Hey, Reading the owners manual, KIA recommends adding a fuel additive IF not using Top Tier Gas. All gas in the US is top tier and I usually only pump from Shell. I wanted to know if there's a difference / advantage of using 87 vs 93 octane rating gas since all grades qualify as "top tier"...

Why you might ask?? Umm...I watched the Netflix movie "Pump" and decided it would be fun? Any claim on improved performance would be foolish, but in my head, it feels nicer driving so far. How about fuel economy? I'm going to tell you that it has been no different so far in mixed...

Does anyone else attend these events in Atlanta? I took the optima up there this weekend hoping to find another k5 in the parking lot... but left thinking that perhaps i should take the Lotus to next months event since there were actually a few present. :) At any rate, if anyone wants to join...

Taken from a BTR tune thread here: http://www.optimaforums.com/forum/130-optima-performance/65362-btr-blood-type-racing-tune-v2-0-3-update-optima-sonata-2-0t-gdi.html I certainly recall the same thing when I bought mine. I remember even being told to run the 91 tune instead of 93 when the...

I found a place that carries 100 and after calculating it, I believe the mix would be 14 gallons of 91 and 4 gallons of 100 to get 93. I'd prefer to just buy 93, but doing this occasionally wouldn't be horrible, it's just a bit pricey. The place I found is a Flyer's on the corner of Watt and...

Has anyone tried using premium gas to see if you get more mpg?

Ok so we've had the car approx 2 months and since its the wife's car she has been putting in 87 octane like she did in her Subaru. I have been watching her average MPG and its been 24.5-24.8 (freeway and in traffic). Last week I filled up the car and put in 89 octane just to run the better...

Hya peeps, I'm coming up on my purchase (4months) but as i always do, i do as much research as possible before making my purchase... There is so much awesome info on here so i'm sure i can get an answer. so my question is..... Is it ok to fill the tank with 93 instead of 87... will the car...

I have only had my SX for 46..well 47 days now and I seem to get about 19-22 in the city. I have not taken it on a long trip yet. That will be next weekend. I do know that I filled up on 9/8/11 and it read 431 miles til empty. Now it reads 272 miles until empty. I have only driven 107 miles...

I was pretty surprised when I read that the Optima 2.0 turbo can run off regular 87 octane fuel. Is there any performance advantages (with the stock ECU) to running 93 octane? I know some cars have octane sensors that will de-tune the car to make sure there is no pre-detonation. I have...

The title mostly says it all. I know the engine is designed to work on 87, but, I was curious if the ECU would be able to take advantage of more octane? A few more horses or slightly better gas mileage perhaps? My friend has a 2011 Camaro 2SS that can run on 87, but loses 40hp, so it got me...
