Even with an OLS, it's important to keep track of your oil level. 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.

You can also bring in your vehicle and have our service team check the oil level if you’re concerned. You don’t even need to schedule an appointment. 

When the CHANGE ENGINE OIL SOON message displays, service is required for your vehicle as soon as possible. The engine oil and filter must be changed at least once a year, and the OLMS must be reset. The Certified Service experts at your dealer will do this with an oil change in Madison, AL.

If your vehicle is not equipped with an OLMS, consult your Service and Maintenance Schedule contained within your vehicle Owner's Manual for proper change intervals.

Should the engine oil be replaced every 3,000 miles?

Depending on the age of your vehicle, driving habits, and road conditions, your engine may be designed to go longer than 3,000 miles between oil changes. Always be sure to check your engine oil level regularly, even with an OLMS.

Does regularly changing my oil filter help with the life of my engine?

Yes. An oil filter helps ensure your engine is lubricated with clean oil, which is important for optimal engine performance. Both your vehicle’s oil and oil filter should be changed at least as often as recommended by your OLMS and/or Owner’s Manual. 

What are the signs that your oil needs to be changed?

You may not notice any signs that the oil should be changed. However, if you fail to do so, eventually, the engine will stop running as smoothly. For example, the engine may be sluggish and take longer to accelerate.

How much is an oil change in Huntsville, AL?

The cost of an oil change depends on various factors, such as how much oil is needed, the cost of the filter, and the type of oil being used. Synthetic oil is more expensive than regular oil, but it lasts longer. You can contact the service team at Bentley Buick GMC about pricing when you schedule an oil change in Madison, AL.

What happens if you don’t get regular oil changes?

If you don’t get oil changes when recommended by the manufacturer, it will force your engine to work harder. You could end up reducing the life of the engine and needing to have it replaced, which will cost you thousands of dollars.

How do I know what kind of oil I need?

Your owner’s manual will tell you what type of oil to use for your vehicle. You can also talk to our service team at Bentley Buick GMC. The type of oil to use depends on what works best with your vehicle, whether it is warm or cool weather, and what kind of driving you do.
