I was talking to a guy with another FD who says he uses octane booster on every fill up and I should do the same. He says since CALI only has 91 octane now, that the booster is better for the engine. Then I talked to a mechanic friend of mine and he says that doing that would burn up a piston motor but he's not sure about rotors. So......whats the verdict?

if you do that prepare to go broke, those tiny ass NOS octane boosters are upwards of $4 a bottle. i think they may be more then that actually.



not sure of any adverse affects so cant help you on that side of things.

Octane boosted plus 91 octane should be fine.

rxrotary2_7 01-16-2003 10:46 AM

those tiny ass NOS bottles are BS. try using xylene. it is 117 octane. when the NOS bottles or any of those claim to raise it 8 points or something... this would mean if you started with 91, you would end up with 91.8 dont know exactly how far the bottle strechec either. do a google on xylene.

yeah those thing false advertise. Most people think it will raise 91 to 99.

I know ricers that have those pieces of **** on hand at all times... LOL

does anyone here actually use xylene? im curious but a bit scared to try.

jackdhammer 01-16-2003 11:58 AM

Don't know about Xylene, but NOS was dyno proven to add hp. Check Import Tuner, early 2001 issue.

I think I'll try octane booster the next few fill ups and see how it does.

rxrotary2_7 01-16-2003 11:58 AM

i do.

I've used xylene before. Home depot has small cans of it. 30% xylene should bump you up to about 100 octane. If you need that much octane, just run race gas or aviation fuel.

rxrotary2_7 01-16-2003 12:47 PM

it can get expensive using xylene. i used to be a painter and i still get the discount. it cost $6.99 a gal. ihor, using that much of a mixture is not recomended. i dont think it is *safe* to go to much over 25%???

thats what i was thinking why not just buy race gas? Is it that spendy?

just curious here... how do you plan on "seeing how it does"?

Silver Ninety Three 01-16-2003 02:06 PM

Thats why i just said to use race gas.

rxrotary2_7 01-16-2003 03:06 PM

i know... i was just pointing it out to those who will read this and go and try to make like 116. https://www.nopistons.com/forums/pub...DIR#>/wink.png

See if my car runs better, cleaner, smoother,.....different. Race gas is like 5$ a gallon vs. 91 at 1.60 + 3-5 dollars for booster is a nice alternative if you want to run higher octane than 91

rxrotary2_7 01-16-2003 06:06 PM

maybe you didnt read what we were saying about the "pep boys boosters"... they are Bull ****.

i am sure import tunner magazine was PAID by someone to do that artice. none of us are being paid by anyone to say otherwise... octane itself wont make HP. it will allow you to do things you normaly would not be able to w/ a lower rated pump gas. the higher the octane the slower it burns. i am not going to type out an entire class on octane, do a bit of research on it.

good luck w/ your test. https://www.nopistons.com/forums/pub...DIR#>/wink.png

oh, and dont take this as an insult to you, that is not what it is trying to be. i am not very good w/ wording things. just doesnt seem like you are getting it.

Hehe... you know, this guy is right on the money with what he says...

Actionhank 01-17-2003 01:27 AM

my friend uses xylene in his supra and he likes it. He siad use about 1 part xylene to 5 parts gas. so like 3 gallons of the stuff with a full tank of gas. he likes it. I would only go about 2 gallons a full tank though. I plan on doing it if i ever race.

jackdhammer 01-17-2003 01:42 PM

No offense taken :bigok: I think I will research the whole octane issue a little more. I just brought it up because everybody was bitching when they dropped to 91. So that made me curious about supplemental products.

oh, and thanks sinful7. btw feb. 11th's answer is B.

Nightwolf463 01-18-2003 06:12 PM

I didn't read the other posts but I can tell you that octane booster uses microscopic particals of Magnisium to cheat the octane rating so if you want little pieces of metel running directly into your motor have fun.

amp 01-19-2003 09:14 AM

imho..

id mix high octane race fuel to increase if your limited to 91..

elevation is another factor to consider...

my trip from CA to NJ resulted in not seeing anything above 92 till the eastern portion of TX..

had to use octane boosters... as race fuel was not convenient....

just note that race fuel is leaded and your o2 sensor at this point is susceptible..

that is..if your still retaining it..
