For owners who prefer a different brand, the WIX Oil Filter is also a compatible option that meets or exceeds OEM standards.
Once the engine is protected, attention must be turned to the rest of the drivetrain and cooling systems. The Eclipse Cross is equipped with a Continuously Variable Transmission (CVT) that relies on specific fluid properties to function correctly. The AMSOIL 100% Synthetic CVT Fluid offers superior metal-to-metal frictional properties, ensuring smooth shifts and protecting the transmission from wear, even under severe driving conditions.
Maintaining the cooling system is equally critical, particularly for a turbocharged engine. The Eclipse Cross requires 6.3 quarts of antifreeze. You can use the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, which is a pre-mixed, phosphate-free formula that protects against corrosion and overheating for up to 150,000 miles. For those who prefer a concentrated solution that requires mixing with distilled water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant provides a high-boiling point and excellent freeze protection.
Brake safety should never be compromised. The correct fluid ensures consistent pedal feel and reliable stopping power. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent upgrade. It offers a stable viscosity over a wide temperature range and resists moisture absorption, which can lead to boiling points dropping dangerously low during heavy braking.
Additionally, keeping the fuel system clean helps maintain the efficiency of your turbocharger and fuel injectors. The AMSOIL P.i. Performance Improver is a potent gasoline additive that helps restore lost horsepower and improves fuel economy by cleaning fuel injectors and intake valves.
Why Proper Lubrication Matters for the Eclipse Cross
The 2023 Mitsubishi Eclipse Cross features a sophisticated 1.5-liter turbocharged engine that is sensitive to fluid quality. Turbochargers spin at incredibly high speeds and generate significant heat, making oil quality paramount. Standard conventional oils can break down under this thermal stress, leading to increased wear on the turbo bearings and the rest of the engine components. Synthetic lubricants like those listed above are engineered to resist thermal breakdown, maintaining their viscosity and protective properties even when the engine is running hot.
Beyond the engine, the transmission plays a major role in the vehicle’s driving dynamics. A CVT transmission relies on fluid friction to transmit power. Using a fluid that is not specifically formulated for this transmission type can lead to shuddering, poor acceleration response, and premature wear. AMSOIL’s synthetic CVT fluid is designed to match the precise friction characteristics required by the Eclipse Cross, ensuring that the driving experience remains smooth and responsive.
The cooling system is another critical area. The 1.5L engine runs hotter than naturally aspirated engines due to the boost pressure from the turbocharger. If the coolant loses its anti-corrosive properties or its ability to transfer heat, the engine is at risk of overheating or suffering from internal corrosion, which can lead to costly repairs. The AMSOIL antifreeze and coolant options provide a barrier against rust and corrosion while maintaining optimal heat transfer capabilities.
Furthermore, the braking system’s performance is directly tied to the condition of the brake fluid. Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This absorbed moisture lowers the fluid’s boiling point, which can result in a spongy brake pedal and reduced stopping power in emergency situations. Switching to a high-quality synthetic brake fluid like AMSOIL’s DOT 3/DOT 4 formula helps prevent this moisture absorption, keeping your braking system reliable season after season.
