Medium Commercial Trucks: Diesel vs. Gas

By June 30, 2022Truck Blog

When looking for new or used delivery vans and other types of vehicle, there are many factors to consider, but many drivers begin by deciding on engine types. 

Is diesel superior to gasoline? 

While diesel vehicles have greater torque, pulling power, better gas efficiency, and last longer, gas trucks are often lighter, quicker, and better at handling big weights. 

You may also compare diesel vs. gas trucks in more depth below and determine which is best for your company.

When is it better to choose a diesel truck?

Output Torque

Diesel trucks are known for their extremely high torque outputs, making them ideal for drivers that want heavy-duty capabilities. When comparing towing capabilities between diesel and gas vehicles, the benefit of increased torque is especially obvious, since diesel trucks can often draw considerably bigger loads.

Fuel Efficiency

Diesel engines are more costly than gasoline engines, but they provide better gas mileage. This means you can drive throughout Milwaukee without needing to stay near a gas station. 


Diesel engines have a simpler design than gasoline ones. Because they are heavier and have fewer moving components, you are more likely to encounter fewer issues during the engine’s lifetime. When all is said and done, diesel engines may live far longer than gas engines.

When is it better to choose a gas truck?

Acceleration & Horsepower

Gas engines have the advantage in terms of horsepower and acceleration. When hauling a large load, a diesel engine with lots of power can assist you get up to speed, but gas trucks are a little better at passing other cars on the highway.

Payload Capacity

When all other factors are equal, a lighter truck may carry a greater payload than a heavier vehicle. After all, the axles and tires of your car can only take so much weight. Due to the fact that diesel engines are heavier than gas engines, a truck with a gas engine can often carry greater weight in its cargo bed.

Fuel Fill-Ups Made Simple

No matter where you travel, you can easily locate a gas station. Finding a gas station that also offers diesel fuel might be more difficult.

Maintenance is easier

Service professionals are more experienced with gas engines than diesel engines. This means less money spent on engine repairs, components, and tune-ups. An older gas engine, on the other hand, might develop more issues than its heavier diesel equivalent.

Additional Considerations

We’ve already covered some of the fundamentals, but what about the finer points like combustion, compression, and temperature?

  • Is diesel superior to gas in terms of combustion? Both gas and diesel engines use combustion technology, thus this isn’t the case;
  • Diesel engines typically have a compression ratio of 15:1 to 25:1 on average. This ratio is greater than the 10:1 norm for gasoline engines. Without the need of spark plugs, diesel engines may self-ignite.
  • The maximum cold and hot temperatures in the gas and diesel engines’ cycles varies slightly. A diesel engine’s fuel efficiency benefits from this little differential.

Many of the same considerations apply whether you’re evaluating gas vs. diesel for the RAM 2500, Ford F-250, or Silverado HD. However, you’re surely aware that the gas and diesel engines supplied by each range might differ significantly. Diesel engine comparisons are equally as significant as diesel vs. gas engine comparisons.
