The 1982 Chrysler Imperial, powered by the robust 5.2L V-8 engine (Engine Code J), is a vehicle that demands precision maintenance to preserve its longevity. Owners of this classic automobile know that proper lubrication is the cornerstone of reliable operation, especially as the vehicle ages. The engine, transmission, and differential all require specific fluid types to function smoothly, particularly given the vehicle’s heavy-duty design heritage. Neglecting fluid changes can lead to accelerated wear, overheating, or difficult shifting, making it essential to use high-performance synthetic fluids designed to withstand the rigors of both modern driving conditions and the demands of a classic powertrain.

Ensuring your 1982 Chrysler Imperial receives the correct fluids is not merely a maintenance task; it is an investment in the vehicle’s future. This specific engine, the 5.2L V-8, was designed with a capacity of 5.0 quarts including the filter change. Using the correct viscosity is critical for proper oil flow, particularly in varying climates. The recommended 10W-30 viscosity grade provides the necessary film strength to protect engine components while ensuring adequate circulation during cold starts. By choosing synthetic options, you enhance the oil’s ability to resist breakdown and oxidation, which is particularly beneficial for a vehicle that may not see daily use but requires peak reliability when driven.
Transmission and Drivetrain Maintenance
The automatic transmission in this model, whether equipped with a 3-speed with lockup or a different variation of the A904 series, requires fluid that can handle the stress of shifting gears smoothly. The total fill capacity can vary depending on the specific transmission configuration, with some requiring up to 8.8 quarts for a total fill. AMSOIL offers synthetic transmission fluids that resist the thermal breakdown that often plagues older automatic transmissions. These fluids maintain their viscosity in extreme heat, which is vital for preventing shudder and ensuring smooth gear engagement. For those with limited-slip differentials, the use of a gear lube containing friction modifiers is essential to prevent the characteristic chattering that can occur when standard lubricants are used in these specialized units.
The rear differential specifications for the 1982 Imperial often call for GL-5 rated lubricants, with capacities ranging from 2.1 to 4.4 pints depending on whether the differential includes a 7.25 gear ring and whether it is a limited-slip variant. AMSOIL SEVERE GEAR® products are engineered to handle these exact specifications. They provide a protective layer that shields gears from wear and rust, even when the vehicle is stored for periods. The 75W-90 and 80W-90 grades offer excellent low-temperature pumpability, ensuring the lubricant reaches all moving parts immediately upon startup, while their high-temperature stability prevents the fluid from thinning out under heavy loads.
Braking and Cooling Systems
Safe operation of any vehicle relies heavily on the braking system. The 1982 Imperial utilizes a hydraulic brake system compatible with DOT 3 fluid specifications. AMSOIL’s synthetic brake fluid meets both DOT 3 and DOT 4 requirements, providing a higher boiling point than conventional fluids. This prevents brake fade during hard stops and ensures consistent pedal feel, even after repeated use. Similarly, the cooling system, which holds approximately 15.3 quarts of coolant, requires protection against corrosion and freezing. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed solution that protects all cooling system metals and rubber components. For those who prefer to mix their own, the concentrated Propylene Glycol antifreeze offers an eco-friendly alternative with extended service intervals, safeguarding the engine against overheating in the summer and freezing in the winter.
Valuable Additives and Fluids for Long-Term Storage
Classic vehicles often spend time in storage, making the use of stabilizers and protectants highly recommended. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog fuel systems. During seasonal storage, AMSOIL Engine Fogging Oil is an excellent addition to protect internal engine components from rust. For the interior and exterior, a range of cleaners and protectants is available. The AMSOIL Engine Degreaser can tackle tough grease and grime on the engine block, while the AMSOIL Heavy-Duty Metal Protector provides a long-lasting, wax-like coating to guard against rust and corrosion on metal surfaces. These products ensure that every aspect of the vehicle remains in pristine condition.
About the Vehicle
The 1982 Chrysler Imperial stands as a testament to American automotive engineering from the early 1980s. Built on the Chrysler LH platform, it was essentially a rebadged version of the Chrysler LeBaron but offered as a flagship model that combined luxury with performance. The 5.2L V-8 engine, often referred to as the “5.2 Magnum” precursor or simply the 318 cubic inch V-8, was a workhorse engine known for its durability and torque. It was capable of delivering substantial power for its era, typically producing around 125 to 145 horsepower depending on specific tuning and emission controls of the model year. This engine was designed to propel the heavy, full-size sedan with relative ease, making it a favorite among owners who valued smooth acceleration and the ability to tow light loads.
Owners of the 1982 Imperial often appreciate the vehicle’s comfortable ride and spacious interior, which featured high-quality materials and a focus on comfort that was characteristic of Chrysler’s full-size lineup at the time. The car was marketed as a luxury vehicle, offering features that were considered premium for the period, including advanced climate control systems and sound insulation. While the design language of the early 80s was distinct, the Imperial managed to retain a timeless elegance that continues to attract collectors today. The 5.2L engine’s robust construction means that with proper maintenance, these vehicles can continue to run reliably for decades. Whether driven occasionally as a cruiser or used regularly, the 1982 Imperial remains a symbol of classic American motoring, representing an era where comfort and power were seamlessly integrated into a single package.
