Max. Fuel Economy
Are you considering a new Chevrolet Silverado? If so, you’ll have a few engines available to you — two of which are the 3.0L Duramax diesel engine and the 5.3L EcoTec3 gas-powered V8 engine. Which engine is the better choice for your commutes around Tallahassee? To better illustrate their differences, we’ve compared the same model — the 2021 Chevy Silverado 1500 RST — and its figures when equipped with either engine. Compare these two powerful GM engines, so you can make an informed decision when you spring for a new truck!
When you compare the Duramax I6 and EcoTec3 V8 engines, you’ll notice some differences in horsepower, torque, and towing figures, as well as different transmissions. Below, we’ve compared the specs for the EcoTec3 and Duramax engines, as well as the towing abilities of the Silverado 1500 RST with either of these machines:
With 4WD, a 3.23 gear ratio, and the 3.0L Duramax engine, the Chevy Silverado 1500 RST Crew Cab/Short Bed configuration has a maximum towing capacity from the ball of 9,000 pounds. The 3.0L Duramax engine more than pulls its weight. In fact, the RST with the 5.3L EcoTec3 V8 only tows about 400 more pounds than the RST with the Duramax (from the ball). For a smaller engine, the Duramax certainly packs a big punch!
When compared to the 3.0L Duramax I6, the 5.3L EcoTec3 V8 is more powerful if we’re going by horsepower alone. However, when you compare the fuel economy specs of both engines, you’ll notice that the Duramax diesel is more fuel efficient:

If you’re shopping for an engine that’s capable in its own right and offers impressive mpg ratings, the Duramax diesel is definitely in a category by itself.
