If you own a 6.7 Powerstroke truck, you must be concerned about your fuel mileage.

Most people experience high fuel costs, depending on their driving habits and the condition of the vehicle. This is particularly true for aggressive drivers and people who ignore timely maintenance like an oil change or tire pressure check. 

In today’s post, we will cover all the things you need for you to learn how to increase mpg for 6.7 Powerstroke.

Things like routine maintenance, good driving habits, deleting DPF and EGR, only braking when necessary, and installing the Powerstroke 6.7 performance module are among the items you’ll need to tick off your checklist.

What Is 6.7 Powerstroke?

6.7 powerstroke diesel engine

This is a 4-cycle diesel engine with a 6.7L displacement.

The 6.7 Powerstroke is uniquely engineered to meet strict emission standards. But most importantly, it is made to deliver high horsepower as well as torque over an extensive RPM range.

Why is 6.7 Powerstroke great? With this engine, you should expect big low rpm torque and exceptional weight reduction. You’ve also got lower noise, vibration and harshness compared to the 6.0.

How to Increase MPG for 6.7 Powerstroke

There are more than a few ways you can increase MPG for 6.7 Powerstroke. These include:

Regular Maintenance

One of the best things you can do to improve mpg for 6.7 Powerstroke is doing basic maintenance.

Always monitor your coolant because it can get more acidic over time. If the coolant is too acidic, it can rot the radiator, leading to poor fuel economy and expensive repairs.

Make sure you change your air filters in time because a clogged or dirty air filter could allow dangerous elements to reach the engine parts. You should also replace fuel filters regularly for optimal cleaning. Remember to make these changes every 10,000 to 15,000 miles.

The next important maintenance tip is timely oil change after every 5,000 to 8,000 miles, especially when towing or hard-driving. We suggest you use low viscosity oil, which can greatly reduce fuel consumption by approximately 4%.

Avoid Aggressive Driving

Aggressive driving can put a dent on your truck’s fuel mileage.

Not all drivers are created equal, so the bottom line can vary. Aggressive driving could cost you approximately $1 per gallon, which is an increase of up to 24% in fuel consumption. Sensible driving, on the other hand, can save more gas over time.

Never Leave Your Truck Idle

The more your truck is running the more fuel you are wasting. It is very important that you turn your truck off when you park it on the driveway.

Sometimes it seems to be more efficient to leave your truck running for a few minutes instead of turning it off than having to turn it on again. This assumption is false because it doesn’t take as much fuel to start your vehicle as it does to leave it on idle.

The only time you should leave your 6.7 Powerstroke idle is after a long heavy haul to let the vehicle cool down.

Lay Off the Throttle Pedal and Gradually Accelerate

There is no need to rev up your 6.7 Powerstroke engine before your truck switches gears. This can just lead to costly waste of fuel.

The faster you accelerate the more fuel you are using unnecessarily. Accelerating at a constant rate will greatly increase your mpg and improve your fuel economy.

Cruise Control Isn’t As Efficient As You Are

Cruise control is a unique system that holds your truck at a preset speed. It is usually convenient on faster roads and highways to take some pressure off the driver.

The controls you need to activate this feature are usually located on the steering wheel. It keeps your truck at a set speed and will do so until you deactivate the feature or press the brake.

Although cruise control is very convenient while driving along faster roads, it doesn’t know when you are approaching a hill or when there is traffic ahead. When driving the truck yourself, you have more control over when you want to lay off the throttle.

For example, when you are at the top of a hill, you can ride the hill without extra acceleration to save on fuel.

Only Brake When Necessary

You should only press the brake when necessary and not all the time. Staying a few miles per hour under the speed limit will prevent having to slow down for other vehicles on the road.

This will especially help increase mpg because you will not be constantly accelerating and decelerating. So, laying off the throttle sooner and coasting to stop is much more fuel-efficient for a 6.7 Powerstroke than accelerating and stepping on the brakes.

Install Powerstroke 6.7 Performance Module

If you are an average truck owner, you are likely to keep your truck for around 200,000 miles. Also, you may only be getting 15 to 16 miles per gallon.

If we set fuel prices at $3, wtih mpg of 15 miles per gallon, you could so easily spend approximately $40,000 on fuel for 200,000 miles. But you could effectively increase your mpg from 15 to 16 up to 18 to 19 miles per gallon by installing a performance module.

You will be able to save over $6,000 in fuel cost for a specific period.

A performance module is a little microcomputer that will take the signal coming out of your stock rpm. It will manipulate the signal to do what you want your truck to do based on the rpm and load of your engine. 

Most performance modules on the market are made to connect into your wiring harness with factory-style plugs. The best models have a dial that lets you choose a specific horsepower, such as 30, 60, or 90. We prefer using the 60 horsepower with a performance module to boost mpg.

In addition to increasing mpg up to 18 to 19 miles per gallon, a performance module gives you added horsepower. This product will help you go over steeper grades faster. You will also not have to worry about turbo lag.

DPF Delete

Diesel particulate filter (DPF) replaces the muffler as well as traps of the automobile exhaust system.

The DPF system does a good job of trapping soot, instead of releasing it into the atmosphere. It then oxidizes the soot with heat. So, what comes out of the exhaust is cleaner air. 

DPF delete, on the other hand, is the act of removing the diesel particulate filter. This has been reported to improve mpg for 6.7 Powerstroke.

Although we cannot claim by what value or number the mpg increases.

EGR Delete

The exhaust gas recirculation or EGR is a system in your truck that reduces nitrogen oxide emissions.

It is currently being used on both diesel and gasoline engines. In the case of the 6.7 Powerstroke diesel engine, the EGR is pretty efficient. When the exhaust gas is exiting the cylinders, a small fraction will return in the intake and will be burned again. This reduces nitrogen oxide emissions by up to 30%.

To increase your mpg and improve fuel economy, you may have to sacrifice the EGR system by deleting it from your truck. In addition to improved mpg, EGR delete could also lower engine temperature, reduce carbon deposit, reduce oil contamination, and improve throttle response.


How Many MPG Does Powerstroke 6.7 Get?

Most trucks running this type of engine when still new could hit mpg of 19 to 20 (the mpg could reach up to 22 on cruise control). But after 1,000 plus miles the mpg could reduce to 15 to 16. 

You can get better average mpg values with your truck if you exercise good driving habits and regular maintenance among other things.

How Long Can 6.7 Powerstroke Last?

Unlike the older models of the 6.7 Powerstroke, the newer ones are high-mile reliable and can last for more than 200,000 miles. 

If you stick with the manufacturer’s recommended service intervals, you could get up to 300, 000 or 400,000 miles out of this engine. Just make sure that you use high-quality fuel that is free of contaminants and air. Find out more about 6.7 Powerstroke longevity

Are There Any Benefits for Improved MPG?

Increased mpg is an indication that you are using less fuel to cover larger distances. This also means your fuel cost per annum could go down by up to $6,000 to $8,000.

Final Thoughts

Do you want to get your 6.7 Powerstroke mpg up and reduce your annual fuel costs by a significant amount?

Use the tips and tricks provided in this article to learn how to increase mpg for 6.7 Powerstroke. Most, if not all, of these things are easy to achieve like practicing good driving habits—avoiding aggressive driving and braking only when necessary—and regular maintenance among other things.

So, before stepping on the gas next time, think of what we have said if you truly want to keep those mpg numbers up.
