Check your owner's manual. The manual will specify the recommended oil viscosity (like 5W-30, 10W-30, etc.) and API certification (like SM, SN, etc.). The Exxon XD-3 10W-30 likely meets many specifications, but you need to confirm it meets *your* Tahoe's requirements.
Using the wrong oil viscosity can negatively impact engine performance and longevity. Using oil that doesn't meet the required API specifications could void your warranty (if applicable) or cause engine damage.
In short: Don't rely on internet advice for this. Consult your owner's manual.
