The 6.2L HEMI V8 in your Charger is a powerhouse, but that power comes with demands that conventional mineral oils cannot fully meet. The Signature Series 0W-40 Motor Oil is formulated to handle the high thermal loads of this engine while maintaining optimal flow during cold starts. With a capacity of 7.0 quarts including the filter, ensuring you have the right oil volume and a high-quality filter to match is critical. The AMSOIL Oil Filter is designed with greater capacity for small, wear-causing contaminants than competing filters, helping to extend the life of your engine and supporting the extended oil change intervals that synthetic oils allow. If you prefer the reliability of a trusted aftermarket brand, the WIX Oil Filter offers premium media improvements over original equipment manufacturer branded filters, providing a robust alternative for your maintenance schedule.
Beyond the engine, the 2018 Charger’s cooling system plays a vital role in managing the heat generated by the HEMI. The engine coolant capacity is approximately 15.2 quarts, with an additional 5 quarts required for the intercooler. For these systems, AMSOIL offers both a pre-mixed ethylene glycol formulation, the Passenger Car & Light Truck Antifreeze & Coolant, and a concentrated propylene glycol option, the Propylene Glycol Antifreeze and Engine Coolant. Both formulations are designed to exceed original equipment manufacturer requirements, protecting all cooling system metals, gaskets, and hoses from corrosion.
Transmission health is another critical area for the 2018 Charger, which utilizes the 8HP90 8-speed automatic transmission. With a total fill capacity of 9.2 quarts, using a fluid designed for severe service is essential. The Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and elevated temperatures while remaining fluid in sub-zero conditions. For drivers looking for a robust option that resists harmful sludge and promotes smooth, shudder-free shifts, the AMSOIL OE Fuel-Efficient Automatic Transmission Fluid is an excellent choice.
The rear differential of your Charger, specifically the limited-slip differential, requires specific attention. The 230RIA GLSB8 application calls for a robust lubricant that can handle high loads and prevent thermal runaway. AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube contains friction modifiers designed for limited-slip applications, ensuring that you maintain traction and control while extending the life of the gears and bearings.
Finally, the braking system and fuel system contribute significantly to the overall performance and safety of your Charger. The recommended AMSOIL DOT 3 and DOT 4 Brake Fluid provides excellent ABS and traction-control responsiveness. This fluid maintains a stable viscosity over a wide temperature range, ensuring consistent brake pedal feel. Additionally, the 6.2L HEMI engine benefits greatly from the use of AMSOIL P.i.® Performance Improver Gasoline Additive. This gasoline additive works to restore up to 14% of lost horsepower by cleaning GDI fuel injectors, ensuring that the engine receives the precise amount of fuel it needs for optimal combustion and efficiency.
About the Vehicle
The 2018 Dodge Charger represents the pinnacle of modern American muscle sedans. Built on the LX platform, which also underpinned the legendary Charger and Challenger of the past, the 2018 model benefits from significant updates that blend classic muscle car aesthetics with contemporary safety and technology. The Charger is distinct in the automotive world for offering a four-door sedan that can compete with sports cars, a design philosophy that has resonated with a wide range of drivers. The model is available in a variety of trims, from the efficient base models to the high-performance SRT Hellcat and Scat Pack variants.
The 6.2L V8 HEMI engine, known internally as the ESD, is the heart of the higher-performance models like the SRT Hellcat and the R/T Scat Pack. This supercharged or naturally aspirated (depending on the specific trim level, though the ESD code specifically denotes the supercharged version) engine delivers an immense amount of horsepower and torque. The supercharged variant, in particular, pushes the boundaries of what a production sedan can achieve, often producing over 700 horsepower. This level of power requires a chassis and drivetrain that can handle the stress, which is why proper lubrication is so critical. The suspension and steering components are tuned to provide a comfortable ride while maintaining the agility required to handle the sudden bursts of speed.
Owners of the 2018 Dodge Charger often cite the combination of practicality and raw power as the primary reason for choosing this vehicle. It is a car that can transport a family or a group of friends in comfort while also providing an adrenaline rush on the weekend. The interior is typically well-appointed with high-quality materials, modern infotainment systems, and advanced safety features. However, the high-performance nature of the vehicle means that the engine and transmission are subjected to extreme thermal and mechanical stress. The HEMI engine, with its crossfire induction system and advanced variable valve timing, relies on stable oil viscosity to maintain the precise tolerances required for peak performance.
Despite its reliability, the 2018 Charger is not without its common issues, many of which can be mitigated or managed through the use of high-quality synthetic lubricants. One common problem reported by owners is carbon buildup on the intake valves, particularly in the Direct Injection (GDI) engines. Over time, this can lead to rough idling, loss of power, and reduced fuel economy. The use of a fuel additive like AMSOIL P.i. Performance Improver can help prevent this buildup and restore lost performance, making it a valuable addition to the maintenance regimen of any HEMI owner.
Another area of concern for high-mileage Chargers is engine wear related to oil consumption. The high-output nature of the HEMI engine can sometimes lead to increased oil consumption over time, especially if the oil breaks down under heat. Synthetic oils like AMSOIL Signature Series 0W-40 are specifically formulated to resist thermal breakdown and maintain their protective properties longer than conventional oils, which can help reduce the frequency of top-offs and extend the life of the engine components. Additionally, the transmission fluid in these vehicles can degrade under the stress of hard driving, leading to shuddering or delayed shifts. Using a synthetic transmission fluid that maintains its viscosity and protects against wear can prevent these issues and ensure smooth power delivery from the engine to the wheels.
Furthermore, the braking systems on performance models like the SRT are designed to handle high speeds and repeated hard stops. This places a significant thermal load on the brake fluid, which can absorb moisture over time and lower its boiling point. A synthetic brake fluid with a higher boiling point and better stability ensures that the brakes remain effective even after repeated heavy use, providing a critical safety margin for the driver. By addressing these common areas of wear and potential failure with the right lubricants, owners can ensure that their 2018 Dodge Charger continues to perform at the level it was designed for, year after year.
Ultimately, the 2018 Dodge Charger is a vehicle that demands the best from its fluids and lubricants. Whether you are driving in the harsh winters of the north or the scorching summers of the south, having the right AMSOIL products in your car ensures that your vehicle is protected against the elements and the road ahead. The comprehensive protection offered by AMSOIL synthetic oils, filters, and fluids provides peace of mind, allowing you to enjoy the full potential of your Charger without worrying about premature wear or unexpected breakdowns.
