Most 2014 Terrain models use either about 4.5 quarts (for the 2.4-liter four-cylinder) or about 6 quarts (for the 3.6-liter V6). Always verify with your owner’s manual or under-hood specifications to avoid under- or over-filling.
Engine options for the 2014 Terrain
The Terrain was offered with two gasoline engines in 2014: a 2.4L inline-4 and a 3.6L V6. The 2.4L is paired with a 6-speed automatic transmission and is commonly found in front- or all-wheel-drive configurations. The 3.6L V6 was available in higher trims and AWD, delivering more horsepower at the cost of higher fuel use.
2.4-liter inline-4 (I4)
Oil capacity for the 2.4L engine is typically 4.5 quarts with a new filter. Ensure you fill to the correct level on the dipstick after changing the filter and oil, and use the viscosity recommended by GM (commonly 5W-30 in most climates).
3.6-liter V6
Oil capacity for the 3.6L V6 is about 6 quarts with a new filter. Use the manufacturer's recommended oil type and viscosity, and recheck level after filling.
How to confirm your exact engine and oil capacity
Because the Terrain could be equipped with either engine depending on trim and market, verify your specific engine to confirm the precise oil capacity. Use these steps:
- Check the VIN plate on the driver’s door jamb for an engine code, or look up your VIN online or via GM’s service tools.
- Inspect the engine: the 2.4L is a four-cylinder; the 3.6L is a larger V6 with a distinct intake and exhaust layout.
- Consult the owner’s manual or Service Information for the vehicle's exact specification.
- Ask a GM dealer or service shop with your VIN to confirm the correct capacity.
Knowing the exact engine is essential for a correct fill, since overfilling or underfilling can affect engine lubrication and performance.
Summary
For the 2014 GMC Terrain, plan for about 4.5 quarts of oil if you have the 2.4L inline-4, or about 6 quarts if you have the 3.6L V6. Always verify with your owner’s manual or dealer using your VIN to ensure you use the exact capacity and the correct oil specification for your vehicle.
