You’ll find that diesel engines offer incredible power and efficiency during your Midlothian drives. Duramax is a line of diesel V8 engines you’ll find in Chevy and GMC vehicles. Find out who makes Duramax and what trucks use Duramax at Legacy Chevrolet of Waxahachie near Ennis. 

Who Makes Duramax?

The engine in a Duramax was built in Moraine, Ohio, at a manufacturing facility that makes around 200,000 Duramax engines a year. The company that makes Duramax engines is a partnership between General Motors and Isuzu, so they make proprietary diesel engines for GMC, Chevy, and Isuzu.

What Trucks Use the Duramax Engine?

Does the GMC or Chevy you drive around Corsicana have a Duramax engine? These are the current GMC and Chevy Duramax-equipped vehicles: 

6.6L Duramax Turbo-Diesel V8 

  • GMC Sierra Heavy Duty

3.0L Duramax Turbo-Diesel 

  • GMC Sierra 1500 (best-in-class highway fuel economy)
  • GMC Yukon

If you’re driving an older GMC or Chevrolet truck, you can look at your truck’s VIN to determine if it has a Duramax engine: 

  • LB7: Duramax engines first came out in 2001 with this VIN for Chevy Silverado HD and GMC Sierra HD trucks.
  • LLY: These VINs are 6.6L Duramax, turbocharged, 32-valve engines from 2004 and 2005.
  • LBZ: Duramax diesel engines that were made in 2006 and 2007.
  • LMM: Duramax diesel engines made from 2007 to 2011, coupled with Allison transmissions for the first time.
  • L5P: These Duramax diesel engines hit the production line in 2017.

What Oil Does a Duramax Engine Need?

General Motors recommends SAE 15W-40 engine oil for all Duramax diesel engines. For TX drivers who have to consider sub-zero temperatures at times, GM recommends 5W-40 motor oil. Other oil weights can congeal at low temperatures. Then it can stick to the engine’s pistons and cause significant damage. During summer months in Waxahachie, a fully synthetic 15W-40 motor oil is a good fit.
