Ask our experts which grade is best for your vehicle. You may also refer to your Owner's Manual for more information.
Oil Life System
Many of today's vehicles are equipped with an 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 monitors a number of conditions, including engine revolutions, engine temperature, and miles driven to let you know precisely when to come in for an oil change. As soon as you notice your vehicle's OLS light illuminate, you will know it's time for service.
Checking your oil level
Even with an OLS, it's important to keep track of your oil level. 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.
Oil change warning signs
When the CHANGE ENGINE OIL SOON message displays, service is required for your vehicle as soon as possible. The engine oil and filter must be changed at least once a year and the OLS must be reset. The Certified Service experts at your dealer will do this.
If your vehicle is not equipped with an OLS, consult your Service and Maintenance Schedule contained within your vehicle Owner's Manual for proper change intervals.
