2020 Ford F-150 Fluid Specs & Capacities

Quick Reference: 2020 Ford F-150 Fluid Specs

Engine Oil

For the 2020 F-150, the recommended engine oil is a full synthetic that meets Ford's WSS-M2C961-A1 specification. Depending on the engine, the viscosity grade will vary. The 3.5L EcoBoost V6, for example, specifies SAE 5W-30, while the 3.0L Power Stroke diesel requires SAE 0W-30. Always verify the correct weight in your owner's manual. Using the wrong viscosity or a non-specified oil can lead to reduced fuel economy, increased engine wear, and potential damage to timing components. Capacities range from 6.0 quarts for the 3.3L V6 up to 8.8 quarts for the 5.0L V8.

Engine Coolant

The 2020 F-150 was factory-filled with Motorcraft Yellow Prediluted Antifreeze/Coolant, which is an Organic Acid Technology (OAT) coolant. It is crucial not to mix this with other coolant types, such as the older Hybrid Organic Acid Technology (HOAT) coolants (like Motorcraft Gold), as this can cause gelling and severely restrict cooling system performance. When topping off or refilling, use only a coolant that meets Ford's specification. The cooling system capacity varies from 12.3 to 15.7 quarts depending on the engine and powertrain configuration.

Transmission Fluid

All 2020 Ford F-150s equipped with the 10-speed automatic transmission require Motorcraft MERCON ULV (Ultra-Low Viscosity) automatic transmission fluid. This is a highly specific, synthetic fluid designed for modern, high-efficiency transmissions. Never use a universal or multi-vehicle ATF. Use of a non-specified fluid can cause harsh shifting, transmission shudder, and eventual component failure. A complete fluid and filter change is a complex procedure best left to a professional, with a typical service filling around 13.1 quarts.

Transfer Case Fluid

For 4WD models, the transfer case requires Motorcraft XL-12 Transfer Case Fluid. This is a specialty fluid, and substitution is not recommended. The capacity is approximately 1.5 quarts. Service intervals are typically long, but it is essential to check for leaks and maintain the proper fluid level, especially if you frequently use four-wheel drive.

Front & Rear Differential

The front differential on 4WD models specifies Motorcraft SAE 80W-90 Premium Rear Axle Lubricant, with a capacity of around 1.8 to 2.1 quarts. The rear differential, however, requires Motorcraft SAE 75W-85 Premium Synthetic Hypoid Gear Lubricant. Some rear axles, particularly those with limited-slip differentials (LSD), may also require a friction modifier additive. Always verify if your truck's axle code specifies the need for this additive to prevent chatter and binding. Rear differential capacity is between 2.7 and 3.5 quarts.

Brake Fluid & Power Steering

The 2020 F-150 uses Motorcraft DOT 4 LV High Performance Brake Fluid. The "LV" (Low Viscosity) is critical for the proper function of modern ABS and traction control systems. Do not use standard DOT 3 or DOT 4 fluid, as it can lead to a spongy pedal feel and delayed response from the safety systems. The system should be flushed and refilled every 2-3 years as brake fluid is hygroscopic (absorbs water).

This generation of F-150 uses an Electric Power-Assisted Steering (EPAS) system, so there is no hydraulic power steering fluid to check or change.

Washer Fluid & DEF (Diesel Exhaust Fluid)

Use any quality windshield washer fluid. For the 3.0L Power Stroke diesel engine, it is critical to use a high-quality Diesel Exhaust Fluid (DEF) that is API-certified and meets ISO 22241 standards. The DEF tank holds approximately 5.0 gallons. Do not allow the DEF tank to run empty, as this will result in the vehicle entering a reduced power mode or being unable to start.
