High fuel consumption ECO

[Ah GetFd]

Why would I want to avoid a dickhead like you, you come on here & run members down with condescending comment, you talk like you know everything, most people can Google facts just like you do.

You seem to have a big chip on your shoulder, your not on a Commodore forum now so there is no need to be a smartarse here.

dickhead.....smartarse....

seems to me that you are using the derogatory words.......

all I did was correct you on your misinformation...........

if you can google the facts then do that

it sounds to me that you have the huge chip on your shoulder

¡Ay, caramba! This diatribe tells me you have no clue what you are talking about.

Premium doesn't resist detonation by being less volatile or burning slower. That is just a simpleton trying to rationalize with simple concepts that he can understand but have no basis in reality.

Even the most basic of concepts of octane ratings you get absolutely wrong. For you folks down under, Kia doesn't recommend 91, since your octane ratings at the pump are denoted in RON (Research Octane Number), same as in Europe. Here's the exact verbiage:

"For the optimal vehicle performance, we recommend you to use unleaded petrol with an octane rating of RON (Research Octane Number) 95 / AKI (Anti Knock Index) 91 or higher. You may use unleaded petrol with an octane rating of RON 91~94 / AKI 87~90 but it may result in slight performance reduction of the vehicle. (Do not use methanol blended fuels.)"

Here in USA and Canada, our pump numbers are in AKI (Anti Knock Index), which is (RON+MON)/2.

FWIW, 91 RON is equivalent to AKI 87. 95 RON is equivalent to AKI 91. So for Australia, Kia's recommendation is for premium 95 RON gasoline, for optimum performance.

Now then, is premium gasoline absolutely necessary all the time? Of course not. Octane requirement for any engine is not a constant number. It varies depending on how the car is driven and under what (vehicular & ambient) conditions. WOT uphill in 105F Summer heat fully loaded with passengers and cargo, towing a heavy trailer near sea level has an octane requirement very different than, say, flat hwy cruising solo in Winter at steady 55mph in mile-high Denver. Kia doesn't know exactly how every driver of their cars will do, so their recommendation covers the worse case scenario. It is contingent upon the driver/owner to pump what is expected of the car for the next tank full.

I personally have no problem pumping regular grade, if I'm just commuting and taking it easy in cool weather. However, for track day or AutoX, especially in hot and humid Texas Summers, you bet I'll make sure the tank has nothing but the highest grade pump gas. Maybe with a few gallons of E85 added for good measure.

But, you - like all of us - are free to pump whatever you want into your own cars.

Just don't talk out of your behind on subject matter you barely have a rudimentary understanding.

"Premium doesn't resist detonation by being less volatile or burning slower."

Yes it does

You could research that and you will see I am right

Less volatile means detonation is better controlled

Burning slower because it's volatility is less and more controlled means more of the energy is extracted from the fuel

But you know that.

Googling acronyms then printing them doesn't prove more.

A higher AKI fuel resist detonation by being able to withstand higher Peak Cylinder Pressure (PCP) and charge temperature without ignition. This means the fuel has already flashed into gaseous state and formed into a fuel air mixture ready to ignite but has not - even in the presence of very high intra-combustion-chamber pressure and temperature that would otherwise auto-ignited a lesser AKI fuel. This auto ignition, or preignition - without spark plug firing - is the very definition of detonation/pinging/knocking/preignition (all part of the same phenomenon but in varying degrees of severity).

The very fact that this high-AKI fuel-air mixture has not self-ignited means it has not started burning yet. No fast burn, no slow burn, NO BURN... period. That means your statement about "burning slower" is just full of self-defecating bovine excrement.

A higher-AKI fuel's ability to achieve more power comes from the very fact that it is able to withstand higher PCP and only ignite when the spark plug fires. This higher PCP produces higher thermodynamic efficiency by starting the compression stroke with a higher initial pressure. This higher pressure forcing the piston downward ultimately produces more work done per combustion cycle. This is why higher octane fuel can produce more power.

Some of us don't need to google this, because some of us went to school and actually studied this stuff.

You OTOH can't even get your combustion event sequences straight, much less being able to know the difference between enthalpy, entropy, and a hole on your behind.

The bottom line is

Premium fuel does not provide any benefit to a Stinger.

Premium fuel is designed to protect a high performance (Ferrari for example) engine from pre detonation which then protects all the components.

Nothing more.

It does not elicit more "power" for a Stinger or the majority of cars out there.

It's a myth

So, we take your word that KIA is talking crap when they recommend premium gas. In order to use regular gas the ECU has to adjust/compensate. I say that not requiring that from the engine in order to use regular gas is a benefit over time. That's my bottom line. I've never used regular gas in my high performance engine. A Ferrari is just more high performance, so is a Vet or a Viper.

I'm searching for the document that states although the gas cap has a 91 sticker inside, that is in reference to 91 Korean or i believe your guys equivelant rating there which is 95 over here?

Found it

 

[Ah GetFd]

No sticker on a fuel lid in Australia will refer to anything other than meets the standards here.

And seeing you called me a dickhead and a smartarse when I pointed out your stupidity in relation to servicing........

Let me call you a dickhead. But I will change it to dumb arse for yourself

Kia does not recommend Premium here. Standard Unleaded.

You are wasting your money.

A Stinger is not designed around Premium fuel but look......you stick you catch cans on and your premium fuel in and feel like you have improved your Stinger.

NO-ONE in the world uses catch cans on a petrol car outside of the idiots in the US.

It is designed for diesel engines. Nothing more.

Idiots

How is that clown ^^^ still allowed to post on this forum?

Just WOW.

 

[Ah GetFd]

I guess once they find something that is not true they will ban it. Until then I am here to teach "newish" members a thing or two.........

wow.....
