Due to the crappy Fuel out here in Arizona i can only fill up Ms.Evie (my car) with 91 octane. Anybody have any good product out there that they use to boost their octane rating ? I am currently using "Outlaw" but it doesn't have an amount that it boosts the fuel to . Anyone using something (not an ALKY set-up) for octane boost they could recommend or find better than any other?

maybe this will help

 

Torco make a "race fuel concentrate", but I have no experience with it, might be worth looking into.

 

any octane booster is worthless. it will only raise your octane from 91 to 91.3 at most.



Formula #1 - Toluene
R+M/2.........114
Cost...........$2.50/gal
Mixtures with 92 Octane Premium
10%...........94.2 Octane
20%...........96.4 Octane
30%...........98.6 Octane
Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores.

Formula #2 - Xylene
R+M/2.........117
Cost...........$2.75/gal
Mixtures with 92 Octane Premium
10%...........94.5 Octane
20%...........97.0 Octane
30%...........99.5 Octane
Notes: Similar to Toluene. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Usually mixed with Toluene and advertised as *race formula*.

Formula #3 - Methyl-tertiary-butyl-ether (MTBE)
R+M/2.........118
Cost...........$3.50/gal
Mixtures with 92 Octane Premium
10%...........94.6 Octane
20%...........97.2 Octane
30%...........99.8 Octane
Notes: Oxygenate. Very common in octane booster products. Has lower BTU content than toluene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy.

Formula #4 - Methanol or Ethanol
R+M/2.........101
Cost...........$0.60 - $1.75/gal
Mixtures with 92 Octane Premium
10%...........94.3 Octane (Methanol)
10%...........94.7 Octane (Ethanol)
20%...........Not Recommended
Notes: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combine with water.

Formula #5 - Isopropyl Alcohol and Tertiary Butyl Alcohol
R+M/2.........101
Cost...........$0.60-$1.50/gal
Mixtures with 92 Octane Premium
10%...........94.5 Octane
20%...........Not Recommended
30%...........Not Recommended

Notes: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol.

 

Read an article in Super Street that said Gold Eagle's 104+ Racing formula will actually raise your octane several full numbers (not just a tenth of an octane) - but you might be better off buying 5 gallon drums of 76 Cool Blue and mixing.

 

What part of town are you from? I live on the west side, Surprise! I travel to 56th Street & Bell theres a Conaco that serves 100oct race fuel unleded!

 

these octane boosters are cheaper than gas...LOLz

 

Anyone have major chains they know of that carry Toluene and prices they hold?

 

In a recent article by SCC, they found that with 91 octane gas, NOS racing formula raised it to 93.7 and The Outlaw raised it to 92.4. They said that anything with MMT in it is going to be better than Ferosene or Toluene. They had to use almost 3 gallons of straight Toluene to get about the same reading as NOS Race Formula.

 

Could octane boosters cuase your car to misfire?

 

i think that yes they can make your car to missfire i used NOS octane boosters in my car and after some time i got a check engine took it to the dealer and it said it had a missfire code then we pulled out the plugs and they had a red color they clean them up and they put them back in rest the computer but days later of use i got the check light again but it comes and goes they told me i need to change my plugs due to this!!!!

 

Good info, thanks.

 

My car definitely runs better with an octane booster but NOS has MMT which is not recommended because it fouls plugs and sensors. I use it once in a while though and it works. I've tried VP 103 unleaded mixed in also, but it isn't cheap, is harder to locate, and you have to deal with more bulk and hassle.

 

i heard "MAG1 octane booster" works really well.
i heard it so many times from euro car owners.
but i can't find one in local shops....

 

a lot of these "octane boosters" contain organo-metallics, a metal, like manganese bound to an organic, a carbon containing group. The the metal when dissociated, will "poison" and mess up your oxygen, wide band sensors over time. Add toluene, add some 100 octane, water or water/alcohol injection.....just stay away from octane boosters.
