Buffalo-area truck drivers want to know: What are the pros and cons of choosing a diesel vs. gas truck? The answer is simple. Check out the Joe Basil Chevrolet guide to the benefits offered by each so you can choose which is best for you and your daily drives.

Diesel vs. Gas Trucks Pros and Cons

Reasons to Choose a Diesel Truck

  • Torque and Towing – Diesel trucks like the 2020 Chevy Silverado often generate considerably more torque than their gas-powered counterparts. As a result, they can often tow heavier loads in comparison to gas-powered engines of similar sizes. This 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 to refuel when they’re traveling out past Lancaster.
  • Longevity – Anecdotal and scientific evidence suggests that diesel engines can last much, much longer than otherwise-comparable gas engines, partly because they employ a simpler construction and stronger engine blocks. A well-maintained diesel engine can power your travels for more than 500,000 miles.

Reasons to Choose a Gas Truck

  • Acceleration and Horsepower – True, diesel engines tend to offer more torque. However, for many daily drivers, it’s a vehicle’s horsepower and acceleration specs that really matter. Gas-powered trucks are generally better at getting up to speed and passing other cars.
  • More Fueling Stations – Not every gas station offers diesel fuel, so drivers who choose a gasoline-powered truck are going to spend less time worrying about where to find their next fill-up near Cheektowaga.
  • Lower Maintenance Costs – Since diesel engines do not have spark plugs, and generally employ a simpler design, many drivers expect them to be cheaper to maintain. In fact, since diesel engines employ heavy-duty and sometimes hard-to-find parts, service appointments and repairs can often be pricier than gas truck powertrain repairs.

Technical Comparison: Gas and Diesel Engines

You may be wondering why the differences between gas and diesel trucks are pronounced. When comparing your options, you may want to keep the following in mind:

  • Both gas and diesel engines are internal combustion engines, which simply means that fuel is turned into energy inside the engine itself. 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. 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 min-max temperature difference, which accounts, in part, for the diesel engine’s greater fuel economy.
