So, as you can understand from the table above, the mileage of a 7.3 power stroke engine does not have a single spectrum. It can vary according to the use and tank type.

Since you have come this far, guess now you are more interested to learn more about this matter. So why is the delay for? Let’s dive into this further!

How Frequently Should Oil Be Changed In A 7.3 Power Stroke?

As you might easily conjecture, regular filter replacement and oil changes are essential for your 7.3 Power stroke engine to reach its mileage goal. However, to change the oil, you must replace the oil filter first.

Make sure you change the oil every 7500 miles. Also, do not forget to check the coolant of your engine. Now if you are wondering what part of your engine is the coolant system, the answer is, it is a colored liquid combined with water that keeps your engine from overheating in hot weather.

What Is A Fuel Filter?

When you want to talk about fuel, you must eventually come across an accessory named fuel filter. So,what is a fuel filter?

It is a filter in a fuel line that removes dirt & rust elements from the fuel. Almost all internal combustion engines contain these fuel filters.

Fuel filters play a crucial role in today’s sophisticated engine fuel systems. Unfiltered fuel might contain a variety of contaminants, such as rust brought on by moisture in a steel tank, paint chips, and debris that have been dragged into the tank during filling.

This will result in rapid wear and failure of the fuel pump and injectors if these substances are not removed before the fuel enters the engine. Fuel filters also increase performance since fuel may burn more effectively when there are fewer contaminants present.

Why Does Fuel Mileage Decrease? 4 common reasons

Everyone wants to make little gas station savings while still ensuring that their vehicle is operating at its peak efficiency. These two objectives come hand in hand when it is to fuel efficiency. There may be several causes if your overall gas mileage doesn’t seem to be how much you would like it to be.

It can be a mechanical problem or your driving style. Let me share with you some of the most common reasons behind low mileage.

#1. Mismatched Tire Pressure

Incorrect tire pressure not only destroys your gas mileage but also harms your tire alignment and tread. Underinflated tires produce additional traction, friction, and resistance. When this happens, to keep your tires moving, more gas is required as resistance increases.

#2. Fuel Supply

The amount of fuel that gets into the engine might be significantly impacted by a malfunctioning fuel injector or an outdated or unclean fuel filter. One of the most frequent reasons for poor gas mileage is an issue with the fuel system

#3. Air Filter Clogged

The paper or thin materials used to make air filters are fairly sensitive. So, as they wear down, they finally fill up with the dust and pollen they had kept out of the fuel system. Your engine can become suffocated by clogged air filters because they prevent proper airflow and this affects your mileage significantly. 

#4. Too Much Idling

You do not have to leave your car idle for so long when this is parked. Most cars only require 30 seconds or less to warm up during the morning, so there is no point in running your engine while you are waiting to be picked up or parked.If the engine is not necessary to run, turn off your car or keep it neutral.

These are the major reasons that are responsible for decreasing the mileage of your engine. There are some minor reasons as well namely faulty oxygen sensors, dirty or damaged spark plugs, faulty exhaust systems, inaccurate and old coolant sensors, etc.

Watch out for these signs in your automobile and fix them immediately once spotted. Follow the strategies described in the following section to increase the mileage.

How Can I Improve The Mileage Of My 7.3 Power Stroke?

This is one of the most frequent questions that I am queried. Since 7.3 power stroke is a pretty old version of the engine, it comes up with much less mileage than expected.

So to increase the mileage of your very own engine, I would ask you to follow the following steps-

Step 1:

Reduce the air resistance of your Ford. The better the aerodynamics, the better the fuel mileage.

Step 2:

Replace your Ford truck’s air filter with a new, superior one, and make sure that it stays clean. The engine uses less gasoline when it is exposed to more air.

Step 3:

Your truck should be as light as possible. Any unnecessary stuff should be taken out of the bed and cab. Installing bigger wheels and tires is not wise, nor are showy accessories such as chrome bars or extra lighting. They all will raise the truck’s weight and fuel consumption.

Step 4:

Make sure your tires are inflated properly. Uninflated tires will result in higher fuel usage. 

Step 5:

Follow proper driving practices. Do not let your engine warm up for any longer than necessary. Follow the posted speed restrictions and abstain from engine revving.

By following the above strategies, you can increase engine mileage to a great extent.

Frequently Asked Questions (FAQs)

1. Is The Mileage Of An Engine Constant?

Not actually. The mileage of a certain engine can increase and decrease. There are some follies of an engine such as clogged filter, faulty coolant, bad exhaustion and so on that cause a substantial decrease in mileage.

On the other hand, some steps like reduction of air resistance, tire inflation, and weight loss can result in a noticeable rise in mileage.

2. Are Odometer And Mileage The Same?

People often make this mistake. They are not the same.

Mileage and the odometer are two distinct things. An odometer is a device that records the distance traveled, while the mileage records the amount of fuel used each kilometer or mile. You can calculate mileageby using the distance you’ve driven.

3. How To Calculate The Mileage Of Your Car?

This is not much harder than a piece of cake. You canmeasurethe car’s mileage simply by finding the total distance you traveled from the trip meter and then dividing it by the consumed fuel amount.

Car mileage is calculated as follows: No. of kilometers/fuel consumed.Try it a few times to have a perfect reading of the mileage.

Take Away

So, after the above-elaborated discussion, now you are expected to have a panoramic idea of thefuel mileage of 7.3 Power Stroke. An automobile having a short tank can run up to 9-10 miles per gallon while new and 7-8 miles per gallon while old.

On the other hand, an automobile having a long tank can run up to 11-12 miles per gallon while new and around 9-10 miles per gallon while old.

Happy and safe driving!
