Best motor oil for 2008 Ford Taurus 3.5L

By /

The 2008 Ford Taurus is a vehicle that demands consistent care, particularly when it comes to the liquids that keep its mechanical systems running smoothly. The 3.5L V6 engine, known for its versatility and performance, relies on high-quality synthetic lubricants to maintain efficiency, prevent wear, and extend the service life of critical components. Using the wrong viscosity or an inferior fluid can lead to reduced fuel economy, excessive engine wear, and potential transmission issues. This guide details the specific lubrication needs for this sedan, ensuring you have the correct information to maintain your vehicle properly.

Engine Oil: The Heart of Your 2008 Ford Taurus

The 2008 Ford Taurus is powered by the 3.5L 6-cylinder V6 engine. This engine requires a 5W-20 viscosity oil for optimal performance across all temperatures. The total capacity for an oil change, including the AMSOIL Oil Filter, is 5.5 quarts. It is crucial to check the oil level after refilling and to ensure the oil drain plug is torqued correctly to 20 ft/lbs.

AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil stands out as the ultimate choice for this engine. As the premier offering in the AMSOIL lineup, it delivers 75% more engine protection against horsepower loss and wear compared to industry standards. It is designed to offer guaranteed protection for up to 25,000 miles or one year, making it ideal for drivers who want to maximize their maintenance intervals without sacrificing performance. The formula is so robust that it is trusted by professional engine builders.

For owners seeking a balance between premium performance and cost, AMSOIL Extended-Life 5W-20 100% Synthetic Motor Oil is an excellent alternative. It features enhanced cleaning power to help keep the engine running smoothly for longer. This oil provides 20,000 miles of protection between changes and is specifically engineered to protect against LSPI (Low-Speed Pre-Ignition), a concern in modern direct injection engines.

If you prefer a product that closely mimics the specifications required by the factory, AMSOIL OE 5W-20 100% Synthetic Motor Oil is a perfect fit. It fights sludge and deposits effectively while protecting turbochargers significantly better than the GM dexos1 Gen 2 specification requires. This ensures your engine stays clean and efficient.

For Taurus models with AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil, specifically those with over 75,000 miles, AMSOIL 5W-20 High-Mileage Motor Oil is the recommended choice. This formula contains a boosted detergent and dispersant package along with enhanced anti-wear additives. It is proven to reduce sludge by 67%, helping older engines clean up, perform better, and last longer. It offers guaranteed protection for 12,000 miles or one year.

Filters and Air Intake

An oil change is only as good as the filter protecting the engine. The AMSOIL Oil Filter is designed to provide a filtering efficiency of 99 percent at 20 microns. This high level of filtration captures small, wear-causing contaminants that standard filters might miss. By allowing lower restriction, it helps keep engine parts lubricated and offers extended service life.

For those preferring the WIX brand, the WIX XP Oil Filter offers premium media that provides improvements over original equipment manufacturer-branded filters. Similarly, the standard WIX Oil Filter uses premium media to outperform OEM standards. The WIX Air Filter also features premium media, ensuring that clean air reaches the engine, which is vital for maintaining combustion efficiency and protecting internal components from abrasive dust.

Automatic Transmission Fluid

The 2008 Ford Taurus with the automatic transmission (specifically the 6F50 model) requires careful attention to its fluid levels. A total fill requires 10 quarts. Using a synthetic transmission fluid is highly recommended to prevent the wear, sludge, and temperature-related problems that can plague standard fluids over time.

AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is the top recommendation for this vehicle. It withstands the rigors of heavy towing, elevated temperatures, and challenging terrain. The fluid remains fluid in sub-zero temperatures, providing reserve protection during heavy use and abuse. This ensures smooth shifts and long-term transmission health.

The AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is another strong contender. It resists harmful sludge, offers excellent cold-weather performance, and guards against leaks. This fluid promotes smooth, shudder-free shifts, making it a great choice for maintaining the ride quality of your Taurus.

Differential and Transfer Case Lubes

The drivetrain components of the Taurus also require specialized lubrication. For the transfer case (PTU), AMSOIL recommends a specific viscosity. The capacity for the PTU is 1.1 pints, and the fill plug torque should be 15 ft/lbs. AMSOIL AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube is the ideal choice here. It provides advanced protection against wear, controls thermal runaway, and protects against rust and corrosion. It contains friction modifiers for limited-slip applications and helps reduce operating temperatures.

For the AWD rear differential, which requires a capacity of 2.4 pints, AMSOIL AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube is recommended. This AMSOIL SEVERE GEAR® 75W-140 100% Synthetic Gear Lube offers advanced protection in all temperatures. For other applications or limited-slip differentials, AMSOIL AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube or 75W-110 are also available options that provide long oil, seal, and equipment life while controlling thermal runaway.

AMSOIL Passenger Car & Light Truck Antifreeze & Coolant and AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid

Maintaining the cooling system is vital for the longevity of the engine. The cooling capacity for the 2008 Ford Taurus depends on the heater configuration. With the A/C and Rear Heater, the capacity is 11 quarts, while with the O/R Rear Heater, it is 13.2 quarts. AMSOIL AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free formulation that exceeds OEM requirements. It offers protection for up to 150,000 miles or 5 years. Alternatively, the concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant allows for mixing and offers similar long-term protection.

For braking safety, AMSOIL AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended choice. It provides excellent ABS and traction-control responsiveness and maintains a stable viscosity over a wide temperature range, ensuring reliable braking performance in any weather condition.

Additional Maintenance and Care

Beyond standard fluid changes, there are several other products that can enhance the performance and longevity of your Taurus. AMSOIL AMSOIL P.i.® Performance Improver Gasoline Additive is a gasoline additive that restores up to 14% horsepower and GDI fuel injectors to 100% flow rate after a single tank. It improves fuel economy and reduces the need for higher-octane fuel. For engines that may see periods of inactivity, AMSOIL AMSOIL Engine Fogging Oil is highly effective at preventing rust during storage.
