The 2009 Dodge Charger equipped with the 3.5L V6 engine is a robust vehicle known for its smooth acceleration and comfortable highway cruising. However, keeping this V6 running smoothly requires more than just a standard oil change at the recommended intervals. The specific demands of this engine, combined with the varying climate conditions across the country, necessitate high-performance lubricants that can withstand extreme temperatures and extended service intervals without compromising engine integrity. Using the correct viscosity and formulation ensures that internal components remain protected against wear, reducing the risk of costly repairs and maintaining the vehicle’s performance over its lifespan.

Maintaining the cooling system is equally critical for the longevity of the 3.5L engine, which operates within tight thermal tolerances. For the 2009 Dodge Charger, AMSOIL Passenger Car & Light Truck Antifreeze & Coolant provides a ready-to-use ethylene glycol 50/50 pre-mix that protects all cooling system metals, gaskets, and hoses. It is designed to last up to 150,000 miles or five years. Alternatively, for those who prefer a concentrated option that requires mixing with distilled water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers exceptional corrosion protection that greatly surpasses industry standards for metallic erosion. Both options are free of phosphates, nitrates, and other additives that can harm certain cooling system components over time.
Transmission and Drivetrain Lubrication
The automatic transmission in the 2009 Dodge Charger, whether it is the 42RLE or the 5-speed NAG1, benefits significantly from synthetic fluid that can handle the rigors of stop-and-go traffic and towing. For the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid, users gain a fluid that remains stable in sub-zero temperatures and resists thermal breakdown during heavy loads. It is engineered to prevent shudder and provides reserve protection during abusive use. For those looking for a reliable OE-style synthetic, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an excellent choice. It guards against leaks, resists harmful sludge, and promotes smooth, shudder-free shifts. This fluid is compatible with the transmission fluid requirements for both the 42RLE and NAG1 transmissions found in this model.
In addition to the transmission, the differential and transfer case in the all-wheel-drive variants of the Charger require specific gear lubricants. For the front differential, which is a 175mm FIA unit, the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube provides advanced protection against wear and controls thermal runaway. For the rear differential, depending on the specific gear set size (198mm, 210mm, or 215mm), the AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube is recommended. This heavier viscosity ensures proper lubrication under heavy load conditions typical of a performance sedan. The AMSOIL 75W-90 Long Life 100% Synthetic Gear Lube is another option, offering extended service life and improved efficiency, making it a viable choice for drivers seeking lower maintenance frequency. The SEVERE GEAR® line contains friction modifiers specifically designed for limited-slip applications, ensuring the differential operates quietly and efficiently.
Brake Fluid and Seasonal Maintenance
Braking performance is a safety priority, and the 2009 Dodge Charger’s ABS system requires fluid that maintains stability under high temperatures. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid delivers excellent responsiveness for both traction control and braking. Its stable viscosity over a wide temperature range ensures consistent pedal feel and prevents the spongy brake pedal often associated with fluid boiling. For vehicle owners who may store their Charger during the off-season or for those who want to ensure peak fuel performance, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and ethanol corrosion. Additionally, the AMSOIL P.i.® Performance Improver Gasoline Additive is highly recommended for restoring fuel injectors to 100% flow rate and improving overall fuel economy.
Vacuum Background
- WIX Air Filter – Offers premium filtration media to ensure the 3.5L V6 receives clean air for optimal combustion and performance.
- WIX Cabin Air Filter – Improves interior air quality by trapping dust, pollen, and other particulates, enhancing comfort for passengers.
About the 2009 Dodge Charger
The 2009 Dodge Charger represents a significant era in American muscle sedan history. Part of the second generation of the Charger, which debuted in 2006 on the LD platform shared with the Chrysler 300 and Dodge Magnum, this model year brought refined styling and improved handling dynamics to a vehicle that had already gained a cult following. The 3.5-liter V6 engine, a staple of the Chrysler LA and ER engine families, is known for its reliability and smooth power delivery rather than aggressive high-revving characteristics. It produces a healthy amount of torque, making it an excellent choice for daily driving, highway commuting, and even light towing, which explains why it is a popular choice for families and commuters who need a spacious, comfortable sedan without the complexity of a larger V8.
Visually, the 2009 model continued the bold, wide stance that defined the Charger’s return to the market. The design language was muscular and distinct, setting it apart from more conservative competitors. Under the hood, the 3.5L engine, while naturally aspirated, was paired with a smooth-shifting automatic transmission that prioritized comfort and efficiency. The vehicle’s popularity stems from its blend of practicality—four doors and a large trunk—with a sporty presence. Many owners appreciate the ease of maintenance on the 3.5L platform, as it is one of the more serviceable engines in the lineup, with accessible components that simplify routine fluid changes and filter replacements. Whether used as a primary family vehicle or a reliable daily driver, the 2009 Charger remains a capable and distinctive automobile that rewards proper maintenance with long-term durability.
