GMC Yukon XL
Data verified by Nick Marchenko, PhD
The 2016–2022 GMC Yukon XL is a robust SUV that offers a range of powerful engine options, including the L83 (5.3L V-8), L86 (6.2L V-8), L87 (6.2L V-8), and the LM2 (3.0L I-6) diesel engine. Proper oil maintenance is crucial for ensuring optimal performance and longevity of your vehicle. For the L83 engines, the oil capacity is 8 quarts with a viscosity of 0W-20, while the LM2 diesel engine requires 7 quarts of the same viscosity. Additionally, the coolant capacities vary, with the L83 needing 15.6 to 17.9 quarts depending on the model year, and the LM2 requiring 21.9 quarts.
Regular oil changes are essential, particularly for the L86 and L87 engines, which also utilize 8 quarts of 0W-20 oil. Keeping an eye on your oil levels and ensuring you use the correct viscosity will help maintain the impressive horsepower and torque ratings, such as the 420 hp and 460 lb-ft in the L86 and L87 engines. Always refer to your owner's manual for specific maintenance schedules and guidelines to keep your GMC Yukon XL running smoothly.

How many quarts of oil does the GMC Yukon XL take?
The oil capacity for the GMC Yukon XL varies by engine. The L83 and L86 engines require 8 quarts, while the LM2 diesel engine requires 7 quarts.
How often should I change oil in a GMC Yukon XL?
Oil change intervals can vary, but it's generally recommended to change the oil every 5,000 to 7,500 miles, depending on driving conditions and oil type used. Always consult your owner's manual for specific recommendations.
What is the coolant capacity of the GMC Yukon XL?
The coolant capacity for the GMC Yukon XL varies by engine. For the L83, it ranges from 15.6 to 17.9 quarts, while the LM2 diesel engine requires 21.9 quarts.
Does the GMC Yukon XL need synthetic oil?
While synthetic oil is not mandatory, it is highly recommended for the GMC Yukon XL, especially for optimal performance and protection in extreme temperatures.
What happens if I use the wrong oil viscosity in my GMC Yukon XL?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's crucial to use the recommended 0W-20 viscosity for optimal performance.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks engine operating conditions and calculates when an oil change is necessary. It considers factors like engine temperature and driving habits to provide a timely reminder.
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 performance benefits of synthetic oil. Stick to one type for best results.
How do I know if my GMC Yukon XL has an oil leak?
Signs of an oil leak include visible oil spots under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regular checks can help identify 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 promptly 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 cold, as this allows for a more accurate reading on the dipstick. If the engine has been running, wait a few minutes 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 internals to remove sludge and deposits before adding new oil.
