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.
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® Synthetic Blend 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.

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
This message will display on your dash when your engine needs an oil change. This message may be displayed if the Oil Life System in your vehicle was not reset during your last oil change.
Heavy smoke from your tailpipe is a strong indicator that oil is being burned within your engine. This can be caused by a number of factors, including bad seals, worn piston rings and more.
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 a problem can save you time and money.
One of the most recognizable and dangerous oil warning signs is smoke coming from your engine. Oil leaking within the engine compartment burns when it drips onto hot engine parts. Leaks of this type should be addressed immediately.
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.

Certified Service technicians at your GM dealer are trained to understand how your vehicle uses its oil and can help keep your vehicle on an appropriate service schedule. They’ll also help you with any questions regarding your OnStar RemoteLink app.

Most vehicles are equipped with the engine Oil Life System (OLS). This system interprets your vehicle’s speed, 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.
Your Certified Service technician will reset your Oil Life System after an oil change. If you would like to reset the system yourself, ask your technician how, or consult your Owner’s Manual if necessary.
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.
**Tire balancing, tax, and more than 5 quarts of oil extra. Most V-6 and V-8 engines and other select vehicles require more than 5 quarts of oil. See participating U.S. dealer for eligible vehicles and details.
