Notice to Our Loyal Service Customers Regarding Your Kia Warranty And Kia’s New Synthetic Oil Requirement
All Kia vehicles built after April 2021 must now use 100% synthetic oil in order to remain protected by factory warranty. Any vehicle that is still covered by a factory warranty after June 2022 will need to use full-synthetic oil to stay protected. Your guarantee may be void if conventional or semi-synthetic oil is used.
Definition of 5w20 Vs. 5w30
The engine oil type 5w20 is distinguished by its oil weight of 20 in warm weather and a winter grade of 5. It has a lower viscosity than 5w30. While 5w30 has the same viscosity rating of 5 in the winter, it has an oil weight of 30 in the summer, making it thicker.
Working conditions for 5w20 Vs. 5w30
For use in cooler climates, use 5w20. As it moves swiftly and smoothly to deeper engine components with less friction, it makes it possible for a vehicle’s engine to start up rapidly. It immediately lubricates the components. In contrast, 5w30 performs well in warm environments. Unlike 5w20, it does not thin out quickly when exposed to heat. The engine components are therefore better protected overall when using 5w30 at operational temperatures.
Performance of 5w20 Vs. 5w30
These two engine oils function well in the environments for which they were created. Due to its low viscosity and reduced friction in the engine parts, 5w20 is a champion in colder regions with speedier engine starts. In hotter regions where a thick oil is required to resist the higher temperatures, 5w30 excels. Naturally, the engine will heat up more, necessitating a thicker oil. In colder climates, 5w20 is associated with higher performance and fuel economy, whereas 5w30 is associated with better overall engine component protection.

Can I substitute 5W 30 with 5W 20?
It is generally not advised to substitute 5w30 oil (or any other oil weight) for 5w20 oil because even a small viscosity change has the potential to harm your engine.
Because your engine was developed with 5w20 oil in mind when it was constructed, all of the parts that come into contact with it must be a specified viscosity after the engine hits operational temperature, or 212.
5w20 oil will have a lower viscosity than 5w30 oil at this temperature; it will flow more easily and with less resistance. When 5w30 is used in place of 5w20, the engine will experience increased oil resistance once it reaches working temperature, which the engine is not built to manage.
If you substitute 5w30 oil for 5w20 when doing so is not advised or authorized by the owners handbook, it could violate your car’s powertrain warranty, impair engine performance, and ultimately harm your engine.

What does engine oil do?
There are several ways that engine oil keeps your car running. It lubricates engine components to allow for easy movement while reducing heat and friction. It also serves as a pump, drawing heat away from the combustion cycle, which is the process your car’s engine parts go through to keep it going, as it travels about.
You should change your oil frequently, either at a service or if you notice any of the problems listed below, as your oil will eventually degrade with continued use, become thinner, and become contaminated with dirt in your engine, which will hinder its ability to lubricate effectively and affect your car’s performance.
What oil should I use?
Call a nearby garage and ask an expert, or consult the manufacturer’s manual to find out which oil is recommended for your automobile. You must make sure to use the appropriate oil for your car because different types of oil have different qualities. Oils vary in weight and thickness (sometimes referred to as viscosity), and you need the ideal viscosity to ensure proper engine performance.
Signs you’ve used the wrong oil
The engine may seem noisier or start making a ticking noise if you applied the incorrect oil since the parts are working harder to get the engine moving. If the oil is too thick and cannot flow around your engine as easily as it should, this can also be a problem in cold weather, making it more difficult to start the automobile.
Because using the incorrect oil can create leaks, you might see a few oil stains in your garage or under your car, or you might smell burning when driving. Engine parts may not be adequately lubricated if the oil isn’t performing as it should, resulting in friction and the potential for burning the oil. This is unquestionably a red flag that needs to be addressed right away.
The fact that you feel like you need to fill up the automobile more frequently may possibly be related to the oil. Your engine will have to work harder and burn gasoline more quickly if the oil you’ve used is too heavy and thick to function properly.
What to do about it
If you put the wrong kind of oil in your engine, your car may still operate, and you may be able to drive it until your next service, but we don’t advise it. If you discover that you accidentally used the wrong product or if you experience any of the symptoms we’ve discussed, you should have your car checked out and have the oil changed to prevent long-term harm.
