OIL CHANGE & ENGINE OIL LIFE SYSTEM
HOW OFTEN SHOULD I GET AN OIL CHANGE?
Most vehicles have an Engine Oil Life Monitoring System (OLS) that alerts you when it’s time for an oil change. Consult your Owner’s Manual for more information on the OLS specific to your vehicle.
If your engine is the heart of your vehicle, oil is its lifeblood. Driving around with dirty oil — or not enough oil — can shorten the life of your engine considerably. Over time, repeated heating and cooling as well as the accumulation of particles can make oil thicker. Not only can this decrease its ability to flow (also known as viscosity), it can leave harmful deposits in your engine and cause extensive damage. That’s why GM Genuine Parts and ACDelco parts offer both Original Equipment and Gold-tier (Professional) oil options to support and protect your engine.
Chevrolet, Buick, GMC, and Cadillac Certified Service technicians undergo extensive hours of training in order to better understand how your vehicle uses oil and how to service it. An oil change from an expert Certified Service technician not only gives you great service, convenience, and a great price, you also receive the added value of knowing that nobody else knows your vehicle better.
Keeping an eye on oil level and other measures of your engine’s oil is critical. Lack of proper engine oil maintenance can damage the engine. Below, you’ll find a number of indicators to help you prevent damage to your engine.
CHANGE ENGINE OIL SOON
When the CHANGE ENGINE OIL SOON message displays, service is required for your vehicle as soon as possible within the next 600 miles. If driving under the best conditions, the OLS might not indicate the need for vehicle service for more than one year. The engine oil and filter must be changed at least once a year and the OLS must be reset.
If your vehicle isn’t equipped with an OLS, consult your Service and Maintenance Schedule contained within your vehicle’s Owner’s Manual for proper change intervals.
OIL PRESSURE LOW/STOP ENGINE
Low engine oil pressure can cause extreme and costly damage to your engine. If this message displays, safely bring your vehicle to a stop and do not restart your engine until the proper pressure is restored and the cause of the drop is corrected. You should check the oil level immediately. DO NOT operate the engine with the oil pressure warning light on or an ENGINE OIL LOW ADD OIL message displayed.
One of the most immediate signs of an issue with your oil is noticeable leaks. If you detect a leak, address it with your dealer as soon as possible. Catching a problem before it’s truly an issue can help save time and money.
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.

Most vehicles are equipped with an 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. When the OLS light comes on, you know it’s time for service. It’s an accurate, effective way to save money and help reduce oil waste.
To find out more about the OLS, consult your Owner’s Manual.
With the myChevrolet, myBuick, myGMC, or myCadillac apps, you can monitor vehicle diagnostic information, including fuel range, fuel level, and miles per gallon. You can also keep track of oil life and tire pressure, access vehicle features remotely, and manage account information all from your smartphone.
The OLS tells you precisely when it's time to change your oil, based not only on your driving patterns and mileage, but also things like the climate of your area. This means that changing your oil every 3,000 miles may no longer be necessary. Certified Service technicians at your Chevy, Buick, GMC, and Cadillac dealer are trained to understand how your vehicle uses its oil and can help keep your vehicle on an appropriate service schedule.
