Hi all,

Curious as to what gas everyone is using in their 1.6T (non GT). I know the manual says 87 or higher, but what are the majority of people using?

Im in CA, so I already get ****ty gas to begin with

Comment on the brand and octane your using in your car

I'm running "top tier" 87.. I live in ny.. premium is too rich for my blood.

I'm so used to putting in 89 in my tank... lol It probably wouldn't hurt to use 87 so long as the gas has cleaning agents to prevent carbon build up. It's definitely not fool proof but anything to help keep the engine running smooth for longer.

I’ve tried 93 octane “premium” several times and I’ve noticed absolutely zero difference in performance or mpg. I use only regular 87 octane now. However I have noticed a big difference in performance between name brand and off brand 87 octane. My car runs great on 87 octane Sunoco gas but runs terrible on off brand Wawa gas (it’s a NJ and PA brand).

exactly the info I needed. 87 it is. I’m gonna give a few top tier brands a try and see what the car likes best. Thanks.

Yeah, apparently all grades of gas have the same energy potential. The octane just means how consistent the burn is. The higher the octane, the less likely it is to cause uncontrolled mini explosions in the chamber, and therefore reduces engine knock.

Most engines today that take 87 octane have sensors to deal with the engine knock already so we're good to use 87 on the 1.6T engines.

One thing that higher octanes can do is help keep the fuel injectors clean, though, so putting in higher octane once in a while wouldn't hurt.

I use 87 BP or Sam's club

 

[StarMerc698]

87 is the go to, but she has had a tank of 93. Will say the car runs better on 93, but I'd like to not take a second mortgage on my house to fuel up with it.

If you are concerned with fuel quality and have easy (and cheap) access to a fuel additive, go for it. I'm the Manager for an Auto Parts store, so I can secure Seafoam super cheap and run it when I feel the car needs it.

I use 87, and have driven almost 11500 miles, no problems. I'm going to start putting in a fuel additive every oil change though, as well as filling up one or twice in between with 93 to try to clean the injectors out. Also I think seafoam should probably be done every 10k miles too. Which I'm overdue lol maybe I'll do the seamfoam today and record it lol

I’ve seen several videos and read enough about SeaFoam to conclude that it’s really not that effective. It was originally invented for marine 2-stroke engines and does do a decent job on 2-stroke engines. However the carbon buildup in modern GDI engines is different. The only fuel system cleaners that actually do anything for a GDI engine is any cleaner that has the chemical PEA in it. I use Gumout Multi-System Tuneup. It’s one of the few that still contains PEA. There are a few others but most don’t have it.

Well looks like i'll buy it next time I do an oil change. I just dumped 2 bottles of seafoam in each of my K5s yesterday. I wish I saw this before I spent $25.00 on seafoam lol

I use premium Gas in my K5 EX

 

[DBKC]

I use only NON Ethanol fuel in everything I own that uses gas. 91 octane gets me great mileage and performance. I got 37 mpg on my last road trip running the a/c and rolling at 80 mph.

I don't even think non ethanol fuel is an option in New York State. I looked it up ... apparently Stewarts 91 octane gas is ethanol free. There is one around the corner, I might need to give it a try assuming I don't have to sell my 1st born to pay for it.

here in cali we have no option of non-ethanol either. On top of that, we get special CAN gas, specific to only california, nevada, and arizona due to emission regulations.

Dang, the 91 premium is $3.87 a gallon, about $.80 more than I paid yesterday at speedway for regular 87. I don't know if that is worth it for 1-2 MPG extra.

no not at all. the price jump to premium used to be only $0.20 a gallon, now its at least $0.60 around my area. Im stick with 87 and fill up with premium occasionally to help clear out any build up.

Just as a note I would strongly suggest signing up for Gas Buddy and their Pay With Gas Buddy add on. You by default get a couple cents off per gallon. They also work with Fuel Providers to give additional discounts. For example I got an additional 10c off/gallon just last week from Speedway for reporting a price and pressing a button. I have seen BP with 5c off and occasionally 30c off/gallon at some lower volume stations. (Note this is in ADDITION to membership discounts)

(If you plan on signing up feel free to message me I can provide my referral code but am not going to post it here. Just because I think that's tacky)

Oh cool thanks I'll look into it. If they work with fuel providers in my area then that could definitely be beneficial. Will message you if they do!

Looks like in the KIA app it recommends 90 or higher!
