The 2018 Dodge Challenger equipped with the 6.2L HEMI V8 (Engine Code [9] ESD 9) is a powerhouse designed for performance and aggressive driving. To maintain its integrity and ensure long-lasting protection, using the correct synthetic lubricants is essential. This engine requires specific viscosity grades and capacity volumes to handle the high stress of its supercharged or naturally aspirated configurations. Proper fluid selection goes beyond just the engine oil; it extends to the transmission, cooling system, and differential, ensuring every component operates efficiently under varying road conditions.

Ensuring your Challenger receives the correct lubrication is critical for sustaining its high-performance character. The 6.2L V8 engine generates significant heat and torque, placing immense stress on internal components. Using a synthetic oil like AMSOIL Signature Series 0W-40 ensures the engine is protected against the extreme conditions often found in muscle cars, such as rapid acceleration and high-speed cruising. The 0W-40 viscosity grade offers superior film strength compared to standard multi-grade oils, minimizing friction and maximizing fuel economy while still providing the necessary thickness to protect bearings and camshafts at high temperatures.
When performing an oil change, it is important to account for the total system capacity. For the 6.2L engine with engine code [9] ESD 9, the total oil capacity is 7.0 quarts when the filter is replaced. The oil drain plug torque specification is 20 ft/lbs, a detail that should be followed to prevent stripping threads or causing leaks. Complementing the high-performance oil with the AMSOIL Oil Filter ensures that contaminants are removed efficiently. This filter offers extended service life, allowing you to follow extended oil change intervals with confidence, knowing that the engine remains clean and protected.
While the engine is the heart of the vehicle, the transmission plays a crucial role in delivering power to the wheels. The 2018 Challenger often comes equipped with an 8-speed automatic transmission (model 8HP90). For these models, the total fill capacity is approximately 9.2 quarts. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to handle the demanding nature of this gearbox. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use, such as towing or spirited driving. If you prefer an OE-specified fluid, the AMSOIL OE Fuel-Efficient ATF is also an excellent choice that resists harmful sludge and promotes smooth shifts.
The cooling system is another critical area that requires attention. With an engine intercooler requiring 4.4 quarts and the engine itself needing 15.2 quarts, maintaining the correct antifreeze-to-water ratio is vital. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an Ethylene Glycol 50/50 pre-mix that is compatible with all cooling system metals. For those who prefer a concentrated solution to mix themselves, the AMSOIL Propylene Glycol Antifreeze offers a robust alternative with a service life of up to 5 years or 150,000 miles in passenger cars. Both options are phosphate-free and nitrite-free, ensuring the longevity of the cooling system components.
For those who modify their vehicles or drive in severe conditions, the differential and brake systems also benefit from premium lubricants. The rear limited-slip differential requires a AMSOIL SEVERE GEAR 75W-90 that can handle the specific friction modifiers needed for its operation. This fluid provides the necessary protection, helping to reduce operating temperatures and extending the life of the differential gears and seals. Similarly, the braking system requires a fluid that will not boil under heavy use. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures consistent pedal feel and prevents corrosion within the brake lines and calipers, which is essential for the safety and responsiveness of this high-performance machine.
Vehicle Background
The 2018 Dodge Challenger is a modern classic that pays homage to the legendary muscle cars of the late 1960s while offering the technology and safety features expected of a 21st-century vehicle. Produced by Chrysler LLC, the Challenger has become a symbol of American muscle, combining retro styling cues with aggressive performance capabilities. The model line is part of the Dodge brand’s effort to bring back the “muscle car” segment, which had been largely absent from the market for several years. The Challenger distinguishes itself with a wide stance, bold grille, and distinctive headlights that give it an unmistakable road presence.
Under the hood, the 2018 model year offers a range of engines, from the efficient Pentastar V6 to the legendary HEMI V8s, including the 5.7L, the supercharged 6.2L, and the supercharged 6.4L variants. The specific vehicle covered here, the 6.2L engine, is a powerhouse that delivers substantial horsepower and torque, making it a favorite among enthusiasts who seek acceleration and a raw driving experience. Whether equipped with the 6.2L in a naturally aspirated form or the supercharged Hellcat configuration, the Challenger is designed to be a driver’s car, offering sharp handling and a connected feel that appeals to sports car lovers. The platform is based on the Chrysler LC platform, which shares DNA with the Charger sedan but is tuned for a more aggressive stance and driving dynamics.
Owners of the 2018 Dodge Challenger often cite its blend of comfort and performance as a primary reason for ownership. The interior is spacious, capable of seating five passengers comfortably, which is a rarity in the muscle car segment. The driving experience is defined by the rumble of the HEMI V8 and the rapid response of the powertrain. However, the high-output nature of these engines and the frequent spirited driving that owners enjoy can place significant stress on the vehicle’s components. The engine operates at high temperatures and pressures, which can lead to oil breakdown if standard mineral oils are used. Proper lubrication with synthetic fluids helps mitigate these issues, ensuring that the engine remains cool and components stay free from premature wear.
Common issues faced by Challenger owners that can be addressed through proper lubrication include sludge buildup in the engine, transmission shift shudder, and overheating in severe conditions. Using high-quality synthetic motor oil helps prevent sludge and deposit formation, which can be a concern in engines that are driven hard. For the transmission, maintaining the correct fluid helps prevent the shudder issues that can occur in some automatic transmissions over time, ensuring smooth gear changes. Additionally, the cooling system can struggle to manage the heat generated by the powerful V8 engines during track days or heavy towing. High-performance antifreeze and gear lubes help manage these thermal loads effectively, keeping the vehicle running at optimal temperatures. By investing in the right AMSOIL products, owners can preserve the value and performance of their Challenger for years to come.
