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.
What The Certified Service Experts Look For During A Car Inspection
Remaining Engine Oil Life
A quick inspection will determine your vehicle’s remaining oil life percentage (applicable to vehicles with the GM Oil Life Monitoring System). This may be helpful, especially if you are approaching your next oil change.
Your tires are part of what keep your vehicle moving safely down the road. The Certified Service experts check to make sure your tires are properly aligned, balanced, and in top shape. This will help ensure the optimum performance and safety of your tires.
Wiper Blades and Glass Condition
Your wiper blades are essential, especially when it’s raining. The operation and condition of front and rear wipers are checked to make sure they will work well when you need them. A visual inspection of your windshield is completed to check for cracks or chips and the inspection may help prevent further damage down the road if these issues are addressed.
Fluid levels are checked, including the brake reservoir and windshield washer fluid, to be sure they are at optimal levels.
To help keep your brakes performing at their best, an inspection is performed on the condition of your brake system, including lines, hoses, and the parking brake, as well as measurements of the front and rear linings.
Battery Condition and Connections
No one wants to be stuck with a dead battery! A quick battery test will determine the health of your battery, and a visual inspection will check to be sure the battery cables and connections are in top working order.
A brief assessment will make sure you are connected with your OnStar system subscription
Additional Vehicle Inspections
An additional vehicle inspection of critical systems is performed to check for visible leaks that might indicate a concern. The condition of other vehicle components is also visually inspected.
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.
