Owning a Kia Sorento is an amazing experience, but keeping it running smoothly requires more than just putting gas in it. One of the most important aspects of car maintenance is choosing the right engine oil. The right oil can keep your engine in top shape, improve performance, and even help you save money on repairs in the long run. If you've ever wondered, "What type of oil does my Kia Sorento use?" â you're not alone. In this ultimate guide, I'll walk you through everything you need to know to keep your ride running smoothly!

Recommended Oil Types for Kia Sorento
Let's start with the basics. Kia Sorento is a popular crossover SUV that combines power, performance, and practicality. But all of these impressive features won't mean much if the engine isn't well taken care of. That's where engine oil comes in! The type of oil you use plays a huge role in keeping your engine healthy, lubricated, and running at its best. So, what oil should you use for your Kia Sorento? Let's dive into that.
The Basics of Engine Oil
Before we discuss specific oil types for your Kia Sorento, it's important to understand why oil is so crucial. Engine oil serves as the lifeblood of your vehicle's engine, reducing friction and heat while keeping everything running smoothly. It prevents wear and tear on engine parts, cleans the engine by carrying away dirt and debris, and helps protect the engine from corrosion.
There are three main types of engine oil:
- Conventional Oil: This is the most basic type of engine oil. It's made from refined crude oil and works well in a variety of engines, including the ones in most Kia Sorento models.
- Synthetic Oil: This oil is chemically engineered and offers superior performance. It can handle higher temperatures and pressures better than conventional oil, making it perfect for high-performance engines or extreme driving conditions.
- Synthetic Blend Oil: This oil combines synthetic and conventional oils, offering a balance of performance and cost. It's a good option if you want some of the benefits of synthetic oil without the high price tag.
What Oil Does a Kia Sorento Use?
Now, let's get to the meat of the matter! Kia recommends using 5W-30 engine oil for most Kia Sorento models. This is a multi-viscosity oil, which means it works well in both hot and cold temperatures. The “5W” refers to the oil's low-temperature viscosity, while the “30” refers to its high-temperature viscosity. The 5W-30 oil helps ensure smooth engine performance whether you're starting up your car on a chilly morning or driving under the hot sun.
Kia also recommends using synthetic oil for its newer models, as it offers better protection and longer-lasting performance. It's a little pricier than conventional oil, but the benefits are worth it in the long run. If you have an older Sorento, you can still use conventional oil, but synthetic oil is always a safer and more efficient choice.
Oil Capacity
The amount of oil your Kia Sorento needs depends on the engine size. Most Kia Sorento models come with a 2.4L 4-cylinder or a 3.3L V6 engine. Here's how much oil you can expect to need:
- 2.4L 4-Cylinder Engine: 4.5 quarts of oil
- 3.3L V6 Engine: 5.1 quarts of oil
It's always a good idea to check your owner's manual or consult with your mechanic to ensure you’re using the correct oil capacity for your specific model.
Choosing the Right Oil Based on Model Year
Choosing the right oil also depends on the year of your Kia Sorento. Over time, engine technology has improved, and so has the oil used to keep it running. Here's a quick breakdown of the recommended oils for different model years of the Kia Sorento.
2011-2016 Kia Sorento
For the older Sorento models (2011-2016), you'll want to use 5W-30 motor oil. Synthetic oil is recommended for the 2013-2016 models, but the 2011-2012 models can get by with conventional oil if you’re on a budget. For the 2.4L 4-cylinder engine, you'll need 4.5 quarts of oil, while the 3.5L V6 engine requires around 5.1 quarts.
2017-2020 Kia Sorento
The 2017-2020 Kia Sorento models continue to use 5W-30 motor oil, but with a stronger recommendation for synthetic oil. These newer models come with improved engine components that can withstand higher temperatures and stresses, making synthetic oil the best option. The oil capacity remains the same for the 2.4L 4-cylinder engine (4.5 quarts) and the 3.3L V6 engine (5.1 quarts).
2021-Present Kia Sorento
With the 2021 Kia Sorento, the recommended oil type remains 5W-30 synthetic oil, but there is one change: some 2021 models now have the 2.5L 4-cylinder turbocharged engine. This engine requires 5W-30 synthetic oil, and the oil capacity for this engine is about 5.1 quarts, similar to the V6 engine in earlier models. Overall, synthetic oil remains the top choice for this generation, offering superior performance and longevity.
Why Does the Model Year Matter?
As you can see, the oil recommendations are consistent over the years, with only minor adjustments for newer models. That said, it's important to use the oil specified for your model year to avoid damaging your engine. The newer models are designed to run on synthetic oil, which is formulated to offer better protection, especially in high-temperature or high-performance situations. On the other hand, older models can still run well with conventional oil if that’s what you prefer.
How to Change the Oil in a Kia Sorento
Changing the oil in your Kia Sorento is one of the most important maintenance tasks you can do to keep your engine running smoothly. If you're not sure how to do it, don't worry! Changing your oil isn't as difficult as it sounds, and with the right tools and a little patience, you can do it yourself.
Tools You'll Need
Before you start, gather all the necessary tools and supplies. You'll need:
- New engine oil (5W-30 synthetic or conventional, depending on your model year)
- Oil filter
- Oil drain pan
- Socket wrench
- Funnel
- Car jack and jack stands (if needed)
Steps to Change the Oil
- Prepare the Car: Park your Kia Sorento on a flat, level surface. Turn off the engine and allow it to cool for about 10 minutes. Then, jack up the car (if needed) and place it on jack stands for safety.
- Drain the Old Oil: Place the oil drain pan underneath the oil pan. Use a socket wrench to remove the oil drain plug and allow the old oil to drain into the pan. Be sure to let it drain for several minutes to get all the oil out.
- Replace the Oil Filter: Using your socket wrench, remove the old oil filter. You may need to use an oil filter wrench if it's on too tightly. Install the new oil filter by hand, making sure it's snug, but not too tight.
- Add the New Oil: Once the old oil has drained and the filter is replaced, it's time to add the new oil. Use a funnel to pour the new oil into the oil fill cap located on top of the engine. Add the recommended amount of oil based on your engine size (usually 4.5 to 5.1 quarts).
- Check the Oil Level: After adding the oil, wait a few minutes and then check the oil level using the dipstick. Insert the dipstick, remove it, wipe it clean, and reinsert it. Pull it out again to check the oil level. Add more oil if needed until it reaches the “full” line.
- Finish Up: Once you've checked the oil level, replace the oil fill cap and tighten it. Dispose of the old oil and filter properly by taking them to a local recycling center. Lower the car from the jack stands, and you're done!
Why Regular Oil Changes are Important
Changing your oil regularly is crucial to keep your engine running smoothly. Oil naturally breaks down over time, losing its ability to lubricate the engine effectively. Dirty oil can lead to increased friction and wear on engine parts, which can cause serious damage. Regular oil changes help ensure that your engine stays clean, well-lubricated, and performing at its best.
I hope you've learned all the ins and outs of the best oil for your Kia Sorento. By using the right oil and changing it regularly, you can keep your car running for years to come and avoid costly engine repairs.
