Oil Life System
Many of today’s vehicles are equipped with an Oil Life Monitoring System (OLMS). 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 OLMS 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, 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 OLMS must be reset. The Certified Service experts at your dealer will do this.
If your vehicle is not equipped with an OLMS, consult your Service and Maintenance Schedule contained within your vehicle Owner's Manual for proper change intervals.
Frequently Asked Questions
Q: Should the engine oil be replaced every 3,000 miles?
A: Depending on the age of your vehicle, driving habits, and road conditions, your engine may be designed to go longer than 3,000 miles between oil changes. Always be sure to check your engine oil level regularly, even with an OLMS.
Q: Does regularly changing my oil filter help with the life of my engine?
A: Yes. An oil filter helps ensure your engine is lubricated with clean oil, which is important for optimal engine performance. Both your vehicle’s oil and oil filter should be changed at least as often as recommended by your OLMS and/or Owner’s Manual.
