2019 Kia Optima 2.4 Engine Oil Capacity

The Importance of Regular Engine Oil Changes for Your 2019 Kia Optima 2.4

Your Kia Optima Journey

Owning a Kia Optima is all about enjoying the journey, but without proper engine oil maintenance, that enjoyment will be short-lived. That’s why regular engine oil changes are a must! The good news is, you can save money by performing oil changes right at home.

Discovering Your Optima’s Engine Oil Capacity

Before you get started, it’s important to know the engine oil capacity of your 2019 Kia Optima 2.4. This model, equipped with a 2.4-liter engine, requires 4.3 quarts (or 4.0 liters) of engine oil.

It’s essential to note that the engine oil capacity should not be confused with the engine’s displacement. The 2.4 liters of space that your Optima’s engine takes up under the hood is not the same as the amount of oil it needs to run smoothly. Always refer to the correct oil capacity to ensure optimal performance.

Choosing the Right Oil for Your Optima

Now that you know how much oil your Optima needs, let’s talk about the type of oil that is recommended for your 2019 Kia Optima 2.4. According to the manufacturer, your Optima requires premium grade 5W-20 engine oil.

The oil grade numbers refer to the oil’s viscosity, which indicates how thick or thin it is at a given temperature. In the case of 5W-20 oil, it has low viscosity, meaning it stays relatively thin at both cold and hot temperatures. This type of oil reduces wear and tear on your engine and performs well in cold weather conditions.

If you prefer to use synthetic oil, Kia states that you can opt for a high-quality synthetic oil blend as long as it meets the same requirements. So, if you find premium-grade 5W-20 synthetic oil, you can confidently use it in your 2019 Optima.

When to Change Your Optima’s Engine Oil

Knowing when to change your engine oil is crucial for the optimal performance of your 2019 Kia Optima 2.4. Kia recommends changing the oil every 3,000 to 5,000 miles if you’re using conventional oil. If you’re using synthetic oil, you can go longer between changes, typically around 7,500 to 10,000 miles.

However, it’s important to keep an eye out for signs that indicate the need for an oil change, regardless of mileage. These signs include:

– Dark brown or black color of the oil
– Coarse or gritty texture of the oil
– Strange noises coming from the engine
– Unpleasant odors like oil, smoke, or burning
– Changes in your vehicle’s performance

If you notice any of these signs, it’s essential to change your oil promptly to maintain the health of your Optima’s engine.

How to Perform an Oil Change on Your 2019 Kia Optima 2.4

Gather Your Materials

To perform an oil change on your 2019 Kia Optima 2.4, you’ll need the following materials:

– Socket wrench
– Filter wrench
– Drain pan
– Replacement filter and washer
– 4.3 quarts of 5W-20 motor oil

The Step-by-Step Process

3. Remove the oil fill cap.

4. Position yourself underneath the engine and use the socket wrench to remove the oil drain bolt and washer. Allow the old engine oil to drain into the drain pan.

6. Install the new oil filter.

7. Replace the oil drain bolt with a new washer.

8. Refill the engine with 4.3 quarts of fresh 5W-20 motor oil.

9. Replace the oil fill cap.

10. Start your car for about 30 seconds to allow the fresh oil to circulate.

11. Clean up: Remember to dispose of the dirty engine oil properly by placing it in a sealed container and bringing it to your local recycling center.

Always refer to your owner’s manual for specific instructions related to your model, but generally, following these steps will ensure a successful oil change for your 2019 Kia Optima 2.4.

Frequently Asked Questions about Engine Oil for the 2019 Kia Optima 2.4

1. Does using synthetic oil improve the performance of my 2019 Kia Optima 2.4?

Using synthetic oil can enhance the performance of your Optima’s engine. It offers better lubrication, improved protection against heat and wear, and increased fuel efficiency. If you choose to use synthetic oil, make sure it meets the recommended specifications (premium-grade 5W-20) for your Optima.

2. Can I use a different oil grade for my 2019 Kia Optima 2.4?

It is best to stick to the manufacturer’s recommendations when it comes to oil grade for your Optima. Using a different oil grade may affect the engine’s performance and could potentially void your warranty. Stick to premium-grade 5W-20 oil for optimal results.

3. How often should I check my engine oil level?

It is recommended to check your engine oil level at least once a month or before long trips. This will help you ensure that the oil level is within the recommended range and avoid potential engine damage due to low oil levels.

4. Can I reuse the oil filter during an oil change?

It is generally not recommended to reuse an oil filter during an oil change. Oil filters are designed to capture contaminants and debris, and over time, they become clogged. Replacing the oil filter ensures that your engine is properly protected and receives clean oil.

5. How do I dispose of the old engine oil?

Properly disposing of old engine oil is crucial for environmental safety. Place the old oil in a sealed container, such as the one the new oil came in, and take it to your local recycling center or an authorized oil collection facility. Do not dump it in the garbage or pour it on the ground.

Remember, regular engine oil changes are essential for the longevity and optimal performance of your 2019 Kia Optima 2.4. By following the recommended guidelines and performing oil changes as needed, you can enjoy a smooth and enjoyable journey in your Optima for years to come.
