Keeping your 2016 Ford Expedition with the 3.5L EcoBoost V6 engine running smoothly requires more than just a standard oil change; it demands lubricants specifically engineered to handle the stresses of a turbocharged powertrain. This heavy-duty SUV is often used for towing and hauling, which places significant thermal and mechanical loads on the engine and drivetrain components. By utilizing high-quality synthetic lubricants, you can ensure superior protection against wear, extend the intervals between service, and maintain optimal performance in extreme temperatures.

Proper fluid selection is critical for the 3.5L EcoBoost engine found in your 2016 Expedition. The turbocharged design creates significantly higher operating temperatures and pressures compared to naturally aspirated engines. Standard conventional oils can break down under this stress, leading to increased wear, oil sludge, and potential turbocharger failure. AMSOIL synthetic motor oils are designed to withstand these extreme conditions, maintaining their viscosity and protective properties for longer periods. For this engine, a 6-quart capacity is required for a complete change with filter. Ensuring the oil reaches the torque specification of 20 ft-lbs for the drain plug is also vital to prevent leaks while ensuring the plug is secure.
Transmission and Drivetrain Fluids
The automatic transmission in your Expedition, typically the 6R80, operates under heavy loads, especially when towing or driving in challenging terrain. Using a fluid that can handle high heat and shear stress is essential to prevent shifting issues and extend the life of the transmission. For initial fills, approximately 3.5 quarts are needed, while a total fill for the 6-speed transmission requires about 13.1 quarts. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid are formulated to remain fluid in sub-zero temperatures while providing reserve protection during heavy use, reducing the risk of thermal runaway.
The drivetrain of the Expedition also requires specialized attention. Both the transfer case and differentials benefit from synthetic gear lubes that offer superior lubrication and thermal stability. For the front differential, the capacity is 3.6 pints of 75W-85 synthetic gear lube. The standard rear differential requires 4.4 pints, while the limited-slip (LSD) rear differential holds 4.2 pints. In all these applications, a synthetic formulation is required to meet the manufacturer’s specifications for the WSS-M2C942-A standard. AMSOIL SEVERE GEAR 75W-85 provides the necessary friction modifiers for limited-slip differentials while protecting against rust and corrosion, helping to reduce operating temperatures and extend the life of seals and equipment.
Cooling and Brake Systems
Maintaining the cooling system is paramount for the longevity of the EcoBoost engine. The cooling capacity varies slightly depending on the specific configuration, generally requiring around 18 to 18.5 quarts of coolant. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a ready-to-use, 50/50 pre-mix formulation that is free of phosphates, nitrates, and other harsh additives that can degrade seals. It protects all cooling system metals, gaskets, and hoses, ensuring your vehicle stays cool even during intense use. Alternatively, the Propylene Glycol concentrate offers extended life up to 150,000 miles, though it requires mixing with distilled water.
Brake performance is another critical safety factor. The 2016 Ford Expedition utilizes high-performance brake systems that benefit from fluid with a high boiling point. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures stable viscosity across a wide temperature range, providing excellent responsiveness for ABS and traction control systems. This fluid meets or exceeds the Ford specification WSS-M6C65-A1, ensuring that your braking system remains reliable in all weather conditions.
Additional Maintenance Products
Regular maintenance also includes attention to fuel system health and vehicle storage. AMSOIL P.i. Performance Improver is a gasoline additive that can restore up to 14% horsepower and clean GDI fuel injectors back to 100% flow rate after just one tank of fuel. It helps control pre-ignition knock and reduces the need for higher-octane fuel. For seasonal storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, protecting against varnish and gum buildup, while the AMSOIL Engine Fogging Oil guards internal components against rust during periods of inactivity. Additionally, the AMSOIL Engine Degreaser offers a professional-strength formula to remove the toughest grease and grime from engine surfaces, keeping your Expedition looking as clean as it runs. For added fuel system maintenance, consider the WIX Fuel Filters and AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor.
