Keeping a 2007 Lincoln Town Car with the 4.6-liter V8 engine running smoothly requires more than just following a standard maintenance schedule; it demands the use of fluids engineered for the specific tolerances and thermal characteristics of this classic full-size sedan. While the factory recommendations provide a baseline, synthetic lubricants offer a significant upgrade in protection, particularly against the high temperatures and extended drain intervals that modern vehicles often encounter. The 4.6-liter engine, known for its smooth operation and durability, benefits greatly from the superior thermal stability and cleaning power of AMSOIL Signature Series Motor Oil or AMSOIL Extended-Life Motor Oil, which help maintain oil pressure and reduce wear on critical components like cam phasers and valve train parts. For the drivetrain, the 4R75E automatic transmission and the rear differential require precise viscosity and friction modifiers to ensure smooth shifting and prevent the wear that can lead to costly repairs down the road.

The engine oil capacity for the 2007 Lincoln Town Car with the 4.6-liter V8 is 6.0 quarts when the AMSOIL Oil Filter is replaced. It is critical to use a 5W-20 viscosity grade, which is specified for all temperature conditions in this application. After the refill, always verify the oil level to ensure it is within the safe operating range. The torque specification for the oil drain plug is 17 ft-lbs, a detail that should not be overlooked to prevent stripping the plug or damaging the drain pan thread. If the vehicle is running on E85 or M85 fuels, it is important to note that while extended oil drains can be considered, they should only be validated through oil analysis, as these fuels can alter oil life dynamics.
Beyond the engine, the cooling system is another critical area for maintenance. The 2007 Town Car has a coolant capacity of 18.6 quarts. Owners have a choice between two excellent AMSOIL antifreeze options. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol-based, 50/50 pre-mix that requires no additional water and provides protection against corrosion for up to 150,000 miles. For those who prefer a concentrated formula, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a more environmentally friendly option that must be mixed with distilled water. Both products are free of phosphates, nitrates, and silicates, ensuring compatibility with the various metals and rubber components in the cooling system.
The automatic transmission in this vehicle is the 4R75E. While the initial fill requires 5 quarts, the total fill capacity is 13.9 quarts. Using a high-performance synthetic transmission fluid is essential for this unit, as it helps manage the heat generated during driving and ensures smooth shifts. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is ideal for those who tow heavy loads or drive in extreme conditions, as it resists breakdown and maintains fluidity even in sub-zero temperatures. For standard maintenance, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers a robust alternative that guards against leaks and promotes smooth, shudder-free operation. Replacing the transmission fluid should also include a filter change; the WIX Transmission Filter is a compatible choice that helps maintain the cleanliness of the system.
Differentiation between the sedan and limousine models is important for differential service. The sedan requires 80W-90 or 75W-90 or 75W-110 gear lube depending on the specific differential requirements, with a capacity of 5.1 pints for the standard rear differential. The limousine model, due to its heavier load and specific axle configuration, requires a 75W-140 lubricant, with a capacity of 4.6 pints. For limited-slip differentials, particularly in limousines with Traction-Lok axles, it is recommended to add 4oz of friction modifier to the gear lube, equivalent to Ford part number XL-3 or a formulation meeting Ford spec EST-M2C118-A. The AMSOIL SEVERE GEAR line covers all these viscosity requirements, providing advanced protection against wear and rust while reducing operating temperatures.
For the braking system, the 2007 Town Car uses Motorcraft High Performance DOT 3 brake fluid, or an equivalent meeting Ford specification WSS-M6C65-A1. AMSOIL offers a DOT 3 and DOT 4 100% Synthetic Brake Fluid that exceeds these requirements. Its high boiling point and stable viscosity ensure that brake performance remains consistent even under the heavy use of a large vehicle, providing excellent responsiveness for the ABS and traction control systems. Additionally, for the power steering system, the fluid recommended can be the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid, as per Technical Service Bulletin 07-1-7, which updated the recommendation from Mercon to allow for Mercon V and synthetic alternatives for better performance.
About the Vehicle
The 2007 Lincoln Town Car represents the pinnacle of American full-size luxury sedans, a vehicle that has been a staple on the roads for decades. Built on the Ford Panther platform, this model is renowned for its spacious interior, smooth ride quality, and robust mechanicals. The 4.6-liter Modular V8 engine, which powers this vehicle, is a masterpiece of American engineering, known for its durability and ability to run for hundreds of thousands of miles when properly maintained. This engine is a naturally aspirated, overhead cam unit that delivers smooth power with a distinctive deep rumble, characteristic of the Lincoln brand. It was designed with longevity in mind, featuring a robust block and a valvetrain that is relatively low-stress compared to more modern, high-revving engines.
Owners of the 2007 Town Car often appreciate its ride comfort, which is superior to many modern sedans. The car’s large wheelbase and rear-wheel-drive layout contribute to a stable and composed driving experience, making it a favorite for chauffeurs, law enforcement, and long-distance commuters. The interior is equally impressive, offering ample legroom in both the front and rear seats, making it a comfortable choice for passengers. The trunk space is cavernous, easily accommodating large luggage loads, which adds to its practicality as a daily driver or a special occasion vehicle. The 2007 model year continues the legacy of the Town Car, offering a blend of classic luxury and modern safety features that made the platform a leader in its segment.
Despite its reputation for reliability, the 2007 Lincoln Town Car does have a few known issues that owners should be aware of. One common problem is the failure of the crankshaft position sensor, which can cause the engine to stall or fail to start. Using high-quality synthetic oils like the Signature Series or Extended-Life that provide superior cleaning power can help prevent the buildup of deposits that sometimes contribute to sensor issues. Another issue is related to the power steering system, where leaks can develop over time due to the deterioration of seals. AMSOIL OE Multi-Vehicle Synthetic Automatic Transmission Fluid used in power steering applications can often help extend the life of these seals and reduce the likelihood of leaks. Additionally, some owners report issues with the cooling system, specifically thermostat housing leaks or radiator failures. Regular use of AMSOIL Antifreeze & Coolant can help mitigate the risk of corrosion and overheating, protecting the engine block and radiator from premature failure. Finally, the 4.6-liter engine can be prone to timing chain stretch in high-mileage applications. Using a high-detergent synthetic motor oil like the AMSOIL 5W-20 High-Mileage Motor Oil can help keep the chain tensioners clean and functioning properly, potentially delaying the need for expensive timing chain services.
For those who keep this vehicle in storage during winter months, AMSOIL also offers products to ensure readiness for the next drive. The AMSOIL Gasoline Stabilizer can be added to the fuel tank to keep the gasoline fresh for up to 12 months, preventing varnish and gum buildup that can clog fuel injectors. Similarly, the AMSOIL Engine Fogging Oil is an excellent preventative measure for long-term storage, coating internal engine components with a protective film to prevent rust and corrosion. These additions, combined with the core lubrication upgrades, ensure that the 2007 Lincoln Town Car remains a reliable and comfortable cruiser for years to come.
