How to Maximize Diesel Engine Efficiency

Did you know that 70% of U.S. freight is transported by Class 8 trucks? Whether you’re transporting oil, food, or another commodity, you need to increase your diesel engine efficiency as much as possible. 

Especially now, with diesel prices on the rise, truckers are feeling the pinch across the country. You might wonder how to increase the efficiency of your diesel engine. Read this guide on how to maximize it to ensure to go farther and save your cash. 

Lower Your Highway Speed

Did you know that diesel fuel lets you take longer trips than gasoline? A full tank can take you between 400 and 800 miles. Engines can normally receive between 45 and 50 MPG.

While this is the case, you’ll still want to watch your speed.

It’s tempting to race to your next destination, but that’ll burn through your diesel fast. When you’re on the highway, drop to a slower speed. When you go over 55, you’re burning more diesel. 

Check Your Tires

When cutting back is the goal, check your tires. Over or under-inflated tires can decrease your fuel mileage. 

Even if you checked it, changes in air temperature can impact your tires. They can decrease when it’s cold and increase when it’s hot. Use the tire manufacturer’s suggested psi whenever possible. 

Vehicle Monitors

Consider installing a monitor to have better fuel mileage. It’ll let you know how many miles per gallon you’re receiving.

You’ll be able to know whether you’re driving too fast, at an inconsistent speed, etc. 

Use Engine Parameter Settings

Use them for better mileage and fuel efficiency. Review them over time and use cruise control whenever possible. Cruise control will allow you to avoid using the throttle to climb hills. 

You’ll also want to keep your equipment well maintained. This will ensure that it’s working properly and giving you accurate measurements.

Air Filters & Air Intake

Use an advanced air intake system to keep your engine working like new. This will allow you to avoid losing power. Inadequate airflow can lead to a loss of power. 

Go with premium air filters. While they’re expensive, they’ll offer you a higher fuel advantage. 

Use High-Quality Fuel

Head to high-traffic filling stations that have diesel moving in and out all day. Avoid places that seem quiet, diesel that sits decreases in quality over time. 

This will help to increase the life of your injection and injector pumps. You’ll want high-quality fuel since these aren’t inexpensive to replace. 

Some truckers will choose smaller storage tanks. This will keep your current diesel stock fresher and lasting longer. 

If not, moisture and bacteria could build up over time. You’ll also want to perform proper maintenance on your tank to keep it in good condition. 

Upgrade the Exhaust

Your diesel performance is tied to your exhaust system. Consider using an exhaust system with a large capacity. 

This will give you more horsepower. You’ll be able to expel more exhaust over time. Your truck will be able to reach a balance due to this. 

Upgrade Diesel Fuel Injectors

Enjoy a stronger power output when you use fuel injectors. They could increase your horsepower as well. They have a hole pattern to help maximize the delivery that your truck will receive. 

Extra Additions

Before you buy any additions to your truck, be sure that it’s necessary. While some will buy fuel additives because of the promise of fuel efficiency, speak with a mechanic. 

If you’re a part of a team, make sure that everyone is up-to-date on this various information. Speak with them about how to save fuel and consider hiring aids to educate your drivers. 

Various Tips

Don’t rev the engine when you drive since it’ll burn your fuel. Don’t idle whenever possible; this will also kill the fuel. 

Try to predict when a traffic light is coming. When you avoid taking a complete stop, this will help to preserve the fuel economy. 

Keep a safe distance from the cars in front of you in case they stop suddenly. The further back you are, the less likely you are that you’ll have to stop fast. 

How Can I Make My Diesel Engine Last Longer?

While diesel engines tend to last for a long time, proper maintenance is necessary. First, change the oil on a regular basis. Fuel filters will also help. 

Stick with factory parts and use quality fuel. Certain devices such as DPFs, EGR coolers and valves, and SCR/DEF systems can cause problems. Speak with your mechanic to see your best option. 

While these systems can reduce exhaust emissions, they can also reduce your mileage. Consider delete kits since they can remove these from your system. 

Have oil changes based on the recommended mileage interval. Use the correct filter and oil. 

Even time sitting idly can burn your gas, not just when you’re on the move. If you’re often idle, factor that into how often you should change your oil. If not, you could have higher engine hours and not know it.
