The 7.3 Powerstroke engine is arguably one of the best engines to be made by Ford. The longevity of this engine as well as its many applications is a testament to this fact.

Many would argue that it is one of, if not the best truck engines ever made. In this post, we are going to be looking into how many miles per gallon you can expect to get from it.

How Many Miles per Gallon Does a Powerstroke 7.3 Get?

The answer to this question depends on the type of truck you have, as well as how you drive it. That’s because there are several factors that can affect your MPG (miles per gallon) in any vehicle. Some of those factors include:

  • How much weight is being carried by your truck (cargo, passengers, etc.)
  • How fast you’re driving
  • What type of terrain you’re driving on (city/highway/offroad)

The best way to tell how many miles per gallon your 7.3 Powerstroke gets is to track its fuel economy over time so that you can see what it averages at different speeds, loads, and terrains. Powerstroke engine trucks are extremely durable and reliable.

Making them perfect for businesses needing to haul heavy loads over long distances. They also work well for families in need of a dependable truck that can carry extra heavy loads.

But, no matter what your use is or how much you love your Powerstroke, its MPG rating can fall short of expectations at times.

There are reasons behind this too, most notably the rating system. I’m sure you’ve heard that a 5/8th ton truck with a V8 can get around 20 MPG on the highway . . . but is that true?

On average, the MPG on a 7.3 Powerstroke ranges anywhere from 13.8MPG all the way to around 18MPG depending on the factors we’ve already talked about as well as whether the vehicle is loaded or not.

Is it possible to make your 7.3 Powerstroke more fuel efficient? And if so how can you do it? The answer is yes, it’s possible. But it takes a lot of work and careful planning to get the most out of your truck. We will be talking about these factors next.

How Can I Get Better Mileage Out of My Powerstroke 7.3?

There are a few things you can do to get better gas mileage out of your 7.3 Powerstroke engine, and we’re here to tell you about them! First, make sure that your truck is in good shape and well-maintained.

The more problems you have with your truck, the less efficient it will be. So, start by making sure everything is running smoothly. If you’re having trouble with something like brakes or suspension, bring it into a shop right away so they can get it fixed—and solve whatever issue is causing the problem.

Second, check your tires! Tires matter a lot when it comes to how much gas gets used up during your trip. If you’re running on bald tires or ones that are too worn down, they’ll use more fuel than they need to. Make sure all of your tires are deep in treads, if not, replace them! T

hirdly: keep an eye on your speedometer! Driving faster means using more fuel—so if you find yourself having to gun it off the line every morning just so you can get up to speed before lights change or traffic starts moving again… maybe consider slowing down a bit?

How Many Miles Will My Powerstroke 7.3 Engine Last?

But how many miles can you get out of a 7.3 Powerstroke engine? Well, that depends on how well you take care of it! If you keep up with regular maintenance like oil changes and tune-ups, you should be able to get around 300,000 miles out of your 7.3 Powerstroke engine before needing any major repairs or replacements (like rebuilding the engine).

If, however, you neglect these things or don’t know how to do them yourself—or even worse; if someone else does them wrong—then your mileage could be less than half that!

The 7.3 Powerstroke engine can last for about 500,000 miles if it’s well-maintained and serviced by a reputable mechanic. If you take care of the engine, you should be able to get between 400,000 and 600,000 miles on average.
