★ Top Answer
There are three different engine options available for the 2005 GMC Yukon, excluding the Yukon Denali and Yukon XL, which are considered distinct models for practical purposes. Whether you have the 4.8L V8 or one of the 5.3L V8s (regular or Flex Fuel), you will always require 6.0 quarts of SAE 5W-30 full synthetic motor oil. If necessary, you can use SAE 5W-40 as a substitute, although it is not recommended if you can avoid it. This is discouraged because oils with higher viscosities are thicker, which can increase friction in the engine and lead to premature wear and potential early engine failure over time. Despite any potential cost savings, it is always best to stick with SAE 5W-30 for your regular oil changes whenever possible for long-term engine health.

Depending on which engine you have in your 2005 GMC Yukon or Yukon XL, the amount of oil required will vary. For instance, if your 2005 Yukon has the 4.8L V8, 5.3L V8 (non-flex fuel), or 5.3L V8 (flex fuel) engine, you'll need 6 quarts of full synthetic oil. The 2005 Yukon Denali with the 6.0L V8 engine also requires 6 quarts of full synthetic oil. Similarly, the 2005 Yukon XL with the 5.3L V8 (non-flex fuel), 5.3L V8 (flex fuel), or 6.0L V8 engine needs 6 quarts of full synthetic oil. Lastly, the 2005 Yukon XL with the 8.1L V8 engine will need 6.4 quarts of full synthetic oil.
