The 2015 GMC Yukon generally requires Dexos1 Gen 2 synthetic oil, most commonly 0W-20 for the 5.3-liter V8, with an oil capacity of about eight quarts (with filter). Always verify the exact specification in your owner's manual for your trim and climate.
Oil specifications and capacity
GM specifies a Dexos1 Gen 2 motor oil and normally recommends a 0W-20 viscosity for the 2015 Yukon. The following points summarize the standard guidance.

Notes on climate and maintenance
While 0W-20 Dexos1 Gen 2 is the standard recommendation, always consult your owner's manual for any climate-specific exceptions or variations. If you cannot locate Dexos1 Gen 2 0W-20 at your local shop, follow the manual guidance for acceptable alternatives and consult a GM service professional.
