Capacity by Engine Option

Ford offered two excellent but very different engines for the 2014 F-350. Use this table to confirm the correct fluid and filter for your truck.

Oil Change Interval

Your 2014 F-350 is equipped with an Intelligent Oil-Life Monitor (IOLM) that will display a message when it's time for a change. However, your driving habits dictate the real-world interval.

• Normal Duty: For drivers who do not tow, idle excessively, or drive in dusty conditions, follow the IOLM, which typically recommends an interval of 7,500 to 10,000 miles.
• Severe Duty: This applies to most truck owners who tow, haul heavy loads, use their truck for construction or fleet purposes, or idle frequently. For severe duty, the interval should be shortened to 5,000 miles for the 6.7L diesel and 3,000-5,000 miles for the 6.2L gas engine to ensure maximum engine protection.

Drain Plug Torque

Properly tightening the drain plug prevents leaks and avoids costly damage to the oil pan. Always use a torque wrench.

• 6.7L Power Stroke Diesel: This engine uses a composite oil pan with a unique quarter-turn drain plug. The plug has a replaceable O-ring (Ford P/N 3C3Z-9N693-A) that should be inspected or replaced at each oil change. Torque to 19 lb-ft (26 Nm).
• 6.2L V8 Gas: This engine has a conventional steel oil pan. Torque the drain plug to 17 lb-ft (23 Nm). It is good practice to use a new drain plug gasket if available.

How to Change the Oil (Short Guide)

1. Warm the engine for 2-3 minutes to warm the oil.
2. Park on a level surface and place a drain pan under the oil plug.
3. Remove the fill cap from the engine to help the oil drain smoothly.
4. Remove the drain plug and allow the oil to drain completely.
5. Relocate the pan and remove the oil filter (it will be full of oil).
6. Wipe the filter mounting surface clean and apply a thin layer of new oil to the gasket of the new filter.
7. Install the new filter and tighten it hand-tight plus an additional three-quarter turn.
8. Reinstall the drain plug and torque it to the proper specification.
9. Fill the engine with the correct amount of new oil.
10. Start the engine, let it run for 30 seconds, shut it off, and re-check the dipstick, adding oil if necessary to reach the full mark.

Common Issues & Tips for This Generation

• 6.7L Power Stroke: Always use diesel-rated oil that meets the Ford WSS-M2C171-F1 (CK-4) specification. This is critical for protecting the complex turbocharger and modern emissions components like the Diesel Particulate Filter (DPF). Using the wrong oil can lead to expensive failures. The composite oil pan on this engine is durable but can be cracked by overtightening the drain plug—be extremely careful with torque.
• 6.2L Gas V8: Use a high-quality synthetic blend or full synthetic 5W-20 oil that meets the Ford specification to ensure proper lubrication and timing system performance. The oil filter is located on the front of the engine block and can be accessed from underneath, though it may be a tight reach.
