The 2006 Buick LaCrosse comes with two engine options: a 3.6 L V6 requiring 5.5 quarts of oil with a filter, and a 3.8 L V6 needing 4.5 quarts with a filter. The recommended oil for optimal performance is SAE 5W-30 Synthetic for all temperatures, or 0W-30 in temperatures below -20°F. The 3.6 L V6 requires a drain plug torque of 18 ft/lbs, while the 3.8 L V6 engine needs 22 ft/lbs. Regular oil changes every 7,500 miles or when the oil life indicator comes on are crucial to keep the engine clean and properly lubricated.
The 2006 Buick LaCrosse requires around 4.5 quarts of oil when changing the filter. It should use Synthetic Blend Motor Oil with a viscosity grade of SAE 5W-30.
