Engine Oil and Filter Recommendations
Selecting the right oil for the 2009 Dodge Challenger 3.5L is critical for ensuring long-term engine health. The engine requires 6.0 quarts of lubricant when the filter is changed. For those seeking the absolute best in wear protection, the AMSOIL Signature Series 10W-30 is an ideal choice. This 100% synthetic motor oil is formulated to deliver 75% more engine protection against horsepower loss and wear compared to conventional standards. It offers guaranteed protection for up to 25,000 miles or one year, making it a top-tier option for drivers who want to minimize maintenance frequency without compromising on safety.
If you prefer a balance between performance and value, the AMSOIL Extended-Life 10W-30 provides up to 20,000 miles of protection. It features 37% more cleaning power to help keep the engine running smoother and longer, which is particularly beneficial for older vehicles or those subjected to stop-and-go driving. For owners who drive their Challenger under severe conditions or simply want a reliable, cost-effective synthetic option, the AMSOIL OE 10W-30 is a solid choice. It is trusted by professional engine builders and is designed to fight sludge and deposits effectively.
When the Challenger has surpassed the 75,000-mile mark, maintaining engine seal integrity and cleaning power becomes even more important. The AMSOIL 10W-30 100% Synthetic High-Mileage Motor Oil is specifically engineered for these vehicles. Its unique chemistry includes boosted detergent and dispersant packages that help reduce sludge by 67%, while enhanced anti-wear additives protect engine components. This oil provides guaranteed protection for 12,000 miles or one year, ensuring that your high-mileage Challenger continues to perform like new.
Pairing your oil with a high-quality filter is just as important. The AMSOIL Oil Filter is rated for 99 percent filtering efficiency at 20 microns, allowing for lower restriction and keeping engine parts lubricated. It also offers greater capacity for small, wear-causing contaminants than competing filters. If you prefer a widely available brand, the WIX Oil Filter is a reliable alternative that offers premium media improvements over original equipment manufacturer-branded filters.
Transmission and Differential Fluids
The 2009 Dodge Challenger 3.5L comes equipped with an automatic transmission, specifically the 42RLE model. Keeping this transmission fluid in peak condition is essential for smooth shifting and longevity. The system requires 8.8 quarts for a total fill. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is highly recommended for this application. It is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero temperatures. This ensures reserve protection during heavy use and abuse.
For those who do not require the extreme performance levels of the Signature Series, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers excellent protection. It is formulated to resist harmful sludge, guard against leaks, and promote smooth, shudder-free shifts. This fluid provides a stable performance profile that meets the needs of most Challenger owners.
For the rear differential, which is a standard unit requiring GL-5 lubrication, AMSOIL SEVERE GEAR 75W-140 100% Synthetic Gear Lube is the appropriate choice. The differential holds 2.5 pints of fluid. This synthetic gear lube is designed to control thermal runaway and protect against rust and corrosion. It also contains friction modifiers suitable for limited-slip applications, helping to reduce operating temperatures and extend the life of seals and equipment.
Cooling and Brake Systems
Maintaining the cooling system is vital for the 3.5L engine, which operates efficiently across a wide range of temperatures. The system capacity is 11.1 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that is engineered to exceed original equipment manufacturer requirements. It protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or five years.

About the Vehicle
The 2009 Dodge Challenger represents a unique era in American automotive history, reviving the legacy of the classic muscle car from the late 1960s and early 1970s. Launched by Chrysler in late 2008 as a 2008 model (often associated with the 2009 model year in terms of widespread availability and sales), the Challenger was a direct response to the retro-modern muscle car market. It was designed to compete with vehicles like the Ford Mustang and Chevrolet Camaro, offering a blend of classic styling cues and modern technology.
The 2009 model year specifically introduced the Challenger to a new generation of enthusiasts. The vehicle is built on the LH platform, which was a front-engine, rear-wheel-drive architecture shared with other Chrysler products of the era. This platform provided a solid foundation for the car’s aggressive stance and spacious interior. While the V-6 models offered a more accessible entry point into the Challenger lineup, the year also set the stage for the highly anticipated HEMI V-8 models that would soon follow. The 3.5L V-6 engine in the 2009 model was a naturally aspirated, SOHC engine designed to provide adequate power for a comfortable and spirited driving experience, balancing performance with fuel efficiency.
From a design perspective, the 2009 Challenger was a visual standout. Its retro-inspired exterior featured a long hood, short deck, and a wide, aggressive grille that immediately drew attention. The interior, while modern for its time, focused on a driver-centric layout with comfortable seating and a classic dashboard aesthetic. The vehicle was marketed as a versatile muscle car, capable of daily commuting and weekend track days alike. For the 3.5L model, the driving character was defined by smooth acceleration and a refined ride quality that distinguished it from the more raucous V-8 variants. This made it a popular choice for enthusiasts who wanted the iconic Challenger looks and rear-wheel-drive dynamics without the higher fuel consumption associated with the larger engines. The 2009 Challenger remains a beloved vehicle, celebrated for its bold design and the strong sense of nostalgia it evokes among car lovers.
