I believe changing the oil and oil filter uses 2.7 quarts, and just changing the oil uses 2.5 or 2.6 quarts. There has been lots of discussion about this because dealers almost always overfill (well above the top fill line) because they dump in three full quarts, not to mention often using regular bulk oil they have at the shop. Most everyone uses Mobile 1 synthetic, 0W-20 or 5W-20 if your shop is out of 0W-20 which they stopped making recently.
