Keeping your 2016 Ford Mustang 3.7L Pony running at its peak requires more than just filling up the gas tank; it demands precision in choosing the right lubricants for every component. The 3.7L V6 engine is a robust workhorse, but like any internal combustion engine, it relies heavily on the quality of motor oil, filters, and fluids to manage heat, reduce friction, and protect against wear. Whether you are enjoying spirited drives on the highway or putting in the miles for a daily commute, using the correct viscosity and specification fluids ensures longevity and optimal performance.
The 3.7L engine, identified by the engine code [M] and 99M M, has specific fluid capacities and requirements that standard oils often cannot meet. For instance, the engine requires a 5W-20 viscosity to ensure proper flow during cold starts and protection at operating temperatures. The cooling system also demands a precise amount of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant to handle the thermal load generated by the combustion process, while the transmission and differential rely on specialized synthetic lubricants to prevent shudder, wear, and thermal runaway. By adhering to the manufacturer’s specifications and upgrading to high-performance synthetic alternatives, owners can extend service intervals and reduce the risk of component failure.

Engine Oil Selection for the 3.7L V6
For the 3.7L engine found in the 2016 Ford Mustang, the oil capacity is 6.0 quarts when the oil filter is also replaced. Selecting the correct viscosity is crucial for maintaining oil pressure and ensuring that moving parts are adequately lubricated during startup. The manufacturer specification calls for 5W-20, a weight that balances low-temperature flow with high-temperature stability. While the vehicle will run on conventional oil, synthetic options provide a distinct advantage in reducing friction and handling the thermal stress generated by the V6 configuration.
AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil stands out as the premier choice for those seeking maximum protection. It is engineered to deliver up to 25,000 miles of protection between changes, provided the vehicle is driven under normal service conditions. This oil is significantly thicker at operating temperatures than conventional oils of the same grade, ensuring a robust lubricating film even under high stress. It offers 75% more engine protection against horsepower loss and wear compared to conventional oils, helping to maintain the power output of the Mustang over time.
For drivers who prefer a slightly shorter interval but still want superior synthetic benefits, AMSOIL Extended-Life 5W-20 100% Synthetic Motor Oil is an excellent alternative. This formulation provides up to 20,000 miles of protection and features a cleaning package that helps prevent deposit buildup. It is particularly effective at keeping the engine running smoother for longer. If you are looking for a budget-friendly synthetic option that still outperforms conventional oils, the AMSOIL OE 5W-20 is designed to fight sludge and deposits while meeting the specific requirements of modern engines.
Owners of Mustangs with higher mileage should consider the AMSOIL 5W-20 100% Synthetic High-Mileage Motor Oil. This product contains boosted detergent and dispersant packages and enhanced anti-wear additives. It is specifically formulated to reduce sludge by 67%, cleaning the engine and ensuring better performance. This oil is ideal for vehicles that have surpassed the 75,000-mile mark, offering a unique chemistry to help older engines last longer and perform better.
Filtration is just as critical as the oil itself. The recommended oil filter for this engine is the AMSOIL Oil Filter, which provides filtering efficiency of 99 percent at 20 microns. This high efficiency allows lower restriction, keeping engine parts lubricated and reducing wear. The filter also offers greater capacity for small, wear-causing contaminants than competing filters, ensuring that the oil remains clean throughout the extended service interval. For those who prefer aftermarket brands, the WIX XP Oil Filter and WIX Oil Filter are also suitable alternatives that meet the vehicle’s filtration requirements.
Transmission and Drivetrain Fluids
The cooling of the drivetrain and the protection of transmission components are vital for the longevity of the 2016 Mustang. The automatic transmission (6R80) has a capacity of 3.5 quarts for an initial fill, with a total fill capacity of 12 quarts. The manual transmission (MT82) requires a specific synthetic fluid due to its tight tolerances. Using the correct fluid prevents shudder, ensures smooth shifts, and protects against the high thermal loads experienced during spirited driving.
For the automatic transmission, AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is highly recommended. It is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. This fluid remains fluid in sub-zero temperatures and provides reserve protection during heavy use, ensuring the transmission shifts smoothly even under stress. For the manual transmission, AMSOIL 100% Synthetic DCT Fluid is the ideal choice. It offers outstanding wear protection and is specifically designed to prevent shudder, making it perfect for the 6-speed MT82 found in this Mustang model.
Cooling System and Brake Fluid
The cooling system in the 2016 Mustang holds 12.4 quarts of coolant. Maintaining this system is essential to prevent overheating, which can lead to catastrophic engine damage. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free formulation that protects all cooling system metals, gaskets, and hoses. It offers protection for up to 150,000 miles or 5 years, whichever comes first, eliminating the need for frequent flushes.
Alternatively, AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that requires mixing with distilled water. This eco-friendly coolant greatly surpasses standards for metallic corrosion and erosion, providing up to 1,000,000 miles of protection in heavy-duty applications.
