Of course it is . But in your manual it says what oil to use , how many miles between oil changes or how much time. I would expect it to read 6000 miles or 6 months or something like that. Also Kia has one of the better drive line warranties so why would you not do what the factory recommends. ---

Your Kia has a 10 year 100000 mile powertrain warranty. I think it call for oil changes twice a year or at specific mileages which ever comes first. If you want to use the Mobile 1 annual protection so you can change your oil only once a year, you will absolutely void your warranty. Your car doesn’t even require synthetic oil, you can use it but you can’t extend you drain intervals under the warranty. ---

Once again we are comparing maximizing oil life vs. maximizing engine life. Follow the owner’s manual and have your engine last a happy and safe life. If you want to use synthetic, make sure it is the right weight (viscisty) for your car and do not extend the oil change interval. ---

Kia’s 10 year 100,000 mile powertrain warranty only applies to the original owner. If OP purchased the Optima new all advice given is valid. ---

Yes, but the second owner get a 5 year 60,000 mile powertrain warranty. ---

Depends on how long you intend to keep the car. Mobil 1 will absolutely enhance engine life, so if you plan to keep this beyond the warranty periods, definitely use it. I used it exclusively in my last 3 cars which all went over 150k (one was at 202K and engine was still great when I traded it). However, warnings about change intervals to keep up a warranty are very good points to remember. ---

This car has the Theta II direct injection engine which is prone to premature bearing failure. I would do low mile oil changes and keep the receipts. Extended oil change is not for this engine IMO. I have two cars with the same engine and even after 3K miles I can smell the gas dilution in the oil. ---

at walmart reg mobil 1 is $7/qt and super mobil is $8 and 1yr is $10/qt. so its hard to say if yearly oil changes saves any money on oil costs. i figure 5qt jugs is less per qt. maybe materials but not your labor. and the point of oil cost vs engine cost is a good one. 10qt is cheaper than the royal purple stuff
