How do I know if my Kia Stonic needs an oil change?

I bought a used Kia Stonic and I'm not sure when the last oil change was done. How can I tell if it needs to be changed?

First, check your owner's manual to see when the oil change is recommended for your specific model. If you don't have a manual, you can usually find one online. You can also look at the color and level of your oil. If it's black and low, it's time for a change.

You can also keep track of your mileage since the last oil change. Most Kia Stonic models need an oil change every 7,500 to 10,000 miles. If you've reached this mileage, it's definitely time for an oil change.

Another way to tell is by using an oil checker tool. These can be purchased at most auto shops and are a quick and easy way to test the quality of your oil.
