Gas Requirements

[TheDarkness]

Picking up my S4 this week, wanted to know what the book calls for for Octane?

What about if it is chipped?

Can you get away with 89 if your not looking for top boosting?

Thanks

[torment]

just buy premium....its not much more dude

[drewwynn]

like 4 bucks a tank more, its nothing. It would be a lot easier to save 4 dollars somewhere else in the duration it takes you to burn a full tank opposed to risking your car's well being.

[volks88]

Can you get away with 89 if your not looking for top boosting?

then why buy an S4

[GQ//S4]

Only premium, never under 91 octane, don't bitch about 10 cents a gallon more, going cheap will make us laugh at you endlessly for blowing up your engine.

Wtf is an s4 without boost?

[ThirdStrike]

i love how people try to "get away with" buying 89/87 just to save 5 bucks. if i had to pay 5 bucks more/tank to get 93 id be more than happy to pay for it.

Yup, never below 91. When you get ready to chip, there are also octane specific programs you can run.

[Chknkatsu]

if you can't afford the higher oct, doesn't sound like you should be driving a S4

[So_NAudi]

or there is 109 for $5.25 a gallon out in hick-a$s middle of nowhere Wisconsin... : )

hell yeah!

[1997gtx]

The book calls for 91.

Any chip calls for at least 93.

I call on you to not be a moron.

chip tunes/flashes also have 91 programs
we westcoast folks dont have 93

[1997gtx]

^ ZOMG! A 91 Chip?

You people waste your time with that

I think W/M should be a given on any CA car

91/93 ONLY.

I explained this to my GF the other day because she too wonders why I don't just put the cheap sh*t in my car.

Take a glass of water. Would you drink water that was brown? If you answered yes, than imagine continuously drinking that brown water, over time, its bad for your body because of the crap in that water. Same concept with gas, if your car calls for 91/93, why would you put crap 87/89 gas into it?

you say 91 octane!! seriously in Ca I have only seen 92 once at the pumps..thats IT. never seen 93. so ya.

oh and I found this a couple weeks ago, you should all check it out...

P.S I have never put less than 91. My mom never got why I did it when she had her big SUV. She recently got a Mini S, and she only puts the good stuff. I think it just comes with having the car =).

Not really the right idea. It has nothing to with 91 being "crap" or a different colot. It has to do it with its flashpoint being lower then 93. You could run 91 all day long if you wanted to without getting into boost, and your car wouldnt see a difference. Start getting into boost, and your timing will go off the charts and you will risk detonation.

[RolledMySTi]

then why buy an S4

+1 If you don't want to boost buy an A4 2.8 and save yourself a lot of money.

wisconsin unite.. e85 is like 2.99 at our local kwik trip i believe. and out at the airport where i used to work, down the road at a BP they sell race gas for about 5.20 i believe. we have 2 pretty popular dirt tracks in BD, so thats where they all get it. I should go try out hte GIAC race gas program !

[SoEvoL]

91 sucks but theres always meth inj

[Chknkatsu]

A crazy third gear monster.

you made my day...I love you, no homo

[Jung]

lol i fucking love your sig. that line was the funniest shit i'd read in a long time

[TheDarkness]

Yeah, you guys are right. Just asking!! I wasn't planning on going below 91 octane anyway.

I believe this car has an APR chip, but how do if I find out what program?

[GyzmoS4]

Chknkatsu, ur sig is a bit confusing. Is your girlfriend a guy or a girl?

[1997gtx]

^ I think that's the point of it.

The guy who originally posted it meant to say "her new boyfriend," but the guy wrote "his" instead ... saying that his ex-girlfriend was a dude ... thus, making him gay.
--Adam

[GyzmoS4]

^LMAO, thanx for the explanation.

[JDM EJ1 95]

Not that funny?

[The_Jerbel]

You guys should really read your owners manual more often. You can run down to 87oct fuel safely, but you will get higher CF's, less timing, and worse gas mileage.

[JDM EJ1 95]

You guys should really do some reasearch on what exactly octane rating is and how it affects todays engine management systems. You can run down to 87oct fuel safely, but you will get higher CF's, less timing, and worse gas mileage.

fixed..


the owners manual will not give you the info needed to grasp the issue at hand..


yes you can run 87.. but why would you want to.

[mholme]

Well..you can also drive a car with your feet if you want to...Doesn't necessarily make it a good idea..

I think anyone who drives spiritedly(boosts) on a regular basis would be foolish to put 87 octane in their car, regardless of what the owners manual reads.

[JDM EJ1 95]

our ecu is very capable to properly adapt to 87.. but like i said.. and everyone has said.. why would you want to.. for 4 dollars more a tank which is practically nothing compared to our 70 odllar fill ups... its def worht it to stretch that 4 dollars and cut down on cigarettes for hte week.. lol

[The_Jerbel]

fixed..

yes you can run 87.. but why would you want to.

It's true that the great majority of people are grossly under-educated about octane ratings and their significance, but I honestly don't expect people to become a scholar about octane. All I really expect most people to do is to read the friggin owners manual. It tells you what kind of fuel you can safely run. You don't have to invest much time to read that...

BTW, I never said that I would run 87oct, I'm just saying that you can safely do it should you get the urge...

[audiwop]

--Adam

I agree Adam, I live out here in CA and the gas makes me want to go nuts. I'm for sure doing a W/M kit in the next month or so. But let me ask you this. Because W/M helps IAT's so much, what would happen if you ran it with87 or 89 instead of the 91oct? Wouldn't the W/M kit compensate for the lack of octain in 87 or 89?

[The_Jerbel]

Yup, it would be like running ~94oct...

if they dont get educated somewhat then there is going to be 132 and a half posts tomorrow saying

"put 87 in my tank cause my owners manual says its ok.. but why does my car feel slow?"

[The_Jerbel]

LOL, true true. I guess I should add that with the higher CF's, less timing, and worse fuel mileage, will also come less power and lower performance.

[1997gtx]

I would hope that people know by now that less octane = less power in general.

As I said, I would hope!
--Adam

[JDM EJ1 95]

actually that is very ^ untrue for most cars


most of your cars ecus are not as adaptive as ours.. not even close.. they could care less if you have 87/93 or plain water in the tank lol.

[The_Jerbel]

I'd be careful with that statement.
When running on a STOCK tune, yeah, most cars won't benefit at all from higher octane fuel. However, if you know what you're doing with the timing etc, you can get performance gains from almost any car.
