How to Increase 7.3 Powerstroke MPG – Informational Guide

Choosing a good engine for your vehicle is very important; we can all agree with that. However, having a sustainable way to run that engine is also equally important. Engines like the 7.3 Powerstroke are great, but to make the most out of them, you need to focus on the fuel economy as well.

Moreover, diesel can be expensive, so that is another reason to pay attention to the MPG (miles per gallon) capacity of your engine.

To help you out with that, we have made an easy informational guide on how to increase 7.3 Powerstroke MPG. So without further ado, let’s get down to business.

8 Basic Steps to Increase the Fuel Economy and Mileage

To make understanding easier, we have broken down the entire process into eight simple steps. These are in no particular order, but each one is important if you want to increase the fuel economy and mileage of your engine. 

1. Maintenance

Although this may seem pretty obvious, it is extremely vital. If each and every part of your vehicle is well maintained, it will deliver to its full potential. Be sure to never miss out on your oil changing date. With time, oil tends to become like sludge and loses its lubricity.

This could lead to an adverse effect on your gears and cause extra drag. Apart from that, be very particular about having clean air filters and fuel filters. The reason for this is that if your filters are not clean or are clogged up, they will have a direct effect on the horsepower. You may even end up losing around 15-50hp. 

2. Lubricate Generously

This is another step you do not want to skip. Remember, when you lubricate your machinery well, it only works out for the best. If we compare a lubricated engine to one that is not properly lubricated, we will immediately notice the stark differences in the performance.

It is easier for a lubricated engine to move the pistons. This is because there is less friction, and the pistons just glide smoothly. Obviously, when less effort is needed, that means less fuel is used to make the engine work, and just like that, you have a more efficiently functioning engine. 

3. Check Your Boost

Although boost gauges are considered unimportant by many, it can serve as a great way to keep your engine in check. Think of your boost gauge as a radar that will help you catch on to the little issues before they turn into big problems. If you happen to be losing boost pressure, know that there is something going on with your engine. Of course, the nature of the problem could vary, but sure enough, a problem will be there. It could be a dirty filter or a leak in the exhaust pipes, etc. However, if you keep an eye on your boost level, these problems will never go unnoticed. 

4. Enlarge Your Exhaust

Enlarging your exhaust system, especially the pipes, will help a lot. A good exhaust system is really vital to good performance. It makes sure that no unwanted gases produced from the combustion cycle are left behind. Typically, manufacturers do not put a lot of focus on this aspect, and you are provided with narrow exhaust pipes that have sharp bends.

This makes it harder for the gases to leave. In consequence, more fuel is used to push the gases out. A wider exhaust will make it easier for the gases to exist, and ultimately less fuel will be used. 

5. Check Your Tire Pressure

Tire pressure is another factor that can contribute to increasing MPG. So how does tire pressure add to better fuel economy? Well, research has shown that in some cases, you can increase MPG up to 3% with tires that are properly inflated. That is because properly inflated tires need less fuel to move. Since they will also be balanced, moving the vehicle will need less energy in general. Apart from that, properly inflated tires are much safer than those that are not. If you want to find out the optimal tire pressure for your vehicle, look in the owner’s manual or even online. 

6. Replace the Cold Air Intake

Adding a cold air intake filter to your vehicle will increase its performance, without a doubt. In fact, some cases have shown that it is has managed to increase the performance of an engine by 5-20 horsepower. It helps keep your engine cleaner and allows it to work more efficiently. However, to maintain that, this filter also needs to be changed on time, like any other filter. In fact, if this filter is clogged or is not changed when needed, it could cause an opposite effect on your engine. 

7. Turn Off the AC

When the weather is pleasant enough, and the air conditioner is not needed, then turn it off. Using the AC unnecessarily eats up more fuel than you can fathom. If you start regulating the use of the AC in your vehicle, you will notice a difference in the fuel cost. Avoid using your AC on full blast, especially when you are traveling for long distances. This is because when your car is heated, the AC works harder, and when it works harder, it eats up more fuel. The environment inside the truck can be kept pleasant without using the AC on full blast. In fact, it is best to use AC for limited time intervals. 

8. Add a Tuner Chip

Tuner chips can also help out with improving MPG. A chip can regulate many aspects, such as optimizing air to fuel ratios. This makes it easier to figure out what you need to do to keep your vehicle running in the best possible condition. It also has other features, such as mapping to provide a flatter torque curve, which ultimately allows for better and more efficient fuel consumption. A tuner chip is a fantastic piece of technology, which, when used properly, can be very beneficial to your vehicle overall.


Increasing your MPG and fuel economy is not all that difficult. Even the steps discussed in this guide are very easy and most are related to the routine check-ups of a vehicle. You need very little equipment to make a difference in your fuel economy. All you really need to do is keep an eye out for minor problems and make sure that the vehicle is always well maintained. So, remember not to take the little things lightly, and you will be good to go!
