Understanding Different Fuel Types for Construction Equipment: A Guide

Updated: Jan 6

The job site: it’s not just about bricks and mortar. It's about the mighty machines that lift, dig, move, and do the heavy-duty work to make everything happen. And guess what powers these hulking metallic beasts? That's right, it's fuel. But here's the thing, not all fuel is created equal. The fuel needs of a skyscraper-bound crane differ from those of a down-in-the-dirt excavator. So, let's delve into this high-octane world and understand different fuel types for construction equipment. It's an art, a science, and a bit of a magic show, all rolled into one.

The future of fuel delivery is here.

The Power Behind Your Construction: A Deep Dive into Fuel Types

Fuel is the unsung hero of the construction world. It's the force that keeps our machinery running, our projects advancing, and our visions transforming into reality. Yet, when it comes to fuel, many of us don't go beyond the basics. As long as the tank is full and the engine is humming, we're good to go, right?

Not quite. The type of fuel you use in your equipment can significantly impact your project - from cost efficiency and equipment lifespan to environmental footprint. In an industry where every minute and dollar counts, it's high time we understood our fuel choices better.

So, whether you're a seasoned construction veteran or a newcomer to the field, this guide is designed to demystify the world of construction fuels. We'll delve into the pros and cons of different fuel types and explore how to make smart, informed decisions that not only benefit your project but also the planet.


Diesel: The Undisputed King of Construction Fuel

Think construction. Think diesel. The Energy Information Administration (EIA) states that diesel accounts for a whopping 60% of the fuel used by the construction industry. The reasons? High energy content, efficiency, and durability.

Diesel packs a punch, offering more energy per gallon than gasoline. This high energy content means your machinery can run longer on a single tank of diesel. Plus, diesel engines are built tough. They're engineered to withstand the heavy loads and rugged conditions of a construction site.

Remember this: diesel comes in two forms - on-road (clear diesel) and off-road (red diesel). The latter is for non-road vehicles like excavators and bulldozers and is dyed red to distinguish it from on-road diesel. Red diesel is also tax-exempt, making it a cost-effective choice for construction projects.

Gasoline: Not Quite the Underdog

Gasoline might not be the first fuel that comes to mind for construction, but it still plays a role. Some lighter equipment, such as portable generators and small, mobile machines, run on gasoline.

The EIA reports that gasoline fuels about 17% of construction industry equipment. It's less energy-dense than diesel, but it's highly volatile (which means it ignites easily), making it suitable for small engines that need to start quickly.

Propane: The Cleaner, Greener Option

Ah, propane! It's the fuel that keeps on giving. Propane-powered equipment emits fewer harmful pollutants than diesel or gasoline engines. That's why it's often considered a greener fuel choice.

According to the Propane Education & Research Council, propane-powered forklifts produce 19% fewer emissions than their gasoline counterparts and a significant 7% less than diesel. Propane also has the edge when it comes to maintenance. Propane burns cleaner, which means less engine residue, fewer oil changes, and lower maintenance costs.

Natural Gas: The Emerging Contender

Now let's talk about a fuel type that's relatively new to the construction scene but is steadily gaining ground: Natural Gas. This fuel type has traditionally been used for heating, cooking, and electricity generation. However, it's beginning to show promise in the construction industry, particularly as a fuel for heavy-duty trucks.

Natural gas is plentiful and domestically produced, which can lead to cost savings, especially when gasoline and diesel prices skyrocket. The U.S. Department of Energy also highlights that natural gas vehicles have generally lower emissions compared to their gasoline and diesel counterparts. The cherry on top? Natural gas distribution infrastructure is well-developed, making refueling as convenient as traditional fuels.

However, natural gas isn't without its challenges. Retrofitting equipment for natural gas can be pricey. Plus, natural gas has a lower energy content than diesel, meaning more frequent refueling for heavy-duty equipment. But keep an eye on this space - technological advancements may soon make natural gas a serious competitor in the construction world.

Biofuels: Pioneering a Sustainable Future

Biofuels have been the buzzword for a while now, especially in the sustainability circuit. Made from organic matter like corn, soybeans, and even used cooking oil, biofuels are renewable and can significantly reduce carbon emissions. According to the Renewable Fuels Association, biodiesel reduces greenhouse gas emissions by 46% compared to petroleum diesel.

While biofuels may not yet be mainstream in construction, they represent an exciting opportunity for the industry to reduce its carbon footprint. Biofuels are compatible with most diesel equipment, making the transition easier. However, biofuel blends can be more expensive than traditional fuels, and their availability can be limited. But as governments push for cleaner energy, we can expect biofuels to become more accessible and affordable.


In the end, fuel choice boils down to the specific needs of your project and the machinery you're using. Each fuel type has its pros and cons, from cost and efficiency to emissions and availability. Understanding these nuances can help you optimize your operations and even save some dollars in the process.

Whether you're a fan of the old faithful diesel, or you're ready to venture into biofuels or natural gas, remember this: fuel isn't just something you pump into a tank. It's the lifeblood of your operation. It's the power behind every dig, lift, and transport. So give it the thought it deserves.

The future of construction is not just about building structures; it's also about building sustainability and efficiency. And that starts with the fuel in our tanks.
