What You'll Learn
Nitro fuel is made of methanol, nitromethane, and oil
Nitro fuel, also known as nitromethane, is a type of fuel used in motor racing, particularly in drag racing, and for radio-controlled models. It is made up of a combination of methanol, nitromethane, and oil.
Nitromethane, with the chemical formula CH3NO2, is an organic compound and the simplest nitro compound. It is a polar liquid that serves multiple purposes in industrial applications, including as a solvent, reaction medium, and cleaning agent. In the context of fuel, nitromethane is the primary ingredient in "Top Fuel" drag racing. The oxygen content in its molecular structure allows it to burn with significantly less atmospheric oxygen than conventional fuels, making it suitable for high-speed engines.
Methanol, on the other hand, is often considered the best alcohol-based fuel and can provide a power gain when used in racing engines. It has a BTU/lb of approximately 9,500. When mixed with nitromethane, methanol can enhance the power of the engine, as the limiting factor is often the air intake. This makes it easier to tune the engine by adjusting the air-fuel ratio.
The addition of oil, typically castor oil, serves as a lubricant in the fuel mixture. This is crucial for the operation and maintenance of the engine.
The combination of methanol, nitromethane, and oil creates a potent fuel mixture that can significantly increase engine power and performance, making it a popular choice for racing and high-speed applications. However, it is important to note that nitromethane fuel is not meant for everyday use in conventional cars and is primarily reserved for specialized racing vehicles.

It is used in racing, especially for RC cars
Nitro fuel, or nitromethane, has been used in racing since the 1930s. It was first used in model tether-car racing, and today, it is used in radio-controlled (RC) cars, as well as full-size race cars.
RC cars, also known as nitro RCs, can be powered by nitro fuel. This is a fuel that contains nitromethane, which is a powerful ingredient that can increase the performance of the car. Nitro fuel for RC cars is available from various brands, including Traxxas, Dynamite, AquaCraft, and VP.
Using nitro fuel in an RC car can be more work than using other fuel types, such as electric or lithium polymer (LiPo) batteries. This is because nitro fuel requires more maintenance and can be more difficult to work with. For example, nitro engines require stronger internals to stand up to the higher output and corrosive effects of nitromethane.
However, some enthusiasts prefer nitro RCs because they enjoy the tinkering and skill development that comes with maintaining these cars. Additionally, nitro fuel can provide increased power and performance compared to other fuel types. The percentage of nitro fuel used in an RC car may depend on the engine size, with larger engines typically requiring a higher percentage of nitro.
Nitro fuel has a rich history in racing, and its use continues to evolve, especially in the world of RC cars.

The percentage of nitromethane in the fuel will differ
Nitro fuel is made up of methanol, nitromethane, and oil, and it is available in cans or bottles at hobby shops. The type and amount of oil in the nitro fuel determine whether it is better suited to RC cars and trucks or RC aircraft. True gas-powered RCs are typically 1:5 in scale or larger and have spark plugs instead of glow plugs. They run on gasoline mixed with motor oil, just like a regular car.
It is important to note that switching nitro fuel is a matter of trial and error. It is recommended to avoid switching if you are new to nitro RCs. Changing fuels will almost always require re-tuning your engine. When choosing nitro fuel percentages, it is crucial to consult the manual that came with your nitro RC to check the recommended percentage. If the manual does not specify, seeking advice from a local hobby shop is suggested.
Additionally, it is important to be cautious when making changes to the percentage of nitromethane in your fuel. While small changes, such as 5 percent or less, are generally safe, larger changes can be harmful if your nitro engine is not properly tuned. For example, going from 10 to 20 percent can cause issues if the engine is not tuned for the higher percentage. Similarly, reducing the percentage from 20 to 10 percent will result in decreased performance and may require additional tuning.

It is readily available by the can or bottle in hobby shops
Nitro fuel is readily available in cans or bottles at hobby shops. It is a mixture of methanol, nitromethane, and oil, with the addition of anti-corrosion agents or degumming agents. The percentage of nitromethane in the fuel varies between 10% and 40%, with 20% being the typical amount. The oil used can be castor or synthetic, and it is added to provide lubrication and cooling. The type and amount of oil in the nitro fuel determine whether it is better suited to RC cars and trucks or RC aircraft.
If you are new to nitro RCs, it is best not to switch nitro fuels as it can cause issues with the engine. Changing fuels will almost always require re-tuning your engine. The manual that comes with your purchase will specify the recommended percentage of nitromethane for your RC vehicle. If the manual does not provide this information, you can consult your local hobby shop for advice as their employees often have experience with RCs.
It is important to note that the scale of the RC vehicle can also indicate the type of fuel it requires. For example, a 1:8, 1:10, 1:12, or 1:18 scale model vehicle likely has a glow engine that uses nitro fuel, not gasoline. On the other hand, true gas-powered RCs are usually 1:5 in scale or larger and run on gasoline mixed with motor oil, similar to regular automobiles.
When choosing nitro fuel, it is recommended to stick to the same brand even if the nitromethane percentage varies. This is because different brands may use varying types or percentages of oil and other additives, and switching brands and nitromethane percentages simultaneously can be detrimental. Small changes in the percentage of nitromethane, such as around 5%, are generally safe and do not usually damage the engine. However, larger changes can harm the engine if it is not properly tuned.

It is not recommended to switch nitro fuel if you are new to nitro RCs
If you are new to nitro RCs, it is not recommended to switch nitro fuel. Nitro fuel is made of methanol, nitromethane, and oil, with the percentage of nitromethane in the fuel varying between 10 and 40 percent depending on the vehicle type. The oil added to the fuel could be castor or synthetic, and it is used to provide lubrication and cooling. The percentage of oil in the fuel is typically not disclosed by the manufacturer, but it can range from 8 to 25 percent, with 15 to 20 percent being the standard.
Before switching nitro fuels, it is important to refer to the manual that came with your purchase to see what percentage of nitromethane and oil the manufacturer recommends. If the manual does not specify, it is advisable to consult a hobby shop for guidance, as their employees often have experience with RCs. Changing nitro fuels can require re-tuning your engine, and using the wrong fuel can lead to a decline in performance or even permanent engine damage.
Small changes in nitro fuel, such as a 5 percent difference, are generally safe and will not harm the engine as long as you closely monitor the RC's performance and make adjustments as needed. However, larger changes, such as going from 10 to 20 percent nitromethane, can be detrimental if your engine is not properly tuned. It is also important to avoid constantly switching between different fuels and to stick with the same brand of nitro fuel, even if the nitromethane percentage varies, as different brands may use distinct types or amounts of oil and additives.
In summary, if you are new to nitro RCs, it is best to avoid switching nitro fuels unless absolutely necessary. Refer to the manual or seek expert advice to ensure you are using the correct fuel for your specific RC, as this will help prevent performance issues and potential engine damage.
