While car maintenance might feel like a pain in the neck (and wallet), keeping up with it is the best way to curtail any serious (and expensive!) repairs down the line and keep your vehicle in tip-top shape. Changing the engine oil in your 2007 GMC Duramax is not only easy but it’s affordable, too!
2007 GMC Duramax engine oil capacity
The 2007 GMC Duramax has an engine oil capacity of 10 quarts or 9.5 liters. If you are checking your owner’s manual to find this information, don’t get engine oil capacity mixed up with your engine’s displacement, which is the volume of the cylinders. This is not the amount of engine oil your GMC needs.
What kind of oil does a 2007 GMC Duramax need?
Your GMC Duramax won’t take just any oil—it needs 15W-40 synthetic oil. If you’re not sure what those letters and numbers mean, we’ll break it down for you.
The 15W-40 synthetic oil reduces wear on heavy-duty engines and performs well in cold weather conditions. The letter “W” refers to winter, and the two numbers indicate the oil’s viscosity (or thickness) at different temperatures.
The first number is the oil’s viscosity when it is cold. The second is the oil’s viscosity when the engine reaches full operating temperature.
How often to change oil on a 2007 GMC Duramax
GMC recommends you change your engine oil every 10,000 miles or annually—whichever comes first. If you drive more than the average person, you may be better off changing your oil every six months. However, checking your oil once a month will guarantee you know exactly when your oil needs to be changed and prevent any serious issues.

How to change your oil and oil filter
It’s almost time to start changing the oil in your 2007 GMC Duramax! All that’s left to do is gather your tools and materials. Grab a socket and filter wrench, a drain pan, a replacement filter, and 10 quarts of 15W-40 motor oil.
Now that you’ve got everything you need, let’s get started. Run your engine until it reaches normal operating temperature. This usually only takes five minutes. Then, you can change your oil like a pro by following these steps:
Before you pat yourself on the back, use the dipstick to check your oil levels and make sure you’ve added enough oil to your engine.
After changing your oil, it’s a good idea to turn on your car and let your engine run for about 30 seconds before you check the oil level. This will give you a more accurate measurement, and you’ll be able to top it off if necessary.
If the oil pressure light is off, you successfully changed your GMC’s oil! Now you can finally clean up. Pour the old oil into a sealed container and bring it to the local recycling center to properly dispose of it.
