You start your GMC and the dash says Change Engine Oil Soon. It isn't obvious whether "soon" means this week or this month.
Or the message hasn't appeared at all, and you're wondering how long you can wait before your next GMC oil change.
An oil and filter change is recommended every 7,500 miles, and most GMC vehicles have an oil life system that estimates remaining oil life from how you drive. When the Change Engine Oil Soon message appears, schedule the change within the next 600 miles. Whatever the system shows, the oil and filter must be changed at least once a year.
The system tracks things like your speed and engine temperature, so the miles between changes differ from one driver to the next. If you drive to Smyrna and back every workday, you can cover 600 miles in a few weeks, so book soon after the message appears.
The Change Engine Oil Soon message is the main signal, and several other messages and situations call for action too.
| What you notice | What it can suggest | Best next step |
|---|---|---|
| The Change Engine Oil Soon message appears | The oil life system estimates that your oil is due for a change. | Schedule an oil and filter change as soon as possible, within the next 600 miles. |
| Your last oil change was about a year ago and no message has appeared, which can happen if you drive few miles, such as short trips around the Middle Tennessee State University campus | The one-year limit applies even when mileage hasn't triggered the message. | Change the oil and filter, and have the oil life system reset. |
| Your GMC doesn't have an oil life system | Your owner's manual sets the interval, and oil also breaks down with time. | Follow the owner's manual interval, and change the oil about once a year even if you haven't reached that mileage. |
| Oil spots or drips where you park | An oil leak, which can lower the oil level in the engine. | Schedule service soon so the source can be found. |
| An ENGINE OIL LOW ADD OIL message | The oil level is low, and the engine shouldn't be operated with this message displayed. | Check the level and add oil before you drive any farther. |
| The Oil Pressure Low/Stop Engine message | Low oil pressure, which can damage the engine. | Safely bring the vehicle to a stop, don't restart the engine, check the oil level, and contact us. |
No. If the Oil Pressure Low/Stop Engine message appears, safely bring your vehicle to a stop and don't restart the engine. Running the vehicle with low oil pressure can damage the engine.
Check the oil level, and contact us for service. Keep the engine off until the cause of the pressure drop has been found and corrected.
On a GMC with a dipstick, check the level with the engine off and the vehicle on level ground. A cold engine that has been off for about two hours gives a more accurate reading. Some newer GMC trucks have no dipstick and show the oil level on a screen instead, so check your owner's manual for how to read it.
If an ENGINE OIL LOW ADD OIL message appears, the oil level is low. Check the level and add oil before you drive any farther, because the engine shouldn't be operated with that message displayed.
