6.7 Powerstroke Oil Capacity(+ Best Recommended Oils)

Using the correct amount of engine oil is critical. Too little oil can cause excessive wear and overheating, while too much oil can lead to foaming, increased crankcase pressure, and damage to engine seals.

This guide covers oil capacity by model year, oil specifications, and maintenance tips to keep your 6.7 Powerstroke running strong.

6.7 Powerstroke Oil Capacity

The Ford 6.7L Powerstroke diesel engine has an oil capacity of 13 quarts (12.3 liters) with a filter change, which applies to most 2011–2024 Ford Super Duty trucks, including the F-250, F-350, F-450, and F-550.

Ford recommends using SAE 10W-30 diesel engine oil meeting WSS-M2C171-F1, with 5W-40 full synthetic as an acceptable alternative for cold climates or heavy towing, and the oil level should always be verified using the dipstick after refilling.

Ford 6.7 Powerstroke Overview

The 6.7L Powerstroke is a turbocharged V8 diesel engine designed and built by Ford. It replaced the 6.4L Powerstroke and has gone through several updates since its launch, including improvements to fuel injection, turbocharging, and emissions systems.

Key features include:

Cast iron block with aluminum heads
High-pressure common-rail fuel system
Variable geometry turbocharger
Advanced emissions equipment (DPF and SCR)

Because this engine works under high loads and temperatures, proper lubrication is essential.

6.7 Powerstroke Oil Capacity by Model Year

Although the engine design has evolved over time, the oil capacity for the 6.7 Powerstroke has remained fairly consistent across most model years.

Standard Oil Capacity

For most Ford Super Duty trucks equipped with the 6.7L Powerstroke:

Oil capacity with filter change: 13 quarts (12.3 liters)
Oil capacity without filter change: Slightly less, but a filter change is always recommended during service

This capacity applies to the majority of 2011–2024 Ford F-250, F-350, F-450, and F-550 Super Duty trucks with the 6.7L diesel engine.

Important Note on Variations

While 13 quarts is the factory specification, small variations can occur due to:

Oil cooler and system drainage differences
Aftermarket oil pans
Incomplete draining during oil changes

Always verify the oil level using the dipstick after refilling.

Recommended Oil Type for the 6.7 Powerstroke

Using the correct oil type is just as important as using the correct oil capacity.

Factory-Recommended Oil Viscosity

Ford recommends:

SAE 10W-30 diesel engine oil (preferred)
SAE 5W-40 full synthetic (acceptable, especially in colder climates)

The oil must meet Ford WSS-M2C171-F1 specification.

Why 10W-30 Is Preferred

Ford transitioned to recommending 10W-30 for most operating conditions because it:

Improves fuel economy
Provides excellent protection under heavy loads
Performs well in a wide temperature range

5W-40 is still widely used, especially for towing, extreme heat, or cold-weather starts.

Oil Change Interval for the 6.7 Powerstroke

Ford uses an Intelligent Oil Life Monitor (IOLM) to determine oil change intervals based on driving conditions. However, many owners prefer fixed intervals for peace of mind.

Typical Oil Change Intervals

Normal driving: Every 7,500–10,000 miles
Heavy towing or severe duty: Every 5,000–7,500 miles
Fleet or commercial use: Follow oil analysis or stricter schedules

Always reset the oil life monitor after an oil change.

How to Check Oil Level on a 6.7 Powerstroke

Checking the oil level correctly ensures the engine is neither under-filled nor over-filled.

Steps to Check Oil Level

Park the truck on level ground
Allow the engine to cool for at least 10–15 minutes
Remove the dipstick and wipe it clean
Reinsert the dipstick fully
Remove again and check the oil level

The oil should fall between the MIN and MAX marks. If it is above the maximum mark, drain excess oil to prevent engine issues.

Consequences of Incorrect Oil Capacity

Running the wrong oil level can cause serious problems.

Too Little Oil

Increased engine wear
Poor lubrication of the turbocharger
Higher operating temperatures
Risk of engine failure

Too Much Oil

Oil aeration and foaming
Increased crankcase pressure
Oil leaks and seal damage
Potential DPF and emissions issues

Always aim for the factory-recommended 13 quarts and confirm with the dipstick.

Best Practices for 6.7 Powerstroke Oil Changes

To get the most life out of your engine, follow these tips:

Always replace the oil filter during oil changes
Use high-quality diesel-rated engine oil
Allow sufficient drain time to remove old oil
Do not rely solely on oil quantity – always verify the level
Consider oil analysis for high-mileage or hard-working trucks

Regular maintenance goes a long way in extending engine life.

FAQ

How many litres of oil does a 6.7 Powerstroke take?

A Ford 6.7L Powerstroke diesel engine takes approximately 12.3 liters of engine oil (13 quarts) when the oil filter is replaced, which is the standard procedure during an oil change.

What oil is recommended for a 6.7 Powerstroke?

Ford recommends SAE 10W-30 diesel engine oil that meets the Ford WSS-M2C171-F1 specification. This oil provides the best balance of protection, fuel economy, and performance for most driving conditions.

Can I use 15W-40 in my 6.7 Powerstroke?

Yes, 15W-40 can be used, especially in warmer climates or for older engines, but it is not Ford’s preferred viscosity. It may result in harder cold starts and slightly reduced fuel economy compared to 10W-30 or 5W-40.

Should I use 10W-30 or 15W-40 in my 6.7 Powerstroke?

For most owners, 10W-30 is the better choice because it improves fuel efficiency and provides excellent protection across a wide temperature range. 15W-40 is better suited for consistently hot environments or severe-duty use but is less ideal in cold weather.

What happens if you overfill a 6.7 Powerstroke with oil?

Overfilling the engine can cause oil foaming, increased crankcase pressure, seal leaks, turbocharger issues, and potential damage to emission components. Always verify the oil level with the dipstick and drain excess oil if it exceeds the maximum mark.

How many liters is a 6.7 Powerstroke?

The 6.7 Powerstroke refers to the engine’s displacement, which is 6.7 liters, not the oil capacity. This measurement represents the total volume of all engine cylinders combined.

Final Thoughts

Understanding the correct 6.7 Powerstroke oil capacity is a key part of proper diesel engine maintenance. With a standard capacity of 13 quarts, using the correct oil type and maintaining regular oil change intervals will help ensure optimal performance, fuel efficiency, and long engine life.

Whether your truck is used for daily driving, towing heavy loads, or commercial work, sticking to Ford’s oil specifications and best practices will keep your 6.7 Powerstroke running strong for hundreds of thousands of miles.
