Regular Unleaded in Twin Turbos

[IG88]

Do you do any "damage" to the 3.3T V6 Twin Turbo in GT Stingers by using only regular grade unleaded or is the effect mearly a reduction in power output?

If only there was some guide provided by Kia on this subject....


since it doesn’t say “you will blow up your engine”...

guess that means you can put whatever you want in it.

Thanks. I'm kind of a penny pincher so I'll go mid-grade. I don't think that should damage the engine over time at least.

Not a good move for the long term. Make sure you disclose to the future buyer that you put gas in for the life of the car.

Put the fuel in the car that it calls for you cheap bastard.

lower the number, the easier it ignites under pressure. in a turbo car, pressure is boosted so fuel can pop under pressure alone before the spark plug tells it to causing pre ignition aka knock. this is bad, similar to double bouncing on a trampoline wrong and it hurts your knees. so in short, sure you can run lower octane. i wouldnt go smashing the gas and loading the car (lugging is where youll cry from the bills). i only recommend lower octane if you go to a pump in the middle of nowhere as high octane is likely old and no bueno

Just skip that $5 coffee once or twice a week and fill it up with premium. Be cheap somewhere else in your life. Your dating the prom queen, boxed wine just won’t do!

Mid-grade is the biggest ripoff in fuel anyway. Might as well get regular at that point.

The car adjusts for different gas as far as I know, you can use regular but it will adjust the timing so you're probably losing some horsepower. Spend the extra 5 and put premium in, not somewhere to penny pinch IMO.

What @Spaceme17 said (sans the rude content ). If you bought a Stinger, why would you not want instant TOP performance on demand? The option, you see. I don't get this repeated debate on chincing out on gas. It's a performance car, and Kia recommends a minimum octane. The engine compensates for cruder octane. So why make it work harder (unnecessary complexity) when it doesn't have to?

I travel through a lot of back hwy to work. I carry two bottles of octane boost just to be safe. Put as little possible. Till i get to better gas. 93 is my preferred no upgrades yet but at least i wont see additional increase in fule cost when i do. So i tell the wife anyway.

Hmmm interesting how you read rude content and I read someone being brutally honest.

The other discussion about this just got so heated lol. I never knew people were so passionate about fuel.

Gas fires burn hottest, so we're told.

I put shell 91 in my 2012 NA 2.4L Honda swagon wagon. I think that makes my position clear on what fuel I put in the stinger. (Also mine came tuned for 93 but can't get that here in Cali so yeah...)

Fun fact in Canada:
The 2018 Kia Stinger Owners Manual says to use 87 or greater
The 2019 Kia Stinger Owners Manual says to use 91 or greater

So even KIA doesn't really know the answer lol.

If your engine ever did get hurt by using 87 and you have a 2018 Stinger you can for sure fight them on it in Canada .

But again, totally up to you what type of fuel you put in the car.

So canada 87 is 91 RON? I know that canada gas is inferior to some US gas.

Here's a video I remembered watching a long time ago. I found it again... Not that it leans towards anyone's argument but an interesting experiment none the less
