Engine Oil

For the 2022 model year, Ford offered three distinct engine choices for the F-250, each with a specific engine oil requirement. Using the correct oil is paramount for engine longevity, performance, and fuel economy.

• 6.2L V8: This engine calls for SAE 5W-30 Synthetic Blend motor oil that meets Ford's WSS-M2C946-B1 specification. The service fill capacity, including the filter, is 7.0 quarts (6.6L).
• 7.3L V8 "Godzilla": Ford specifies SAE 5W-30 Synthetic Blend meeting the WSS-M2C946-B1 standard. Its larger oil pan requires 8.0 quarts (7.6L) for a change.
• 6.7L Power Stroke V8 Diesel: Diesel engines have unique needs. The Power Stroke requires SAE 10W-30 Diesel Motor Oil that meets Ford specification WSS-M2C171-F1 and API service category CK-4. The capacity is 13.0 quarts (12.3L). Using a non-diesel-rated oil can lead to premature wear and damage to emissions components.

Notes: Always verify the API donut on the bottle. For the gasoline engines, look for the API SP or SN Plus rating. For the diesel, API CK-4 is essential. Using high-quality oil and a new filter at every service interval recommended in your owner's manual is the single best thing you can do for your truck's powertrain.

Engine Coolant

The 2022 F-250 uses Motorcraft Orange Prediluted Antifreeze/Coolant, which conforms to Ford specification WSS-M97B44-D2. This is an Organic Acid Technology (OAT) coolant.

It is critical not to mix coolant types. Never add green, yellow, pink, or purple coolants to the system. Mixing an OAT with a Hybrid OAT (HOAT) or older Inorganic Acid Technology (IAT) coolant can cause it to gel, leading to blockages, overheating, and costly damage to the radiator, heater core, and water pump. If you are unsure what coolant is in the system, a complete flush is the safest course of action.

System capacity varies by engine and equipment, ranging from 20.8 to 29.1 quarts (19.7 - 27.5L). Always use a 50/50 mix of distilled water and concentrated coolant, or buy the premixed version to ensure proper freeze and corrosion protection.

Transmission & Drivetrain Fluids

Automatic Transmission Fluid

All 2022 Ford F-250s are equipped with the TorqShift 10-speed (10R140) automatic transmission. This advanced transmission requires a specific, low-viscosity fluid: Motorcraft MERCON ULV (Ultra-Low Viscosity), meeting Ford specification WSS-M2C949-A.

CRITICAL NOTE: Do not use conventional MERCON V, MERCON LV, or any "universal" ATF. Using the wrong fluid will lead to poor shifting, shuddering, and eventual transmission failure. MERCON ULV is not interchangeable with other fluids. A complete fluid and filter service requires approximately 17.8 quarts (16.8L).

Transfer Case Fluid (4WD Models)

Four-wheel-drive models require Motorcraft Transfer Case Fluid (XL-12). The capacity is approximately 2.0 quarts (1.9L). This is a straightforward drain-and-fill procedure.

Differential Fluid

• Front Axle: The front differential requires SAE 80W-90 gear oil meeting Ford's WSS-M2C945-A spec. Capacity is 2.9 quarts (2.7L).
• Rear Axle: The rear differential specifies SAE 75W-140 Synthetic Rear Axle Lubricant. Crucially, if your truck is equipped with a limited-slip differential (LSD), you must also add Motorcraft Friction Modifier (XL-3). A failure to add this additive will result in clutch chatter and binding during turns. The fluid must meet spec WSL-M2C192-A. Capacity is 3.5 - 3.7 quarts (3.3 - 3.5L) depending on the specific axle.

Brake, Steering, and Other Fluids

Brake Fluid

Ford specifies Motorcraft DOT 4 LV High Performance Motor Vehicle Brake Fluid. The "LV" stands for Low Viscosity, which is essential for the proper operation of modern ABS and stability control systems. While DOT 3 or standard DOT 4 will work in an emergency, the system should be flushed and filled with the correct DOT 4 LV fluid as soon as possible for optimal safety performance.

Power Steering Fluid

Despite the move to electric power steering in lighter vehicles, the Super Duty retains a robust hydraulic power steering system. It requires Motorcraft MERCON LV automatic transmission fluid. Do not confuse this with MERCON ULV for the transmission. The system is "fill for life," but should be checked periodically and topped off if needed.

Diesel Exhaust Fluid (DEF) (6.7L Power Stroke only)

If you have the 6.7L Power Stroke diesel, you must keep the Diesel Exhaust Fluid (DEF) tank full. Use only high-quality DEF that is API certified and meets ISO 22241. The F-250 has a 7.5-gallon (28.4L) DEF tank. Running the tank dry will cause the truck to enter a reduced power mode and eventually prevent it from starting.

Windshield Washer Fluid

Use any quality, brand-name windshield washer solvent. In colder climates, ensure it is rated for freezing temperatures.
