Since gas station around area does not have anything higher than 91 octane. i was just wondering after getting my procede v2 who know when will it official release and install on my car with the boosted additive fuel thing like Boosted Fuel from NOS , prestone , and whoever company make them.. I saw those boosted fuel additive that they are selling at the auto zone or other place. they Claimed " give u "10 point on the octane.." for example 91 octane that u have .. pull and mix it with the gas to 101 octane. it should be boosted for speed n gas consumption is better. Should i buy it and pull it in and dyno with the procede to see how much i can pump max (whp/lbs torque)..

here are

Yes or no? Actually do they work at all.. i have doubt about that stuffs from auto part place.

[PresaMat]

From what I hear it doesnt do much of anything

[AM335]

I do not believe these additives can take 91 octane up to 101 octane.

[imolazhp_ci]

i actually know a guy will a fully built EVO who's car was built for 100 OCT. and the shop who built it for him told him... look you HAVE to put at least 100 in it and he was like yeah yeah i will... well he blew a cylinder out the bottom of the block and when he brought it back to the shop he had a case of octane booster in the back of his trunk and said "well i thought it was the same thing...." guess it's not.

I've seen a test done of these additives, they in fact did very little.
They DID however raise octane a bit.
(They tested several different gases all with 91 Octane and got readings of like 90.8 to 91.2).
After trying different Octane Boosters they tested the fuel again and got like 91.6 to 91.8

Toulene (spelling ?) is often the driving force of Octane boosting.
I believe it's illegal to use more than a very small amount in gas additives (as I'm guessing the pollutants are to blame) but Toulene will in fact boost octane.

Those additives often harm other aspects of your engine however.
Your best bet, find a gas station in your area that sells race gas.
From time to time, if you choose, add 2-3 gallons of 100+ race gas to your tank then fill up with 91 Octane and you have 93 Octane in your car.

Don't waste your money on those "boosters" to gain what would be like 2-3 hp at best from them, but do more harm than good to your fuel system.

The one that works is called Torco, raises 91 octane to around 96 octane (verified by octane labs). It's expensive, around $13 per can, which treats 10 gallons. I used to run it in my supercharged corvette a lot, but haven't had the balls to try it in the 335.

Thanks Terry, I couldn't remember the name of it.
I believe Torco is heavy on the Toulene isn't it?
Never used it personally.

Not sure, it's super secret. I used to be a big skeptic over on CorvetteForum.com back in the day until they did the octane testing with it. Impressive stuff.

Everything else is a joke though; you're better off adding 1 gall 100 octane to a full tank.

[Sleepr335]

If you read the fine print on most octane boosters, it will probably tell you something like "10 points equal 1 octane rating". They don't do very much.
EDIT: This is directly from Prestones website about the 0 to 60 octane booster that the original poster was aking about. Read the very last paragraph: http://www.prestone.com/carcare/faq.php#q7

[zenmaster]

I think you need a heated O2 sensor if you want to use leaded gas though. Also bad for the cats.

Sport Compact Car did an article on this June 2005 issue. They tested a few octane boosters. The only one that showed any type of significant gain was the NOS Racing Formula (off road) which raised the octane from 91.2 to 93.7 (+2.5). It's not cheap at abut $8-$10 bottle. They tested toulene and with a 30% mix (about 4.5 gallons in a 15 gallon test batch) it went from 91.2 to 95.5 octane, but at above 30% it caused some issues (toulene vaporizes & combusts slower).

In their tests, the NOS Racing Formula (using MMT) boosted octane from 91 to 93.7. I have ran 2-3 cans of it through my car with no obvious ill effects.

Wow, maybe that NOS MMT formula really works. What does a can cost?

I have been paying ~10 per can. If I recall correctly, that treats about 15 gallons or so. The testing company appeared to do a very thorough job and I have been pleased with it so far. I haven't had any instances of knocking or anything odd. Of course, I do only have 1,600 miles on my car since November.

[bmwzimmer]

They have NOS octane booster (racing formula) at the local autozone store for $10.99. Since most folks here in Cali are running 91, anyone here have success with this stuff? I don't want to use Torco and have my injectors turn orange obtaining 100 octane race gas is a PITA.
This test result looks very promising...

From the Gasoline FAQ
http://www.faqs.org/faqs/autos/gasoline-faq/part3/

6.18 How can I increase the fuel octane?

Not simply, you can purchase additives, however these are not cost-effective
and a survey in 1989 showed the cost of increasing the octane rating of one
US gallon by one unit ranged from 10 cents ( methanol ), 50 cents (MMT),
$1.00 ( TEL ), to $3.25 ( xylenes ) [108]. Refer to section 6.20 for a
discussion on naphthalene ( mothballs ). It is preferable to purchase a
higher octane fuel such as racing fuel, aviation gasolines, or methanol.
Sadly, the price of chemical grade methanol has almost doubled during 1994.
If you plan to use alcohol blends, ensure your fuel handling system is
compatible, and that you only use dry gasoline by filling up early in the
morning when the storage tanks are cool. Also ensure that the service station
storage tank has not been refilled recently. Retailers are supposed to wait
several hours before bringing a refilled tank online, to allow suspended
undissolved water to settle out, but they do not always wait the full period.

[bmwzimmer]

Is it safe to use the NOS stuff? It's currently more cost effective and convenient in my area as 91 octane is currently $3.60/gallon. 100 octane will run around $7-8 a gallon and I would have to drive a distance and put 3.5 or so gallons to obtain 93 octane. Just using this stuff should raise it up to 93.X and is so much easier. Anyone use this stuff regularly?? any issues?

[Evo8MRto335I]

The way to go is water,alcohol or methanol injection. Either that or buy a few gallons os Sunoco delievered to your house in 5 gallon drums.

Those power additives alter the final mixture to a minimal upgrade, not worth much at all.

[Black Chili]

Find a 76 station that sells race gas and add some 100 octane from the pump. It's not cheap, but you'll be getting some real gas instead of another additive package on top of whatever is already in the gas.

A general list for the area: http://personal.linkline.com/dbarton..._in_SoCal.html

[Dustin Bramell]

Stick with real race gas or bit of toulene. Although, keep in mind that toulene lacks a lubricating agent, which means that it can dry out seals. On the other hand, being that the 335 is direct injection, there are probably very few rubber seals throughout the fuel system.

Torco works much like toulene, and also may cause issues because of the lack of lubrication. But the number one reason not to use torco is that it will turn all of your internals orange. If a tech ever took apart your car, and found an orange turbo, an orange exhaust, and orange spark plugs, they would probably void your warranty right then and there, no questions asked, as right or as wrong as that may be.

Here is some good info I remember reading back from my Audi days. Hope you brought your reading glasses....

Toluene is the correct spelling . You can buy it in gallons or 5 gallon containers at Sherwin Williams.

Do a google search and you can find the mixture recommendations.
