For a 2007 Yukon XL, the front and rear differentials typically require 75W-90 gear oil, which is suitable for most driving conditions. It's important to use a high-quality synthetic or conventional gear oil that meets the specifications outlined in the owner's manual. Additionally, if the vehicle is equipped with an Eaton G80 locking differential, ensuring the fluid contains the appropriate additives is essential for optimal performance. Always check the owner's manual for specific recommendations and capacities.
