Engine Oil and Filtration
The heart of your 1997 Chrysler Concorde is the 3.5L 6-cylinder engine, which is designed to operate optimally with specific synthetic lubricants. For this application, SAE 10W-30 is the preferred viscosity when operating in temperatures above -18°C. If you reside in a climate where temperatures drop below 0°C, a 5W-30 viscosity is recommended. The engine requires a total capacity of 5.5 quarts, including a filter replacement. Always ensure you check the oil level after refilling and torque the drain plug to the specified 25 ft/lbs.
AMSOIL offers four distinct motor oil formulations tailored to different mileage and driving styles. The AMSOIL Signature Series 10W-30 100% Synthetic Motor Oil provides the highest level of protection, capable of lasting up to 25,000 miles or one year, making it ideal for severe driving conditions or drivers who extend oil change intervals. It offers 75% more engine protection against wear compared to industry standards. For those seeking a balance between performance and extended change intervals, the AMSOIL Extended-Life 10W-30 100% Synthetic Motor Oil guarantees 20,000 miles of protection and features enhanced cleaning power to keep the engine running smoothly.
If you are looking for an oil that outperforms conventional oils while maintaining cost-effectiveness, the AMSOIL OE 10W-30 100% Synthetic Motor Oil is an excellent choice. It is designed to fight sludge and deposits effectively. For Conordes that have surpassed 75,000 miles, the AMSOIL 10W-30 100% Synthetic High-Mileage Motor Oil features a unique chemistry with boosted detergents and dispersants, reduced sludge by 67%, and enhanced anti-wear additives to keep older engines running better.
Filtration is equally critical. The AMSOIL Oil Filter (EAO42-EA) is engineered for this vehicle, providing 99% filtration efficiency at 20 microns. It features greater capacity for contaminants compared to competing filters and allows for lower restriction, which keeps engine parts properly lubricated. For those who prefer a well-known aftermarket brand, the WIX Oil Filter (51085-EA) offers premium media with improvements over OEM-branded filters.
Transmission and Differential Fluids
The 1997 Concorde is equipped with a 42LE 4-speed automatic transmission. Proper fluid maintenance is vital to prevent costly transmission problems. The total fill capacity for the 42LE transmission is 9.9 quarts, with an initial fill of 4.5 quarts. Using a high-quality synthetic fluid can help the transmission withstand heavy towing, elevated temperatures, and challenging terrain.
The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is formulated to remain fluid in sub-zero temperatures while providing reserve protection during heavy use. It is designed to resist harmful sludge and offers excellent cold-weather performance. Alternatively, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid promotes smooth, shudder-free shifts and guards against leaks, ensuring your transmission shifts remain crisp for years to come.
For the front differential, which requires a GL-5 lubricant, AMSOIL offers three specialized gear lubes. The AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is recommended for the front differential, which holds 1.9 pints. This lube contains friction modifiers for limited-slip applications and helps control thermal runaway. For heavier loads or different operating conditions, the AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube or AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube provide advanced protection against wear, rust, and corrosion, extending the life of seals and equipment.
Cooling System and Brake Fluid
Keeping your engine at the optimal temperature is crucial for the longevity of the Concorde’s V6. The cooling system requires a significant amount of fluid, with a total capacity of 12.2 quarts. For a reliable, pre-mixed solution, the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles. If you prefer to mix your own, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that offers superior corrosion protection in both passenger cars and heavy-duty applications.
Brake safety should never be compromised. The 1997 Concorde uses a DOT 3 hydraulic brake fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent responsiveness for ABS and traction-control systems. Its stable viscosity over a wide temperature range provides consistent braking performance, whether you are driving in the heat of summer or the cold of winter.
Additional Maintenance and Care
To round out your vehicle’s maintenance, the power steering system benefits from the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid. This fluid reduces friction, keeps seals soft to prevent leaks, and resists heat for long fluid life. It is formulated for quiet operation and offers strong anti-wear protection.
For owners who store their vehicles seasonally, AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, protecting against varnish and ethanol corrosion. During long periods of inactivity, AMSOIL Engine Fogging Oil provides a rust preventive coating on internal components. To maintain peak performance, the AMSOIL P.i.® Performance Improver restores GDI fuel injectors to 100% flow rate and can restore up to 14% horsepower. Finally, for general cleaning and protection, a wide range of products including degreasers, waxes, and metal protectors are available to keep your Concorde looking and running its best.
About the 1997 Chrysler Concorde
The 1997 Chrysler Concorde represents a significant chapter in American automotive history, standing as a flagship sedan that blended executive comfort with practical utility. Introduced as a replacement for the Chrysler New Yorker, the Concorde was built on the advanced LH platform, which was renowned for its lightweight aluminum suspension components and unibody construction. This engineering approach gave the vehicle a distinct advantage in terms of handling and fuel efficiency compared to many of its rear-wheel-drive contemporaries. Powered by Chrysler’s legendary 3.5L ES (Electric Suspension) V6 engine, the 1997 model offered a robust balance of power and smoothness, making it a popular choice for families and long-distance commuters alike.
Owners of the 1997 Concorde often appreciate its spacious interior, which was designed to rival European luxury sedans of the era. The car’s smooth ride quality, attributed to the front-wheel-drive layout and sophisticated suspension tuning, provided a quiet cabin environment that was highly sought after in the mid-size sedan segment. While the vehicle may not possess the raw performance of a sports sedan, its reputation for reliability and durability, when properly maintained with high-quality lubricants, has allowed many units to remain on the road well beyond their original design expectations. The Concorde’s market position during the late 90s was that of a value-oriented luxury vehicle, offering premium features and a refined driving character without the luxury price tag of imported rivals.
The 3.5L V6 engine found in the Concorde is a workhorse, known for its durability but also for its specific lubrication needs. The engine’s timing chain and hydraulic lifters rely heavily on consistent oil pressure and film strength, which is why using a high-quality synthetic motor oil is often recommended over conventional blends. Over the years, the Concorde has developed a cult following among car enthusiasts who value its unique design language and driving dynamics. As these vehicles age, the importance of using the correct fluids—such as the specific 10W-30 synthetic oils and compatible transmission fluids discussed in this guide—becomes even more critical to preserving their condition and ensuring they continue to provide the smooth, reliable service that defined their era.
