Why Engine Oil Capacity Matters
Engine oil plays a vital role in the overall health and performance of your Duramax engine. It lubricates moving parts, prevents corrosion, and helps to regulate engine temperature.

Checking Engine Oil Level
To ensure your Duramax engine is running with the correct oil level, it’s essential to check it regularly. Here’s a step-by-step guide:
- Make sure your engine is at the recommended operating temperature.
- Locate the oil dipstick under the hood, near the front of the engine.
- Pull out the dipstick and wipe it clean with a lint-free cloth or paper towel.
