Just wondering how many people use Octane boost in their cars? Does long term use affect any of the sensors or burn them up, like the O2 sensor of AFR sensor? Now that 94 octane is close to my house I mix 1 bottle with every tank and now have no detination issues.
Just looking for everyone opinions, and maybe a POLL would be nice but couldn't figure out how to do it. Can some one set up a POLL. thanks

Tune your car for whatever octane gas you have readily available.
If your car likes 94 octane (ethanol blend) and you want to use that, then "tune" for 94.
If you plan to use 91 octane then "tune" for that.
Octane boosters are a bandaid fix at best and most don't work as well as they claim.
If you are getting detonation, go after the source of the problem (too much boost? too much timing advance? carbon buildup? your sparkplug heat range? etc.). |

just go to home depot pick up a can of toluene and mix it into your gas at a percentage of 15 or lower.
it is already found in pump gas and has a ron+mon/2 octane rating of 114
that is if you need it;) |

| Octane boosters don't do anything they might add 0.2 of an ontane to the gas. |

Also, watch using that ethonol 94 octane... I've heard it burns quite hot. |

| Guys on the MR2 board have talked about using toluene as well, and seem to think it's just fine. |

I ran 94 ethonol blend for a while and ran fine but like you said it ran hot hindering my TMIC.:mad: I run 91 usually esso or shell and seem to run a lil cooler. |

Toluene is very corrosive to seals and will eat all of the o-rings in an injection system.
There's more to it than that, but that's the coles notes.

P.S. Race gas by the barrel FTW! :neener: |

Um.. guys... you know that Toluene is already a constituent of normal gasoline, right... ?

all you guys saying toluene is bad are wrong.
its found in gas at the pump
its completely safe up to 15% mixture for all rubber.
the stuff you stay away from is its cousin xylene;) |

Enthonol burns slower and cooler then regular gas, 94 is all i can run in the srt under 20 psi of boost, anthing else and i ger mad detionation |

Yes, I know this, but I was speaking to pouring it in your gas as an octane booster. Like I said: "coles notes". You can do it if you want, but I don't recommend it. I'd love to give a full write up on toluene as an octane booster, but I have other things to do right now. Maybe later.

This is a generalization and is not completely correct. I would be wary of using the words "completely safe" when making that statement. Toluene affects things other than rubber as well. There's a lot more to it than can be found in simple statements like this. A little internet research can go a long way, or better yet, reading up on chemistry.
Cheers,
Tim. |

| I only run octane boosters if I get a bad tank of gas and my car is acting up till I can burn off enough bad gas and get some good stuff in the tank.. |
|

| Rich_A |
| is there any safe way to up 91 octane gas to 94? |
|
|

An octane booster will do it.
I grabbed a quick article that is relevant to this topic. Enjoy.

that is what i heard as well
hence why i only pump ion 94 octane
on and pS it benefits the club just got our 1st gas check
buy gas at mohawk/husky and support teh club |

Here, go buy some toluene from home depot.
Then take any injector o ring and fuel hose.
Throw them in a clear container with toluene.
Watch for as long as you want because it will not eat rubber.
Toluene is used to make rubber and a whole bunch of other substances.
I excelled at chem in high school so I tired it myself because i too thought it would eat rubber.
Now repeat it with xylene;) |

Valve burning is decreased when ethanol is used because ethanol burns cooler than gasoline. Many high-performance racing engines use pure alcohol for that reason.
Ethanol blends are approved under the warranties of all domestic and foreign automobile manufacturers marketing vehicles in the United States.
Using a higher octane or AKI fuel will not increase gas mileage unless the engine is knocking or pinging with the lower octane fuel.
a search on google shows alot of forum talk about the topic .. including www.albertagasprices.com
end conclusion after i read all the articles & reports, ethanol is the way to go.. it mandates in few states taht theya re required to use it as part of the clean air act....blah blah read all about it do your research on google..
there will be few out there saying views are biased but i have not found info saying ethanol is bad or anything like that..
methanol well taht is diffrent story |

good read, but I can't make out the table as to which brand of octane booster is better, and by how much it increases the octane :dunno: |

| Interesting, I find my car runs hotter on Husky 92 octane as compared to running regular 91 oe 92 octane. |

Ethanol will run leaner and hence hotter at the same volume of injection. You need to increase the ammount of fuel injected to get your AFRs back to the right level. Your o2 sensor should take care of this for you on a stock engine, or you can tune it out. |

......... Home Depot Toluene is your friend.
100% agree with McFly and Inzane.
P.S Add another couple of chem degrees to back it up. |

all pre 1989 cars should be capable of it due to the beggining of blended fuels.
ie. husky 94, mohawk 92, pretro 91.
the eastern united states is already overrun with it and its price varies. There are over 600 stations with it in the tanks.
Edit: back when f1 cars were turbo used to run up to 5 bar of boost running on straight toluene:thumbup: |

Hmmmm No O2 sensor :P
I just dyno'd(with a wideband) and I'm not running lean or anything.. Normally I smell gas at my tail pipe, it smells like I'm running rich.
AFR is something to do with a fuel rail right?
My wife's Neon with Multiport direct injection, I can switch between reg fuel and husky without any noticable temp diff. Going from Husky 92 to Husky 94 makes no diff either.
Both cars are supposed to run on 91+(Premium) Hers cause the Advanced timing and the magnum head, mine purely cause of the swirl port heads |

| Not sure what issue but SCC had a big write up on octane boosters some months back, the home mix worked best (touline), followed by NOS octane booster, then STP and the other cheap crap. |

I know its a old thread
I have been trying to read as much as possible on ethanol blends. A have found alot of places(over the last few weeks) that say how when ethanol hits the O2 sensor it sees it as alot leaner = richer mixtures when you ecu compensates.
It turns out that husky is E94, E= ethanol belnd.
Shell has E87,E89, 91
Most ppl will say at WOT it doesn't read the O2, but 200 km for s1 is shitty and I rather have shell 91 and use MMT.
What MMT?
So far what I have read was MMT(methylcyclopentadienyl manganese tricarbonyl) (MMT is a arifical octane booster) is in alot of gas, because in Canada it does not have to report if they use it.
It turns out that MMT is only bad for your Cat. which alot of us don't have, so who cars right?
But beware
"Levels of MMT beyond the recommendations of booster manufacturers will foul spark plugs, damage oxygen sensors (O2S) and plug catylitic converters. High percentages of MMT contaminates engine oil and leaves hard metallic deposits in the combustion chambers, piston tops and upper end of the cylinder walls such that engine wear is greatly accelerated. Do not use them in concentrations higher than suggested by their manufacturers."
lets see your options! |
