ls motor folks, accidently put 87 octane in my car today?
usualy i put 89 or 92 in my car but today when getting gas i pulled to a pump where it only had 87 and 92, i picked up the 87 thinking it was 89 since i havent noticed half the pumps are 87/92 and 89/92
is it really that bad? i guess i just wont drive like a bat out of hell with this 87?

Your going to be ok. It's not the end of your motor, there is no lead in it. 
Will you make something up for me please?

You have a stock LS, that's what they use. It's pointless getting higher octane gasoline. I used to run 87 all the time. That's regular around my area.
Regular = 87
Mid grade = 89
High = 91
Some places have 94 like Sunoco.

Correct. If you've been putting higher-grade gas in your car, you've simply been wasting money.

ever notice how the public is so used to "octane" ratings when such a tiny tiny percent of gasoline is octane? there are other hydrocarbons in gasoline, but 70% or more of it is trimethyl pentane, which gets labelled "octane" because it has 8 carbon atoms, although this name is incorrect because octane is only when those 8 carbon atoms are in a direct chain. only 5 are in a direct chain, hence pentane. call it a pet peeve.

they love me!! they really love me, first off i would like to thank god first and foremost for making this happen
the reason i put 92 octane in sometimes was i use to run a type r motor, and still this 7200 rpm is killing me

ehh, i did this a a experiment oned week, i ran a full tank of 93 and 87 though my car and the car on 87 was faster and got more miles to the tank. you want a engine to be on the verge of detonation. hell the ls are acually able to run 86.

87 is what the LS needs. if you want to run 86, i think only the civic VX motor claims you can use that. the closest you can come to detonation is where you will find peak efficiency.

Congratulations! In your attempt to be a smartass, you forgot how to spell, and have been quoted for the 3rd time.
And to adress the question, my 92 GS-R (B17) is only recommended to use 91 but may run on "regular" (89) fuel without damage, just a possible decrease in performance.

i still wouldn't do it. factory knock sensors are not known to be worth a whole lot as far as detecting small amounts of detonation. they do an okay job when the detonation is bad, but it wouldn't be that bad on 89 octane and the stock knock sensor probably wouldn't do much. you'd just see a loss in performance due to detonation (bad), not the backing off of the ignition map (not so bad). honda must have had a little too much faith in their knock sensors.

Knock indicator
I'm not sure if the earlier Hondas had it, but I know in the later ones, such as 97- Preludes ,00- Integra GSRs ,03- Odyssey and 02- RSX-s, the check engine light would blink to indicate knocking... it doesn't usually come on until the knock is almost detectable by ear or feeling...so I don't know how sensitive an early knock sensor is...just use the recommended fuel.
