is Mobil 1 Annual Protection safe for cars?
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.
