What kind of gas do you use in your car?

[2.25CrushBent]

What octane? what compay?

i use 89 Shell

[Loudpedal]

87 Octane in the winter when the winter tires are on
89 Octane in the summer when the summer tires are on

Usually Shell, or Petro Canada

[FurY]

When I first bought the car, I was using regular but I have since switched over to premium. The car runs smoother for me and I get better gas mileage.

[dj addicted]

93 chevron

[HondCivc91]

I was using 87 Texaco for a while but then I moved less than a mile away from a Super Wawa and I've been getting 87 there for the past month and a half. Gas has kinda increased to from 31-34mpg average. I found that interesting.

[Civicvtec1ps]

89 mobile.

[Ep3 No.2]

91 octane
nothing beats "chevron with techron" =OP

man o man i wish they sold 93 octane over in cali.

[2.25CrushBent]

Yah, i heard that on the East coast they get 93-94

[AzN Si GuY]

DIESEL........ hahah j/p I use regular. :D

[the JigGa mAn]

93 octane from shell

[enecks]

the cheapest stuff i can find...

[plpong893]

93 from mobile or exxon

[getch74]

93 octain. which ever is the cheapest around.

[JapanExpress]

93 from BP :cool:

[mysiismyBABY]

I was just gonna post a thread asking the same ?. My b/s'n buddy told me higher octane could burn your valves faster depending on what kind of ride you have. He told me to ask someone who knows for sure (that's how I know he's full of s**t). So the highest octane is the best as long as it wont mess up my car right? Gas here in so cal is at an utterly rediculous price right now too... it SUX!

[tom3]

Take a look at this article here:
Octane: What it is for... (http://www.hondalife.com/modules.php?name=Sections&op=viewarticle&artid=17)

I learned something new from it tonight.

[estebones]

92 most of the times from your average Diamond Shamrock but I always go for the 93 where I can find it.

[BlackEp3]

i use 69 octane

[tbone_ep3]

I get premium, only the best for my skank, car runs smoother and I get better gas mileage.

I have read many other similar articles.

According to this author, if "your compression is 9.5:1 or lower, 87 octane should be plenty" then our car which runs 9.8:1 (correct?) would be best served by running 89 octane...??

G

[Me ep3]

Shell El Premo
Some times mix half and half with 103 from gas city $$$$$.

[BlackSi613nin]

i use 93 from either shell, bp, or marathon, where ever im closer to or where ever its the cheapest..

joHn

[dchu]

Always Chevron 87 oct. Gonna bump it up to midgrade 89 for my next tank. I get some pinging at the top of 3rd gear. Hopefully that will take car of the pinging. I'd hate to have to buy 91 premium because it's about $.30 more expensive then 87 around here. One of the reasons I bought this car was the trouble free good performance with crap low grade octane...so much for that benefit.

I would love to see more literature or a nice grit about compression ratios vs. octane ratings. Anyone? I'm looking around, but haven't really found anything valuable yet.

[CaTiRo]

man, the ep runs on 87 but i have to use premium in my 00 si. :( if my car ran right on 87 i would use it. oh well.

[speedking604]

94 octane chevron

93 mobil

[Grookes]

I just realized I didn't answer the questions - 87 Rotten Robbie mostly. Gas is gas in California. It all comes from the same 3 refineries. The big names throw in some additives, but ... well ... don't care.

[beechstreet]

the cheapest 87 that I can find, which is usually at ARCO/AMPM

[YooShin]

Wen't from 89 Oct @ Diamond Shamrock to 87. Really noticed a diference so I switched to Shell 93. BIG difference. Really smooth, and less intake back fires. Exhaust doesnt stink anymore either.

[Accordexcpe95]

Premium since day one.. watch the gas price jumped from $1.4x to $1.8x.. :( i think i should use 87

[02SiFoLife]

87 cuz the gas prices are hurtin bad.
2.29 per gallon ? WTF !!!!!!:mad:

[Sirone]

Man do I feel bad for you Cali guys, 2.29 for gas? The last couple of weeks in missouri gas price has run from 1.57 for reg, +.10 for mid, +.20 for premium 93, all the way to a not so stunning(Cali compartive) 1.75 or so for reg.... Anyway..

