The 2013 Kia Optima’s superb acceleration and spacious cabin make it an excellent daily driver. But like any other vehicle out there, it’s bound to need some repairs over time. You can make the most out of your Kia’s service life if you follow its regular maintenance schedule. Change oil intervals recommended by the manufacturer shouldn’t be ignored to avoid issues early on.
What Type of Oil Does a 2013 Kia Optima Take?


Kia recommends that you buy motor oil with a viscosity of 5W-30 or 5W-40. The model has an oil capacity of 4.6 liters or 4.9 quarts.
What Is the Difference Between Synthetic and Conventional Oil?
Compared to conventional oil, synthetic oil is better able to endure higher temperatures and oil degradation. Additionally, it can lessen engine wear during cold starts. In summary, synthetic oil prolongs engine life, which is why it is frequently suggested for use in modern automobiles.
Drivers in colder climates should use synthetic engine oil since it facilitates cold-engine cranking. It does not undergo the same refining process as motor oils made of petroleum. Instead, several basic stocks are used to create synthetic oil using diverse techniques. The only drawback is that it is more expensive than petroleum-based oils.
Do Motor Oil Brands Matter?


As long as the engine oil adheres to the API specifications established by the manufacturer, you can purchase any brand. To prevent problems in the future, be sure the engine oil you purchase is suitable for your engine.
Recommended Oil Change Interval
Most automakers advise having your oil changed every six months or every 7,500 to 12,000 miles. Kia recommends that you do an oil change every 3,000 to 5,000 miles. You may read up on the recommended oil change schedule for your Kia in your owner’s manual or by getting in touch with the dealership.
Remember that certain variables may have an impact on the oil’s quality. For instance, you may need to get your oil changed every 2,000 to 3,000 miles if you frequently travel through dusty regions or in below-freezing weather.
What Happens When You Don’t Change Your Engine Oil On Time?
Old engine oil won’t effectively lubricate metal components and absorb heat. It may also turn into a thick and dirty sludge, making your engine work double time to fight through the build-up. Your Kia may suffer from major engine issues if you don’t change your oil on time.
