The oil you should use in a 2010 GMC Terrain is Dexos1-certified 5W-30 motor oil (synthetic or synthetic-blend). The 2.4-liter four-cylinder engine typically uses about 5 quarts, while the 3.0-liter V6 uses about 6 quarts per change.
In 2010, the Terrain was offered with two engines. This article explains the official oil specification, expected capacities, and practical maintenance tips to keep the SUV running smoothly.
Engine options and oil requirements
The two engines share the same general oil grade requirement, but the fill amount varies by displacement. The recommended oil is Dexos1-certified 5W-30 for both the 2.4L I4 and the 3.0L V6, and both can use synthetic or synthetic-blend formulations.
Why Dexos1 5W-30?
Dexos1 is GM’s approved oil specification designed to meet modern engine tolerances and warranty requirements. Using a Dexos1-certified 5W-30 helps ensure proper lubrication, performance, and protection across driving conditions for the 2010 Terrain’s engines.
The following summarizes the specific oil grade and how much oil each engine typically holds.
- Dexos1-certified 5W-30 motor oil (synthetic or synthetic-blend) is recommended for both engines in the 2010 Terrain.
In short, use the recommended 5W-30 Dexos1, and pair it with a compatible oil filter. Always verify the fill level with the dipstick after changing the oil.
Oil capacity by engine
Oil capacity depends on which engine your Terrain has. The figures below are typical for a standard oil change with a new filter.
- 2.4L I4: approximately 5 quarts (about 4.8–5.0 qt) of oil with filter.
- 3.0L V6: approximately 6 quarts (about 5.5–6.0 qt) of oil with filter.
After refilling, recheck the level to ensure it sits within the optimum range on the dipstick before closing the hood.
Maintenance tips and intervals
Oil-change intervals depend on oil type and how you drive. General guidelines are:
- Conventional oil: roughly every 3,000–5,000 miles.
- Synthetic-blend oil: roughly every 5,000–7,500 miles.
- Full synthetic oil: roughly every 7,500–10,000 miles.
Always refer to the owner’s manual for the exact interval and any GM service bulletins. Use a high-quality filter (typically OEM/ACDelco) and keep service records for warranty considerations.
Summary
For a 2010 GMC Terrain, the recommended oil is Dexos1-certified 5W-30 (synthetic or synthetic-blend). The 2.4L engine uses about 5 quarts, and the 3.0L V6 uses about 6 quarts per change. Follow the vehicle’s maintenance schedule and use an OEM-recommended oil filter to maintain engine performance and protection.
