GMC Yukon
Data verified by Nick Marchenko, PhD
Maintaining your GMC Yukon's engine oil is crucial for optimal performance and longevity. Depending on the model year and engine option, the GMC Yukon features a variety of engines, including the L31 (5.7L V-8), L83 (5.3L V-8), L86 (6.2L V-8), and LM2 (3.0L I-6 diesel) from 1999 to 2022. For instance, the L31 engine requires 5 quarts of 5W-30 oil, while the L83 and L86 engines typically need 8 quarts of 0W-20 oil. It's important to also consider the coolant capacities, which range from 13.2 quarts for the LR4 (4.8L V-8) to 21.9 quarts for the LM2 diesel engine.
Regular oil changes are essential to keep your GMC Yukon running smoothly. Using the correct oil viscosity and capacity ensures that your engine operates efficiently and minimizes wear. For example, the L92 and L94 engines utilize 6 quarts of 5W-30 oil, while the LM7 engine also requires 6 quarts of the same viscosity. Always refer to your owner's manual for specific recommendations based on your engine type and model year.

How many quarts of oil does the GMC Yukon take?
The oil capacity for the GMC Yukon depends on the engine. The L31 engine takes 5 quarts, while most L83 and L86 engines require 8 quarts. The LM2 diesel engine has an oil capacity of 7 quarts.
How often should I change oil in a GMC Yukon?
It's generally recommended to change the oil in your GMC Yukon every 5,000 to 7,500 miles, depending on the engine type and driving conditions. Always consult your owner's manual for specific intervals.
What is the coolant capacity of the GMC Yukon?
Coolant capacity varies by engine in the GMC Yukon. For example, the LR4 (4.8L V-8) has a coolant capacity of 13.2 quarts, while the LM2 diesel engine can hold up to 21.9 quarts.
Does the GMC Yukon need synthetic oil?
While synthetic oil is not mandatory, it is recommended for many GMC Yukon engines, particularly the L83 and L86, which benefit from the enhanced protection and performance that synthetic oil provides.
What happens if I use the wrong oil viscosity in my GMC Yukon?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's essential to use the recommended viscosity for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks your engine's oil condition and provides alerts when it's time for an oil change. It considers factors like engine temperature, driving habits, and mileage.
Can I mix synthetic and conventional oil?
While it's technically possible to mix synthetic and conventional oil, it's not recommended as it can reduce the effectiveness of the synthetic oil's performance. It's best to stick with one type.
How do I know if my GMC Yukon has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a burning smell, or an oil pressure warning light on the dashboard. Regularly checking your oil level can also help identify leaks.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn engine components, such as piston rings or valve seals, or by using the wrong oil viscosity. Regular maintenance can help mitigate these issues.
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 provide a more accurate reading on the dipstick.
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 cleans the engine by removing sludge and deposits. Flushing is not always necessary and should be done according to manufacturer recommendations.
