The 1987 Mitsubishi TREDIA is a compact sedan that served as a staple in the Japanese automotive market during the late 1980s. Powered by the G63B engine, this four-cylinder unit represents a period of Mitsubishi where durability and fuel efficiency were prioritized alongside basic comfort. The vehicle typically came with either a manual or automatic transmission, both of which benefit significantly from modern synthetic fluids that exceed the performance standards of the era. While the car was designed for a different era of fuel and maintenance schedules, the underlying mechanical components are robust, provided they receive the correct lubrication.
Understanding the specific fluid requirements for this vehicle helps owners avoid premature wear. The engine, specifically the 2.0L G63B, requires an oil viscosity that flows easily at cold temperatures yet maintains a film strength at operating heat. The recommended capacities for a standard oil change with a filter included are 4.2 quarts. This is a crucial detail because overfilling or underfilling can lead to aerated oil or insufficient lubrication, respectively. For the cooling system, the TREDIA holds 7.4 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, requiring an antifreeze that not only prevents freezing in winter but also protects the aging metal components of the radiator and engine block from corrosion.
Transmission maintenance is equally vital for preserving the driving experience. The automatic transmission, with a total fill capacity of 6.1 quarts (or 4.2 quarts for an initial fill), relies on fluid that can handle the heat generated by friction plates. For the manual transmission, the capacity is notably smaller at 4.9 pints, requiring a AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube that can handle the specific demands of the synchronizers. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid system, utilizing DOT 3 specifications, benefits from synthetic brake fluid that resists moisture absorption, which can otherwise lower the boiling point and lead to brake fade.
Several common issues affect this model line as it continues to age. One frequent problem is oil sludge buildup due to extended intervals or the use of lower-quality oils. High-performance synthetic motor oils, such as AMSOIL Signature Series 10W-30, can help dissolve existing deposits and prevent new ones from forming, ensuring that oil passages remain clear. Another issue is the degradation of rubber seals, which can lead to leaks. AMSOIL 10W-30 100% Synthetic High-Mileage Motor Oil formulations with seal conditioners are particularly effective in reducing these leaks and slowing the hardening of gaskets. Furthermore, the clutch fluid in manual transmission models can become contaminated with moisture over time, leading to a spongy pedal feel; a complete fluid flush with synthetic brake fluid can restore sharp engagement. Finally, transmission shudder or delayed shifting is often caused by fluid breakdown and varnish buildup; using a premium synthetic transmission fluid like AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can restore smooth operation and extend the life of the transmission bands and clutches.
Additional Protection and Maintenance
For owners who plan to store their TREDIA for periods of time, such as during winter months, using an oil stabilizer or fogging oil can prevent internal rust and preserve engine components. The AMSOIL Gasoline Stabilizer is an excellent choice to keep fuel systems clean during storage, preventing varnish and gum buildup that can clog carburetors or fuel injectors. Similarly, the AMSOIL Engine Fogging Oil provides a protective coating on internal parts, ensuring the engine is ready to start when the storage period ends.
In terms of general maintenance, the AMSOIL P.i. Performance Improver gasoline additive can be a powerful tool for restoring lost power and improving fuel economy. It works to clean fuel injectors and intake valves, addressing issues that often plague older vehicles. For those looking to keep their vehicle looking its best, the AMSOIL Miracle Wash offers a waterless cleaning solution that protects the paint from UV rays without the need for a traditional wash. These additional products complement the core lubrication package, ensuring a holistic approach to vehicle care.
When performing these services, always adhere to the specified capacities and torque settings. For the oil drain plug, the torque specification is between 26 and 32 ft-lbs. Always check the oil level after refilling to ensure it is within the safe operating range. By following these recommendations and utilizing the appropriate AMSOIL products, owners can keep their 1987 Mitsubishi TREDIA running smoothly and reliably for years to come.
