The lubrication needs of the 1985 Chrysler Laser 2.2L E-code turbo are distinct because of the forced induction system. Turbochargers spin at incredibly high speeds, generating intense heat that can break down conventional oils rapidly. The recommended AMSOIL European Motor Oils, both the FS and MS formulations, are designed with precise blends of synthetic base oils and premium additives to handle these extreme conditions. The fluid must resist oxidation and maintain its viscosity to ensure proper lubrication for the turbo bearings and valve train. These oils are compatible with the engine’s requirements for an SJ viscosity grade and offer extended service life capabilities compared to traditional mineral oils.
In addition to engine oil, the filtration system plays a vital role in maintaining engine health. The 1985 Laser requires an oil change capacity of 5.1 quarts when including the filter. It is crucial to replace the filter with a unit that can handle the increased volume of oil while trapping small contaminants that could cause wear. The AMSOIL Oil Filter EA15K51-EA is a top-tier choice, offering superior filtration efficiency and a larger capacity for wear-causing particles. For those preferring a premium aftermarket brand, the WIX Oil Filter 51348-EA provides comparable high-quality media that improves upon original equipment standards, ensuring clean oil circulates through the engine components for maximum reliability.
Transmission and Cooling System Fluids
The automatic transmission in the 1985 Chrysler Laser, specifically the A413 (31TH) model, requires a fluid that can handle the rigors of shifting while protecting internal clutches and gears. Using a synthetic automatic transmission fluid is highly recommended for vehicles that see severe driving conditions or long-term storage. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is engineered to withstand heavy towing, elevated temperatures, and challenging terrain, remaining fluid even in sub-zero environments. It provides reserve protection during heavy use, which is beneficial for older transmissions that may have experienced some wear over the years.
For a more cost-effective option that still delivers premium synthetic benefits, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers excellent protection against wear and harmful sludge. It promotes smooth, shudder-free shifts and guards against leaks, which is a common concern in aging vehicles. The total fill capacity for the A413 transmission is 8.9 quarts, with an initial fill of 4 quarts if rebuilding. Ensuring the correct fill level is essential for proper operation and to prevent transmission damage.
Cooling system maintenance is equally important for a turbocharged engine. The engine’s capacity for AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is 9 quarts. This unique poly-organic acid (OAT) formulation allows for use in a wide variety of vehicles. It is a 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses against corrosion. For owners who prefer to mix their own solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers concentrated protection that exceeds original equipment manufacturer requirements. This concentrated fluid provides protection up to 150,000 miles or 5 years in passenger cars, ensuring the engine does not overheat even under heavy load.
Finally, the hydraulic systems of the Laser, including the brakes and power steering, benefit from synthetic fluid upgrades. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides a stable viscosity across a wide temperature range, which improves brake responsiveness and safety. It is compatible with the vehicle’s MS-4574 specification requirements. For the power steering system, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid helps seals remain soft to prevent leaks and reduces friction. This fluid is formulated for quiet operation and offers excellent high-temperature protection, ensuring the steering system operates smoothly for the life of the vehicle.
Vehicle Background
The 1985 Chrysler Laser was a significant model for the American market, serving as a direct competitor to other compact coupes of the era. Developed through a joint venture between Chrysler and Mitsubishi, the Laser was built on the Mitsubishi Galant platform, blending American styling with Japanese mechanical engineering. The vehicle was known for its distinctive wedge-shaped design and modern interior, which were quite advanced for the mid-1980s. The 2.2-liter engine code [E] E Turbo variant represented the performance pinnacle of the Laser lineup, utilizing a turbocharger to boost horsepower and torque beyond what naturally aspirated engines could achieve.
This specific model was highly regarded for its handling and acceleration, making it a favorite among driving enthusiasts who wanted a sporty feel without the bulk of a full-sized American sedan. The turbocharged version introduced the benefits of forced induction to a compact chassis, offering spirited performance that was rare in the segment at the time. Owners of these vehicles often cherish the combination of the laser’s sharp looks and its punchy engine character. The platform’s shared heritage with Mitsubishi meant that the mechanical components were robust, yet they required diligent maintenance, particularly regarding cooling and lubrication, to keep the turbo system healthy. The Laser represented a unique blend of styles and technologies, marking an important chapter in Chrysler’s strategy to produce competitive, fuel-efficient, yet dynamic automobiles.
