Why does a hyundai take supreme?

Some people prefer it because it runs smoother. It’s only like $3 more when filling up. California has weird fuel formulations so it probably has something to do with it.

It doesn't "run smoother." You're pissing money away if you're putting higher grade fuel in your car than what it's tuned for

This.

Higher octane levels doesn't mean shit if your engine isn't designed to handle it.

Regular fuel is fine for a 4 cylinder vehicle unless stated otherwise in the fuel cover.

My truck specifically asks for mid-grade or above. So I never put regular in it.

In most cases, using a higher-octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner.

You are correct, to say that nothing works in the power performance, but if it avoids wear on the engine because the higher octane fuel contains better additives than the regular one, and it is also a matter of taste and the money that is want to spend on fuel

I'm surprised its only a 30 cent different between 87 and 91. Here in Oklahoma its over 60 cents between them.

WTF Hyundai takes 17.6 gallons to top off? And same question with 91 octane. Not judging just asking. I have a 2016 Santa Fe 2.0T and I pump 87 in that bitch and it zooms like a K-Pop dancer pounding Soju... 20mpg if I'm lucky 😬

It doesn't run smoother. I am not sure where the hell people came up with this myth, but it is not the truth. Higher grade gas is for high combustion engines.

Recommended for engines with a turbo chargers, prevents pre-detonation due to higher pressures in the cylinder around TDC during compression stroke. But you don't need 91. Then again, this is the "Home of the Free", and i have no idea what Hyundai he has.

I run non-ethonal 91 in my RAV4 Hybrid and notice a jump in MPG.

Aren’t many of the new engines in cars running turbos and direct injection? That shit broke all the time on my German import, so I’m shocked to see that crap on cars that should be cheap and reliable. I would be hesitant to put 87 in a blown 2 liter 4 banger putting out 200 horses, but maybe I’m old and out of touch.

I have a Santa Fe 2.0T and calls for 87. I just get top teir 87. 265HP and she runs baby.

I think you mean 235HP, but close enough. Torque is more important for pickup than HP

Nope, 265HP. They nerfed the later models, I assume for better gas mileage because I get 20mpg, if I'm lucky driving around. Highway is a bit better. The MPG meter is not accurate.

I buy Supreme for my 5.0 Ford F150. I made the commitment when I bought it and still while I'm broke buy Premium. It's a 2014 that I bought new, paid for and still runs like a good truck should. Of course, I'm in South Louisiana and it costs less and I'm driving less now but I believe it burns cleaner and doesn't hurt as much as it may in the near future.
