The 2014 GMC Terrain’s oil capacity depends on the engine installed. The 2.4-liter four-cylinder engine requires about 5 quarts of oil with a filter, while the 3.6-liter V6 requires about 6 quarts with a filter. Always verify against the owner’s manual and use a Dexos-approved oil and a new filter during any oil change.
Engine options and oil capacity
The Terrain was offered with two gasoline engines in 2014. The following figures reflect typical oil capacities for a standard oil change.
- 2.4L I4 — Approximately 5 quarts (about 4.7 liters) of engine oil with filter.
- 3.6L V6 — Approximately 6 quarts (about 5.7 liters) of engine oil with filter.
Note: Capacities refer to the oil change fill with a new filter. Exact amounts can vary slightly by production batch or market.
Oil type and service recommendations
Use a Dexos-approved engine oil with the viscosity suited to your climate and the manual’s guidance. In many 2014 Terrain models, the common recommendations are:
- Viscosity: 5W-30 is typical; some climates or engine versions may specify 0W-20 or 5W-20.
- Specification: Dexos1 Gen 2 (and Dexos2 where applicable) as required by GM for gasoline engines.
- Oil filter: Use a quality filter that meets OEM specifications.
After adding oil, run the engine and recheck the level with the dipstick to ensure accuracy.
Bottom-line tips for servicing
Choose the right oil capacity based on your engine, verify the recommended viscosity in the owner’s manual, and ensure you use a Dexos-approved oil and a compatible filter. If in doubt, consult a GM dealer or qualified mechanic.
Summary: The 2014 GMC Terrain requires about 5 quarts of oil with a filter for the 2.4L engine and about 6 quarts with a filter for the 3.6L engine. Use Dexos-approved 5W-30 (or the spec listed in your manual) and replace the oil filter with every change.
