The 2009 Lincoln Town Car with the 4.6-liter 8-cylinder engine is a classic American sedan that demands consistent maintenance to ensure its legendary ride quality and longevity. As an older vehicle, the engine components have likely experienced significant wear, making the quality of AMSOIL Signature Series Motor Oil and AMSOIL Oil Filters even more critical than when the car was new. Proper fluids protect against sludge, reduce friction, and help seal worn engine parts to prevent oil consumption. Whether you are navigating daily commutes or preparing for a long road trip, using the correct synthetic motor oil provides a level of protection that conventional oils simply cannot match.

Engine Oil Specifications and Benefits
The heart of your 2009 Lincoln Town Car is the 4.6-liter 8-cylinder V engine. To keep this powerplant running efficiently, the manufacturer specifies a 5W-20 viscosity oil. The oil capacity for a complete change, including the AMSOIL Oil Filter, is 6.0 quarts. After refilling, it is crucial to check the oil level to ensure proper lubrication. It is important to note that if you use E85 or M85 fuels, the extended drain intervals typically associated with synthetic oils can only be maintained through oil analysis, as these fuels may alter oil chemistry.
The AMSOIL Signature Series 5W-20 is the premier choice for this vehicle, offering unparalleled protection that can extend up to 25,000 miles or one year, whichever comes first. This oil provides 75% more engine protection against horsepower loss and wear compared to industry standards. For owners looking for a balanced solution, the AMSOIL Extended-Life 5W-20 offers up to 20,000 miles of guaranteed protection and features 37% more cleaning power to keep the engine running smoother for longer periods.
For those who prefer a budget-friendly option without sacrificing the benefits of synthetic technology, the AMSOIL OE 5W-20 is an excellent choice. It fights sludge and deposits with a 100% synthetic formulation. Additionally, if your Town Car has accumulated significant mileage, specifically over 75,000 miles, the AMSOIL 5W-20 High-Mileage Motor Oil is recommended. This formulation includes a unique chemistry with boosted detergents and dispersants, along with enhanced anti-wear additives. It is designed to reduce sludge by 67%, helping older engines maintain their performance and extend their lifespan. This high-mileage oil provides guaranteed protection for up to 12,000 miles or one year.
Filtration is equally critical to engine health. The AMSOIL Oil Filter (EAO11) provides filtering efficiency of 99 percent at 20 microns. This high-efficiency filtration allows for lower restriction, ensuring that engine parts remain lubricated and reducing wear caused by small contaminants. The filter also offers a greater capacity for contaminants than competing filters, which helps reduce engine wear and extends service life in accordance with industry-standard ISO SO 4548-12. For those who prefer alternative brands, the WIX XP Oil Filter (51372XP-EA) and the standard WIX Oil Filter (51372-EA) are also available, both featuring premium media that offers improvements over original equipment manufacturer-branded filters.
Transmission and Cooling System Care
The automatic transmission in the 2009 Lincoln Town Car is a 4-speed unit known as the 4R75E. Proper transmission fluid is essential for smooth shifting and preventing costly wear. The initial fill capacity is 5 quarts, while a total fill requires approximately 13.9 quarts depending on the service procedure. To ensure peak performance, AMSOIL offers Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid. This fluid is engineered to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use and abuse. For a more economical yet highly effective option, the OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid protects against wear and resists harmful sludge, promoting smooth, shudder-free shifts.
Maintaining the cooling system is vital for the longevity of the engine, especially in a heavy sedan like the Town Car. The cooling system capacity is 18.6 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ideal choice, featuring a unique poly-organic acid (OAT) formulation that allows for use in a wide variety of vehicles. It is engineered to exceed original equipment manufacturer requirements and provides protection for up to 150,000 miles or five years. This pre-mix formulation protects all cooling system metals, gaskets, and hoses while being free of phosphates, nitrates, nitrites, silicates, borates, and amines. For those who prefer concentrated fluid, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers superior protection against metallic corrosion and erosion, lasting up to 150,000 miles or five years.
Differential and Brake Fluid Recommendations
The rear differential on the Lincoln Town Car requires specific attention based on the model type. For limousine models, the standard differential requires a 75W-140 viscosity. For sedan models, the standard differential requires an 80W-90 viscosity. The differential capacity for limousine rear is 4.6 pints, while the sedan rear is 5.1 pints. Synthetic oil is required for optimal performance. The AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube is designed to control thermal runaway, protect against rust and corrosion, and help reduce operating temperatures. It contains friction modifiers suitable for limited-slip applications. Similarly, the AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube is recommended for sedan standard differentials and limited-slip differentials, offering advanced protection against wear.
Brake safety should never be compromised. The recommended brake fluid for this vehicle is a Motorcraft High Performance DOT 3 brake fluid or an equivalent meeting Ford specification WSS-M6C65-A1. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent alternative that ensures excellent ABS and traction-control responsiveness. It provides a stable viscosity over a wide temperature range, ensuring reliable braking performance in both hot and cold conditions.
Power Steering and Fluid Maintenance
The power steering system in the 2009 Lincoln Town Car utilizes a fluid system that requires specific attention. The recommended power steering fluid is MERCON V Automatic Transmission Fluid. To maintain the integrity of the power steering system, owners can utilize the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid. These fluids withstand the rigors of heavy towing and elevated temperatures, remain fluid in sub-zero conditions, and provide reserve protection during heavy use. The OE Multi-Vehicle fluid specifically protects against wear, resists harmful sludge, and guards against leaks, promoting smooth, shudder-free shifts.
About the 2009 Lincoln Town Car
The 2009 Lincoln Town Car represents the pinnacle of traditional American full-size luxury sedans. Introduced in the late 1980s, the Town Car has served as a staple for families, luxury chauffeurs, and government officials alike.
