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.
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.
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.
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.
Vehicle apps† (myChevy, myBuick, myGMC, myCadillac) are available on select iOS, Android™, BlackBerry® and Windows® devices. Services vary by device, vehicle, and conditions.

A: When the “Change Engine Oil Soon” message displays, oil change service is necessary for the vehicle as soon as possible, within the next 600 miles.
If driving under the best conditions, the Engine Oil Life System might not indicate the need for vehicle service for more than a year. The motor oil and filter must be changed at least once a year and the Engine Oil Life System must be reset. Your dealer has trained service technicians who will perform this work and reset the system. Click here to locate a dealer near you.
A: Choosing the proper grade of oil is a critical step in engine maintenance. From conventional to full synthetic, your Certified Service experts offer a range of oil types, including ACDelco Conventional Oil, ACDelco dexos1™ Full Synthetic, and Mobil 1™ Full Synthetic. Ask the experts which grade of oil you should use for your specific model. You can also check your Owner’s Manual for the correct grade.
A: The majority of today’s Chevrolet, Buick, GMC, and Cadillac vehicles are equipped with the Engine Oil Life System which has made the 3,000-mile oil change obsolete. Depending on the age of the vehicle, driving habits, and road conditions, vehicles with today’s advanced engines can go much longer than 3,000 miles between oil changes. Always be sure to check your motor oil level regularly, even with an Engine Oil Life System.
