The 2014 GMC Terrain with a 2.4 L engine typically requires about 4.8 quarts of oil for a full change with the filter, or roughly 4.5 quarts if you don’t replace the filter. Use Dexos1 Gen 2 5W-30 oil and verify the level with the dipstick after adding.
Overview of the engine and oil capacity
The 2014 Terrain uses a 2.4-liter inline-four Ecotec engine shared with several GM models. Understanding the oil capacity helps ensure proper lubrication, optimal engine performance, and accurate oil-level checks after servicing.
Official oil capacity and specifications
Below are the commonly cited capacities for the 2.4 L Ecotec engine used in the Terrain. These figures assume a standard oil change with the filter replaced. If the filter is not replaced, the capacity is slightly lower.
- 4.8 quarts (with oil filter) – typical capacity for a complete oil change.
- 4.5 quarts (without oil filter) – approximate capacity if the filter is not changed.
In practice, plan for about 5 quarts to accommodate minor variations, ensure the filter is filled, and top off as needed after checking the dipstick.
Oil type and maintenance tips
Use Dexos1 Gen 2 5W-30 engine oil (synthetic or synthetic-blend) as recommended by GM for this engine. Always follow the maintenance schedule in the owner’s manual and adjust intervals based on driving conditions and climate.
Summary
For a 2014 GMC Terrain with the 2.4 L engine, plan on about 4.8 quarts for a full oil change with a new filter (4.5 quarts if the filter isn’t replaced). Use Dexos1 Gen 2 5W-30 and confirm the final level with the dipstick after filling.