I run midgrade 89 in my car. The intake occasionally backfires at this octane, I am assuming it is because of the octane being 89 and not 93.. but I am not exactly sure that is the reason. I just think that sometimes because of the intakes(CAI Injen) propensity to consume huge gobs of air, if you hit the gas at the wrong moment after you accel it throughs off the sensor and causes that backfire.

[aRz]

i just payed 2.07-9 for 93 octane MOBILE 1 Premium.

BUT only the best for my baby
mobile 1 is the shit :cool:

[clubsi]

only 93 octane. sunoco, mobil, or shell in a pinch.

[03silverEP]

Amoco 93 (i refuse to call it BP) my car gets better gas milage w/it, seriously on 87 my low gas light would go on at 210 now it's 225-230,

clark: didn't her eyes used to be crossed eddie?

eddie: yup, well clark she got kicked by a mule, eyes go crossed... falls down a well they go back again, i don't know

[MoThanEnoughNY]

93 octane all day!!! Chevron Sunoco or 'Amaco' lol

102 octane from Sunoco on race night. ;) lol

[Trimix]

87 octane, Chevron or 76. I try to stick with TopTierGas cause dont know what they put into the other stuff.

[ALL MotoR Ep3]

I use 93 octane all year round....

[NitroBoarder]

93, usually fill up at BP.

and it's hilarious to see the posts from 2004 bitching about gas prices. I would kill someone to get prices that low...seriously.

[MugsyTheGr8]

this thread is hilarious. i hope all you guys running higher than regular have kpro tunes, f/i, cams, or k20a swaps...

[socmex7]

Man do I feel bad for you Cali guys, 2.29 for gas?

i would KILL for those prices.... :mcry:

[Ep3T0n3y]

I heard once that the engine is mapped for 89 stock.
Since its the average lowest on the east coast, so i just put in 89.

And then add pure Techrol

[BlownSi05]

93 octane since i have the s/c:mtongue:

its a nightmare on the wallet though:mcry:

[jimmyjames]

93 Shell V power
(I'm SC'd so I need it)

[4angrybadgers]

87 octane when I had just bolt-ons. That's all it needs and anything more would have been a waste.
93 octane now, because of the JRSC.

[SLOW EP3]

Why would you use 89 octane? That's like saying...I'm not a total cheapass so I'll just use mid-grade.

I use Shell 93 V-Power on my NA'd turdbox to keep the internals fresh and clean. If you read the owner's manual, it's *recommended* to use a fuel with detergent additives (aka v-power).

[jdm_ep3]

i use 87 only since my car is stock and putting 91 would just be a waste of money! only go to cheveron, shell, 76!!! never arco or valero haha unless its an emergency

[somejaykid]

87 cuz my car is bone stock

[wil524]

87 octane, Sunoco or Shell if I can get it.

[dbnow88]

I get 31 mpg with 93. what's this about getting 210 miles to the tank. I get 280-300 if I push it

[T_Virus]

chevron 87 unleaded with basic bolt ons...

[Unknownally]

87 cuz the gas prices are hurtin bad.
2.29 per gallon ? WTF !!!!!!:mad:

Ah yes, the good ole days.

[Soviet]

Ah yes, the good ole days.


No kidding...

It's like, WELCOME TO 2008!!! PWNED!!!!:meek:

[SilverStar]

91 Octane since Day1

[civictype_r04]

93 from sunoco.

[Jsoto517]

Yeah gas is so expensive, i use the cheapest crap. my cars stock so f**k it.

[SiR R8TD]

The Z1 only gets Sunoco 94. Damn these bullshit gas prices are hurting bad.

[RedSiBaron]

uhh, dude sorry but octane has nothing to do with quality unless you are buying, for instance, the shell 93 with the cleaning agents...

93 is the wrong octane for the stock a3...using 89 doesnt make you a cheapass if its the correct octane for the car...

the octane has to do with flame propagation and using the wrong octane in a car means the cylinder will be firing too early or too late and create a knock situation, you might not hear the knock, but it would still be present...

it has nothing to do with gas quality or mileage you would get...

[todaamann]

V Powa'

[blkep3man]

i use regular right n0w, usually use the 89 plus. gas prices now a days i dont like to see me hit the $40 on the display at the gas station. :usa:

[sinful]

i use regular most of the time. every month i treat my baby to some premium. :mbiggrin:

[PuMpKiN_Ep3]

my baby gets pampered with Chevron Supreme :biggrin:

[frm_808]

91 octane all i seen in lv. i think plus is a waste. not many people use it which i think the fuel sits longer than reg and premium

[Type Stephen]

3 of my 4 cars use premium. lol :x

05 Lotus Elise - 30mpg
05 Outback - 24mpg *regular
02 Rsx - 27mpg
97 A4 1.8 - 23mpg

I guess its not too bad with the gas mileage everything is running. I guess I should trade the outback in for an sti to be more consistant. :D Lol.

