Engine Oil Specifications and Service Intervals
The 1987 Dodge Aries 2.2L engine requires a specific amount of fluid to ensure proper lubrication of the crankshaft, camshaft, and valve train. With a filter installed, the capacity for the engine oil is 4.0 quarts. It is crucial to adhere to the torque specification of 20 ft/lbs for the oil drain plug to prevent damage to the drain plug or the oil pan during service. After refilling, the oil level should always be checked to ensure it falls within the safe operating range on the dipstick.
AMSOIL Signature Series 5W-30 is the top recommendation for this engine, providing unparalleled protection against horsepower loss and wear. It is trusted by professional engine builders and offers guaranteed protection for up to 25,000 miles or one year. For those seeking a robust option that balances performance and cost, AMSOIL Extended-Life 5W-30 provides 20,000 miles of protection with 37% more cleaning power than the OE oil. AMSOIL OE 5W-30 is another excellent choice that fights sludge and deposits effectively, while AMSOIL 5W-30 High-Mileage is ideal for vehicles that have surpassed 75,000 miles, reducing sludge by 67% and boosting the detergent package to keep older engines running better.
Transmission and Cooling System Maintenance
Fluid exchange is not limited to the engine. The transmission plays a vital role in the drivability of the Aries, and using the correct fluid can prevent costly failures. For models equipped with the 3-speed A470(31TH) or A413(31TH) automatic transmissions, the total fill capacity is 8.9 quarts, with an initial fill of 4 quarts. AMSOIL Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid is designed to withstand the rigors of heavy towing and high temperatures, remaining fluid even in sub-zero conditions. AMSOIL OE Multi-Vehicle variant offers excellent cold-weather performance and promotes smooth, shudder-free shifts.
The cooling system is equally critical for maintaining engine health. The 1987 Aries holds approximately 9 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. It is an ethylene glycol 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses. It is phosphate, nitrate, nitrite, silicate, borate, and amine-free, making it compatible with all other antifreeze colors. For those who prefer a concentrated product that can be mixed with distilled water for ultimate control, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers protection up to 150,000 miles or 5 years.
Brake, Steering, and Fuel Care
Hydraulic brake fluid performance is paramount for safety. The 1987 Dodge Aries recommends a DOT 3 fluid meeting MS-4574 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent ABS and traction-control responsiveness, providing a stable viscosity over a wide temperature range. This synthetic fluid is superior to conventional options, offering better resistance to moisture absorption and boiling points under heavy braking.

Vehicle Background and Historical Context
The 1987 Dodge Aries stands as a significant chapter in American automotive history, representing the culmination of Chrysler’s “K-Car” platform that revitalized the company in the early 1980s. Built on the Chrysler K-platform, the Aries was a compact sedan designed to compete with the Japanese imports that were dominating the market at the time. The vehicle’s primary appeal lay in its fuel efficiency, front-wheel-drive traction, and surprisingly spacious interior, which offered a level of roominess not typically found in smaller sedans of that era.
Powered by the reliable 2.2L inline-four engine, the Aries was engineered for durability and economical operation. The 2.2L engine code [D] D, as seen in this specific vehicle, is part of the renowned Chrysler “S” engine family, known for its robust construction and versatility. While often associated with moderate acceleration and a focus on practicality, the 2.2L variant provided sufficient power for daily commuting and family duties. The Aries shared its underpinnings with the Dodge Omni, creating a versatile platform that saw service in various roles, from personal transportation to fleet vehicles.
Owners of the 1987 Dodge Aries often appreciate its straightforward mechanical design. The front-wheel-drive layout contributed to better traction in adverse weather conditions, making it a reliable choice in the snowy climates of the North American Midwest. The interior design prioritized utility, with a dashboard layout focused on driver ergonomics and easy access to controls. Over the years, the Aries has earned a reputation for being a “workhorse” vehicle, capable of logging high mileage with proper maintenance.
However, like any vehicle of this vintage, the Aries can face specific challenges as it ages. One common issue with the 2.2L engine is the tendency for sludge buildup, particularly if conventional oils are used or if service intervals are extended beyond recommended limits. The use of high-quality AMSOIL Signature Series can mitigate this risk significantly, as the advanced detergent packages effectively prevent the accumulation of carbon and sludge deposits. Another prevalent problem involves the cooling system, where aging gaskets and hoses can lead to leaks or overheating. AMSOIL’s antifreeze and coolant products are designed to protect these aging components, ensuring the cooling system remains effective and preventing corrosion that can lead to costly repairs.
Brake system degradation is also a concern for older vehicles, as rubber seals can harden over time, leading to fluid contamination and reduced braking performance. Switching to synthetic brake fluid helps maintain a stable viscosity and prevents the moisture absorption that plagues conventional DOT 3 fluids, thereby preserving the integrity of the ABS and traction control systems. Finally, the power steering system in these older models can suffer from seal hardening, resulting in leaks or noisy operation. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid provides the necessary lubrication to keep seals soft and pliable, ensuring smooth and quiet steering for years to come.
Maintaining the 1987 Dodge Aries is a labor of love for many enthusiasts who value its retro design and practical engineering. By selecting the right lubricants and fluids, owners can preserve the vehicle’s original character while ensuring it remains safe and reliable for modern roads. Whether for weekend drives or daily commuting, the correct maintenance regimen ensures that this classic K-Car continues to perform with the efficiency and dependability it was originally designed for.
