What is The Fuel Mileage of A 6.7 Power Stroke Engine?

From the table above, the 6.7 Powerstroke mileage is clearly better than that of other engines. However, several things affect the mpg, including where you’re driving.

The following are the mpg of the 6.7 Powerstroke engines in different conditions.

● Mileage on Highway

The 6.7 Powerstroke engine mpg on a highway ranges between 15 and 22, depending on the terrain and weather condition. With cargo, the highway mpg can drop to as low as 14 miles per gallon.

● Mileage in City

This 6.7 Powerstroke engine can have an average of 14.5 mpg when driving in a city. That is because driving in the city involves much stopping and going, affecting fuel economy. While towing, the engine can drop as low as 12 mpg.

● Fuel Use At Idle

The engine can consume between 4.5 and 5.5 gallons of fuel when idling. However, if you’re running the air conditioner or the car stereo, the usage can be more. The weather condition can also affect gas usage while idling.

What Factors Affect Powerstroke 6.7 MPG?

Comparing gas mileage can be challenging because it has so many variables that can impact it. The mileage differs significantly based on various factors. The following are some of the factors that affect Powerstroke 6.7 mpg.

#1. – Terrain

The terrain you drive the vehicle on also affects the mpg of your 6.7 Powerstroke engine. It burns much more fuel to climb on a steep slope than on a flat road. On mountainous terrain, some drivers reported a drop in mileage to as low as nine mpg.

#2. – Acceleration Habits

Speeding, hard revving and rough acceleration are all habits that affect your gas mileage. A driver who revs and accelerates hard may have reduced gas mileage at any terrain. Improved driving habits can improve fuel economy by 15% – 30%.

#3. – Wind Direction

Driving against the wind also decreases gas mileage. While this is not your choice, you can avoid cargo with poor aerodynamics to minimize drag. Wind can reduce mileage by about 13% for every ten-mph headwind.

#4. – Cargo Weight

Vehicles with 6.7 Powerstroke engines are used as utility vehicles. Despite their capabilities, overloading them can affect gas mileage. Overloading also affects other components like the DPF that clog much faster.

#5. – Regen

Regeneration is where the filter’s accumulated soot burns. During the process, the consumption rate increases by an average of 13%. The regeneration can affect the mileage on your Powerstroke engine.

#6. – Maintenance

The car’s condition affects its mileage. If it is in poor condition and has several failing parts, the engine will have to work harder to perform. Also, maintenance should be performed by qualified professionals.

There are known 6.7 Powerstroke Fuel Filter Change Problems you can avoid by letting a mechanic do it for you. Also, the engine’s condition matters and should be in tip-top shape for better mileage.

How to Increase Fuel Mileage on 6.7 Powerstroke?

With the cost of gas increasing daily, heavy-duty engines like the 6.7 Powerstroke engine can be costly to keep on the road. However, there are various ways you can increase gas mileage. They include:

1. Improve Driving Habits: keep speeds below recommended and avoid hard acceleration.

2. Avoid Steep Terrain: When planning for your trip, avoid roads with steep terrain.

3. Avoid Short Trips: Short trips cost double the fuel consumed compared to a single trip.

4. Keep Cargo Weight at a Moderate: Avoid overloading by keeping the cargo below the maximum towing capacity.

5. Delete EGT: Removing Exhaust Gas, which helps increase gas mileage. However, be aware of the 6.7 Powerstroke EGR delete problems that may develop.

6. Delete DPF: Deleting Diesel Particulate Filters also increases gas mileage.


The following are the frequently asked questions about the 6.7 Powerstroke engine. The answers are well-researched to satisfy your questions.

Are 6.7 Powerstroke Engines Reliable in Terms of Mileage?

Yes. Of all the Powerstroke engines, the 6.7L is the most reliable one. Mainly it’s because it features a single Turbo boost, which increases its mileage. However, your driving style will contribute to gas mileage reliability.

Is it Expensive to Run The 6.7 Powerstroke Engine?

Like most heavy-duty engines, the 6.7 Powerstroke engines are more costly to run. With an mpg between 12 and 22, and a fuel price of $3.5 per gallon, a 100-mile trip will cost about $23.

Does Removing DPF Increase the MPG Of My 6.7 Powerstroke Engine?

Yes. Removing the Diesel Fuel Particulate can increase the gas mileage on your 6.7 Powerstroke engine. The DPF is prone to clogging by the fuel residue, limiting the amount of fuel passing.

Key Takeaways:

This piece addresses the major aspects surrounding 6.7 Powerstroke fuel mileage. It also helps you know the various factors that affect the gas mileage. Below are the key highlights of the article:

  • The 6.7 Powerstroke engine fuel mileage averages at 17 mpg.
  • Maintenance, cargo, driving habits, and terrain affect the mileage.
  • Improving driving habits can improve fuel economy by more than 15%.
