Race gas contains many chemicals that fall into three primary groups Fuel Hydrocarbons, Oxygenate, and Organometallic Compounds. Each group of compounds is found in typical gasoline. What makes RACE GAS different are the individual chemicals that were chosen from each group. While our exact recipe is proprietary (patent pending) we can share the family of compounds used and their relative properties.


Put simply, fuel hydrocarbons are compounds that contain both carbon and hydrogen that, when oxidized (burned), produce water and carbon dioxide. Saturated hydrocarbons have a high octane rating and contain additional carbon atoms which produce more energy during combustion. When combined with certain organometallic compounds, the fuel hydrocarbons in RACE GAS have synergistic effect to produce higher octane ratings than if they are used alone.

Oxygenates are one of the most misunderstood compounds in gasoline. While many have heard of the negative effects of oxygenates like Ethanol and Methanol not all oxygenates are created equal.

Oxygenates play a very important role in high octane gasoline. Like the name suggests oxygenates add oxygen to gasoline. By adding an oxygenate to RACE GAS, it adds crucial oxygen to the fuel which, in turn, creates more efficient combustion and the fuel is burned more completely. This allows the advantage of more energy released by the fuel’s combustion of the additional carbon atoms added by the hydrocarbons found in RACE GAS. The net result is more horsepower!

The oxygenates that are used in RACE GAS are not derived from alcohol (like methanol or ethanol) and therefore do not damage fuel system or engine components.


Organometallic compounds are added to gasoline to increase the octane of the fuel. Up until recently, tetra ethyl lead was used in gasoline for this purpose. In addition lead was used as a lubricant on older engines that didn’t have hardened valve seats. The problem with lead in gasoline (other than the environmental effects) was the fact that scavenger compounds needed to be added to gas in order to keep the lead from creating deposits on pistons and cylinder heads.

When the US Government banned lead in gasoline, refiners turned to other metallic compounds like manganese, iron, nickel and magnesium. We believe that manganese has the best effect on octane and the synergistic effect with the other compounds found in RACE GAS. As a result RACE GAS contains the highest quality methylcyclopentadienyl manganese tricarbonyl or MMT.
