Diesel vs. Gas Trucks: Pros and Cons

While there are pros and cons for diesel vs. gas trucks, the following are the main reasons why you might find each type of truck to be suited for your Spokane Valley lifestyle.

Reasons to Choose a Diesel Truck:

  • Torque & Towing – Diesel trucks often generate considerably more torque than gas-powered trucks. Therefore, they can often tow heavier loads, which makes them well-respected as work trucks and transport vehicles.
  • Fuel Economy – For a number of reasons, diesel engines tend to be more efficient than gas engines. Even though diesel fuel can sometimes be more expensive, many drivers prefer diesel because it reduces the number of stops they’ll need to make.
  • Longevity – Anecdotal and scientific evidence suggests that diesel engines can last much longer partly because they employ a simpler construction and stronger engine blocks. A well-maintained diesel engine can keep you going for more than 500,000 miles.

Reasons to Choose a Gas Truck:

  • Acceleration & Horsepower – Gas-powered trucks are generally better at getting up to speed and passing other cars in the Coeur d'Alene, ID traffic.
  • More Fueling Stations – Not every gas station offers diesel fuel, so it could be difficult to find the right fuel in the area.
  • Lower Maintenance Costs – Since diesel engines do not have spark plugs and generally have a simpler design, they can be cheaper to maintain. In fact, since diesel engines employ heavy-duty and sometimes hard-to-find parts, service and repair visits can be more expensive.

Technical Comparison: Gas & Diesel Engines

The diesel vs. gas truck pros and cons are strikingly different because of their engines. Here are more details:

  • Both gas and diesel engines are internal combustion engines, which means that fuel is turned into energy inside the engine. The opposite would be an external combustion engine, where heat is produced in one location and routed to the engine elsewhere.
  • Gas trucks tend to compress air and fuel at a ratio of roughly 10:1 while diesel trucks compress their own air/fuel mixture at a rate between 15:1 and 25:1. Since the result is a much hotter cylinder, diesel fuel is self-igniting and often does not require a spark plug.
  • The efficiency of any engine is determined in part by the relative difference between its maximum hot and cold temperatures. Higher compression ratios allow for a smaller minimum-maximum temperature difference, which accounts, in part, for the diesel engine’s higher MPG specs.
