Which engine oil should I use for my 2014 Kia Optima SX Turbo

It is very important to use the proper oil with the proper weight in your 2014 Kia Optima SX Turbo because the tolerances on these modern Kia engines are very exact.  If you use a heavier oil than Kia recommends, you may expand the area between lubricated parts.

What does this mean?  It means that the heavier oil may cause oil loss and smoking.  Kia recommends you use 5w-20 weight motor oil in your 2014 Kia Optima SX.  The 5w-20 weight oil is lighter and when it leaks into the cylinder (which is normal), it is burned off and does not smoke.  The heavier oil is not as easily burned off.



If you have an emergency and you don't have 5w-20 oil, you can add a different oil weight temporarily.   Use no more than you need and then change the oil and filter as soon as you can and replace oil with 5w-20 oil.
