How to Increase Fuel Mileage on 6.7 Powerstroke? (My Best Tips)

Fuel is a natural resource. Therefore it makes sense to save as much as possible by increasing your vehicle’s fuel mileage. Ideal fuel mileage provides several benefits, such as saving on expenses and reducing carbon footprints. Moreover, it keeps your engine well and enhances its life.

As you’re reading this article, I am assuming that you already own a 6.7 powerstroke engine. I also own it, and it’s undoubtedly one of the best engines of current era. However, it’s important to learn how to increase fuel mileage on 6.7 powerstroke.

Because, an increased mileage cuts down your cost of refueling. In addition, it also brings down the number of visits to petrol stations for refueling. Both these factors contribute to saving your money and time significantly.

How to increase fuel mileage on 6.7 Powerstroke

Fuel comes from crude oil and undergoes various refinement processes before it can be used. All these processes contribute to pollution. So the more we optimize fuel usage, less we pollute the planet. It will be a baby step towards protecting the environment.

And lastly, who wants to put in money to buy a new engine prematurely? An increase in mileage keeps the engine cool, increasing its lifespan.

The easiest way to increase fuel mileage is to avoid the following:

  1. Rash driving
  2. Extreme idling
  3. Driving at higher speeds
  4. Paying attention to the meters on the dashboard

This article may help you know how to increase fuel mileage on 6.7 Powerstroke.


How to increase fuel mileage on 6.7 Powerstroke? (The Actual Guide)

Your vehicle is one of the assets, having several sub-assets. Fuel is one of the assets which you should use optimally. With a disciplined approach, it is not at all difficult to achieve ideal fuel mileage.

Let’s dive in further to understand in a more detailed way.

Monitor and maintain the engine

The first step towards achieving the goal of increasing mileage starts with taking care of the engine. Regular cleaning/replacing the air filter, changing the oil, and regular check-ups on the transmission system will keep the engine clean and healthy. 

Monitor and maintain the engine

It will reduce the load on the engine. A loaded engine will demand more fuel. Regular engine maintenance enables you to tackle any problem in the initial stages. Referring to your owner’s manual will help you to understand to maintain the engine systematically.

Pay attention to tire pressure. Incorrect tire pressure may hamper your vehicle’s performance. More energy will be required to drive, which the engine ultimately will derive from the fuel.

Reduce unnecessary weight

Unload all the unnecessary stuff from your vehicle. Try running freely, and then try running carrying something. What exhausts you more? The latter, right? Because you need more energy when you are loaded with something. 

The same goes with vehicles too. It will procure more energy to drag along with all the loads stacked in. Extra fuel is consumed to match the energy required to carry the load. Therefore, removing unnecessary things from your vehicle is essential, making it a bit lighter.

Use the correct fuel for the engine

The manufacturer recommends a specific fuel for your vehicle’s engine. It is to benefit you by having an efficient driving experience and keeping the engine and other parts clean. 

Use the correct fuel for the engine

The correct fuel also benefits you with good mileage. Fuel not recommended by the manufacturer may result in poor engine performance and decreased mileage. In addition, your vehicle will emit more toxic gases, increasing the pollution percentage in the environment.

Use cruise control when appropriate

Achieving better mileage on highways is not difficult at all. You can accomplish it by switching to cruise control to drive at a maximum of 55 miles/hour or less. Manual driving may tempt you to overtake other vehicles- resulting in driving at high and low speeds.

Use cruise control when appropriate

The speed variations hamper your fuel economy. Even in traffic, avoid rapid acceleration or emergency brakes. Being calm at the steering wheel will bring down fuel consumption significantly.

Drive efficiently

Every other driver will tell you about his/her driving efficiency. But is it true? We unknowingly drive rashly, which includes aggressive acceleration, urgent brakes, not paying attention to the dashboard gauges, etc. 

Efficient driving comes with a lot of discipline. Be gentle with your vehicle. Avoid sudden speeding and braking. Keep a close eye on the RPM gauge and prevent it from entering the ‘red’ section.

Drive efficiently

While speeding, avoid pressing the accelerator hard. Go smoothly with it; gradually press it to gain the required momentum. The same goes with brakes too. Sudden speeding and braking bring down the mileage. It will also harm the vehicle’s body and other parts.

Ensure your RPM needle stays in the lower part of the gauge. Following all the above will help you to increase your vehicle’s mileage.

Vehicle modifications

A few modifications will help you with better mileage. Let’s look at them in short.

Vehicle modifications

Aerodynamic body modifications

Completely modifying the vehicle body is out of the question. The cost might be the same as purchasing a new vehicle altogether. Herewith are a few tips to help you with that.

  • Remove roof racks if any
  • Front bumpers and wheel arches to be aerodynamic
  • Lower the suspension

These minor modifications will improve the MPG. However, the vehicle’s make and model do matter. 

Ideally, you can consult with a professional before implementing these changes. In addition, discuss with insurance consultants and your dealers to understand what modifications can void your vehicle’s warranty.

Eco-friendly tires

Eco-friendly tires are known to have low rolling resistance. A tire having low rolling resistance is crucial for fuel economy. It saves about 20% fuel, offering additional benefits such as a good grip on the road with less noise.

Synthetic oil

Synthetic oil doesn’t break down quickly, helping to keep the engine clean. Better lubrication and decreased wear and tear lead to enhancing the mileage.

Use lightweight parts

Replace steel or alloy metal parts with carbon fiber or lightweight materials. After every 50 kgs of weight, you can save about 2% of fuel.

Maintain Tire Pressure

Incorrect tire pressure may lead to poor mileage. The vehicle will require more energy to drive, ultimately wasting fuel. A tire with appropriate pressure help in better road grip and better mileage.

Install a Cold Air Intake

Cold air intake provides more air to the engine. A cooled engine will provide more energy in the same amount of fuel. Moreover, it saves you from adding a more intense air filter. 

Install a Fuel Limiter

A fuel limit enhances the throttle response and decreases the lag. It helps to provide the appropriate power to drive your vehicle in the usual way.

Enhancing the mileage of your vehicle solely depends on your driving habits. Driving to increase mileage will help you to maintain the required discipline. Avoid aggressive speeding and emergency brakes.

On the highways, leave the cruise control to take care of the driving. In traffic, try not to rush with sudden acceleration and brakes. Keep a tab on all the gauges on the dashboard.

Try to keep the RPM needle at the lower side most of the time. Regular check-ups and routine maintenance, using recommended fuel and oils, will keep the fuel consumption on the downside.
