With guaranteed protection for up to 25,000 miles or one year, this oil allows owners to extend their service intervals significantly while maintaining peak engine performance. The base stock and additive package are designed to resist oxidation and maintain viscosity even under the high temperatures generated by a naturally aspirated V-8.
For those looking for a slightly more budget-friendly option without sacrificing the benefits of synthetic technology, AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil is an excellent alternative. It offers 37% more cleaning power than the OE version to help keep the engine running smoother for longer. This option provides 20,000 miles of guaranteed protection, making it ideal for drivers who want extended intervals but may not require the absolute maximum performance of the Signature Series. The AMSOIL OE 5W-30 100% Synthetic Motor Oil is also available, offering an API Licensed product that performs well for normal service schedules, typically up to 12,000 miles.
Matching the oil with the correct filter is just as critical as the oil itself. The engine oil filter used in this vehicle must be capable of handling the flow requirements of the high-performance engine while trapping microscopic particles. The AMSOIL Oil Filter is designed to filter at 20 microns, capturing contaminants that can cause premature wear on bearings, camshafts, and piston rings. It also features a synthetic media that resists high temperatures and ensures lower restriction, allowing the oil to circulate freely to all critical components. For those who prefer to stick with the original equipment manufacturer branding, the WIX XP Oil Filter and standard WIX Oil Filter are also compatible options that offer improved media over older OEM standards.
Transmission and Differential Fluids
The 2024 Mustang is typically paired with a 10-speed automatic transmission (10R80) in the 5.0L configuration. This transmission operates under significant stress, especially when paired with the torque output of the V-8. The manufacturer specifies a specific fluid meeting Ford’s WSS-M2C949-A requirements. Using a conventional fluid may lead to sludge buildup, harsh shifting, or reduced efficiency over time. AMSOIL Signature Series ULV 100% Synthetic Automatic Transmission Fluid is specifically formulated to handle the rigors of this transmission. It remains fluid in sub-zero temperatures while providing excellent protection during high-temperature driving conditions like track days or aggressive highway merging.
The total fill capacity for the 10R80 transmission is approximately 13.1 quarts, though this can vary slightly depending on the exact fill procedure and dipstick method. When servicing the transmission, it is vital to use a fluid that protects against wear and maintains the correct friction characteristics for the clutch packs. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is another strong candidate, offering similar protection with a focus on fuel economy. For those with lower mileage or a more economical maintenance schedule, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides reliable performance that meets OEM standards.
Equally important is the rear differential. The Mustang’s 5.0L model often features a Limited Slip Differential (LSD) which requires a specific type of lubricant containing friction modifiers. Using the wrong gear oil can lead to chatter and premature wear of the clutches within the differential. The AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube is the ideal solution for the rear differential. It is specifically designed for GL-5 applications and contains the necessary friction modifiers for limited-slip units. This synthetic gear lube controls thermal runaway and reduces operating temperatures, ensuring the differential remains smooth and responsive even under heavy loads. The capacity for the rear differential is roughly 3.2 pints, and a full flush ensures all old, contaminated fluid is replaced.
Coolant, Brake Fluid, and Additives
Proper cooling system maintenance is essential for the longevity of the Coyote engine. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant must protect all metals, gaskets, and hoses from corrosion while preventing freeze or boil-over. The recommended capacity varies by transmission type and trim, generally ranging from 11.7 to 12.8 quarts.
