No other fuel additive or octane booster has the specific lab, dyno, and track testing that’s gone into the development of Octanium! One bottle of Octanium can easily raise the octane level in your high performance vehicle from 93 to well over 100 – that’s a difference you’ll feel, at the track and on the street!

Okay, to drag this subject up, I finally had some time to run some of this stuff through a gas chromatograph and unlock some of its "secrets".

First, the (not so) obvious: Octanium is a methylcyclopentadienyl manganese tricarbonyl (MMT) based octane booster. In a nutshell, it uses manganese to increase the octane of fuel, basically the same way tetraethyl lead is used in some race gas.

So, unlike aromatic hydrocarbons like toluene and xylene, MMT can actually significantly raise fuel octane in small concentrations.

4oz of Octanium were found to contain 762 ppm of manganese, 13 ppm of magnesium, 2 ppm aluminum, 8 ppm iron, 3 ppm tin and 2 ppm silicon. My guess is much of the aluminum content comes from the aluminum can the stuff ships in.

So, based on the analysis of 4 oz of Octanium, each 32 oz can should contain about 0.72 grams of MMT. That means tossing a 32 oz can into an average 15 gallons of 93 octane pump gas should yield ~0.05 grams per gallon, which should increase the RON octane to roughly 98-99 octane. Slightly shy of the 100 octane they advertise, but, they never stated what volume of gas they mixed with to arrive at "100 octane", so I'll give them that one. However, if you're tossing it into 91 octane "limp-wristed fairy liquid" (aka Cali gas), you'll probably realize more like 96-97 octane.

On the face of things, from a chemical standpoint, it would appear that Octanium can increase the octane rating of fuel to a significant amount.

A few other points of interest, though: MMT, since it's 1995 un-banning by the EPA/Ecotards, is limited to 1/32 (0.031) grams per gallon of fuel. A can of Octanium will raise your MMT content well above this, which is likely why they mark the can as for "off-road use only". Further, while MMT is legal Federally, it's illegal in the People's Soviet of California, so you'd likely be put on trial for making a spotted owl cry or something if you use it there. (Assuming you get caught, which isn't especially likely)

Another caveat is that MMT is, ultimately, metal. So as with leaded fuel, prolonged usage will probably clog up cats (if so equipped), and may have an equally negative effect on 02 sensors. Still, given the bang for the buck, it's probably worth experimentation so long as you pull your 02 sensors every few months and make sure there's no build up or resistance changes or anything else generally unhappy going on.

One amusing trait, however, is that MMT will significantly reduce emissions of NOx, N2O and C02. I'm going to toss in two cans and try to pass emissions testing without a cat when I'm next due, for giggles.

Based on what I've seen in the chemical analysis, I'm feeling it's safe to use in most cars with no significant ill effects, and given that it's several times cheaper than tossing in a bunch of race gas, an attractive option assuming there are no long term negative issues.
