Filter selection is just as critical as the oil itself. The engine relies on a high-efficiency filtration system to capture small, wear-causing contaminants before they can cause damage to bearings and cylinders. The AMSOIL Oil Filter (EAO11-EA and EAO15-EA) is engineered to provide filtering efficiency of 99 percent at 20 microns. This level of filtration is significantly higher than many standard paper filters, ensuring that the oil circulating through your engine remains clean. For those who prefer aftermarket brands, the WIX XP Oil Filter and WIX Oil Filter also offer premium media that improves upon the original equipment manufacturer branded filters, ensuring optimal flow and filtration for synthetic motor oils.

Transmission and Cooling System Care

The 2001 Explorer Sport Trac is equipped with a 5-speed automatic transmission, specifically the 5R55E. This transmission requires precise fluid characteristics to ensure smooth shifts and long-term durability. The fluid capacity varies slightly depending on whether the vehicle is a 2WD or 4WD model, with the 2WD (RWD) requiring a total fill of 10 quarts and the 4WD requiring 10.4 quarts. AMSOIL transmission fluids are formulated to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain, making them ideal for the work-oriented nature of the Sport Trac platform. The Signature Series Multi-Vehicle fluid remains fluid in sub-zero temperatures, while the OE Multi-Vehicle option offers a cost-effective solution that resists sludge and guards against leaks.

Proper cooling is essential for the longevity of the transmission and the engine. The cooling system capacity for this vehicle is 13.9 quarts. Over time, coolant degrades and loses its ability to protect metal components from corrosion and cavitation. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant utilizes a unique poly-organic acid (OAT) formulation that is free from phosphates, nitrates, and silicates, making it compatible with all other antifreeze colors and cooling system materials. It offers protection up to 150,000 miles or 5 years.
