If you are in the market for a dependable pickup in the Mesa area, it’s likely that you are comparing diesel vs. gas options. It’s no surprise that one of the most common questions we hear at Trucks Only is, “Should I get a diesel or gas truck?” There is not really a one-size-fits-all answer to this question. It truly comes down to your preferences, priorities, and driving needs. Explore the benefits of diesel trucks and gas trucks below to see which one is better suited to your needs in Mesa. 

Should I Get a Diesel or Gas Truck?

Benefits of Diesel Trucks 

  • Torque & Towing – In most cases, diesel trucks deliver a higher torque output than their gas-powered counterparts. Because of this, they are often able to tow more, too. If you do a lot of heavy towing at the job site, a diesel truck may be a better fit. 
  • Fuel Economy – Diesel engines tend to be more efficient than gas engines. If you prefer making fewer stops to refuel, we highly recommend considering a diesel truck. 
  • Longevity – Diesel engines have a simpler construction and stronger engine blocks. This is one of the many reasons why the longevity of diesel trucks is so impressive. Did you know that a diesel engine that has been properly maintained can last well over 500,000 miles?

Benefits of Gas Trucks 

  • Acceleration & Horsepower – If you do a lot of highway driving around Mesa, opting for a gas-powered pickup is likely your best bet. They are typically better at getting up to speed and passing other cars.
  • More Fueling Stations – You may not be able to find diesel fuel at every gas station you visit. 
  • Lower Maintenance Costs – Although diesel engines do not need spark plugs and have a less complex design, they could end up costing more to maintain than their gasoline-powered counterparts. This is because they contain heavy-duty and sometimes hard-to-find parts. This can lead to pricier service appointments

Diesel vs. Gas – Technical Specifications and More

  • Both gas and diesel engines are internal combustion engines. What does this mean? Put simply, fuel is turned into energy inside the engine itself. 
  • Gas trucks usually compress air and fuel at a ratio of approximately 10:1. Diesel trucks compress their own air/fuel mixture at a rate that ranges from 15:1 and 25:1. This is why most diesel trucks do not require spark plugs. The fuel is self-igniting due to the significantly higher heat. 
  • Why are diesel trucks generally more efficient? The relative difference between an engine’s maximum hot and cold temperatures certainly plays a role. Expect a smaller difference between the two with a higher compression ratio.
