The sticker will typically list the recommended gear oil type (e.g., 75W-140, 75W-90) and the amount. Common types include:
* 75W-90: A common choice for many applications, good for a range of temperatures.
* 75W-140: Thicker oil, generally used in heavier applications or hotter climates, or for higher performance. It's more resistant to breakdown under stress.
* Synthetic vs. Conventional: Synthetic gear oil generally offers better performance and protection at both high and low temperatures, but it costs more. Conventional is less expensive but may not perform as well in extreme conditions.
Do not guess. Using the incorrect gear oil can damage your rear axle. Check your owner's manual first, or look for the sticker on the differential cover (usually located on the rear axle). If you can't find the information, consult a Chevrolet dealer or a qualified mechanic.
