Gas requirements

I looked on the Hyundai site, but I am not clear.

What grade of gas does the 2.0 T use?

What grade does the 3.8 use?

You may use any grade you like. However, many of us report slighter better performance and mileage with higher octane ratings. Hyundai provides two horsepower ratings based on regular and premium fuel.

I find mid-grade (89) works best for me. It bumps-up my mileage enough to more than cover the higher cost. Others swear by premium. There are a lot of threads on this and many take on an almost religious slant. Enjoy.

That is why I was confused I thought there were 2 grades listed, I never saw that before for one engine/car.

So if you use regular you will not compromise the engine then or pinging?

I will be using regular 87 fuel, at least until gas prices go down. I'm coming from a car that required 91+ octane fuel so it's going to be nice not having to pay for premium.

Hyundai boasts of their knock sensors allowing use of regular or premium. I would like some MPG comparison between the two fuels to see if the price difference is made up by the higher MPG you are most likely going to get from premium fuel. I doubt it, but it would be a cool project.

I didn't miss it, as stated, I never saw a manufacturer list 2 grades of gas before for the same model so I was double checking from owners that have the car to see what they thought about the grades that they are using.

Per the 2013 genesis Coupe Owners manual, a Rating of 87 and above is required. Personally I user 89 as it is not drastically more expensive than the 87 and will keep the fuel system cleaner over time then 87.

Fair enough regarding the cleanliness I bought the kool-aid. As to bumping a 3 year old thread, I just noticed the thread earlier and had just read this in the manual the other day. I was interested in what others were using so I posted what I found in the manual.

To me, this topic has become like asking why we have to brush our teeth, or why we use a product like Crest Complete instead of baking soda

The extra cost of premium is usually balanced by the better mileage, but the better throttle response, even better shifting, and general performance improvements, should be obvious. My 2012 owner's manual even recommends "Top Tier" Premium, although it notes the car will function on 87 and ethanol up to E10. However, I've found that my car starts to sputter and get horrible mileage and performance (thus burning more gas) even on something normal like BP Ultimate E10, not to mention the cheapo brands - save those for the minivans of the world.

Premium 91-94 Top Tier fuels have their brand's best chemical additives, which is where the superior cleaning, ethanol counteraction, better octane and general performance aspects come from, and you generally need the premium to get the full package. So, I use Premium/93, always. I use Shell V-Power almost exclusively (depending on trip/region availability), in which cases I will only run another Best of the Top Tier fuels, like Chevron Techron, Sunoco Premium, Petro Canada Premium, etc. I consider Exxon, Mobil, BP and other common major brands to be second tier.

My car sure is happy

As Hyundai states, there is a performance difference between regular and premium but I have never noticed any difference in MPG and I can measure that on the road.

The good old days when I posted this. Actually I was questioned about asking at the time when it was on Hyundai's site. Well at the time I did not have the car yet and was looking at a 2012 and a 2013. The 2012 did not mention both grades of gas only the 2013 site had it.

As for the poster said 89 better additives, not really true, just the brand of gas matters like the top tier stations like Shell and some others which I forgot have more additives.

I am all about that V-power shell. I will actually drive out of the way if I have to. Shell V-power combined with SFR stage 1 tune gets me 26 city and 32 hwy (65-75 mph) .