Shell/76/Chevron

[rsy124]

When I still had the EP..
Shell only - 89, or 91 depending on gas prices

For my BMW E36 325i - 91 only since the chip is mapped for it, otherwise some knocking might occur...Not sure if I like Chevron or Shell for it yet

[SI in GA]

I use the cheap stuff "89".

[az-epdrvr]

always 91

[ravinggoofy]

93 shell

[eunsangie]

running with 87 mobil or exxon.
get about 280~300 per tank.

[thevietkid33]

93 either sonoco or cumberland farms.
can you beileve some old guy was flipping out at me for putting 93 in my ep3. he said"big v8's dont even use 93 and yoru putting that in your little civic?"he told me it was the biggest waste of money he ever saw.

[NitroBoarder]

did I see you a few weeks ago while I was filling up at the intersection of 113 and 29? I was filling up at the BP there, and remember seeing a SSM 04-05 EP turning onto 113 from 29. my buddy lives in souderton, so I'm down that way occasionally.

[civic sir f1]

i use the dirtyest of the dirtyest of gas its got to be better than mexican gas right? as long as my car runs on it i use it. Dont care what brand. if its arco or pemex dont care as long as the honda engine turn on it thats all i care about.

[shelbz]

always regular.. cuz i'm cheap.

[thevietkid33]

[SyckSiR]

94 oct mowhawk gas

143.9 per litre yesterday :mad:

[Passenger]

Plus does it for me!

[MugsyTheGr8]

HAHAHAHAHHAAHA wow, people are dumb as shit...i love how most people dont have a clue what octane ratings mean...
alot of people in this thread have no idea...

[jdmbm]

i only get gas at bp's, premium 93 octane.

[RedSiBaron]

alot of people in this thread have no idea...

yah, i failed misserably in another one of these threads, i know how it works, but i cant explain it...dont know the right terminology...:mconfused::mfrown: not just hte knock resistance part....bleh

[ts ep3]

i go with 89 chevron:tongue1:

[MugsyTheGr8]

yah, i failed misserably in another one of these threads, i know how it works, but i cant explain it...dont know the right terminology...:mconfused::mfrown: not just hte knock resistance part....bleh

haha. all octane is, is the antiknock properties of the fuel. here are a few reasons to switch to a higher octane, or things that would require different octane ratings


high compression
advanced timing
leaner a/f ratio


if you are running a stock k20a3 which requires regular grade fuel, you will not see an increase in performance or any better millage by running mid grade or premium fuel. and, any change in the "smoothness" of your motor is all in your head.

the way i see it, its a plus that the ep runs regular and is as fun to drive as it is. all the cars that came out at the same time as the ep that were in the same class required premium.

[renovator]

93 Sunoco, Gulf, or BP for me.

[PaTTi2103a]

87 cuz im cheap :mtongue:

[hyjnx]

only the best for my baby =) 93

[robhep3]

93 Shell or BP...

I'm running the Hondata High-Octane tune with my k24a1 headswap... Makes noticeable power and gets between 26 and 32 mpg routinely...

[L337Ep3]

87 Chevron

coulda sworn there was also something to do with the flame propagation...but i guess i could just be crazy...which is very likely

[mrpotatohead]

93 octane

[Twisted-X]

I was always told that the higher the octane the slower the fuel burns, which to me would mean that its less likely to prematurely explode (due to high compression or carbon build-up on the piston heads=knock) before the spark plug ignites it. I've been using 89 octane Shell lately because subconsciously I buy the "v-power" BS :mwink:

[RHCP0801]

with gas at $4.09 for 87 im using 87 lol, some places are $4.11 and more

[shllipperybert]

i use chevron w techron ahaha good for the i-vtec :mtongue:

[AllSlowNoGo]

I use regular

[irrational]

89 from cheveron or 76

[skoo74]

91... pricey but yummm premium

[irrational]

91... pricey but yummm premium
Blah..........Misa Campo is "yummm premium" :mtongue:

[ryko]

the cheaper the gas....the better (on my wallet)

[itsanep3]

I use 93 from Chevron, or BP on some occasions. Can't use anything less with boost...

