Company that makes it is called VP.
Says to add one bottle for 20 gallons of gas.

Trying to find ways to up the octane of the poopiety 91 octane gas here. Would this booster work or will I have to mix in real race gas?

You may want to hunt down JB over on the Induction Forum..He uses an Octane booster..I don't recall the name of it but he says its great !

I used octane booster in the past, and I believe it was the root cause for both of my front O2 sensors failing at different times. When the first one failed after the first few tanks of octane boosted gas, I thought it was just a fluke, but once the other one failed too, I thought it likely that the octane booster was the culprit. Since replacing the second sensor, I have been mixing in Sunoco 104 unleaded and not using any octane booster, and have not had any more problems. The octane booster I was using said that it was safe for O2 sensors and cats. I guess not.

I am using Turbo 108 racing fuel concentrate ($2.99) from Auto Barn. It works great and makes a noticeable difference especially if using less than 94 octane gasoline. It has also been recommended on this forum by Shawn at LAPD.

I can't find the article right now but you need a whole of liquid to move octane up much. Check the labeling on cans of "octane boost" most only give a point or 2 of octane boost per can. Which means, for several dollars, you can go from 91.0 to 91.1!

For mixing racing gasoline I think can use a simple formual for mixing in racing gas as, I believe it is proportionate. For instance mixing equal parts of 100 octane unleaded with 91 unleaded will yield 95.5 octane.

i would stay away from all the boosters you find in the parts or performance store. most contain NAPTHA which leaves a nasty rusty-brown residue all over the combustion chamber on down to the O2 sensors. Instead use Xylene (116octane) or Toluene (117octane). you can find 1 and 5 gal cans of either at a local paint store such as Miller, Parker or Rodda Paints. you can make a nifty chart for mixtures and desired octane levels using simple algebra, but, 2 parts 92 octane pump gas to 1 part Toluene makes 100.4 octane.

I get 5 gal cans of either xylene or toluene from local paint store for $25. that is $5 a gal. I dump 2.5gal in my tank when i have only 5 gal left leaves me 100 octane. So that works out to $21 for 7.5 gal of race-level gas (5 gal of 92 octane here in Portland, Or is 1.70gal + Toluene @ $5/gal), which comes to $2.80/gal!!!. MUCH cheaper than the $8/gal for race gas at the track.

:iagree: :iagree: I used this formula when I was running my G.N..

Stay away from the octane boosters in auto stores, they don't raise your octane enough and are expensive.
Heres a helpful link, used Toluene in my super charged truck, only get 91 octante here. Helped a lot with a pinging issue I have. Sherwin williams carries the stuff to.

:iagree: :iagree: I have tried it. Wasted two sets of plugs. I used the 101 you buy in stores. Leaves this red gunk on the plugs and screws up the fuel tables. I did not see any increase in anything. When autocrossing I try to get there with a half tank of fuel, I would dump a bottle in (yes they said a full tank of gas, but I figured hey if a little is good more should be better :bb :cry ) Cost me a perfectly good set of NGK double Ps and a set of Delcos (I could probably clean them and use them again.) She would run good at the event, as I would run the tank out I would get a low and rough idle. Higher RPMs were ok, but no noticeable increase in performance.
