The Yukon with the 5.3-liter V8 typically requires 6 quarts (about 5.7 liters) of engine oil when performing a full oil change with a new filter.
In practice, GM lists the capacity as 6 quarts with a new filter. If you drain the oil but do not replace the filter, the amount you add may be closer to 5 quarts, but you should verify the level with the dipstick after refilling and adjust as needed. Always use the oil grade and specifications recommended by GM for your exact model year.
Capacity and recommended practice
Before listing the typical numbers, note that the official GM specification for the 5.3L V8 in this era is 6 quarts when a fresh filter is used. Here are the practical figures you should expect during routine service:
- With a new oil filter: 6 quarts (5.7 liters)
- Without replacing the filter (draining only): about 5 quarts (4.7 liters)
After performing an oil change, start the engine, let it run briefly, then recheck the level on the dipstick and top off to the full mark if necessary.
Oil type and maintenance notes
Recommended oil specification
Use 5W-30 engine oil that meets GM dexos1 specification. Synthetic or synthetic-blend oils are commonly used, but always adhere to the owner's manual guidance and consider climate and driving conditions when choosing between conventional and synthetic formulas. If your Yukon is Flex-Fuel, the oil capacity remains the same regardless of fuel type.
Summary
For a 2008 GMC Yukon with the 5.3L V8, plan on about 6 quarts (roughly 5.7 liters) of engine oil with a new filter during a full oil change, using 5W-30 oil that meets the dexos1 specification. Always confirm with the owner's manual and check the dipstick after refilling.
