Maintaining the health of your 1987 Ford Taurus with the 3.0L V-6 engine requires more than just filling reservoirs; it demands precise fluid selection to combat the wear patterns common in late-80s transmissions and engine designs. The 3.0L OHV engine, paired with either the AXOD four-speed or ATX three-speed automatic transmissions, presents specific lubrication challenges including torque converter shudder, hydraulic sludge buildup, and thermal degradation during stop-and-go driving. Proper maintenance not only extends the life of the powertrain but also preserves the smoothness of the drive and the responsiveness of the braking system. This guide outlines the exact synthetic lubricants, capacities, and filters recommended to keep your classic Taurus running like new.
Recommended AMSOIL Products
For the 1987 Ford Taurus 3.0L, AMSOIL offers four distinct motor oil choices depending on the age and condition of your engine. The 1987 model with the 3.0L V-6 (Engine Code U) requires a total of 4.5 quarts (with filter) of 5W-30 viscosity oil. Whether you need maximum protection for high-mileage maintenance or are looking to extend intervals for a well-maintained engine, the following products provide the correct formulation.
- AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil – The ultimate choice for superior horsepower retention and wear protection, capable of lasting up to 25,000 miles or one year. This oil significantly reduces oil consumption and ensures the engine operates smoothly across all temperatures.
- AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil – An excellent option that provides 20,000 miles of guaranteed protection. It offers 37% more cleaning power than OE oils to keep older engines running smoother and helps prevent the sludge that often plagues high-mileage vehicles.
- AMSOIL OE 5W-30 100% Synthetic Motor Oil – Designed to outperform conventional oils while meeting original equipment manufacturer mileage standards. This formulation fights sludge and deposits effectively, making it a cost-effective way to upgrade your Taurus’s engine protection.
- AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil – Specifically engineered for vehicles with over 75,000 miles. It contains enhanced detergents and dispersants that reduce sludge by 67% and includes seal conditioners to help minimize oil leaks common in aging engines.
In addition to motor oil, filtration is critical for the Taurus engine. The AMSOIL Oil Filter (EAO34) is a premium choice offering 99% efficiency at 20 microns. It provides greater capacity for contaminants than standard filters, ensuring cleaner oil flow to the engine components. For those preferring a WIX alternative, the WIX XP Oil Filter also offers premium media with improvements over OEM filters, while the WIX Oil Filter remains a reliable standard option.
Transmission and Fluid Maintenance
The automatic transmissions in the 1987 Taurus are known for their specific lubrication needs, particularly regarding the shift to Mercon V specifications later in the production run. The AXOD transmission (4-speed) holds approximately 12.9 quarts for a total fill, while the 3-speed ATX holds about 8.5 quarts. To handle the heat and stress of these units, especially given their age, AMSOIL provides top-tier synthetic solutions. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid withstands heavy towing and elevated temperatures, remaining fluid even in sub-zero conditions. For excellent cold-weather performance and shudder-free shifts, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is a solid choice. If you are looking for maximum thermal protection, the AMSOIL Torque-Drive 100% Synthetic Automatic Transmission Fluid fights oxidative degradation effectively, providing long oil life for this older transmission platform.
Cooling system integrity is equally important for the 3.0L engine, which requires 9 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. This phosphate-, nitrite-, and silicate-free formulation protects all cooling system metals and hoses for up to 150,000 miles. For those who prefer a concentrated option that allows for custom mixing ratios, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers protection up to 150,000 miles in passenger cars and light trucks.
Brakes, Steering, and Fuel System Care
Braking performance on a 1987 vehicle depends heavily on the quality of the fluid, as the fluid absorbs moisture over time, lowering its boiling point. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems and maintains stable viscosity across a wide temperature range, replacing the original Motorcraft PM-1-C recommendation.
For the power steering system, which in this vehicle operates similarly to the transmission hydraulic system, AMSOIL recommends the AMSOIL Super Shift Racing Transmission Fluid. While originally a racing product, its ability to resist extreme heat and virtually eliminate slippage makes it an ideal choice for power steering systems to ensure light and precise steering control. Finally, to keep the 3.0L engine running efficiently, especially with older fuel systems, the AMSOIL P.i. Performance Improver Gasoline Additive restores fuel injectors to 100% flow rate, improving fuel economy and reducing the need for higher-octane fuels. For vehicles that are driven seasonally, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup.
Vehicle Background
The 1987 Ford Taurus represents a significant milestone in American automotive history. Introduced in the mid-1980s, the Taurus (and its companion, the Mercury Sable) launched a design revolution that moved away from the boxy, angular aesthetics of the previous decade toward the rounded, aerodynamic styling that would define the rest of the 1980s and into the 1990s. The 1987 model year was the very first year of production for this iconic sedan, making it a true “first model” vehicle for owners seeking a piece of automotive design history. Under the hood, the 3.0L V-6 engine was a workhorse, designed to provide ample torque for a heavy, aerodynamic sedan while maintaining reasonable fuel economy for its time. It was a front-wheel-drive vehicle that prioritized interior space and passenger comfort over sporty handling, though it handled the demands of a family sedan with dignity.
Owners of the 1987 Taurus often appreciate the vehicle’s smooth ride quality and the spacious cabin, which was a major selling point against competitors. However, as with any vehicle of this vintage, there are specific issues that have plagued these sedans over the decades. One common problem is oil consumption, particularly in the 3.0L V-6 engine, where valve seals can harden and wear over time, leading to oil burning. Switching to a high-mileage synthetic oil like the AMSOIL 5W-30 High-Mileage formulation can help condition seals and reduce this consumption significantly. Another frequent issue involves the transmission, specifically the AXOD and ATX units mentioned earlier. These transmissions are known for developing shudder or rough shifting due to fluid degradation and varnish buildup on the clutches. Using a high-quality synthetic transmission fluid helps dissolve existing deposits and provides a fresh, friction-modified fluid to smooth out shifts. Additionally, the cooling system can suffer from corrosion or hose degradation due to the age of the components; a modern, high-performance AMSOIL Propylene Glycol Antifreeze and Engine Coolant is essential to prevent overheating and rust buildup. Finally, the electrical system on early Tauruses can sometimes face issues with corrosion or failing sensors that affect performance; keeping the fuel system clean with regular additive treatments like AMSOIL P.i. can help maintain injector flow and ensure the engine receives the proper air-fuel mixture, preventing running rough or hesitation.
