GMC Terrain
Data verified by Nick Marchenko, PhD
Maintaining the right oil and coolant levels in your GMC Terrain is crucial for optimal engine performance. The 2010–2023 GMC Terrain offers a variety of engine options, including the 2.4L I-4 (LAF and LEA), 3.0L V-6 (LF1 and LFW), 3.6L V-6 (LFX), 1.6L I-4 diesel (LH7), and 2.0L turbocharged I-4 (LTG), as well as the 1.5L I-4 (LYX). Depending on the engine, oil capacities range from 4.2 to 6 quarts, with recommended viscosities primarily at 5W-30 or 0W-20. Additionally, coolant capacities vary, with most engines requiring between 7 and 10.8 quarts of coolant.
Regular oil changes are essential to ensure the longevity of your GMC Terrain's engine. For the petrol engines, using the correct oil viscosity and capacity is vital to prevent engine wear and maintain performance. Be sure to check your specific engine's requirements, as they differ across the model years and engine types.

Oil viscosity depends on the engine: LAF, LEA, LF1, LFW, LFX, LH7, LTG 2.0 L Turbo: 5W-30; LYX, LYX: 0W-20. Check your owner's manual for the correct spec for your specific engine.
What is the coolant capacity of the GMC Terrain?
The coolant capacity for the GMC Terrain varies by engine: LAF: 8.2 qt; LEA: 8.2 qt; LF1: 10.8 qt; LFW: 10.8 qt; LFX: 10.8 qt; LH7: 7.9 qt; LTG 2.0 L Turbo: 8.2 qt; LYX: 7.0 qt; LYX: 7.0 qt. Use the coolant specification listed in the owner's manual for your engine variant.
What type of oil does the GMC Terrain use?
The GMC Terrain primarily uses 5W-30 and 0W-20 motor oil, depending on the engine type. For example, the 2.4L I-4 engines use 5W-30, while the 1.5L I-4 engine uses 0W-20.
How many quarts of oil does the GMC Terrain take?
The oil capacity for the GMC Terrain varies by engine. The 2.4L I-4 engines require 5 quarts, while the 3.0L V-6 and 3.6L V-6 engines require 6 quarts. The 1.5L I-4 engine has a capacity of 4.2 or 5.3 quarts, depending on the specific variant.
How often should I change oil in a GMC Terrain?
Oil change intervals for the GMC Terrain typically range from 5,000 to 7,500 miles, depending on driving conditions and oil type used. It's advisable to consult the owner's manual for specific recommendations based on your engine.
What is the coolant capacity of the GMC Terrain?
The coolant capacity for the GMC Terrain varies by engine. Most petrol engines require between 8.2 and 10.8 quarts of coolant, while the 1.6L I-4 diesel engine requires 7.9 quarts.
Does the GMC Terrain need synthetic oil?
While synthetic oil is not mandatory for the GMC Terrain, it is recommended for better engine protection and performance. Using synthetic oil can extend oil change intervals and improve engine efficiency.
What happens if I use the wrong oil viscosity in my GMC Terrain?
Using the wrong oil viscosity can lead to inadequate lubrication, resulting in increased engine wear and potential damage. It's essential to use the recommended viscosity for your specific engine type.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks engine operating conditions to determine when an oil change is necessary. It takes into account factors like engine temperature, driving habits, and mileage to provide an accurate oil change interval.
Can I mix synthetic and conventional oil?
While it is technically possible to mix synthetic and conventional oils, it is not recommended. Mixing can reduce the effectiveness of the oil and may lead to engine issues.
How do I know if my GMC Terrain has an oil leak?
Signs of an oil leak in your GMC Terrain may include oil spots on the ground where you park, a burning oil smell, or a drop in oil levels without an apparent cause. Regularly checking the oil level can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by several factors, including worn piston rings, valve seals, or gaskets. It may also result from using the wrong oil viscosity or poor engine maintenance.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is cold, or after it has been turned off for a few minutes. This allows the oil to settle in the oil pan, providing a more accurate reading.
What is the difference between an oil change and a flush?
An oil change involves draining old oil and replacing it with new oil, while an oil flush is a process that cleans the engine's internal components by circulating a cleaning solution. Flushing is generally not necessary unless there are specific issues.
