The Fuel Grade Poll

**Marc Collins** · 03-06-2018, 12:02 PM

I have no concern that Kia would say use the minimum available in any particular country. The simple question, that still no one seems to be able to answer, is what octane level is required to get the advertised HP and torque numbers?

So, out of interest, in Germany where you cannot use anything below what is classed "premium" elsewhere, are the HP and torque numbers the same as North America, or higher? If they are the same, we still don't know if higher octane fuel is used to calculate. If they are higher, then it is a clue that more power will be gained by using premium. If they are the same it can also mean that the engine computer adjusts itself to produce the advertised power whatever you put in it. The higher octane will be cleaner for the environment, though, and maybe better for the engine in the long term.

These are the number for Germany:
370 HP @ 6000 U/min
510 Nm @ 1300 - 4500 U/min
0-100 km/h in 4,9 s

I think we need to put the Stinger on the dyno to check the differences.

Same as North America....which may or may not be with similar higher octane fuel as Germany. It would take 2 seconds for Kia to clarify, but like all manufacturers, they prefer to leave these things shrouded in mystery. Wonder why?.........

These are the number from the Kia USA homepage:

365 Hp
376 lb-ft

Maybe these 5 HP are the difference?

510 Nm is exactly 376 ft-lbs. The HP is calculated slightly differently in Europe than in USA/Canada (check every other car and you'll see the same slight difference), so these are the same numbers.

I'm new here. Just got my GT2 less than a week ago. My manual says 95RON/91 anti knock rating which equates to 93 octane in the US. So why would anyone be using anything but premium in the US?? The part of my manual that says this has a sticker over something that used to be there so I can't read what used to be there. Did they change the original recommendation or something?
