The 2018 GMC Yukon has a couple of engine options available and whether You have the 5.3 L V8 or 6.2 L V8 You will need 8 quarts of SAE 0W-20 viscosity oil. You'll want to make sure the oil You choose has a Dexos approved logo on it because if You use another type of oil and it ends up causing damage to Your vehicle it will not be covered by Your warranty. Fortunately it's very easy to find these and the more popular brands like Mobil 1, Castrol, and Valvoline will all work well for You. Keep in mind to purchase a compatible oil filter for every oil change as well and the GM part number for one is 19330000. -
