Choosing the correct viscosity is the first step in protecting your 2016 Challenger. The 3.6L engine operates best with 5W-20 motor oil. This viscosity grade ensures that critical components receive immediate lubrication during cold starts while maintaining the proper film thickness at operating temperatures. The engine requires 5.9 quarts for a standard oil change, including the filter replacement. After refilling, it is crucial to check the oil level and torque the drain plug to 20 ft-lbs to prevent leaks. If you are running E85 or M85 fuels, extended oil drain intervals should only be pursued through rigorous oil analysis, as these alternative fuels can impact oil degradation rates.
Engine Oil: Balancing Performance and Longevity
For owners who demand the absolute maximum protection available, AMSOIL Signature Series stands as the benchmark. This full synthetic motor oil is engineered to withstand extreme thermal breakdown and shear, which are common stressors in muscle cars that see both spirited driving and highway cruising. The formulation includes advanced detergents that fight sludge and deposits, ensuring the internal passages of the engine remain clear. With a guaranteed 25,000-mile or one-year change interval, Signature Series reduces the frequency of maintenance while extending engine life. Its 75% higher resistance to horsepower loss helps maintain the punchy acceleration that the Challenger is known for.
However, not every driver requires the longest possible interval, and budget-conscious owners will find value in the Extended-Life or OE options. The Extended-Life variant offers a robust cleaning package that helps remove existing carbon and varnish, making it an excellent choice for keeping the 3.6L Pentastar engine running smoothly as it accumulates miles. For those who prefer to match the original equipment specifications closely without compromising on synthetic quality, the OE Motor Oil provides a reliable baseline. It is formulated to meet GM dexos1 Gen 2 specifications, ensuring compatibility with modern engine designs and turbocharger protection.
High-Mileage Solutions
As your Challenger ages beyond 75,000 miles, the engine may develop minor seals that are prone to weeping or consumption. The AMSOIL 5W-20 High-Mileage Motor Oil addresses these specific issues with a unique chemistry. It features a boosted detergent and dispersant package to clean internal components and enhanced anti-wear additives to reduce friction. The formula also reduces sludge formation by 67% in comparative testing, which helps revive the performance of older engines. This fluid is ideal for vehicles where the engine is showing signs of wear or where you want to prevent future issues before they start.
Filtration Matters
Even the best motor oil will lose its effectiveness if contaminants are not removed from the system. The AMSOIL Oil Filter EA15K19 is engineered to provide superior filtration compared to many competitors. It captures 99% of particles at 20 microns, which is small enough to remove the vast majority of wear-causing contaminants before they can damage bearings and cylinder walls. The filter’s synthetic media allows for lower restriction, meaning the oil pump does not have to work as hard to circulate oil, ensuring that all parts are lubricated even under high pressure. For those who prefer a well-known aftermarket brand, the WIX Oil Filter WL10010 is also a compatible and high-quality option.
Transmission and Drivetrain Lubrication
The automatic transmission in the 2016 Dodge Challenger, specifically the 845RE 8-speed unit, requires a fluid that can handle the complex shifting patterns and torque loads of the V6 engine. Using a high-quality synthetic transmission fluid is vital to prevent the sludge and temperature-related problems that can lead to costly repairs. The AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is designed to remain fluid even in sub-zero temperatures, ensuring smooth shifts in all weather conditions. It withstands the rigors of heavy towing and elevated temperatures, providing reserve protection during abuse.
For the rear differential, synthetic oil is a requirement. The differential, identified by the 195RIA code, requires a 75W-85 gear lube with a capacity of 1.5 pints. The AMSOIL SEVERE GEAR® 75W-85 provides advanced protection against wear and rust while helping to control thermal runaway. If your Challenger is equipped with a limited-slip differential, this lube contains friction modifiers specifically designed to improve the operation of the clutch packs in these units, ensuring consistent performance and reducing the “chatter” that can occur with standard gear oils.
Cooling and Brake Systems
Proper cooling is essential for any performance vehicle, especially one with a powerful V6 that can generate significant heat. The cooling system holds 11.1 quarts of fluid. You have two excellent options for coolant. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that is ready to use and offers protection for 150,000 miles or five years. For those who prefer to mix their own or need a concentrated solution for heavy-duty use, the AMSOIL Propylene Glycol Antifreeze is a versatile choice that offers protection up to 150,000 miles in passenger cars and up to one million miles in heavy-duty applications. Both formulations are free from phosphates, silicates, and borates, which helps protect the aluminum components found in modern cooling systems.
Brake safety is non-negotiable. The Challenger’s hydraulic brake system is designed for a DOT 3 fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid exceeds standard requirements, offering a stable viscosity over a wide temperature range. This ensures that the brakes respond quickly and consistently, providing excellent ABS and traction-control responsiveness. Synthetic brake fluids also have a higher boiling point than conventional fluids, reducing the risk of vapor lock during repeated hard stops.
About the Vehicle
The 2016 Dodge Challenger remains one of the most recognizable names in the American automotive landscape, serving as a modern homage to the iconic muscle cars of the 1970s. Designed for enthusiasts who value a blend of retro styling and contemporary performance, the Challenger offers a spacious two-door coupe platform that delivers a comfortable ride without sacrificing power. The 3.6L V6 engine, known as the Pentastar, serves as the standard powerplant for many of these models, providing a reliable balance of efficiency and power that makes the car accessible for daily driving while still delivering respectable acceleration.
This particular generation of the Challenger, launched with the return of the model in 2008, quickly gained a reputation for offering exceptional value in the muscle car segment. Owners appreciate the aggressive exterior design, the spacious interior with premium options, and the robust chassis that handles well on both the street and the track. The 3.6L engine is celebrated for its smooth operation and relative fuel economy compared to the larger V8 and Hellcat variants, making it a popular choice for those who want muscle car styling without the premium cost of high-displacement engines. While it does not produce the raw horsepower of the supercharged models, it remains a capable performer that offers a fun and engaging driving experience for a wide range of drivers.
