The 2012 Mitsubishi Galant utilizes a 2.4-liter inline-four engine that requires 4.5 quarts of 5W-20 motor oil for optimal performance in most climates, with 10W-30 recommended for temperatures above 38°C. The oil pan drain plug torque specification is critical to ensure a proper seal, requiring a tightening force between 26 and 32 ft/lbs. After refilling, it is essential to check the oil level to verify the correct volume has been added. For the automatic transmission, the total fill capacity is 8.1 quarts for the F4A4B-4 speed unit. The cooling system holds 8.5 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Using the recommended fluids ensures that the transmission shifts smoothly and the engine maintains operating temperatures within safe limits, preventing costly repairs down the road.
Air Filtration and Fluid Maintenance
A clean WIX Air Filter is just as important as fresh oil for engine longevity. The filter is recommended for this vehicle to ensure the engine receives clean airflow, which supports combustion efficiency and power output. Beyond the engine and transmission, maintaining the brake system is vital for safety. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers superior resistance to moisture absorption, which lowers the boiling point and can cause brake fade. Additionally, the power steering system benefits from the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid, which is formulated to keep seals soft and prevent leaks while providing excellent high-temperature protection.
Comprehensive Coolant Protection
Proper cooling system maintenance is often overlooked until a problem arises. The 2012 Galant requires a coolant that protects against corrosion and erosion while preventing the degradation of rubber hoses and gaskets. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed solution that meets or exceeds original equipment manufacturer requirements. For those who prefer concentrated coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended protection for up to 150,000 miles or five years. Both options are designed to safeguard the engine’s internal metal components and the cooling system’s integrity against harsh temperature fluctuations.
