RC Glossary

Nitro (1) Nitromethane Fuel --

"The fuel used in model (RC) engines - contains methyl alcohol, nitromethane (hence 'nitro""""), oil (for lubrication), and other inert ingredients. Nitro fuel is rated by the percentage of it's nitromethane content, with 10%, 20%, and 30% being the most common. The nitro percentage used in a given engine depends on the engine's compression, but as a rule of thumb: 10% is used for micro engines (such as a .05), 10% - 25% is used in small blocks (such as a .15), and 30% or more is usually reserved for big blocks (such as a .21). In general, the higher the nitro percent, the more power produced. The percent of oil in the fuel is also important, as this indicates the amount of protection for your engine. Oil content usually runs between 6% (for racing fuels) to 10% (for hobby fuels). Nitro fuel is hydroscopic (it attracts water), and may loose some potency when exposed to sunlight. So, keep the lid on and store it in a dark, dry place."
