Understanding the specific fluid requirements for the 2016 Dodge Charger 6.4L helps prevent premature wear and extends the life of your vehicle’s most expensive components. The engine oil capacity for this model is 7.0 quarts when the AMSOIL Oil Filter is changed, a critical detail to ensure proper lubrication coverage. The torque specification for the oil drain plug is 20 ft/lbs, so care must be taken to avoid over-tightening and damaging the threads during a routine oil change. Beyond the engine, the 8-speed automatic transmission requires a total fill of 9 quarts for the 8HP70 unit, making the use of the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid vital for shifting precision and longevity. The rear differential holds 2.3 pints of lubricant, and selecting the correct viscosity between AMSOIL SEVERE GEAR® 75W-85 and 75W-90 depends on whether the vehicle has a standard or limited-slip differential. Cooling system maintenance is equally important, with a total capacity of 15.2 quarts for the antifreeze mixture.
Engine Oil and Filtration for the 6.4L HEMI
The 6.4-liter HEMI engine is known for its robust performance and distinctive exhaust note, but it also generates significant heat that can break down conventional oils quickly. AMSOIL Signature Series 0W-40 100% Synthetic Motor Oil is formulated to provide 75% more engine protection against horsepower loss and wear compared to industry standards. This synthetic motor oil offers unrivaled protection for up to 25,000 miles or one year, which is particularly beneficial for drivers who push their vehicles or operate in extreme temperatures. The oil maintains its viscosity better than conventional oils, ensuring that the engine stays lubricated during cold starts and hot running conditions alike. When paired with the AMSOIL Oil Filter, which offers extended service life and superior contaminant capacity, the engine receives a level of cleanliness that minimizes wear on bearings, camshafts, and piston rings. The filter allows for lower restriction, keeping engine parts lubricated and helping to reduce engine wear over time. For those who prefer a premium alternative, the WIX Oil Filter provides premium media that offers improvements over original equipment manufacturer-branded filters, ensuring that the high-flow requirements of the HEMI are met with reliable filtration efficiency.
Transmission and Drivetrain Protection
The smooth operation of the 8HP70 automatic transmission in your Charger relies heavily on the properties of the fluid used. Standard transmission fluids can break down under the heavy loads and elevated temperatures associated with spirited driving. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero temperatures. It provides reserve protection during heavy use and abuse, ensuring that the transmission shifts smoothly even under stress. For drivers looking for a reliable OE-specification alternative, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid protects against wear and is a cost-effective option that still delivers high-performance characteristics. Both fluids are engineered to provide excellent protection for the complex hydraulic and mechanical systems within the transmission, preventing sludge buildup and ensuring long-term reliability.
The rear differential is another critical area that requires attention. Depending on the configuration of your vehicle, whether it has a standard rear differential or a limited-slip version, the correct AMSOIL SEVERE GEAR® 75W-85 is essential. For the standard 230RIA rear differential, the AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube is recommended. It contains friction modifiers for limited-slip applications and helps reduce operating temperatures, which extends the life of the gears and bearings. If your Charger features a limited-slip differential requiring GLSB8 friction modifiers, the AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is the optimal choice. This heavier viscosity grade provides the necessary lubrication to prevent gear chatter while offering advanced protection against wear, thermal runaway, and rust. Both gear lubes are designed to control thermal runaway and protect against corrosion, ensuring that your drivetrain operates smoothly and efficiently for the long haul.
Cooling System and Brake Fluid Maintenance
Maintaining the cooling system is crucial for the 6.4L engine, which operates at high temperatures. The system requires 15.2 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant to ensure proper circulation and heat dissipation. It is a unique poly-organic acid (OAT) formulation that allows for use in a wide variety of vehicles while protecting all cooling system metals, gaskets, and hoses. It is compatible with all other antifreeze and coolant colors, making it easy to top off without worrying about mixing issues. For those who prefer a concentrated solution, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended protection up to 150,000 miles or five years. This concentrate requires mixing with distilled or high-quality water and greatly surpasses standards for metallic corrosion and erosion. Both formulations are phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, providing safe and effective cooling protection.
Brake fluid plays a pivotal role in the safety and performance of your Charger. Over time, brake fluid can absorb moisture, leading to a lower boiling point and potential brake fade. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is designed for excellent ABS and traction-control responsiveness. It provides a stable viscosity over a wide temperature range, ensuring consistent braking performance in all conditions. By replacing your brake fluid with this synthetic option, you enhance the safety of your vehicle and ensure that the hydraulic system operates smoothly without the risk of vapor lock or corrosion in the brake lines.
