Oil capacity by engine

EngineOil Type (viscosity)Capacity w/ FilterCapacity w/o FilterNotes
1.5L — SLT, 1.5L Eng VIN V, 4WD, 1.5L Eng,4WDAPI - SAE 0W-205.30 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended.
1.5L — SLT, 1.5L Eng VIN V, FWD, 1.5L Eng,FWDAPI - SAE 0W-204.20 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended.
2.0L — SLT, 2.0L Eng VIN X, 4WD, 2.0L Eng,4WDAPI - SAE 5W-306.00 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended. If in an area of extreme cold, where the temperature falls below -20Deg.F (-29Deg.C), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.
2.0L — SLT, 2.0L Eng VIN X, FWD, 2.0L Eng,FWDAPI - SAE 5W-305.00 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended. If in an area of extreme cold, where the temperature falls below -20Deg.F (-29Deg.C), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.
Denali, 4WD — 2.0L Eng,4WDAPI - SAE 5W-306.00 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended. If in an area of extreme cold, where the temperature falls below -20Deg.F (-29Deg.C), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.

ACDelco dexos1 Synthetic Blend is recommended. If in an area of extreme cold, where the temperature falls below -20Deg.F (-29Deg.C), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.
SL — 1.5L Eng,FWDAPI - SAE 0W-204.20 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended.
SLE, 4WD — 1.5L Eng,4WDAPI - SAE 0W-205.30 QTS.—Use only engine oil licensed to the dexos1 specification, or equivalent, of the proper SAE viscosity grade. ACDelco dexos1 Synthetic Blend is recommended.

Frequently asked questions

What type of oil does a 2020 GMC Terrain take?

It depends on the engine: 1.5L uses 0W-20; 1.5L uses 0W-20; 2.0L uses 5W-30; 2.0L uses 5W-30; Denali, 4WD uses 5W-30; Denali, FWD uses 5W-30; SL uses 0W-20; SLE, 4WD uses 0W-20; SLE, FWD uses 0W-20.

What is the oil capacity of a 2020 GMC Terrain?

Oil capacity depends on the engine: 1.5L holds 5.3 quarts with filter; 1.5L holds 4.2 quarts with filter; 2.0L holds 6.0 quarts with filter; 2.0L holds 5.0 quarts with filter; Denali, 4WD holds 6.0 quarts with filter; Denali, FWD holds 5.0 quarts with filter; SL holds 4.2 quarts with filter; SLE, 4WD holds 5.3 quarts with filter; SLE, FWD holds 4.2 quarts with filter.

How often should I change the oil in my 2020 GMC Terrain?

Most 2020 GMC Terrain owners follow a 5,000–7,500 mile interval with conventional oil, or up to 10,000 miles with full synthetic. Always check the oil life monitor if equipped, and consult your owner's manual — GMC recommends intervals based on driving conditions, not just mileage.

Can I use synthetic oil in my 2020 GMC Terrain?

Yes. 0W-20 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 2020 GMC Terrain. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
