Last of all now we have Nitromethane as our main fuel. Here we have three additives to help with preignition and or detonation.

Methanol in Nitromethane. Since Nitromethane has itself a tendency to pre-ignite and detonate, the sole object of up to 10 percent Methanol as an additive is to reduce this tendency to detonate while having only a minor effect on pre-ignition.

Water in Nitromethane. Up to a maximum of 2.5 percent as this is the maximum amount that will mix without separation taking place. It reduces both preignition and detonation due to the internal cooling effect alone.

In practice a combination of Methanol and Water is the better use of the two additives, the proportions being 2.5 percent water and 7.5 percent Methanol giving a good safe usable blend of Nitromethane, with almost the full power capability of undiluted Nitromethane.

Acetone in Nitromethane. Up to a maximum of 5 percent. This reduces preignition by raising the auto-ignition point and any small decrease in detonation is incidental.

Yeah, but the fuel most of us run contains 70 to 84 percent methanol...
