what octane gas you guys run on ? thanks!

 

i used 91 octane all the time and thinking of going back to 89 only when the gas price goes up to $4 lol
and if your gonna ask me which gas station, i go to chevron
and one of the gas station here in LA is selling 100 octane (racing gas) but its too pricey $8 per gallon but i wanna try tho even just once

 

91 since on the gas door it does day "premium fuel required" and especially more now since my car is tuned.i never once put anything lower than 91 NEVER

 

yeah i use 91 octane also with shell or chevron and Mobil.

Its a shell in santa monica i beleive cant recall. i went up there with my freind to pump 100 in his 180sx.

thanks.

 

what car you got btw? im guessin an EK with a k20 swap?

 

the one that i saw is by the pasadena freeway (110N) by the end of the freeway

 

dang gas sucks where you guys live lol. we have 93 as a standard here in MD. 87 the lowest 89 in the middle

 

Anybody who has a K20A3 should be using 87 octane fuel as you will not see any benefits from using 91. The A3 isn't tuned to use 91 octane fuel like the A2!

 

thats true tho a3 is not tuned but i use 91 just to the benefit of cleaner gas

and 91 is for old engines and engines that have 100+ mileage

 

where do people get this info?.. wtf

 

Well actually, your ECU will tune itself in a way to adjust for using premium gas. I've always used premium gas in my EP. The day that I let a buddy drive my car of course he fills it up before he gave it back to me and he used 89 when he did. Not only did I notice my car didn't perform or run as well, but it also got worse gas mileage.

I've heard a lot of things about what gas a car should run but definitely never heard this before...

 

your only kinda right and still mostly wrong.

 

like kobe said, all i have around me is 93. car calls for premium so that's what she's gettin.

 

lol we have good gas!

 

Ya but Kobe doesn't have an A2 in his EP so it's kinda pointless to be putting premium fuel in a car that wasn't designed to run it!

 

Yes the ECU will adjust itself but for optimal performance the A3 should use normal unleaded fuel. The ECU wasn't really tuned to use 91 octane.

 

Clarify? I would rather be completely right lol, so what's the correct info??

 

i only use 93. i thought that since its a cleaner fuel that it would help with a cleaner burn inside the combustion chamber. i know that the ecu could adjust slightly for the difference in fuel. i also thought that the higher octane fuel would reduce the risk of detonation, especially when you are the type of driver that drives hard often. not a 100% on that though.

 

this is true.

 

91 all day everyday regardless of price...;]
oohh and shell v-power cuz its rite dwn the street frm my pad

 

well i been runing 93 oct since the day i got big jimbo, if i switch to 87 will it **** wiith my car?

 

91 with 3 ounces of Lucas every oil change.

 

i use a can of bg MOA on every oil change i got the hook up at work lol and free oil! every 2k i change it

 

i use 93 and i want to change my fuel lines so i can start to run E85, the stations are coming up more around my area.....

in any eveny i am pretty sure the has been answered.....can we get a close on this thread

 

actully in la there is a gas station by LAX on supulvada blvd that has i beleve a chevron with a 106 octane 9 bucks a gallon out of a barrel lol
