I tried to put this in the "Dealer Experience" section but it required a prefix and none of the prefixes available were appropriate, so I'll hide it here.

Dealers are supposed to send technicians to training on the Stinger. Usually these are a couple of the top technicians who have been around a while and are reliable. The problem arises when service scheduling puts an "un-Stinger-trained" technician on a job where some level of training is needed. Otherwise good mechanics have done some stupid things like switching the 19" wheels front to back and damaging the calipers, cracking the plastic cap on the cartridge oil filter with improper torque -- simple stuff that only requires some knowledge they don't have.

When I was a service manager, it was a constant juggling act to try and even out the work so everyone was busy doing what they were trained to do. We had journeymen on the lube rack (yeah, I know you don't lube anything any longer) changing oil, rotating tires and doing the cheap profitable stuff, and the good techs were fighting time-consuming and pay-eating diagnostic problems and didn't have time for the gravy jobs like brakes and tuneups. So it's easy for your Stinger to end up in the hands of an un-Stinger-trained mechanic.

What I try to do is find a technician who is Stinger-trained, visit with him (or her!) over lunch maybe some time (you buy the lunch) and then, if you feel comfortable with that tech, request that technician when you schedule your trip to the dealer. Works both ways. One -- you get the trained technician working on your ride. Two -- he gets some easy maintenance work by request. Three -- he knows that you know who is working on your car and he is less likely to try and sell you work that doesn't really need to be done.
 
Nice to get some insider advice. It's unlikely I will ever get to know who may be the Stinger expert at my dealer, they are a pretty large service center, but I feel the Kia's great warranty will mitigate any harm done by the untrained. Not as good as knowing the work is being done right the first time, but it'll have to do for me. Plus it's a lease, so no matter how bad any work is done, I won't have to live with it beyond three years.
 
So, curious, the dealership and the manual says to use 87 octane (research octane number 91) or higher. Kia sites, however, recommend premium unleaded. Does everyone just use premium or do they use 87?

Down here on FB you just have to ask that very question it gets quite heated everyone has an opinion and they're all willing to tell you and why they are RIGHT.

It baffles me that the owners manual and dealership (salesman and service department) says 87, but then their site says premium. Why the conflicting info?

I think the 87 octane is left over from the original publication of the Owner's Manual. Mine says 87 minimum. Later owners have posted screen shots of their manual which says 91 minimum (I think it was 91 if I remember.) Anyway, I use the highest octane I can find which varies in different parts of the country. I can get 93 at Sunoco but most are 91. And if you are in mountain states in the U.S. it's lower than that due to altitude adjustments.

I would use only premium 91 or better. Also note that they recommend only top tier gasoline which has met additive standards to help keep valves and injectors cleaner. (See web site toptiergas.com for a list. Most major stations are included but not the truck stops and local chains.)

OK, well, I've been using 87 but from now on its 91 or higher. Hopefully I haven't done too much damage with the lower stuff. Thanks

Can you link to where their site says premium?

Some of our "premium" gas contains 10% ethanol with 91-92 octane ratings. Any problems with running 10% ethanol "premium" in the 3.3 TT GT2? And putting the ethanol aside, any benefit to running 93 v. 91 octane premium?

There are a ton of threads on this topic
 
Ethanol actually raises the octane rating of fuel a little which is one of several reasons gas companies use it. Other reasons include the big tax rebates and incentives to farmers growing corn making if feasible for fuel use. It is cleaner burning than gasoline which is a complex mix of hydrocarbons containing random sulfur links in the carbon chains. But ethanol has a lower energy capacity than gasoline so it will cost you a little fuel mileage. It won't hurt anything in modern fuel systems which have been engineered to handle the solvent problems. 10% ethanol fuel won't hurt anything and you often can't avoid it. As I posted above, try to always use top tier rated fuel for the additives because valve deposits are a potential problem with GDI fuel systems.

You haven't damaged anything
So I have an update.

Edmund's makes lists of cars that are premium unleaded recommended and premium unleaded required. 2018 Stingers, all models, are listed as premium unleaded recommended, not required. Same for 2018 Genesis G80 and G90.

For 2019, neither the Stingers, nor G90, G80 or G70 are on either list.

I don't think fuel additives do anything for the valves on a GDI engine, as the fuel is injected directly into the combustion chamber. I plan to inject some Seafoam on mine periodically, or a similar product, into the upstream intake.
 
I only use premium in my cars, here in OZ it’s 98 octane (my preference is Shell V-Power)
Also see shot below from my 10,000kms Dealer Logbook Service & you will note on the list that they replaced my genuine fuel additive (injector cleaner).
