Most Buick vehicles are equipped with the engine Oil Life System (OLS). This system interprets your vehicle’s speed and engine temperature and continuously monitors operating conditions—which helps determine when it’s time for an oil change.


The OLS also monitors your personal driving habits and the area’s climate conditions to let you know precisely when to come in for an oil change. As soon as the OLS light comes on, you know it’s time for service. It’s a simple, effective way to save money and help reduce oil waste.


Your Certified Service technician will reset your Oil Life System after an oil change. If you would like to reset the system yourself, ask your technician how, or consult your Owner’s Manual.



It’s a good idea to periodically check your oil level. In order to get an accurate reading, the oil must be warm, at normal operating temperature, and the vehicle must be on level ground. Always consult your Owner’s Manual for the proper procedure to check your oil level. You’ll get a more accurate dipstick reading by following those instructions.
