The 2022 Dodge Challenger with the 3.6L Pentastar V-6 engine is a classic American muscle car that balances aggressive styling with everyday usability. Keeping this vehicle running at its peak requires more than just filling the tank; it demands the right lubricants tailored to its specific engineering needs. The 3.6L ERB engine operates under high stress, particularly when enthusiasts take it spirited driving on the highway or the track. Using the correct viscosity and quality of oil ensures that internal components stay protected against wear, sludge, and the extreme temperatures generated during spirited acceleration. Proper lubrication extends the life of the engine, maintains fuel efficiency, and preserves the performance characteristics that make this model a favorite among drivers.

Achieving peak performance from the 3.6L Pentastar engine requires a fluid strategy that goes beyond the bare minimum. This naturally aspirated V-6 is robust, but it benefits immensely from high-quality synthetic lubricants that can handle the thermal stress of sustained driving. When selecting motor oil, the 5W-20 viscosity is specified for all temperatures. A capacity of 5.9 quarts is required when the oil filter is changed, a critical detail often overlooked by DIY mechanics. After refilling, checking the oil level is essential to ensure the correct amount has been added. The oil drain plug should be torqued to 20 ft/lbs to prevent leaks without stripping the threads. For those who drive their Challenger hard, the AMSOIL Signature Series offers the most robust protection, capable of extending oil change intervals significantly while maintaining engine cleanliness.
The transmission in the 2022 Challenger is a crucial component, particularly given the car’s performance pedigree. Whether equipped with the 850RE or 8HP50 8-speed automatic, the total fill capacity ranges from 9.5 to 9.7 quarts. Using a high-performance synthetic automatic transmission fluid is vital to prevent shudder, ensure smooth shifts, and protect the complex valve body from wear. AMSOIL’s fuel-efficient synthetic options are engineered to remain fluid in sub-zero temperatures while withstanding the elevated heat generated during spirited driving. These fluids also provide a reserve of protection against the mechanical stress of heavy towing or challenging terrain, which is especially relevant for a rear-wheel-drive muscle car that may be used for weekend runs or track days.
The rear differential requires attention as well, as it is a high-stress component in any rear-wheel-drive vehicle. Depending on the specific axle ratio and differential type (standard, 195, or 230), the vehicle requires synthetic gear lube of either 75W-85 or 75W-90 viscosity. For limited-slip applications, the inclusion of friction modifiers in the synthetic gear lube is essential to prevent chattering and ensure smooth power delivery. The capacities vary slightly by axle, ranging from 1.3 to 2.3 pints, so using a precision synthetic lubricant helps ensure longevity and optimal performance across all driving conditions.
About the Vehicle
The 2022 Dodge Challenger is an iconic piece of American automotive history, carrying the torch of the original muscle car era into the modern age. Part of the sixth generation introduced in 2008, the Challenger has long been celebrated for its retro-futuristic design, which blends classic 1970s styling cues with contemporary technology and safety features. The specific 3.6L V-6 engine, known as the Pentastar, serves as the entry-level powertrain for the lineup, offering a balance of V-6 power and improved fuel economy compared to the massive V-8 and Hellcat options available in other trims. Despite being the “small” engine in the family, the 3.6L is a highly capable unit that provides sufficient torque and horsepower for spirited driving, making it a popular choice for enthusiasts who appreciate a responsive engine without the extreme power of the supercharged variants.
Owners of the Challenger often describe it as a car that turns heads every time it is driven. The interior features a classic, driver-focused cockpit with a modern infotainment system, while the exterior is defined by its distinctive grille, dual hood scoops, and aggressive stance. The 3.6L model is particularly valued for its daily drivability, making it a practical choice for those who want the muscle car experience without the high maintenance costs associated with the more powerful supercharged engines. However, like any performance vehicle, it demands proper care to prevent common issues that can arise from neglect or using inferior fluids.
One common problem that can affect the Pentastar engine, like many modern aluminum engines, is the buildup of carbon deposits in the intake valves and combustion chamber over time. This can lead to rough idling, reduced fuel economy, and a loss of power. Using high-quality synthetic motor oils that contain effective detergent packages helps minimize this buildup, and the addition of a performance fuel additive like the P.i. Performance Improver can restore fuel injectors and clean the intake system. Another potential issue with the 3.6L engine, particularly in higher-mileage vehicles, is the potential for oil consumption or sludge formation if conventional oil is used for extended periods. Synthetic oils are specifically formulated to resist oxidation and sludge, keeping the engine internals clean and reducing oil consumption over the life of the vehicle.
The 8-speed automatic transmission in the 3.6L Challenger is generally robust, but it can suffer from shudder or harsh shifting if the fluid degrades or becomes contaminated. Using a high-performance synthetic transmission fluid helps maintain the proper friction characteristics and thermal stability required for smooth operation, preventing the shudder issues that can occur as the fluid ages. Additionally, the limited-slip differentials often found on Challenger models can produce “chatter” or squealing noises during low-speed turns if the correct lubricant with friction modifiers is not used. This can be exacerbated by the use of conventional gear lube, which breaks down faster under the high loads experienced during hard acceleration. By using a premium synthetic gear lube designed for limited-slip differentials, owners can eliminate this noise and ensure the differential gears and clutches are adequately protected against wear. Proper maintenance of these fluids is the key to unlocking the full potential of the 2022 Dodge Challenger 3.6L, ensuring it remains a reliable and enjoyable daily driver for years to come.
