How to Increase Fuel Mileage on 6.7 Powerstroke

For many diesel owners, fuel mileage is a huge issue. Many face extensive fuel costs, which can lead to a highly unsatisfactory user experience.

With newer models entering the market, fuel mileage is continuing to get worse along with rapidly increasing fuel costs.

Therefore, if you have a diesel vehicle or the 6.7 Powerstroke, then you will agree that increasing fuel mileage has become essential. 

What is the Fuel Mileage of a 6.7 Powerstroke?

The 6.7 Powerstroke is a much-improved version of its predecessors. The 6.7 has better fuel mileage than previous versions since it features a single turbo boost, which is bound to keep its engine healthy and increase the MPG.

The engine is also compatible with biodiesel, giving you more versatile options to choose from. The 6.7 Powerstroke can provide you with 30 MPG on the highway and 22 MPG in the city. Combined, the engine has a fuel mileage of about 25 MPG. 

Does DPF Delete Increase MPG?

Based on a number of experiences of past users, removing the DPF from your engine can bring drastic changes to your MPG. DPF stands for diesel particulate filters. The major reason behind why and how DPF delete helps increase MPG is that it gets plugged with the residue from your fuel. When this filter gets plugged, the total mileage gets disturbed. It lets less fuel to pass through and therefore, increases the waste. As a result, when DPF is removed, fuel mileage is definitely increased. 

Will EGR Delete Increase MPG?

EGR stands for exhaust gas recirculation that is present in 6.7 Powerstroke engines. EGR aims to reduce nitrogen oxide emission in the air, and therefore brings these gases back into your exhaust. It often damages your engine and reduces its overall longevity. Removing or deleting EGR can therefore, not only help increase your MPG but also increase the longevity of the engine.

EGR delete kits are easily available at rather affordable prices. However, deleting EGR might not be as effective as deleting DPF. When you are planning on deleting EGR, make sure that there are no legal issues related to it, as in the U.S., the use of EGR delete kits is not legal in all states.

How to Increase Fuel Mileage on 6.7 Powerstroke

You can take some important steps to increase fuel mileage on the 6.7 Powerstroke engine. The following are easy, quick, and effective solutions to low fuel mileage:

Regular Maintenance of the Boost

For many people, boost is just entertainment or something unnecessary to the engine’s well-being. In reality, boost is imperative. The slightest issues in your engines are directly related to the need for maintenance in your boost. With high-quality boost that gets regular checkups, you can identify the slightest problems in very early stages before they become huge problems. Boost feeds power into the engine by forcing air into it. Without a proper boost gauge that functions effectively, your engine will not be powered properly. 

Performance Chips

By installing a performance chip in your engine, you can get started on not only increasing the mileage but also the torque and horsepower. Some of the best performance chips are manufactured by Ford, which are highly advanced and aren't inherently difficult to use. They are also highly adaptive.

The Pedals

An important issue that needs to be highlighted here is the force that we use to push the acceleration and brake pedals. The more force you use to push the pedal, the more power the engine will require, thus, consuming more fuel and energy. Pressing the brake pedals in the nick of the time is also a huge problem. It uses a lot of force and brings sudden changes to the engine’s functioning. Therefore, try to press the pedals with some ease and don’t push them to their limits. 

Benefits of Increasing Your Fuel Mileage

If you are not convinced whether it is worth it to take all the above-mentioned steps and increase your fuel mileage, here are some important benefits that might convince you.


Engines consume fuels that come from natural reserves, from where extracted oil is refined into various forms in oil mines. The more oil we extract, the more exhausted our natural reserves get. This means that after some years of extraction and consumption of natural resources, the earth will run out of them at some point.

Moreover, the more oil that is extracted, the more refining and factory processes take place. This increases the pollution emitted from heating and burning the oil to change it to other forms. As a consequence, there is a direct impact on the environment. If fuel economy is improved and there is an increase in the fuel mileage of engines such as the 6.7, we can help contribute to the betterment and protection of the environment. 

Longer-Lasting Engine

Better mileage also brings benefits to your car and its engine. Good mileage will ensure that your engine lasts longer, as the heat generated will decrease, leading to a much healthier engine. Moreover, parts like the ERG and DPF generate a lot of heat and reduce the life of an engine. Removing these can improve your mileage and also ensure a longer-lasting engine. 

Cost Savings

Better mileage means more cost savings. It means that your refueling will decrease over time, thus reducing fuel costs. Moreover, as mentioned above, increased mileage will also be good for the engine, so your repair and replacement costs will also decrease. Overall, increasing fuel mileage can also help your country’s economy, because as of now, only a few oil-rich countries are exploiting the situation and trading fuel for extensively high prices.


In conclusion, the 6.7 Powerstroke engine is a much better and an updated version of the previous Powerstroke engines. It was expected to offer better mileage but has very few improvements that do not significantly help middle-class truck drivers and other private vehicle owners. However, you can take important steps yourself by deleting the DPF, giving rest to your engine, and performing regular maintenance that includes checking your boost.

The benefits of improving fuel mileage are great and they not only benefit you but have a wide-ranging impact. Therefore, your small steps to increase fuel mileage in your 6.7 Powerstroke can prove to be highly significant and leave your pocket happier at the end of every month!
