The foundation of any robust maintenance regimen for your Eclipse is selecting the appropriate motor oil. The engine bay of the 2001 Eclipse 3.0L is designed to run on SAE 5W-30, which is preferred for this specific model. The oil capacity is 4.5 quarts when a filter is installed. After refilling, it is crucial to check the oil level to ensure optimal coverage. The drain plug should be torqued to between 26 and 32 ft/lbs to prevent leaks and ensure a secure fit. When choosing the specific grade of synthetic oil, you have several distinct options depending on your driving habits. If you push your vehicle hard or enjoy long highway drives where intervals are extended, the Signature Series 5W-30 100% Synthetic Motor Oil is the ultimate choice, offering 75% more engine protection against horsepower loss and wear compared to standard oils. For those who drive in varying conditions and want robust protection with a focus on cleaning, the Extended-Life 5W-30 100% Synthetic Motor Oil offers significant cleaning power to keep the engine running smoother for longer. The OE 5W-30 100% Synthetic Motor Oil is designed to outperform conventional oils and fights sludge effectively, while the 5W-30 100% Synthetic High-Mileage Motor Oil is specifically tailored for engines with over 75,000 miles to boost cleaning power and reduce sludge.
Beyond the engine crankcase, the transmission system in your Mitsubishi Eclipse requires precise fluid management to ensure smooth shifting and longevity. For models equipped with the F4A51-2 4-speed automatic transmission, the fluid capacity varies depending on whether you are performing an initial fill or a total fill. The initial fill requires 3.7 quarts, while a complete total fill utilizes 8.9 quarts. Using a synthetic automatic transmission fluid like the Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid provides exceptional resistance to the rigors of heavy towing, elevated temperatures, and challenging terrain. This fluid remains fluid even in sub-zero temperatures, ensuring reliable shifts in any season. Alternatively, the OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an excellent choice that protects against wear and sludge while promoting smooth, shudder-free shifts and guarding against leaks. If your Eclipse features a manual transmission, specifically the F5M51-1 5-speed model, it requires AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube. This fluid offers outstanding cold-flow properties and protects brass synchronizers, ensuring precise gear engagement and long service life.
Maintaining the thermal health of the engine is equally critical, especially for a performance-oriented vehicle like the Eclipse. The cooling system capacity for this model is 8.5 quarts. Keeping the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant in peak condition prevents corrosion, overheating, and gasket failure. This unique poly-organic acid (OAT) formulation exceeds OEM requirements and offers protection up to 150,000 miles or five years. It is an ethylene glycol-based 50/50 pre-mix that protects all cooling system metals, gaskets, and hoses while being free of phosphates, nitrates, and silicates. For those who prefer a concentrated solution or plan to use it in heavy-duty conditions, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is available. This concentrated option requires mixing with distilled water and offers protection up to 150,000 miles or five years, with even longer intervals possible in heavy-duty applications. It greatly surpasses standards for metallic corrosion and erosion.
Proper maintenance extends to all fluids that circulate through your vehicle, including the steering and braking systems. The hydraulic WIX Oil Filter is recommended for certain transmission applications, but for fluids, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent responsiveness for ABS and traction control systems while maintaining a stable viscosity over a wide temperature range. The hydraulic brake fluid in your Eclipse should be DOT 3 compatible. For the power steering system, which utilizes a specific fluid type (PS016), the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is the recommended choice. This synthetic fluid reduces friction, keeps seals soft to prevent leaks, and resists heat for extended fluid life, ensuring quiet operation and strong anti-wear protection.
