthetic motor oil with advanced detergents can help mitigate these issues by keeping the engine internals cleaner and reducing the rate of deposit formation. Additionally, the AMSOIL P.i.® Performance Improver can help restore power and clean injectors.
Another common concern for V8 engines, particularly those used for spirited driving, is the degradation of transmission fluid under high thermal loads. The heat generated during aggressive driving can cause the fluid to break down, leading to harsh shifts or premature wear of internal components. Regular fluid changes with a high-performance synthetic automatic transmission fluid can extend the life of the transmission and maintain smooth shifting characteristics. Additionally, owners may experience issues with the cooling system, particularly in hotter climates or during heavy towing, where the standard coolant may not provide sufficient protection against boiling over. Using a premium antifreeze with extended service life can prevent overheating and corrosion in the cooling system.
Finally, the braking system on a heavy, powerful vehicle like the Charger is subject to significant stress. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid can absorb moisture over time, leading to a lower boiling point and potential brake fade during hard stops. Switching to a synthetic brake fluid with a higher boiling point can improve brake pedal feel and ensure consistent stopping power. By addressing these common areas of concern with the right lubricants and additives, owners can enjoy the full potential of their 2022 Dodge Charger while minimizing the risk of costly repairs and maintenance issues.
