Chevrolet suggests using 5w-30 synthetic motor oil in your 2005 Tahoe. You'll need 6 quarts for an oil change. Synthetic oil is superior for optimal performance as it reduces engine friction and includes cleaning additives that help eliminate deposits. It burns cleaner, thickens more slowly, and produces fewer deposits. It is recommended to change your oil every 7,500 miles to extend engine life, enhance gas mileage, and boost performance. You can do the oil change yourself; just remember to replace the oil filter as well.

Wal-Mart's Super Tech oil is a budget-friendly option that works well. I make sure to swap out the oil and filter every 5000 miles.
Okay, Chevrolet suggests using a 5w-30 synthetic oil.
