The 2013 GMC Terrain V6 requires about 6 quarts (5.7 liters) of engine oil with a filter, using Dexos1 5W-30 synthetic oil.
The Terrain line for 2013 offered a 3.0-liter V6 option alongside the 2.4-liter four-cylinder. For the V6 variant, oil capacity is 6 quarts (5.7 L) with the filter. Always verify the exact specification for your vehicle in the owner's manual or the door sticker, as production changes can affect capacity.
Oil capacity and specifications
Key specifications you should know at a glance:
- Oil capacity with filter: 6 quarts (5.7 liters).
- Recommended oil: Dexos1 Gen 2 5W-30 synthetic (for gasoline engines).
- Note: Use a quality synthetic to maximize protection and longevity, per GM guidelines.
These figures specifically apply to the 3.0L V6 option of the 2013 Terrain. If your vehicle has the 2.4L four-cylinder, capacity and oil specs differ; check the owner's manual for that engine.
Step-by-step oil change procedure
If you’re performing the oil change yourself, use the following steps as a guide. Ensure you have a suitable drain pan, the correct filter, and a new OEM drain plug gasket if required.
- Warm up the engine to operating temperature, then turn off and secure the vehicle.
- Raise the front of the vehicle and support securely with jack stands if you need to access the drain plug.
- Place a drain pan under the oil pan, remove the drain plug, and allow the oil to fully drain.
- Remove and replace the oil filter. Note the filter orientation and use a new gasket if applicable.
- Reinstall the drain plug and tighten to manufacturer specification. Start with adding about 5.5 quarts (roughly 5.2 liters) of oil, then check the level.
- Reinstall the oil filler cap, start the engine, and run for a minute to pressurize the system; turn off and wait a few minutes to let the oil settle.
- Check the dipstick and add oil as needed to bring the level to the full mark. Recheck for leaks; reset the oil-change indicator if equipped.
After completing the change, confirm the oil level is within the full range on the dipstick and inspect for leaks around the drain plug and filter. If unsure, have a professional perform the change.
Oil type and viscosity notes
GM generally recommends Dexos1 Gen 2 5W-30 synthetic for the 2013 Terrain V6. Always confirm the exact specification for your region and VIN from the owner's manual or a dealership, as regional requirements can vary.
Maintenance interval guidance
Under normal driving, synthetic oil often supports longer intervals (often around 7,500 miles), but severe driving conditions—such as frequent short trips, towing, extreme heat, or heavy loads—may require more frequent changes (3,000–5,000 miles). Follow the schedule in your manual and adjust based on usage and conditions.
Summary
The 2013 GMC Terrain V6 typically takes 6 quarts (5.7 liters) of Dexos1 5W-30 synthetic oil, with the filter. When changing the oil, start with about 5.5 quarts and top up to the full mark after verifying with the dipstick. Always use the oil specification recommended by GM for your VIN and consult the owner’s manual for precise guidance.
