The 2012 Dodge Charger equipped with the 3.6-liter V6 engine is a powerhouse of performance and engineering. To keep this vehicle running at its peak, using the correct lubricants is essential. Proper fluid selection ensures that internal components are protected against wear, corrosion, and extreme temperatures. Whether you are navigating city traffic or taking a road trip, the right oil and fluids can significantly extend the life of your engine and transmission. The 3.6L engine requires a specific viscosity to maintain proper oil pressure and flow, particularly during cold starts and under heavy load.

When performing maintenance on your 2012 Dodge Charger, it is important to note that the 3.6L engine requires 5.9 quarts of oil when changing the filter. The recommended viscosity for all temperature conditions is 5W-30. For owners who frequently use E85 or M85 fuels, it is crucial to adhere to the OEM-recommended drain intervals unless you plan to conduct regular oil analysis. The drain plug torque specification is 20 ft/lbs, ensuring a secure seal without risking thread damage.
Beyond the engine, the transmission and cooling systems play vital roles in the vehicle’s overall reliability. The 2012 Charger with the 8-speed automatic transmission (8HP45) requires a fluid change to prevent shifting issues and sludge buildup. While a full refill requires 9.5 quarts, regular maintenance intervals ensure the transmission remains fluid and responsive, even during heavy towing or spirited driving in extreme heat.
Essential Cooling and Transmission Fluids
The cooling system for the 3.6L engine holds approximately 10 quarts of fluid. Using a high-quality antifreeze and coolant is non-negotiable for preventing corrosion and maintaining optimal operating temperatures. AMSOIL offers two distinct options for this vehicle. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 solution that is phosphate, nitrate, and silicate-free, providing protection for up to 150,000 miles or five years. For those who prefer a concentrated formula, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers superior thermal stability and extended protection up to 150,000 miles, requiring mixing with distilled water.
For the transmission, the 8HP45 gearbox benefits greatly from synthetic fluids that resist oxidation and shear. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand the rigors of heavy towing and elevated temperatures while maintaining fluidity in sub-zero conditions. If you prefer a more budget-friendly option that still offers synthetic benefits, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides excellent wear protection and helps promote smooth, shudder-free shifts.
Differential and Gear Lubrication
The rear differential on this vehicle typically uses a specific viscosity depending on the gear ratio. For the 175mm FIA rear differential, the capacity is 1.3 pints, while the 200mm and 215mm rear differentials hold 2.3 and 2.5 pints respectively. The front standard differential requires 1.3 pints as well. For these limited-slip and standard applications, AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is an excellent choice, offering advanced protection against wear and rust while controlling thermal runaway. For axles requiring a thicker fluid, AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube provides the necessary load-carrying capacity and friction modifiers for limited-slip differentials. Other viscosity options like AMSOIL SEVERE GEAR® 75W-110 and AMSOIL SEVERE GEAR® 80W-90 are available for specific applications or transfer cases, ensuring that all moving gears receive the appropriate lubrication.
Other Critical Fluids and Maintenance
Brake safety is paramount, especially for a vehicle with the performance capabilities of the Charger. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent responsiveness for ABS and traction control systems, maintaining stable viscosity across a wide temperature range. For power steering systems equipped with Electric Power Steering (EPS), the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is recommended to reduce friction, keep seals soft, and prevent leaks over the long term.
To keep your fuel system clean and efficient, consider using a fuel additive like AMSOIL P.i.® Performance Improver Gasoline Additive. This powerful additive helps restore lost horsepower, cleans fuel injectors, and prevents carbon buildup, ensuring that your 3.6L engine runs as efficiently as possible. For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, protecting against varnish and gum buildup caused by ethanol-blended fuels.
Vehicle Background and Performance Context
The 2012 Dodge Charger represents a significant milestone in the legacy of the Charger nameplate. Reintroduced in 2005 as a four-door sedan, this generation combined the classic muscle car aesthetic with the practicality of a family hauler. The 3.6-liter Pentastar V6 engine was introduced as a highly efficient and reliable powerplant that offered a compelling balance of performance and fuel economy compared to the larger Hemi V8 options available in the lineup.
Owners of the 2012 model year often appreciate the vehicle’s commanding road presence and refined interior. The design features a bold grille, sleek lines, and a cabin that prioritizes comfort, making it a popular choice for both daily commuting and road trips. The rear-wheel-drive platform provides a engaging driving dynamic, while the optional All-Wheel Drive system offers added confidence in inclement weather. With its spacious interior and generous trunk capacity, the Charger serves as a versatile sedan that does not compromise on style.
The 3.6L engine, known for its smooth power delivery and durability, became a staple in the Chrysler lineup. While it produces less peak horsepower than the Hemi V8s, it offers strong mid-range torque and significantly better fuel efficiency. This engine is capable of powering the Charger up to highway speeds with ease, though enthusiasts often tune it to unlock further potential. The vehicle’s reputation for reliability, when maintained with proper fluids, makes it a durable choice for drivers who demand performance without sacrificing practicality. Whether you are navigating suburban streets or tackling longer journeys, the 2012 Charger is designed to deliver a smooth and confident ride.
By selecting the appropriate AMSOIL synthetic lubricants, you are investing in the long-term health of your vehicle. Regular fluid changes, including engine oil, transmission fluid, and coolant, ensure that every component operates within its optimal parameters. The synergy between high-quality fluids and compatible filters creates a protective barrier against the wear and tear of everyday driving. This approach not only extends the service life of your Dodge Charger but also helps maintain its resale value and performance characteristics for years to come.
