The 2005 Buick Lacrosse typically requires about 4.5 quarts of oil when equipped with a 3.8L V6 engine, including the oil filter change. If your vehicle has a 3.6L V6 engine, it generally needs about 5.5 quarts. Always consult the owner’s manual or check with a dealer for the most accurate specifications.
