i'm not taking the chance...
The one thing this article doesn't mention is that while there isn't a difference in MPG between 87 and 93 octane gas in general, that isn't necessarily the case in practice, especially in high performance cars. Think about what most ECUs do when they detect knock...they retard the timing. Sure you can get away with driving around with your timing retarded...but you will definitely not be running as efficiently as you would with your timing at ideal levels.
So it may cost 30c/gal more, but you will probably get better mpg if you drive a highly tuned and/or performance car. Otherwise, use 87.
screw that the little sticker on the door of my gas tank says in bold big letters
PREMIUM FUEL ONLY i think i will listen to the engineer at honda that built the motor
NO NWS
my compression is 10.5:1. I'm not running regular.
right now, I have quarter tank of 93 and the rest 87. My daily that has 11:1 compression pinged like a ***** under WOT, lol. Had to drive home @ 60mph last night after filling up. Going to go buy 4 cans of octane booster today. I can't do 60mph, haha.
I ride a high performance bike. 93 all the way!
Except for today... I took my low performance bike. 87 rules, fools!
SORRY KIDS, the S2k is NOT getting anything other than that good good. i'll sooner call into work and bike around town than put anything other than that sweet sweet 93 in it!
11.0:1
2008 Ford Mustang GT (4.6L V8) - 91 octane or better recommended. Vehicle may safely run on 87 octane. Some engine pinging may occur, this is normal.
lol
bwhahahaha dude you can put apple juice in your tank and it'll work bwhahaha silly mustangs... as long as its liquid i'm pretty sure it'll @ least try to run... WAIT i've figured out a way to STOP EMISSIONS!!!!!
try and run the mustang on scope! MINT EXHAUST AND cool GREEN vapors!spread fresh and clean where ever you go!
yeah, doesnt quite work that way for all motors....my car would detonate at the first signs of boost

My car from the factory came with a sticker that says "Premium Recommended" and I can tell a difference between running regular vs. running regular. Let me tell you on regular, the fuel needle really moves. If I get 300 miles with regular I'm doing really well. And that's acutally driving normally. On premium, I get way better. I get close to 30 mpg on the highway with it. I filled up with regular and not only is it slower, but I'm probably getting about 22-24 mpg right now. Sux for me.Originally Posted by SpecV_Scott
K series 626. That's right. It's got a K in it.
You can tell a difference between running regular and running regular?
Back to being stock and slow
You do realize that, with 4 cans of "octane booster", you MIGHT raise it one octane point?
Back to being stock and slow
if ANY of you kids find premium.... i expect a phone call or a pm or SOMETHING!!!!!
There is some in Forest Park, by 285 next to BoJangles. Just got some.
Back to being stock and slow
well, as a last resort.... it would take me 1/4 tank just to get there lol... any near stone mountain or in gwinnett?
the miata pinged like a ***** on regular, but that was only after i bumped the timing up to about 18* lol.
the e30 likes regular though. 8.5:1 compression FTW!!!
The server is too busy at the moment. Please try again later.
If i put 87 in the evo, this is what would happen:
on a serious note, someone told me to get octane booster and put 87, lulz.
no thanks.
well, if that happens make sure you get it on video, ed. lol, would at least look cool for a minute...
Back to being stock and slow
right? lolol
With the shortage of premium, has anyone tried a mix of toluene? I remember reading about it before and used it at the track 3 years ago. I figured it may help since I did end up spraying that day
Currently, I have about 2-3 gallons of 93 left. I figured I can make a mix with 87 and toluene. If I did it now, it looks like I could end up around 95 octane.
yeah factory audi's can run on 87 but anything aftermarket including a chip you can't. You'll destory that car. And ran said something about his mustang and all i would run in that thing is 87 unless you were planning on racing something. Which in that car would be a stock ex civic.
Toluene will work but it's not very injector or O2 sensor friendly. It will eventually eat the seals out. Not immediately, though. Besides, that stuff costs at least $10/gal so for what it's worth, I'd ride out the regular until premium returns.
K series 626. That's right. It's got a K in it.
Yea, I've heard that as well. Its recommended to run some type of additive. I've heard you can use atf, but i've heard marvel's mystery oil will work well too.
why the hellz are you going WOT when you dont have the right octane in a car that needs 91+ thats like that hey im going to go WOT and see how close to 30psi i can boost creep to when stock is 9psi.... your smart.... NOT!

Ran the car with reg. Lowered average mile per gallon and ran like ****. Speaking from exprience, will not run reg again. Premium only on my turboed car.
i'm happy, just got a full tank plus a couple extra gallons of premium close by to me.
I'm not sure who else lives around the area, but Chevron at the corner of Redan Rd. and Panola Rd. has premium and regular. There wait wasn't bad at all either.
My Volvo is chipped (17psi) so I always use 93. I'm North Carolina right now and haven't noticed any gas shortages like in Georgia.

my car would run on dr pepper
Thank god. I didn't read any other post after yours, but guys, if you don't know what you are talking about, don't spread the misinformation.
And about E85. Since 1988 the Gov. mandated that all fuel systems be able to handle ethanol. So whoever mentioned that only GM, etc is wrong. Any car 1988 and higher will not suffer from running E85 through it. And also, be aware, that the 33% will probably require you to up the more then just your fuel map, 33% is a lot of fuel, so those of you already at 75% IDC, will need new injectors, and probably a larger, or dual fuel pump. Larger fuel lines as well. Then a tune.
E85 is not a drop in solution, and you cannot simply just mix it with your gas and go.
I would go on about the octane level, but I'm pretty sure someone else covered it already.

if i have to repalce the injector and fuel pump and a reflash to run E85 then the car CANT handle E85... and yes you can mix E85 and regular kinds of gas in a FlexFuel vehicle because the front O2 sensors (which really arent O2 sensors anymore more like Air/Fuel sensors and can read a much larger range than a O2 sensor) and read the car is getting leaner as the E85 is mixed in...

This is what I was talking about. This is not true. Of course you will need larger components. But I was referring to the fuel lines.

My manual recommends premium for my car, but I've put regular in it before. Maybe it's a psychological thing, but I feel like the engine sounds a little grittier...almost like a diesel, without so much clatter. Lately, I've been big-toeing the accelerator, so it's not like I'll feel any performance loss, if at all.
With mitsubishi's reputation for outstanding quality, i wouldn't be surprised if that happened anyway.If i put 87 in the evo, this is what would happen:
no thanks.
lirl. sad but it's so true.
