Selecting the correct motor oil is the first step in preserving the longevity of your Lincoln Town Car. The 4.6-liter engine requires a 5W-20 viscosity to ensure proper lubrication across all operating temperatures. Using a premium synthetic motor oil significantly outperforms conventional oils, offering superior resistance to breakdown, oxidation, and sludge formation. For drivers seeking the absolute best protection, the AMSOIL Signature Series 5W-20 is engineered to protect against horsepower loss and wear, with a guaranteed service interval of up to 25,000 miles. This product is ideal for those who tow heavy loads, drive in extreme heat or cold, or simply want the longest possible time between oil changes. If you prefer a high-quality alternative that still offers extended intervals, the AMSOIL Extended-Life 5W-20 provides 20,000 miles of protection with enhanced cleaning power. For owners of older vehicles with high mileage, the AMSOIL 5W-20 High-Mileage Motor Oil features a unique chemistry to boost detergency, reduce sludge, and help seal minor leaks, ensuring the engine runs smoother and lasts longer.
While the oil itself is critical, the filter plays an equally vital role in engine health. An oil filter must be able to trap contaminants to prevent them from circulating through the engine and causing wear. The AMSOIL Oil Filter is designed to provide 99% filtration efficiency at 20 microns, which is significantly more effective than many stock filters. It features a greater capacity for small, wear-causing contaminants, helping to reduce engine wear and allowing for lower restriction during flow. For those who prefer OEM brands, the WIX Oil Filter and WIX XP Oil Filter are also recommended, offering premium media that improves upon original equipment specifications.
The cooling system of the Town Car requires attention to prevent overheating and corrosion, especially as the vehicle ages. The 2008 model calls for a substantial amount of coolant, with a total capacity of 18.6 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed, ethylene glycol formulation that protects all cooling system metals, gaskets, and hoses. It is free of phosphates, nitrates, and other harmful chemicals, ensuring a long-lasting shield against corrosion. For those who prefer a concentrate, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers the same long-life protection and can be mixed with water to achieve the desired concentration. This product is suitable for both passenger cars and light trucks, providing up to 150,000 miles or 5 years of protection.
Transmission health is essential for the smooth operation of the 4-speed 4R75E automatic transmission found in this vehicle. Regular fluid changes prevent wear and sludge buildup, ensuring smooth shifts and preventing costly repairs. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is specifically formulated to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures, providing reserve protection during heavy use. For a more budget-friendly yet still high-performance option, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers excellent cold-weather performance and guards against leaks, promoting smooth, shudder-free shifts. The WIX Transmission Filter is also recommended to ensure that the new fluid is kept clean as it circulates.
The differential systems in the Lincoln Town Car require specific gear lubricants to handle the heavy loads and torque of the V8 engine. For the rear standard differential in the sedan, a GL-5 rated fluid is necessary, and the recommended viscosity is 80W-90. The AMSOIL SEVERE GEAR® 80W-90 provides advanced protection against wear, controls thermal runaway, and helps reduce operating temperatures. For the limousine version, which has a different differential setup, the recommended fluid is 75W-140. The AMSOIL SEVERE GEAR® 75W-140 is a premium synthetic lubricant that contains friction modifiers specifically designed for limited-slip applications, ensuring reliable performance. If your vehicle has a limited-slip differential, a 4-ounce friction modifier should be added to meet Ford specifications. Other available options include SEVERE GEAR® 75W-90 and SEVERE GEAR® 75W-110, which offer versatile synthetic protection for various differential needs.
Brake safety is paramount for any vehicle, and the Town Car requires a high-performance DOT 3 and DOT 4 fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent responsiveness for ABS and traction-control systems. Its stable viscosity over a wide temperature range guarantees consistent braking performance in both hot and cold conditions. Additionally, for owners of older vehicles or those planning seasonal storage, products like AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, protecting against varnish and gum buildup. The AMSOIL P.i.® Performance Improver can also be used to restore horsepower and improve fuel economy by cleaning injectors and carbon deposits.
