discussion about octane additives
I'd like to hear some opinions on Octane additives.
I always thought they were useful and although pricey, a way to get into a higher octane fuel thus, less pre-detonation, etc etc.
Some comments on these boards lately have made me think there might be a reason to believe they do not work well.
Tell me your thoughts please.

wow, have you looked at the owners manual for your car?
Does it not call for minnimum 91 octane?
Its well agreed that anytime you can get 93 octane in these engines its a good thing. Now to take that a step further, many mods that you do cause a lean condition, that is fact. Lean causes hotter temps, pinging and dangerous pre-detonation. All facts. The way to combat that is higher octane fuel which was created for the purpose of addressing this issue.
in addition, those of us who have bumped up the timing via a fuel mgmt system once again are looking for as high an octane fuel as we can get.
For those who have timing advanced, and mods, using a higher octane fuel only seems prudent.
That is not my opinion brother, its common knowledge, lets be real.

Unless you are running some extreme tune (which would be foolish in the first place), or a FI setup, the addition of octane boosters to the premium fuel that is readily available would likely be a waste of money.
We are all aware of the reasons for having high octane race fuels. My curiosity arose from wondering if you really thought you needed it for the mods you have or were just looking to add it to your tank in the misguided belief you'd get more power or there was some other easily recognizable gain that might be had.
Are you experiencing pinging or extreme timing retard? Have you measured or monitored A/F ratio to see if it's actually too lean?

Hey I understand.
I agree with you on the additives, I think they are junk.
I was really looking to create a dialog about them to see what others thought.
MY car is tunned and not running lean due to my FMS device.
But may are after mods and not addressing the A/F as you know.
Your points are well taken, mike

You do realize it would take over 10 bottles of regular octane booster to bring 15 gallons of fuel up just ONE point, from 91 to say 92. Don't waste your money, it doesn't do ****.

Actually the NOS one raises the octane by 60 points, which = 6 octane numbers (On octane bottles 1 point = 1/10 of an octane), IE 93 octane to 99 octane. (Can't vouch for the actual result, just what they claim)
However thats the only one I've ever seen that actually raises it more than one or two, most say "Raises 10 octane points!" which is really just raising by 1 as others have said.

Believe it or not, the Z with normal bolt on will not have an issue with octane. Modern OBD2 computers will adjust for mods, they may not be optimal (like a tune is) but your engine will not be damaged.
91 to 93 octane, they car is tuned from the factory for 91, that means you will gain nothing from going to 93 without a change in tune.
We can actually safely run 89 or 87 in the Z's without problem, there are a few people who only put 87 in theirs without problem. I run 89 in mine on long freeway trips, constant throttle, cruise control set for a couple hours, who cares.

I use stp octane boost . I do not use it where I live because I can get my 93 oct all the time. But when I travel it is a big problem to find anything over 87 in may places in the midwest . My car it tuned for 91 so thats why I have it and yes it does help. It' much cheaper to add 2 btls of this stuff than a 15k engine. This is the only 1 I have found to do anything.
