Understanding Semi-Truck Fuel Efficiency

With diesel prices rising, fuel efficiency is becoming more of a priority than ever, especially in the trucking industry. Commercial motor vehicles are not the most fuel-efficient rigs on the market. The average semi-truck gets about 6.5 miles per gallon (MPG), while a typical automobile receives about 25 MPG. However, minor changes can result in significant fuel savings over time, considering how many miles a long-haul trucker travels, which is often more than 100,000 per year. Read on to learn about semi-truck fuel efficiency and how you can improve yours.

What is Fuel Efficiency?

Fuel efficiency, measured in miles per gallon, describes how far a vehicle can travel with a certain amount of fuel. Motor vehicles with better fuel economy consume less fuel to drive the same distance as vehicles with poor fuel economy, reducing wasted fuel. Driving a fuel-efficient rig saves you money, reduces your carbon footprint, and lowers your vehicle’s dependence on oil. 

Tips For Improving Semi-Truck Fuel Efficiency

Truck drivers can take full advantage of a haul by being aware of their fuel mileage. Knowing how many MPG your semi-truck gets will minimize costs and improve travel and delivery time.


Follow these five tips to increase fuel efficiency in your semi-truck:

  1. Regulate Your Speed

Maintaining a consistent speed and avoiding major accelerations or decelerations will result in consistent fuel usage. For every mile per hour (MPH) increase above 55 MPH, semi-truck fuel efficiency reduces by 0.1 MPG. Additionally, accelerating from 0 to 65 MPH can use up to half a gallon of fuel. Keeping your speed consistent will help you avoid these two problems. Driving under 65 MPH will also improve your safety and that of other drivers on the road. 

  1. Use Cruise Control

Taking advantage of cruise control is another way to regulate your speed. Cruise control keeps your vehicle at a steady pace, saving you up to 6% in fuel consumption throughout your route. It is important to note that drivers should only use this function when road conditions are safe.

  1. Stay in a High Gear

Staying in one gear for as long as possible will also help improve your vehicle’s fuel efficiency. Aim to stay in top gear at least 85% of the time while on the highway. Additionally, make as few gear shifts as possible and maintain a revolutions per minute (RPM) range of 1250 to 1350.

  1. Reduce Idle Time

Avoiding idling when possible will help reduce wasted fuel as well. Every hour of idle time can burn a gallon of diesel and decrease your semi-truck fuel efficiency by 1%. It is best practice to shut the engine off if you plan to park for more than five minutes. Many companies have auxiliary power units (APUs) in their vehicles that allow you to maintain a comfortable temperature without idling. 

  1. Check Tire Pressure

Regularly checking your tire pressure is another good practice for not only improving your fuel efficiency, but also improving the safety of your vehicle and the lifespan of your tires. For a 10 pounds per square inch (PSI) drop in tire pressure, your vehicle’s mileage reduces by 1%. Under-inflated tires also generate more heat, causing them to weaken and eventually break. Make tire pressure checks part of your pre-trip inspection routine, and keep a gauge in your vehicle to check pressure while on the road.

Benefits Of Customizing Your Semi-Truck

Your semi-truck is your home away from home when you’re a truck driver, so you want it to be as safe and comfortable as possible. One of the advantages of being an owner-operator is having the freedom to set up your rig however you like. Even if you are a company driver, there are ways you can personalize your vehicle without making permanent changes. Customizing your semi-truck can be very beneficial, and we will discuss a few of the benefits in the blog below.


Five benefits of customizing your semi-truck include:

1. Feeling Comfortable in Your Rig

You will spend a lot of time in your vehicle as a trucker, especially if you are an over-the-road (OTR) driver. Truck customization can help you fight homesickness and make the long routes more comfortable. Bring along mementos like pictures of family members, friends, and events you cherish to remind yourself of home and motivate yourself while you’re on the road. Making cosmetic changes to your vehicle’s interior will also boost your comfort level. Consider replacing high-contact points, such as the steering wheel or shifter knob, with more ergonomic designs.

2. Improving Safety

Customizing your semi-truck can not only improve your comfort level, but it can also improve your safety. Changes like installing a light bar, custom LED lights, or a new navigation system make driving at night or in a new area a breeze. Another safety improvement you can make is tinting your windows. Tinted windows reduce sun glare and keep the interior of your vehicle cool during the hot summer months, all while upgrading your look.

3. Expressing Your Style

Another benefit of personalizing your rig is expressing your unique style. A new paint job or decals is one of the most popular ways to customize your semi-truck. When you turn your rig into a canvas, you will catch people’s eyes on and off the highway. Keep it simple with stripe detailing, or go all out with a custom paint job. Additionally, an added advantage of customization is that certain additions, such as a grille cover and chrome accents, can protect the exterior of your vehicle while also fitting your new paint style.

4. Encouraging a Healthy Lifestyle

Life on the road doesn’t have to be unhealthy. Installing interior electronics can make all the difference in staying healthy during long hauls. Customizing your cab with small kitchen appliances like a fridge or freezer, slow cooker, electric skillet, and two-burner stove allows you to enjoy home cooking while driving. These appliances can also decrease your stopping time, which in turn will improve your efficiency.

5. Getting Better Sleep

Healthy eating isn’t the only aspect of a healthy lifestyle. Getting enough sleep each night is also crucial to your well-being and safety while driving OTR. Upgrading your semi-truck with a personalized sleeping area can improve your sleep quality. Include items like a mattress pad, comfortable sheets and bedding, and a supportive pillow to help ensure you get high-quality sleep during long hauls.