[bunk]

87 FTW until I get my swap.

[matdbom]

shit, my broke self uses 87

[chewie_jrc]

Just graduated college, still have loans to pay off...I'll be using regular for awhile :)

[EPandaman29]

mobil 91

[sleepy_ep]

shell v-powa 91

[Blaine]

The cheap kind...

[jayl33]

usually 89 from Shell or whatever is close

[Candy Core]

99 shell vpower

[EPSU3]

87, why i chose the ep over the em1.

[AFG]

i tried the whole premium thing for a while. the car felt better, maybe it was just in my head. problem is that tanks went by much quicker, and the cost now is KILLER! $4.35 a gal!

[jimmy`]

regular, gas prices are so expensive! :mredface:

[paulmofyourhand]

petroleum :rofl:

[iDOMO]

premium:crutch:

[smoody]

regular, with gas prices this high. whatever runs my car now

[hatchman]

i use 93 ultra fom sunoco

[T-MacK]

94 ultra......on both my cars!

[brownryce]

kind of gas: pregger farts...nothin more potent...

lol (89 octane, wherever its cheapest + fuel cleaner every 3000 miles):flame:

[Ep3T0n3y]

kind of gas: pregger farts...nothin more potent...

lol (89 octane, wherever its cheapest + fuel cleaner every 3000 miles):flame:

yeah i use fuel injector cleaner every 1000 miles
I read somewhere that in large citys gas is more shity, because they know they can get away with it by people needing fuel.

[Sub]

I alway put 93.. My buddy tells me it a waste of money, but with gas like it is i just stop looking at the price.

[Elise98]

87, There is no need for anything higher.

[HondaMat2Si]

87 cuz the gas prices are hurtin bad.
2.29 per gallon ? WTF !!!!!!:mad:

LOL

Oh and I use 87 cuz the car is made to run on that.

[QUEEN]

I used to use Plus, but with the ridiculous gas prices now, I have resorted to Regular.

[Bobster3825]

I know it doesn't help but I use midgrade... Just makes me feel better:mwink:


Bobby

[na14yu]

I put 89 in the EP from the time I bought the car in 05 until about 3 months ago when I switched to 87 exclusively for the EP.

[drjd888]

87 since thats all it needs

[mr-alternative]

87 octane gasoline...WTF...spec here is for all EP versions ( 1,2,3) minimum 95...better can be, but are no must.

[Dbl-Htch]

Always used premium in all of my cars for as long as I can remember...maybe I'm wasting $$, but at approx. 20 cents more per gallon, 15k miles a year, 30mpg average...it works out to around $100/year, or like $8/month.
About the same $ as eating fast food once a month, which I hardly ever do...
:mconfused:

[Twisted-X]

I've heard it said on other car forums that using a higher octane gasoline can speed carbon formation in the motor. Anyone have any experience with this?

[mr-alternative]

Here in germany we have the K20A3 engine in some 5 door civic, it has got in here the same power as you have it in your Ep3.

Gasoline stations here have got 91 octane, 95 octane and premium gas with 98 octanes.

Honda sys for gasoline: use 95 octane gasoline, 98 octane gasoline will not decrease or increase your engine power, gasoline which has lower octane could also used for "getting home", but engine would have full power and needs more gas...

[RS_man]

I use plus because the owners manual states that 87 and higher is ideal for this car. I have tested many different gas types in my area and can now only put Shell's 87 gas in my EP. She's a picky gal.

Yeah...thats true...the msot expensive gas by "ARAL" is good for her...but Shell's one is I quess ok for her, but not the best...

[rsy124]

89 Shell for my EP3 when I had it
91 Shell or Chevron for my E36 (we don't get 92 or 93 here =[)

[Honad]

The only time anything other than 87 has touched the nips of my injectors is during track days. Simply because by both tracks that I frequent only the Premium is non-Ethanol blend. The 87 and 89 are both E10.

Anyone who isn't running a FI setup or doesn't have a ECU flash specific for Premium and is running anything other than 87 is just wasting money. From the factory, your car is tuned, ready and wanting of 85-87 octane. It runs worse and gets less milage on higher octane fuel.

[frankthetank]

87 octane:mcool:
