The 2021 Chevrolet Silverado 1500 is one of the most versatile light-duty pickup trucks in its class, offering four gas engines and one turbo-diesel engine. Although you can expect class-leading performance across the board, there are some differences between each of these engines to note. That’s why John Megel Chevrolet has put together the following comparison to help you decide which is right for you! Compare the new Silverado 1500 gas vs. diesel engines below to learn more about their individual specs, mpg ratings, and towing capacities. 

Silverado 1500 Gas vs. Diesel: Engine Options 

If you’re shopping for a regular, tried-and-true gas-powered engine, the Chevy Silverado 1500 offers the following engine choices:

  • 383 lb-ft of torque 
  • 8-speed automatic transmission (10-speed for the LT Trail Boss and High Country 4×4)

Duramax® 3.0L I6 Turbo-Diesel

  • 460 lb-ft of torque 
  • Auto-stop/start technology 
  • Available for the LT, RST, LTZ, and High Country configurations 

Silverado 1500 Gas Mileage 

One of the many benefits of diesel engines is increased fuel economy. As a light-duty pickup truck, the Silverado 1500 already achieves impressive mpg ratings due to its build. When you couple that with diesel technology, you can cruise right past Gainesville gas stations with a need for fewer fill-ups. Compare mpg ratings below: 

  • 6.2L EcoTec3 V8 w/ Dynamic Fuel Management™: TBD 
  • 5.3L EcoTec3 V8 w/ Dynamic Fuel Managment™: 16 mpg/21 mpg highway (LT Trail Boss; 4WD) 
  • 4.3L EcoTec3 V6 w/ Active Fuel Managment™: 16 mpg city/21 mpg highway (WT; 2WD)
  • 2.7L Turbo w/ Active Fuel Managment™: 20 mpg city/23 mpg highway (LT; 2WD) 
  • Duramax® 3.0L I6 Turbo-Diesel: 23 mpg city/33 mpg highway (with 2WD) 

Silverado 1500 Gas vs. Diesel: Towing Capacities 

The Silverado 1500’s highest towing capacity is achieved by its 6.2L EcoTec3 V8 engine. This engine, paired with the Double Cab/Standard Bed RST 4×4 configuration, the Max Trailering Package, and 20-inch wheels, can tow up to 13,300 pounds. The Duramax® Turbo-Diesel engine can tow up to 9,500 pounds when paired with the Double Cab/Standard Bed/2WD or Crew Cab/Short Bed/2WD configurations. No matter which engine you choose, the Silverado 1500 makes towing a breeze!
