Data verified by Nick Marchenko, PhD
Maintaining your 2008–2022 Buick Enclave is crucial for optimal performance and longevity. This vehicle offers six engine options, including the LFY and LLT 3.6L V6 petrol engines. Depending on the model year, the oil capacity varies; for example, the LFY engine from 2018 requires 6 quarts of 5W-30 oil, while the LLT engine from 2008 has a capacity of 5.5 quarts. Additionally, coolant capacities range from 11.4 to 17.6 quarts, depending on the specific engine variant.
Regular oil changes are essential to keep your Buick Enclave running smoothly. For the LFY engine, the recommended oil change interval is typically every 7,500 miles, while the LLT engine may require more frequent changes. Always refer to your owner's manual for the specific requirements of your engine to ensure you are using the correct oil viscosity and maintaining the proper coolant levels.

Buick Enclave – Frequently Asked Questions
How many quarts of oil does the Buick Enclave take?
The Buick Enclave oil capacity varies by engine: LFY: 6.0 qt; LFY: 6.0 qt; LLT: 5.5 qt; LLT: 5.5 qt; LLT: 6.0 qt; LLT: 11.4 qt. Always confirm the exact capacity for your specific engine before an oil change.
What type of oil does the Buick Enclave use?
The Buick Enclave uses 5W-30 engine oil across all its engine variants. Full synthetic oil meeting API/ILSAC specifications is strongly recommended for optimal engine protection and performance.
What is the coolant capacity of the Buick Enclave?
The coolant capacity for the Buick Enclave varies by engine: LFY: 15.3 qt; LFY: 17.6 qt; LLT: 11.4 qt; LLT: 12.3 qt; LLT: 11.9 qt; LLT: 11.4 qt. Use the coolant specification listed in the owner's manual for your engine variant.
What type of oil does the Buick Enclave use?
The Buick Enclave typically uses 5W-30 viscosity engine oil. This is recommended for all engine options across the production years.
How many quarts of oil does the Buick Enclave take?
The oil capacity varies by engine. The LFY engine from 2018 takes 6 quarts, while the LLT engine from 2008 takes 5.5 quarts.
How often should I change oil in a Buick Enclave?
For the LFY engine, oil changes are generally recommended every 7,500 miles. The LLT engine may require more frequent changes, so always check your owner's manual.
What is the coolant capacity of the Buick Enclave?
Coolant capacity varies by engine. The LFY engine from 2022 has a coolant capacity of 17.6 quarts, while the LLT engine from 2008 has a capacity of 12.3 quarts.
Does the Buick Enclave need synthetic oil?
While synthetic oil is not mandatory, it is highly recommended for better performance and protection, especially in extreme temperatures.
What happens if I use the wrong oil viscosity in my Buick Enclave?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. Always use the recommended 5W-30 viscosity.
What is an oil life monitor and how does it work?
An oil life monitor tracks engine operating conditions and calculates when an oil change is needed. It considers factors like driving habits and engine temperature.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oils, it is not recommended as it can reduce the effectiveness of the oil's performance.
How do I know if my Buick Enclave has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a burning oil smell, or a drop in oil levels. Regularly checking your oil level can help detect leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets. It's important to diagnose the issue to prevent engine damage.
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 provides 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 cleans the engine internals to remove sludge and deposits before a new oil change.
