What type of engine oil does the 2006 Buick Lucerne use?

Question

Accepted Answer

According to the manufacturer's specifications, the recommended oil type for the 2006 Buick Lucerne is SAE 5w-30. The engine holds 4.5 quarts or 4.3 liters of oil, which is the amount needed during oil changes. It's important to select the correct oil and look for the API certification seal to ensure it's suitable for all Buick vehicles. While you can choose between conventional and synthetic oil for the car, synthetic oil is more effective as a lubricant and requires less frequent changes. Traditional oil needs to be changed every 3500 miles, while full synthetic can go 5500 to 7000 miles before a new oil and filter are needed.
