The manual recommends 87 octane but it also says research 91? Anyone know what that means? Anyone experience using other grades besides 87 without any problems?
Thanks for your response, it did help a lot! When my tank gets low, i will put a gallon of a higher octane to see how it runs.I think I remember reading on the Genesis forum some time ago it was said that the Genesis engine's potential horsepower maxed out with 91 octane rating. I believe (in the Genesis at least) that 87 could be run if that specific individual engine would behave with it, but a lower horse power would result. Engine ignition timing settings, compression ratios, etc. would be a big part of whether that would be fact.
I guess that would be a general statement for most engines, but I wouldn't bet on it for the Cadenza. Sometimes HP ratings are committed to on manufacturer statements under strange DOT or place of origin regulations and guidelines.
Any opinions out there? I guess this may not be the kind of answer murrwin is after.
Thanks!3.3 is ok with 87, the 3.8 likes 93
Every three or four tanks I will fill up with the good stuff. I guess it's psychological but I feel that it helps to clean the crap out of the chambers and maybe even the injectors. Probably not so much, but it makes me feel that I did something nice for the car. The ECU no doubt compensates the engine performance to handle the added octane....i will put a gallon of a higher octane to see how it runs.
i'll prolly leave the headlights alone... i too am scared to screw something up, esp because of the articulating headlights. once i find some LED Fog replacements, i'll tackle that and hopefully mod them for DRL along with the existing LED light bar in the headlight fixture.Thanks!
Can you keep me/us updated with your modifications? especially with the Headlights and Fog Lights. I bought new DSC1 HID Lights to change them from 4300K to 6000K. I want to do it myself but scared to because I don't want to break the clip. let us know how it goes and what to do if you don't mind. Hopefully everything will go okay if you are changing them yourself.
John, it's not good to experiment with gas which is not recommended as it could damage your engine more than help....Every three or four tanks I will fill up with the good stuff.
I also dump in a bottle of fuel additive once in a while...also probably more good for the psyche than the car.

You can read about octane rating on wiki:The manual recommends 87 octane but it also says research 91? Anyone know what that means? Anyone experience using other grades besides 87 without any problems?
John,Andrei, I just wanted to give you some [email protected] for a change. I'm always too nice to you. lol
John
BINGO! I agree with that, Andrei.However it also said that engine could use 87 or higher...
So we need clarification from KIA engineers what is safe to use except 87
Oh okay, yeah I'm on the same boat. I already bought 6000K HID replacement bulbs. The car takes DS1 Bulbs, they are really easy to replace usually but in this case the car has one chrome bracket around the bulb which is making me scared to try and remove. Other wise it is a simple swap. The bulbs only cost $100. The fog lights take H8 which are standard and should be an easy swap hopefully, i'm going to get the 120 SMP LED Bulbs for the fog lights. After that I will get 2357 Front Turn Signal LED Switchbacks. The whole front of the car will be at 6000K!i'll prolly leave the headlights alone... i too am scared to screw something up, esp because of the articulating headlights. once i find some LED Fog replacements, i'll tackle that and hopefully mod them for DRL along with the existing LED light bar in the headlight fixture.
