Put 87 octane in my Nismo :(
 

First off has anyone ever done this before? Secondly I know I'm retarded for doing this. Most importantly what should I do? Put octane booster in the tank? No pinging sounds as of yet. Is it really necessary to try and drain the $70. Of gas I just filled up with?

Why'd you do that?..

Just drive completely normal for this tank and you'll be fine. That means no pedal to the metal.

I drove to Vegas this weekend and put two tanks worth of 87-octane into my girlfriends Scion. Today I go to fill up my Z and some sexy chick walks right by me (sexy as in the Carl's jr. Commercials kind of sexy) and distracted me. Didn't even think twice about pushing the 87-octane button :(

That sucks man

Well at least you have a good excuse.. Lol you should be fine though

That's gonna be tough but I'll try. I had an orange Z car just try and race me on the freeway and my lead foot was itching to hit the pedals!

Is octane booster worth trying?

Definitely not worth it. Wouldn't hardly change the octane at all. Don't waste more money.

If it were me, I'd syphon but yeah a tank probably won't kill you

One tank is not going to make a difference. I certainly wouldn't make it a habit but you've got nothing to worry about. Just take it easy on the pedal and try to empty the tank as much as you reasonably can before you fill up again.

Do what everyone says.

I'd siphon out the tank though. But yeah, no pedal to the metal, or you risk detonation in these extremely low tolerance motors.

There are also REAL octane boosters, which might be worth getting if you're paranoid.

i wouldn't worry about it, just drive it like grandma for this tank. wouldn't recommend making it a habit tho

:icon18:

All of you guys would really siiphon off 17-20 gallons of gas??? JEEZUS you guys need to find something better to do with your time...

I think you should drive like a human, drive on the tank, then when you fill up next, disconnect your battery and wait about an hour or so to reset the computer

Kill half the tank and go back to fill up with 91/93?

just drive slow man/

To be honest, your dealer probably put in 87 too cause most sales people are dumb.

Thanks for the advice everyone. Gonna do the wait till half a tank idea and fill up with 91. (crossing fingers)

Good choice.

Lucky she did not distract you to fill it with Diesel :roflpuke2:

just drive normal lmao

one tank isn't going to hurt

ahahahahahahahahahahah

if its available, pump 100 octane into your car at half tank, that should make it about 91 octane after the mix but it might be a bit higher or lower

just take it easy though

It's fine. It even says in the manual that it's okay to put 87 octane gas in an emergency if there's no higher octane. Just don't keep repeating it.

Nope. A gallon of toluene is however. Its in the paint section at Lowes.

- b

I would probably trade it in for a new Z...

jk it will be fine

Your car will blow up in 3..2..1.........

whoever said siphon off the tank.... completely unnecessary. the car will be fine as long as u arent goint WOT all day

:iagree:

But I would use at least 93 octane. When mixing octanes of equal volume the resulting octane mix an average of the 2.

Example: 9 gallons of 87 octane + 9 gallons of 93 octane = 18 gallons of 90 octane

http://en.wikipedia.org/wiki/Toluene
Cheap, effective and safe octane booster.

Ya think?

It goes on to say:

"Toluene also poses similar problems as alcohol fuels, as it eats through standard rubber fuel lines and has no lubricating properties, as standard gasoline does,[citation needed] which can break down fuel pumps and cause upper cylinder bore wear."

Won't be going in my tank.

its a trick the some of the built volvo dudes use, but i stil didnt wanna do it.


some old tuners swear by toluene tho

Modern cars all have knock detection, precisely because the OEMs know people may put lower octane gas in their cars, either by mistake or necessity. Drive as normal. The car will adjust ignition timing to compensate, resulting in lower hp and mpg than normal, but no damage.

Don't put weird, cheap octane booster in your car. You'll do more damage than just running on regular low octane pump gas.

You know, the owners manual actually tells you what to do if this happens.

Why is it every time I see someone recommend resetting an ECU the time "requirement" keeps going up? An hour is just ridiculous, 15 seconds is all it takes to reset ANY processor. It's not like you have to bore the ECU to death with no power for it to reset.

I saw a silver Nismo on Victory in Van Nuys/Sherman Oaks whatever... I smelled 87 when I drove by it... tisk tisk...

I always thought it was an hour, my bad...

I put Toluene in my car all the time, I use it here in CA where we get 91, in TX, not so much, they get 93

Definitely a case of RTFM... :icon17:

Having said that, sh$t happens....drive it empty and refill with the good stuff. Not a big deal. :tup:

This:icon18: - and also read the manual before dumping it here and telling us how you couldnt street race. Note - improve your driving skills before adding another mod to your car. Street racing AINT the way to do it. No sympathy.
