Engine Oil

6.2L Gasoline Engine: The 2017 Ford F-250 Super Duty equipped with the 6.2L V8 gasoline engine requires SAE 5W-20 engine oil. It is crucial to use oil that meets or exceeds Ford specification WSS-M2C930-A and is API certified as SN or a newer standard (e.g., SP). The capacity with a new filter is approximately 7.0 quarts (6.6 liters). Always verify the exact capacity and latest specification in your owner's manual, as specifications can be superseded.

6.7L Power Stroke Diesel Engine: For the 6.7L Power Stroke V8 diesel engine, use an SAE 10W-30 engine oil. This oil must meet or exceed Ford specification WSS-M2C171-F1 or its subsequent revisions. Additionally, it must be API certified as CK-4, which is designed for high-speed four-stroke diesel engines and is backward compatible with most engines requiring CJ-4. The oil capacity for the 6.7L diesel engine with a new filter is a substantial 13.0 quarts (12.3 liters). Precise adherence to the manufacturer's specification is paramount for the longevity and performance of your diesel engine, especially considering the advanced emissions systems. Regular oil and filter changes are critical; refer to your owner's manual for the recommended service interval, which can vary based on driving conditions.

Engine Coolant

All 2017 Ford F-250 Super Duty models utilize Motorcraft Orange Antifreeze/Coolant, which is an Organic Acid Technology (OAT) coolant. This coolant meets Ford specification WSS-M97B44-D2. It is vital to use only this specific type of coolant or an aftermarket equivalent that explicitly states compliance with Ford WSS-M97B44-D2. Never mix different colors or types of coolants (e.g., OAT with HOAT or IAT), as doing so can lead to chemical reactions, gel formation, and severe damage to the cooling system and engine components. The total cooling system capacity varies slightly but is approximately 23.5-26.0 quarts (22.2-24.6 liters). Coolant should not be topped off with plain water, but with a 50/50 mix of distilled water and the specified Motorcraft Orange coolant. Refer to your owner's manual for the recommended service interval, typically every 100,000 miles or five years, whichever comes first.

Transmission Fluid

The 2017 F-250 Super Duty typically comes with the 6R140 TorqShift automatic transmission. This transmission requires MERCON® LV Automatic Transmission Fluid. It is absolutely critical to use only MERCON® LV fluid and never substitute with other types of ATF such as MERCON® V, Dexron VI, or ATF+4. MERCON® LV has specific friction modifiers and properties engineered for this transmission. Using an incorrect fluid can lead to premature wear, poor shift quality, and transmission failure. The approximate dry fill capacity is 17.5 quarts (16.5 liters). A complete fluid exchange is recommended at specified intervals, usually around 150,000 miles under normal driving conditions, or sooner under severe duty. Always check the fluid level using the procedure outlined in your owner's manual, usually when the transmission is at operating temperature.

Transfer Case Fluid

For 4WD/AWD models of the 2017 F-250 Super Duty, the BorgWarner BW 44-69 or BW 44-79 transfer case also specifies MERCON® LV Automatic Transmission Fluid. Just as with the transmission, using the correct MERCON® LV fluid is non-negotiable. The approximate capacity is 2.0 quarts (1.9 liters). Regular inspection and fluid changes, particularly for vehicles used in demanding conditions (e.g., off-roading, heavy towing), are vital. Consult your owner's manual for the specific service intervals.

Differential Fluid

Front Differentials: The 2017 F-250 Super Duty can come with different front axle designs. The Dana M275 front axle typically requires SAE 80W-90, API GL-5 gear oil, with a capacity of 2.9-3.4 quarts (2.7-3.2 liters). The Dana S180 front axle commonly specifies SAE 75W-85, API GL-5 gear oil, with a capacity of 2.7-2.9 quarts (2.6-2.7 liters). Always verify your specific axle type and the exact fluid requirement in your owner's manual or OEM service information.

Rear Differentials: The rear differential can be either a Sterling 10.5 or a Dana M275. Both typically require SAE 75W-140, API GL-5 gear oil. For vehicles equipped with a limited-slip differential (LSD), a friction modifier additive must be added to the gear oil to ensure proper operation and prevent chatter. Many aftermarket 75W-140 gear oils come with the friction modifier already blended in – look for this on the product label. If not, a separate Motorcraft friction modifier (XL-3) should be added. The Sterling 10.5 rear differential has a capacity of approximately 3.5-4.0 quarts (3.3-3.8 liters), while the Dana M275 rear differential holds around 4.0-4.2 quarts (3.8-4.0 liters). Consult your owner's manual for exact capacities and maintenance schedules, particularly important for hauling and towing vehicles.

Brake Fluid

The 2017 Ford F-250 Super Duty uses Motorcraft DOT 4 LV High Performance Motor Vehicle Brake Fluid (PM-20) or an equivalent DOT 4 LV (Low Viscosity) fluid. DOT 4 LV fluid is crucial for optimal performance of modern ABS and stability control systems, especially in colder temperatures. While DOT 3 fluid is technically compatible, DOT 4 LV offers a higher boiling point and improved cold-weather performance. Never use DOT 5 (silicone-based) fluid, as it is not compatible with systems designed for DOT 3 or DOT 4 and can cause severe damage to seals and ABS components. Brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point and can lead to corrosion in the brake system. It should be flushed and replaced according to Ford's recommended intervals, typically every two years or 30,000 miles.

Power Steering Fluid

For the 2017 Ford F-250 Super Duty, the power steering system requires MERCON® V Automatic Transmission Fluid. Similar to other fluid specifications, using the correct type is paramount. Do not substitute with power steering fluids designed for other vehicle makes or with other types of ATF. The fluid should be checked regularly and kept at the appropriate level. If the fluid appears dark or smells burnt, it's an indication that a flush and refill might be necessary. Consult your owner's manual for maintenance guidelines.

Washer Fluid

The windshield washer fluid reservoir should be filled with Motorcraft Premium Windshield Washer Concentrate (ZC-3-A) mixed according to instructions, or a high-quality, all-season pre-mixed windshield washer fluid. For regions with freezing temperatures, ensure the fluid has adequate freeze protection to prevent the reservoir, pump, and lines from freezing and cracking. The capacity is approximately 1.0 gallon (3.8 liters).

Diesel Exhaust Fluid (DEF)

For 6.7L Power Stroke diesel models, Diesel Exhaust Fluid (DEF) is essential for the Selective Catalytic Reduction (SCR) system, which reduces nitrogen oxide (NOx) emissions. The DEF used must meet the ISO 22241 standard (often indicated as API certified). Using incorrect or contaminated DEF can damage the SCR system, expensive to repair, and can even derate the engine's power. DEF has a shelf life and should be stored properly in a cool, dry place. The DEF tank capacity is approximately 7.5 gallons (28.4 liters). The vehicle's instrument cluster will provide warnings when the DEF level is low. Always refill with fresh, certified DEF from a reputable source.
