As part of regular auto maintenance, you should check and change the oil in your car. Routine oil changes are necessary to keep your car running smoothly and efficiently and minimize unnecessary damage, unexpected breakdowns, and expensive repairs.

That said, the frequency of car oil changes can vary greatly depending on many factors, including your car make, model, and year, how you drive, where you drive, and the type of oil you use. This guide highlights the different ways to determine it's time for an oil change.

Check Your Car Owner's Manual

Your car has an owner's manual that contains information on when to change your oil. This booklet provides information about not just oil change intervals but all aspects of your vehicle's servicing needs.

If in doubt about the frequency at which you should change your vehicle's oil, always refer to your vehicle owner's manual for information on the manufacturer-suggested oil change intervals. 

Check Your Car Manufacturer's Website

If you've lost your car owner's manual, you can find it online. All you need to do is to visit the vehicle manufacturer's website, go to the owner's section, and enter details of your specific vehicle's make, model, and year.

Electronic copies of vehicle owner's manuals are usually downloadable, meaning you don't have to go online every time you need to consult your owner's manual.

Check Your Car's Oil Life Monitoring System

Today's car manufacturers recognize the importance of timely car oil changes. If you drive a modern car model, it probably features an oil life monitoring system that allows you to know when your vehicle is due for an oil change.

The system uses data collected by your car's computer to provide an accurate estimate of when you should change your oil. When your oil reaches the end of its life, the system will notify you that it's time for an oil change.

If the oil service light on your car's dashboard illuminates while driving, you should change your oil immediately.

Check With A Trusted Auto Mechanic

If your car doesn't feature an oil monitoring system, a fully trained mechanic can help you determine when to change your oil. They can do this by inspecting the oil to check for signs of deterioration. 

Aside from becoming dirty and changing color, motor oil tends to lose its viscosity or thickness over time. An experienced mechanic can accurately estimate when to get your next oil change by simply inspecting your oil.
