What you need to know before changing your Kia's oil
A Kia oil change follows the same basic steps as any other car, but the location of the drain plug, filter, and fill cap varies by model year and engine size. Most Kias need an oil change every 3,000 to 10,000 miles, depending on whether you use conventional or synthetic oil and what your owner's manual says for your specific year. The manual is the only source that matters for your vehicle — it tells you the exact oil type, capacity, and interval your engine was designed for.
You'll need an oil drain pan, a wrench or socket to remove the drain plug, an oil filter wrench, fresh oil in the correct grade, and a new oil filter. If you're doing this yourself, you also need a safe way to lift the car or access the underside — jack stands are essential if you're using a jack. Many people choose to have a shop do this work instead, which costs between $30 and $75 depending on the oil type and your location.
Key Takeaways
- Check your Kia's owner's manual for the exact oil type, capacity, and change interval for your model year and engine.
- The drain plug is usually on the bottom of the engine; you'll need a wrench, drain pan, and new filter to complete the job.
- Conventional oil typically requires a change every 3,000 to 5,000 miles, while synthetic oil can go 7,500 to 10,000 miles between changes.
- If you lift your car, always use jack stands — never rely on a jack alone to hold the vehicle while you work underneath.
- After draining old oil and replacing the filter, refill with the correct amount and type of oil, then check the level with the dipstick or electronic gauge.
Finding the drain plug and filter on your Kia
The oil drain plug is located on the bottom of the engine pan and is usually a bolt that you turn counterclockwise with a wrench or socket. On most Kias, it's accessible from underneath the vehicle, though some models require you to remove a plastic undertray first. The undertray is typically held on by a few plastic clips or bolts and slides out once those are removed.
The oil filter sits on the side of the engine and looks like a cylindrical canister. On most Kias, you can reach it from above or the side without removing much else. Use an oil filter wrench — a metal band or socket-shaped tool — to turn it counterclockwise and unscrew it by hand once it's loose. The filter will still contain old oil, so position your drain pan underneath before you remove it.
The step-by-step process for draining and refilling
Start by warming up the engine for a minute or two — warm oil flows faster and drains more completely than cold oil. Turn off the engine and let it cool just enough that you can work safely. Place your drain pan under the drain plug, then use your wrench to turn the plug counterclockwise. Once it's loose enough, unscrew it by hand and set it aside in a safe place where you won't lose it.
Let the old oil drain completely into the pan — this usually takes 5 to 10 minutes. While you wait, use your oil filter wrench to remove the old filter. Wipe the filter mounting surface clean with a rag, then explore a thin layer of new oil around the rubber gasket of the new filter. Screw the new filter on by hand until the gasket touches the engine, then turn it an additional three-quarter turn — do not over-tighten.
Once the old oil has finished draining, wipe the drain plug clean and screw it back in by hand, then tighten it with your wrench. Don't over-tighten — you want it snug, not crushed. Now pour the new oil into the fill cap on top of the engine. Your owner's manual tells you exactly how much to add; most Kias hold between 3.5 and 5.5 quarts depending on the engine.
Checking your oil level after the change
After you've added oil, wait a minute for it to settle, then check the level. Older Kias have a traditional dipstick — pull it out, wipe it clean, reinsert it fully, then pull it out again to read the level. Newer models have an electronic oil level display in the dashboard; consult your manual for how to access it. The oil should be at the "full" mark on the dipstick or show "full" on the display.
If the level is low, add a small amount of oil and check again. If it's overfilled, you'll need to drain a little out through the drain plug. Start the engine and let it run for 30 seconds, then turn it off and wait a minute before checking the level again — this allows the new oil to circulate through the engine and filter.
Oil type and change intervals for different Kia models
Kia's recommendations vary by model year and engine. Older Kias and those with conventional engines often require a change every 3,000 to 5,000 miles using conventional oil. Many newer Kias can go 7,500 to 10,000 miles on synthetic oil, and some recent models are rated for even longer intervals. Your owner's manual is the only reliable source for your specific vehicle — the interval printed there is what your engine was tested and designed for.
The oil grade matters just as much as the interval. Most Kias use 0W-20 or 5W-30, but some engines call for different weights. Using the wrong grade can affect fuel economy, engine performance, and long-term wear. The manual lists the correct grade on a sticker inside the driver's door jamb as well as in the owner's manual itself.
Disposing of old oil safely
Never pour old oil down a drain or into the ground — it contaminates water supplies and harms wildlife. Most auto parts stores that sell oil will take used oil for free, even if you didn't buy it from them. Some gas stations and quick-lube shops also accept it. Call ahead to confirm they take used oil, then bring it in a clean container or the drain pan you used.
If you have used oil filters, many recycling centers and auto parts stores will take those too. Some charge a small fee, usually under $1 per filter. Check with your local waste management or recycling program for drop-off locations near you.
When to have a shop do it instead
If you don't have a safe way to lift your car, don't have the right tools, or aren't comfortable working underneath a vehicle, a shop is the better choice. A quick-lube facility or your Kia dealer can complete an oil change in 20 to 30 minutes. The cost is usually $30 to $75 depending on whether you choose conventional or synthetic oil and your location. Shops also dispose of the old oil for you, which saves a trip to the recycling center.
Some people prefer to have a shop handle it because they can verify the work was done correctly and get a receipt for their records. If your Kia is still under warranty, check whether the manufacturer requires oil changes to be done at a dealer — some warranty terms depend on this.
Frequently Asked Questions
How do I know if my Kia needs an oil change?
Most Kias have an oil change reminder light on the dashboard that comes on when the interval is due. You can also check your owner's manual for the mileage interval and mark your calendar. Some newer Kias calculate the interval based on driving conditions and show a percentage remaining on the display instead of a fixed mileage number.
Can I use a different oil grade than what the manual says?
No — use only the grade specified in your owner's manual. Using a thicker or thinner oil can reduce fuel economy, affect engine performance, and potentially void your warranty. The manual lists the correct grade for your engine's design and climate.
What should I do with the old oil filter?
Most auto parts stores and recycling centers will take used oil filters for free or a small fee. Some require you to drain the oil from the filter first by letting it sit upside down over a pan for a few hours. Call ahead to ask what your local facility requires.
Do I need to replace the drain plug every time?
No — the drain plug is reusable. Wipe it clean and screw it back in. However, if the threads are stripped or the plug is damaged, you'll need a new one, which costs $5 to $15 depending on your Kia model.
What if I overfill the oil?
Overfilled oil can damage the engine by creating excess pressure and causing oil to leak past seals. If you've added too much, drain a small amount through the drain plug until the level is correct. Check the level again after the engine has run for a minute.
