Diesel vs. Gas Commercial Trucks: What’s Right for You?

When purchasing commercial trucks, you have to consider many factors, including the type of fuel that powers the vehicle. Diesel and gas are the two most common fuel types in commercial trucks.

Both have advantages and disadvantages, and choosing the right fuel type is critical to getting the best performance, fuel efficiency, and cost savings. Let’s look at diesel vs. gas commercial trucks and help you decide which is right for your business.


One of the most significant differences between diesel and gas commercial trucks is their engine performance. Diesel engines are more powerful and torque than gas engines, which can handle heavier loads and steep hills more easily. In contrast, gas engines are more lightweight and refined, ideal for shorter and lighter hauls. A diesel truck would be a better choice if you have to transport heavy loads over long distances.

Fuel Efficiency

Fuel economy is another critical factor when choosing between diesel and gas commercial trucks. Diesel engines are more fuel-efficient than gas engines, which translates to a lower cost of ownership over the vehicle’s lifespan. Diesel engines require less fuel to cover the same distance as a gas engine, thanks to their higher compression ratio and more efficient combustion process. If you want to save on fuel expenses long-term, go for a diesel truck.

Maintenance Costs

Another important aspect to consider is the maintenance costs of diesel vs. gas commercial trucks. Diesel engines are built to last longer and have fewer moving parts than gas engines. They also have better lubrication properties, requiring less frequent oil changes. However, diesel engines are more expensive to repair and maintain than gas engines. Gas engines are generally more affordable to service and have more accessible repair shops than diesel engines. Use gas-powered vehicles if you have a limited budget or want easy-to-maintain trucks.

Environmental Impact

Nowadays, environmental concerns are a vital consideration when selecting any vehicle. Diesel engines have come a long way in reducing emissions, thanks to advanced technologies such as diesel particulate filters and selective catalytic reduction. However, they still emit more pollutants, such as nitrogen oxides and particulate matter, than gas engines. Gas engines have lower emission levels and are considered more environmentally friendly. A gas-powered truck would be a better choice if you want to reduce your carbon footprint and meet strict emissions regulations.


Lastly, the upfront cost of buying a diesel vs. gas commercial truck is a significant factor. Diesel trucks are generally more expensive to purchase than gas-powered trucks. They are also more expensive to fuel and maintain. However, diesel engines have a longer lifespan, so they can recoup their initial investment over time. Gas trucks are cheaper to buy, fuel, and maintain but have a shorter lifespan than diesel engines. If you have a limited budget and do not need high-performance or long-haul capabilities, go for a gas-powered truck.

Choosing between diesel and gas commercial trucks depends on multiple factors, including performance, fuel efficiency, maintenance costs, environmental impact, and cost. Diesel trucks are more potent, fuel-efficient, and durable but require more maintenance and are generally more expensive to purchase and repair. Gas trucks are more affordable, easier to maintain, and more environmentally friendly but have lower performance and shorter lifespans. Consider your specific needs, budget, and environmental concerns to make the right decision.
