How often should I get an oil change?

Most vehicles have an Oil Life Monitoring System that alerts you when it’s time for an oil change. Learn more about the importance of oil maintenance.

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. 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 are trained to understand how your vehicle uses oil and how it monitors oil life. An oil change from a Certified Service expert not only gives you great service, convenience, and a great price, you also receive the added value of knowing that nobody knows your vehicle better. Head to your Chevrolet, Buick, GMC, or Cadillac Certified Service dealer when it’s time for your vehicle’s next oil change.

CHECKING YOUR OIL LEVEL

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.
 

SELECTING OIL FOR YOUR VEHICLE

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 Mobil1™ Full Synthetic. Certified Service experts will know the right grade of oil to use for your specific vehicle. You can also check your Owner’s Manual for the correct grade.

These oils contain a variety of characteristics that affect your vehicle’s performance, offer varying levels of engine protection, and can extend the time between oil changes.

ENGINE OIL LIFE SYSTEM

Most vehicles are equipped with the engine 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 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.
 

OIL CHANGE WARNING SIGNS

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 will find a number of indicators that will 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 Engine Oil Life System 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 Oil Life System must be reset. The Certified Service experts at your dealer will do this and reset the system.

If your vehicle is not equipped with an Engine Oil Life System, consult your Service and Maintenance Schedule contained within your vehicle 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 engine oil 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.

Oil Leaks

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 is truly an issue can help save you time and money.

VEHICLE MOBILE APP: VEHICLE INFO

With the all-new myChevrolet, myBuick, myGMC, or myCadillac mobile apps, you can monitor vehicle diagnostics information, including fuel range, fuel level, and miles per gallon.

The Oil Life System 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.
