Diesel vs. Gas Trucks

When comparing diesel vs. gas trucks, each offers advantages and limitations. When it comes to work trucks, there is no definitive answer to which is better. However, it is important to know the differences so you can consider which option will be best for your business. Below we have listed a few key points to consider:

Fuel Economy

According to the U.S. Department of Energy, diesel engines offer 30% to 35% greater fuel economy than gasoline engines. Diesels offer better fuel economy, though it may take around 150,000 miles before the fuel cost-benefit makes up for the initial price premium. A diesel truck makes sense if you plan to tow a lot or drive a lot of miles. It is worth noting that diesel fuel is more expensive than gasoline, but even with the increased cost of diesel, you can expect to pay less in fuel costs yearly compared to gas trucks.


Gasoline and Diesel trucks have different life expectancies. Diesel engines typically last longer because diesel is a light oil that lubricates the engine when burned. Additionally, the castings and cylinder walls are built thicker and the oiling system has a higher volume, so they can handle higher compression ratios than your average gas engine. A gasoline engine will turn twice as many revolutions per minute than a diesel truck, meaning the diesel truck wears at half the rate of the gas truck. Less stress on the engine will result in a longer life expectancy. 

Capability, Off-Roading, and Efficiency

When considering renting a diesel or gas truck for the daily grind at work, you should think about efficiency. Diesel engines deliver exceptional miles per gallon. As for capability, a diesel truck will generally work best for towing while gas trucks will work best for lighter-duty jobs. If your work takes you off-road, gas trucks are a better option since they rev faster and redline higher.


A diesel truck is a great option if towing capacity is critical to your business needs. A diesel trucker offers more torque that is better suited for pulling heavy loads up steep grades.

A diesel engine is a more practical choice if towing capacity is critical to your business needs. A diesel truck has a torque advantage that is better suited for pulling heavy loads up steep grades. Diesel trucks also have a larger towing capacity. For example, the 2020 RAM 1500 Laramie has a towing capacity of 11,610 lbs, and the 2020 RAM 2500 Laramie has a towing capacity of 19,680 lbs.

Should I rent a Diesel or Gas Truck?

If heavy-duty towing and driving long distances are something your business does on a regular basis than a diesel pickup truck rental is the choice for you.

If you need something that will take you off road and your business hauls lighter items that gas trucks are the best option for your business. Gas trucks offer a wider range of makes and models, which highlights the diesel’s role as a specialty truck.

Lastly, consider your towing requirements when choosing a diesel vs. a gas truck. Does your work necessitate a diesel engine or will a gas engine suffice?
