Diesel vs. Gas Trucks: Pros and Cons

If you’re deciding between diesel vs. gas trucks, pros and cons for both will help you make the right call. We suggest diesel if you need concentrated power for the toughest towing and hauling jobs, or commercial transport. On the other hand, the higher horsepower of gas engines is an advantage when you’re dealing with highway traffic. Compare diesel vs. gas trucks in detail, below:

Why Choose Diesel?

  • Torque and Towing: The most impressive towing specs come from diesel engines, which are able to generate more torque than gas engines. That matters—because the twisting force of torque is the key component of a vehicle’s towing and hauling capability.
  • Fuel Economy: Diesel fuel can be more expensive than traditional gasoline, but diesel engines balance it out by using that fuel far more efficiently. As a result, you’ll save on fuel if you’re on the road for long stretches between jobs in Mesa and Gilbert.
  • Longevity: Because they’re easier to maintain than gas-powered engines, diesel engines tend to require fewer repairs and last longer.

Why Choose Gas?

  • Acceleration and Horsepower: Diesel may take the prize for torque, but gas trucks have a horsepower advantage. On the road in Tempe, that means better acceleration and higher top speeds.
  • Easier Fueling: There’s one good reason that gas engines are so much more popular than diesel: gasoline is the easier fuel to find. If you’re often driving in unfamiliar areas, then a gasoline truck may be a more sensible choice.
  • Lower Service Costs: The simpler diesel engine design leads to fewer repairs, but those repairs cost a lot more when you do need them. Fixes for gasoline engines are more routine, and will likely cost less. All in all, while the cost of maintaining diesel vs. gas truck engines even out over time, a gas truck will cost you less in the short term.
