The Chevy Silverado offers extreme power in a full-size light-duty truck. But what’s the best Chevy Silverado engine choice for the way you work and drive in Lakeland: a 5.3L V8 gasoline engine or a 3.0L Duramax diesel engine? What’s the difference between these Chevy engines, besides whether they use diesel or gasoline? While the diesel engine requires less maintenance and offers better fuel efficiency, the gasoline engine is the class leader when it comes to towing, while offering better acceleration. Take a closer look at how the Chevy Duramax diesel engine vs. the Chevy 5.3L engine compare with Chevrolet Center Inc.

3L Duramax Diesel vs. 5.3L V8: Key Specs of the Chevy Engines

Whether you choose the diesel or gas engine option for your Chevy Silverado ultimately comes down to what you need to prioritize when you’re driving in Haines City. Need towing power and get-up-and-go? Or is efficiency what you need? Take a look at the specs between the Chevy Duramax diesel engine vs. the  Chevy 5.3L engine:

5.3L V8 Gasoline Engine

  • Output – 355 horsepower and 383 pound-feet of torque
  • Efficiency (RWD) – EPA-estimated 17/23 city/highway MPG
  • Efficiency (4WD) – EPA-estimated 16/22 city/highway MPG
  • Availability – All Silverado trims

3.0L 6-cylinder Turbodiesel

  • Output – 277 horsepower and 460 pound-feet of torque
  • Efficiency (FWD) – EPA-estimated 23/33 city/highway MPG
  • Efficiency (4WD) – EPA-estimated 22/26 city/highway MPG
  • Availability – LT, RST, LTZ, High Country trims

You’ll get the same 460 lb-ft of torque with both engines, but the diesel delivers it by 1,500 rpm vs. 4,100 rpm for the V8. As a result, the V8 needs to work harder than the diesel to get the same amount of power on the highway.

3L Duramax Diesel vs. 5.3L V8: Towing Capability

The biggest draw of the V8 for Davenport drivers is its superior towing capacity: a maximum 13,400 pounds, compared to 9,300 pounds for the diesel. While 9,300 pounds is more than adequate for plenty of Winter Haven towing jobs, some extra capacity may be necessary if you’re driving your Chevy Silverado in a commercial setting or towing a fifth-wheel trailer or large boat. And while the altitude in Winter Haven is low, if you happen to be towing into higher-altitude locations, a diesel engine with a turbocharger will be more consistent.
