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.

Should I fill up my Kia Optima with synthetic oil?
Synthetic versus conventional oil Technically, using standard, or conventional, oil will not affect how well your Kia performs. This oil is extremely unfiltered and is in its most basic form. This implies that it won’t perform as effectively as synthetic oil, though.
Can I replace the 5w20 in my Kia with 5w30?
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.
Using the proper oil keeps your engine operating at its best.

Oil Change Schedule for Kia Vehicles
The owner’s manual for each Kia car will tell you how frequently you should change the oil. There are, however, certain fundamental rules that you may use on any Kia vehicle and still be safe! Generally speaking, your Kia should have its oil changed every 7,500 to 10,000 miles. For the majority of drivers, this mileage restriction equates to every six months.

Importance of Oil Changes for Kia Vehicles
Oil changes are essential to keeping the engine in your Kia car maintained, as we said at the beginning of this article. This is true because engine oil lubricates your engine and lessens the friction that the moving elements of your engine produce when it is operating. Oil that hasn’t been changed in a while may grow thick and ineffective in reducing friction. Engine wear becomes more harsher and may possibly lead to significant mechanical problems as friction rises.

Can I substitute 0W 20 for 5w 20?
The 20 in 0W motor oils (also known as 0W-20) stands for the viscosity measurement value, making them appropriate for usage in 5W applications. The most important factor to match when choosing a motor oil is that value. The pumpability at cold temperatures is shown by the 0W or 5W. Consequently, a 0W would flow more freely than a 5W and might be a suitable replacement. As a result, SAE 0W-20 can be used in place of SAE 5W-20 application.
**Provides improved fuel economy and faster flow while yet offering the same level of protection as 5W.
What makes 0W-20 and 5W-20 different from one another?
The Society of Automotive Engineers assigned these oils a viscosity grade, which is a numerical value (SAE). The numbers before and after the W denote the oil weight in cold and warm temperature settings, respectively, while the W stands for “Winter.”
These motor oils both have a comparable, wide working temperature range, and are typically used as winter viscosity oils.
On closer investigation, you will see a few slight variations:
A. Cold Viscosity
The ability of an oil to flow is measured by its viscosity. It also describes the thickness of the oil at various temperature levels.
When operating in freezing temperatures, 0W-20 motor oil performs like an SAE 0W weight oil. While 5W-20 oil functions as an SAE 5W weight oil.
The better the motor oil performs at low temperatures, according to SAE nomenclature, the lower the number before the ‘W’ is. Since 0W20 is much thinner than 5W-20, it is more stable at low temperatures and flows easily through the essential engine components.
A more suitable oil for a typical operating temperature range of -22F to 68F is 5W-20, which has a viscosity that is relatively thicker.
B. Hot Viscosity
At higher temperatures, both oils behave as SAE 20 weight oils. They offer reasonable fuel consumption, improving fuel efficiency while lubricating all of your important engine components.
Both of these grades perform well up to 68 F in terms of their operational temperature range. Under circumstances of high oil pressure and higher temperatures, they are resistant to issues like oil burning and excessive oil consumption.
C. Performance
The thinner oil grades 0W-20 and 5W-20 both work best in cold winter climes.
The 0W-20 oil grade performs better with cold starts due to its reduced viscosity. Additionally, it guards against issues including varnish buildup, engine wear, sludge formation, and low oil pressure. With 0W-20, you may anticipate faster oil circulation and a smoother flow.
Therefore, 0W-20 oil grade would be the best choice for you if you plan to travel frequently in regions with below-freezing temperatures and infrequently in regions with higher temperatures.
However, 5W-20 performs a little bit better in seasonal climates due to its higher viscosity. Because of its somewhat greater thickness, it resists oil thinning at higher temperatures better.
There are some vehicles that can use both 0W-20 and 5W-20 oil. However, consult with your mechanic regarding the suggested oil for your vehicle before switching to a different viscosity grade.
D. Fuel Economy
The mileage and fuel efficiency of both 0W-20 and 5W-20 oil are essentially the same.
Due to its thinner oil flow and low viscosity, 0W-20 oil may provide you somewhat improved fuel efficiency and less carbon emissions.
The type of motor oil you useconventional, synthetic blend, or totally syntheticalso makes a difference. The 0W-20 and 5W-20 motor oils are fully synthetic and will provide the best possible fuel economy.
E. Pricing
Typically, 0W-20 oil costs a little bit more than 5W-20 oil. This is due to the fact that it is more stable than the latter due to being a full or semi synthetic oil.
Your engine oil’s cost varies from provider to seller as well. To choose the most economical alternative for your car, be sure to consult your mechanic!
What are some things you need to understand about these multigrade oils keeping these in mind?
Which is better for heavy mileage, 5W-20 or 5W-30?
As you have probably already deduced, 5W20 performs better in cooler climates. 5W30 will be the best bet if you need engine oil for summertime performance. Only your own mechanic or the car’s manufacturer should advocate switching to this sort of oil, though.
By using an oil that your engine isn’t made for, you run the danger of damaging it. Keep in mind that 5W20 motor oil will flow through your engine more readily than 5W30.
If nothing else is specified, keep to 5W20 during winter. Use 5W30 in the summer if doing so won’t cause any problems for you.
