GMC Acadia
Data verified by Nick Marchenko, PhD
Maintaining the engine oil in your GMC Acadia is crucial for optimal performance and longevity. Depending on the engine option, which includes a variety of petrol engines from 2007 to 2022, the oil capacity can range from 5 qt to 6.3 qt. For example, the LCV (2.5L I-4) engine requires 5 qt of 0W-20 oil for models from 2019 to 2021, while the LGX (3.6L V-6) engine has a capacity of 6 qt and uses 5W-30 oil for models from 2018 to 2022. Additionally, the coolant capacity varies, with some engines needing as much as 13.6 qt of coolant.
Regular oil changes are essential to keep your Acadia running smoothly. The specific viscosity and capacity requirements differ across the multiple engine options, including the LLT and LY7 V-6 engines, which have varying capacities and performance specifications. Always refer to your owner’s manual for the correct oil type and change intervals to ensure your vehicle remains in top condition.

What type of oil does the GMC Acadia use?
The GMC Acadia uses different types of oil depending on the engine. The LCV (2.5L I-4) engine uses 0W-20 oil, while the LGX and LLT (3.6L V-6) engines typically require 5W-30 oil. Always refer to your owner's manual for the specific requirements for your engine.
How many quarts of oil does the GMC Acadia take?
The oil capacity for the GMC Acadia varies by engine. For instance, the LCV (2.5L I-4) engine takes 5 qt, while the LGX (3.6L V-6) engines generally require 6 qt. The LLT engine has capacities ranging from 5.5 qt to 6.3 qt depending on the model year.
How often should I change oil in a GMC Acadia?
It's generally recommended to change the oil in your GMC Acadia every 5,000 to 7,500 miles, depending on driving conditions and oil type. If you use synthetic oil, you may extend the interval, but always consult your owner's manual for specific guidelines.
What is the coolant capacity of the GMC Acadia?
The coolant capacity for the GMC Acadia varies by engine. For example, the LCV (2.5L I-4) engine has a coolant capacity of 11.3 qt, while the LGX (3.6L V-6) engines can require between 12 qt and 13.6 qt depending on the model year.
Does the GMC Acadia need synthetic oil?
While the GMC Acadia can run on conventional oil, using synthetic oil is recommended for better performance and protection, especially in extreme temperatures. Synthetic oil can also extend the time between oil changes.
What happens if I use the wrong oil viscosity in my GMC Acadia?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's important to use the specified viscosity, such as 0W-20 or 5W-30, as recommended for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks the condition of your engine oil and alerts you when it's time for an oil change. It considers factors like engine temperature, driving habits, and mileage to provide a more accurate recommendation than a standard mileage interval.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oils, it's not recommended as it can reduce the effectiveness of the synthetic oil. If you switch to synthetic, it's best to do a complete oil change.
How do I know if my GMC Acadia has an oil leak?
Signs of an oil leak include oil spots or puddles under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regularly checking your oil level can help you identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn engine components, such as piston rings or valve seals, which allow oil to enter the combustion chamber. It can also be due to 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 warm but not hot. This allows the oil to circulate and gives a more accurate reading on the dipstick. Make sure to wait a few minutes after turning off the engine before checking.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush is a process that cleans the engine's oil passages and removes sludge buildup. Flushing is typically not necessary for regular maintenance.
