The 2016 Lincoln MKZ 3.7L engine is a naturally aspirated V6 known for delivering smooth power and reliable performance. It requires a motor oil with a viscosity of 5W-20. The oil capacity for this engine, including the filter replacement, is 6.0 quarts. It is crucial to check the oil level after refilling and to torque the oil drain plug to 20 ft/lbs. For the transmission, the vehicle utilizes a 6-speed 6F50 automatic transmission. A total fill of this transmission requires 11.6 quarts, while the initial fill capacity is 4.5 quarts. The cooling system holds 9.7 quarts of antifreeze/AMSOIL Propylene Glycol Antifreeze and Engine Coolant. Proper fluid levels and the use of high-performance synthetic lubricants are essential to maintain the engine’s efficiency and the transmission’s responsiveness under various driving conditions.
Engine Oil and Filter Specifications
The heart of the 2016 Lincoln MKZ 3.7L is a V6 engine that benefits significantly from high-quality synthetic lubrication. AMSOIL recommends four distinct 5W-20 viscosity options depending on your vehicle’s age and your maintenance preferences. The Signature Series 5W-20 is the top-tier choice, offering up to 25,000 miles of protection and 75% more engine protection against horsepower loss and wear. This is ideal for drivers who want maximum protection for their engine. For those seeking a slightly shorter but still extended service interval, the Extended-Life 5W-20 provides up to 20,000 miles of guaranteed protection and features enhanced cleaning power. The AMSOIL OE 5W-20 is an excellent choice for standard mileage vehicles, offering a budget-friendly synthetic option that effectively fights sludge. For older vehicles with over 75,000 miles, the 5W-20 High-Mileage Motor Oil features a unique chemistry with boosted detergents to clean engines and reduced sludge by 67%. All these oils are paired with the AMSOIL Oil Filter (EAO17), which offers 99% filtration efficiency at 20 microns, or compatible aftermarket options like the WIX XP Oil Filter and WIX Oil Filter.
Transmission and Cooling Systems
The automatic transmission in this model is a critical component that requires specialized fluid to handle the rigors of heavy towing, elevated temperatures, and challenging terrain. The recommended fluid is the Signature Series Fuel-Efficient Automatic Transmission Fluid, which provides reserve protection during heavy use and remains fluid in sub-zero temperatures. For those looking for a cost-effective synthetic alternative, the AMSOIL OE Fuel-Efficient Automatic Transmission Fluid protects against wear and offers similar benefits. The engine cooling system holds a significant volume, with a capacity of 9.7 quarts. To maintain optimal operating temperatures, drivers can choose the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, a pre-mixed ethylene glycol formulation, or the Propylene Glycol Antifreeze, which is a concentrated, low-toxicity option that offers protection up to 150,000 miles.
Differential and Transfer Case Lubrication
The Lincoln MKZ 3.7L drivetrain includes a transfer case and a rear differential that require specific gear lubricants to function correctly. For the Transfer Case (PTU), the specifications call for an SAE 75W-140 synthetic rear axle lubricant. The AMSOIL SEVERE GEAR® 75W-140 is the perfect match, designed to control thermal runaway and protect limited-slip applications. The Rear Differential requires an SAE 80W-90 fluid meeting Ford specifications. For this application, the AMSOIL SEVERE GEAR® 80W-90 is highly recommended, providing advanced wear protection and reducing operating temperatures. Other viscosity options like the 75W-90 and 75W-110 are also available for various gear applications.
Brake Fluid and Performance Additives
Safety is paramount, and the braking system requires a fluid that maintains stability over a wide temperature range. The recommended fluid for the Lincoln MKZ is the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid, which ensures excellent ABS and traction-control responsiveness. For drivers looking to improve overall fuel economy and engine performance, the AMSOIL P.i.® Performance Improver is an effective gasoline additive. It restores up to 14% horsepower and can restore GDI fuel injectors to 100% flow rate after a single tank of treated fuel, helping to control pre-ignition knock.
