Nitromethane, conversely, is a simple and potent chemical compound with the formula CH₃NO₂. The result is a power-to-weight ratio that is utterly unmatched in internal combustion, making the comparison to standard octane ratings somewhat reductive but necessary for discussion.
Debunking Octane Myths: Why Nitromethane Doesn't Fit the Standard Rating System
For this reason, fuels used in Top Fuel dragsters are often described as having an "octane rating" of 120 or higher; nitromethane allows these engines to operate on the edge of what is physically possible without tearing themselves apart. Practical Blending One of the most fascinating aspects of nitromethane is its built-in oxidizer.
It is composed of a single carbon atom bonded to three hydrogen atoms and a nitro group (NO₂). This number quantifies the fuel's resistance to "knocking" or "pinging"—uncontrolled premature explosions within the engine's cylinders.

The Oxygen Advantage One of the most fascinating aspects of nitromethane is its built-in oxidizer. The question typically arises from a desire to compare the energy sources that power extreme combustion engines, from dragsters to top fuel dragsters.
