Engine Oil Specifications and Selection
When servicing the 1987 Mitsubishi Cordia 2.0L engine, selecting the right viscosity is critical for proper lubrication. The recommended oil grade is 10W-30, though the engine can also accept 10W-40 or 10W-50 if the ambient temperature rises above -23°C. For colder conditions below -23°C, SAE 5W-30 or 5W-40 are suitable options. In warmer climates where temperatures stay above 0°C, heavier grades like 20W-20, 20W-40, or 20W-50 may be utilized. It is important to note that SAE 5W-20 is not recommended for sustained high speeds. The oil capacity for a standard change, including the filter replacement, is 4.2 quarts. After refilling the system, it is vital to check the oil level and allow the drain plug torque to be set between 26 and 32 ft/lbs.
For owners seeking the highest level of protection, AMSOIL Signature Series 10W-30 100% Synthetic Motor Oil stands out as the top recommendation. This premium synthetic oil offers superior protection against horsepower loss and wear, ensuring the engine runs smoothly for up to 25,000 miles or one year under normal service conditions. If you prefer a slightly shorter interval with high cleaning power, the AMSOIL Extended-Life 10W-30 100% Synthetic Motor Oil provides 37% more cleaning capability to remove contaminants and keep the engine interior free of sludge. For older vehicles with significant wear, the AMSOIL 10W-30 100% Synthetic High-Mileage Motor Oil is specifically formulated with boosted detergents and dispersants to reduce sludge by 67% and enhance anti-wear additives, helping engines last longer.
The filtration system is equally important for maintaining oil quality. The WIX Oil Filter is the recommended choice for this vehicle. It features premium media that offers improvements over standard OEM-branded filters, ensuring that contaminants are effectively captured before they can circulate through the engine.
Transmission and Gear Lubrication
The lubrication needs for the 1987 Mitsubishi Cordia vary depending on whether the vehicle is equipped with a manual or automatic transmission. For the automatic transmission, specifically models KM172-0, the total fill capacity is 6.1 quarts, with an initial fill capacity of 4.2 quarts. To protect the automatic transmission from wear, sludge, and temperature-related issues, AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an ideal choice. It withstands the rigors of heavy use and remains fluid in sub-zero temperatures. Alternatively, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid promotes smooth, shudder-free shifts and provides excellent cold-weather performance.
For the manual transmission (model KM163-0, 5-speed), the fluid requirement is 4.9 pints of GL-4 75W-85W. To ensure optimal performance, AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is recommended. This AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube offers outstanding cold-flow properties and is friction-modified to protect brass synchronizers while providing long service life.
Cooling and Brake Systems
Maintaining the cooling system is crucial for the longevity of the 2.0L engine. The coolant capacity for the system is 7.4 quarts. Using a high-quality antifreeze prevents corrosion and extends the life of the cooling system components. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, and silicate-free ethylene glycol pre-mix that protects all metals and hoses for up to 150,000 miles. For those who prefer a concentrated formula, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers superior protection and can be mixed with distilled water for a custom blend.
Brake system safety cannot be overlooked. The Cordia utilizes a hydraulic brake fluid system requiring DOT 3 fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems, maintaining stable viscosity across a wide temperature range.
About the 1987 Mitsubishi Cordia
The Mitsubishi Cordia represents a fascinating chapter in Japanese automotive history, serving as a front-wheel-drive coupe that challenged the status quo of the mid-1980s. When introduced, the Cordia was notable for its aggressive, aerodynamic design, which was heavily influenced by racing aesthetics and the aerodynamic theories of the era. This vehicle shared its platform and mechanical underpinnings with the Dodge Omni and Plymouth Horizon, as well as the Mitsubishi Galant Lambda, but it distinguished itself with a more distinct and sporty European-inspired styling that set it apart from its American counterparts.
Equipped with a 2.0-liter inline-four engine, the Cordia offered a blend of modest power and fuel efficiency that was typical for the time. For the 2.0L naturally aspirated model, the engine produced roughly 100 horsepower, which provided adequate acceleration for daily driving and spirited cornering on country roads. The Cordia was designed to be a compact sports coupe that could also serve as a practical daily driver, offering a unique combination of style and utility that appealed to buyers looking for something more than a standard sedan.
Owners of the 1987 Mitsubishi Cordia today appreciate its rarity and the unique character it brings to the road. Unlike the more ubiquitous Japanese sports cars of the 80s, the Cordia has a distinctive presence that stands out in a crowd. The vehicle’s reputation for reliability is generally solid, provided it receives consistent maintenance. However, like many vehicles of its vintage, it is susceptible to issues related to age and mileage. One common problem involves the engine’s oil consumption, which can increase as the internal seals and piston rings wear over decades. Switching to the AMSOIL 10W-30 100% Synthetic High-Mileage Motor Oil can help reduce this consumption and improve engine sealing. Another frequent issue is the degradation of the rubber components in the cooling system, which can lead to leaks or overheating. Using a high-quality, phosphate-free antifreeze like the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant can prevent corrosion and extend the life of hoses and gaskets. Additionally, the manual transmission in some models may develop shifting difficulties or whining noises due to worn synchronizers or degraded lubricant; a dedicated synthetic gear lube like the AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube can alleviate these symptoms and ensure smooth gear changes. Finally, the brake systems may suffer from fluid contamination or boil-over under heavy use, making a switch to AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid a practical step to maintain optimal braking performance and safety.
Whether you are a collector preserving a classic piece of automotive history or an enthusiast enjoying a daily driver, proper fluid maintenance is the key to keeping the 1987 Mitsubishi Cordia running as intended. By selecting the correct AMSOIL synthetic products, you ensure that your vehicle receives the protection it needs to perform reliably for years to come.
