well i know that it isnt recommended to use this gas for boosted vehicles(according to some of my friends) but why is it so bad to use this gas in boosted cars?
My friends sc'ed cavalier ran like absolute @!#$ at the track with Sams Club gas, it was sputtering and cutting out in the top end. He went through that tank and now only uses top tier gas and hasn't had an issue.
Then again I do have a friend who uses Sams gas in his TT GTO w/ alky injection and hasn't had any issues. Of course the car was tuned using that gas too.

Key is Alcohol.... Meth injection has been known to raise, depending on the octanes from 93 up into between 107 to 112..

Ummm no, the methanol content may help raise the octane slightly but it's purpose is to absorb the heat from the charge air. 107-112 octane fuel would be race gas, if that were the case no one would need it.
I've always stuck to name brand fuels in my boosted cars. Sunoco 94, shell 93 or BP are usually the only places I'll fill up.

91 octane and 50/50 mix raises it up to about 101/3 out here.
how is it changing the octane of the gas at all? and what formula are you using to come up with these ocatane numbers.
if you could just add liquids to make the gas have a higher octane then everyone would be using the octane booster in a bottle.
i understand thatthis prevents detonation when runnning wiht lower octane fuel. so the car is running like it has 1XX octane.
so what you did was basically add the 2 octanes and divide by 2???
all im saying is that spitting out octane numbers is equivalent to a butt dyno. adding anything doesnt change the gasolines properties.
exactly, go check out coolingmist site and read up on how it changes octane ratings...
i dont even see the word octane on their site
this is what it says
CONCEPT
At its most basic level, water injection or methanol injection is the concept of injecting or spraying a very fine mist of fluid (methanol, water, alochol or any combination) into your intake track or directly into your cylinders (Direct Port). The fluid will will atomize, evaporate and soak up heat. This process will leave you with colder combustion temps, colder intake temps and EGTs. This will lead to a safer vehicle, more power and more timing. The process of injection does not give you artificial power, but instead it gives you back power that you were losing due to the high temps and allows you to run your vehicle at higher timing load or boost or tune to gain significant more power.
it has nothing to do with octane
Actually adding ANYTHING to your fuel DOES in fact change its properties. If that were not the case fuel would never be fuel in the first place instead it would be sludge crude oil in your gas tank. There are MASSIVE differences between good octane boosters and bad octane boosters. MOST any octane boosters you can buy at your common auto parts store is garbage at best. There is a mathmatical way to figure out most anything........ octane boosting is one of them with of course margin of error determined by quality.
I ran sams club gas WITH methanol/water injection and it is bottom of the barrel get from point A to point B gas period. Results were no good at all unless driving normal. I tried it for the sole purpose of seeing how big a difference cheap gas makes and I was a little shocked as to how dramatic the difference really was EVEN when assisted with alternate means of enhancing its burn properties. The gas is plain and simply NOT pure stable gas for performance oriented vehicles. I dont even use it any longer for daily driving.
Make no mistake that those with the ability to test these products in real situation have and DO know what does and doesnt work.
CHEAP GAS IS JUNK GAS.................................................................unless you tune for junk gas then you can make what you can of it but it certainly is not at its peak of abilities.

Gas is made by vaporization. In a big tank, the differnt strands of crude oil vaporate at different rates. They then suck these vapors out, and let them condense. Now once again they are in liquid form and seperated from each other. There are some many differnt strands of gasoline, and these strains are called hydrocarbons. Later on these strains can be combined with the fuels to meet certain octane ratings and such.
Higher octane gas does have more additives in it than low octane gas. But these additives are generally detergents. Also, the cheaper gas has less additives in it too.
Another thing to consider is that almost ALL BRANDS OF GAS are delivered through the US by the same pipelines. A company can put in 500 gal of gas, but can immediatly withdraw that 500 gal of gas on the other side of the US. So therefore, they dont get the gas they put in.
That means that most places you go you get the same gas, except the difference in additive packages. Certain companys ship their gas by their own means, like Shell has its onw pipelines dedicated to Shell gas.

well since we are talking of octanes and the like figured i'd tell you that the chemical toulene is "i think" 112 octane when used straight but i know thats not practical however Audi used it in one of the race cars they built it ran on about 85% toulene i believe. So ive read it can be used as a cheap octane booster (read up on it though)
