The 2006 Cadillac STS requires 5.7 liters (6.02 quarts) of SAE 5W-30 engine oil, a popular synthetic fluid suitable for various engines in most weather conditions. Your car has an oil light reminder to indicate when maintenance is due, which needs to be reset after an oil change. You can easily reset the light yourself if you do the oil change or if your mechanic forgets. Cadillac suggests changing the oil every 7,500 miles or 6 months, depending on which comes first. Your maintenance schedule should also consider your local climate and driving habits. The average cost for an oil change for the 2006 STS is between $120 and $140, with labor making up around $50 of that total.
The ideal oil viscosity for the 2006 Cadillac STS is 5w-30 synthetic motor oil.
