1. Check your owner's manual: This is the most reliable source. It will list the correct part number for your specific vehicle.
2. Look at your current oil filter: The part number is usually printed on the filter itself. You can then use this number to find a replacement at an auto parts store or online.
3. Use an online parts lookup tool: Many websites (like AutoZone, Advance Auto Parts, Napa Auto Parts, etc.) allow you to enter your vehicle's year, make, model, and engine size to find compatible oil filters.
Without knowing the year of your Tahoe, I cannot give you a definitive answer. Providing the year will allow for a precise and safe recommendation.
