Who Makes Duramax?

The engine in a GMC 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 GMC Vehicles Use Duramax?

Does the GMC you drive in Columbus have a Duramax engine? These are the current GMC 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 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 Duramax Engines Need?

General Motors recommends SAE 15W-40 engine oil for all Duramax diesel engines. For NE drivers who have to consider sub-zero temperatures at times, GM recommended 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 Fremont a fully-synthetic 15W-40 motor oil is a good fit.
