2021 GMC Sierra 1500 Oil Type and Capacities

Chevrolet recommends that for all oil changes in the 2021 GMC Sierra 1500, ACDelco full synthetic motor oil is used.

I have done the work for you and found genuine oil and filter products on Amazon to make it that much easier for you.

The 2021 GMC Sierra 1500 requires 6.0 q of 5W-30 for the 2.7 L & 4.3 L engine and 7.0/8.0 q of 0W-20 for the 3.0 L Diesel/5.3 L and 6.2 L engines. See the chart below for links to products.

Engine	Oil Type	Capacity	Oil Filter
2.7 L Turbo	5W-30	5.7 L (6.0 qt)	ACDelco – PF66
3.0 L Duramax	0W-20	6.6 L (7.0 qt)	ACDelco – PF66
4.3 L V6	5W-30	5.7 L (6.0 q)	ACDelco – PF63

6.2 L V8	0W-20	7.6 L (8.0 q)	ACDelco – PF63

For the engines that use 5W-30, during extreme temperatures and operating under -20F, 0W-30 oil can be used in its place. It is important that no additives are put into the engine oil.
