As you begin to dabble in the hobby and joy of RC (radio-control) vehicles and vessels, you might grow curious as to whether your RC car is really so different than that of your own motor vehicle. One question you might have is whether a nitro RC car can run on regular gasoline (the kind used for real cars.)\n\n\n\nSo can a Nitro RC car run on gas? It depends on the circumstances. If you are attempting to put regular gasoline in a non-altered nitro RC car engine, then-No it won\u2019t work properly. It will damage the engine. However, if you are retrofitting the car to run on gas, then it can run on regular fuel although maybe not at its highest potential.\n\n\n\nIf RC cars ran better on regular gasoline, they would be manufactured to use regular fuel. However, there is a reason Nitro engines are used in RC cars. To begin, it\u2019s helpful to understand the difference between how a nitro engine functions and how a gas engine functions.\n\n\n\nWhat is a Nitro Engine?\n\n\n\nA nitro engine is an engine powered by fuel that contains part nitromethane, mixed with methanol. The percentages vary depending on your vehicle. Nitromethane is a super combustible liquid that is generally only found in specific engines, like those used in vehicle drag racing, or miniature engines like that of a radio control (RC) car, or free flight model airplane.\n\n\n\nNitro is the shortened \u2018slang\u2019 for nitromethane used to describe these types of engines and is often heard as a marketing ploy or way to hype up a type of car or vehicle. Prior to being referred to as \u201cnitro\u201d engines, they used to be referred to as \u201cglow engines.\u201d \n\n\n\nGlow engines are actually fueled by methanol. The methanol is souped up with nitromethane to aid the performance and speed of a vehicle or vessel. The reason these types of engines were referred to as \u2018glow engines\u2019 is because the ignition system has a glow plug, which is a coil made of a platinum wire blend (often a mix of platinum-iridium). \n\n\n\nThe glow plug is heated via an electrical current, which gets things started. The residual heat and the catalytic action from the platinum alloy then mix with the fuel mixture and ignite the engine.\n\n\n\nWhat is a Gas Engine?\n\n\n\nA gas engine is a type of internal combustion engine that runs on gaseous fuel. Hence, it is referred to as a gas engine. An internal combustion engine is a heat engine (an engine that converts thermal or chemical energy into mechanical energy), in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. \n\n\n\nIn an internal combustion engine, the high-temps and high-pressures caused by the combustion chamber, send a force of energy to some component of the engine. That force is then applied to pistons, turbines, or a rotor. This force moves the component, turning chemical energy into mechanical energy.\n\n\n\nThe Clear Difference Between Nitro Engines and Gas Engines\n\n\n\nTo start, a nitro engine obviously runs on a nitromethane fuel mixture, which is alcohol-based (most common nitro fuel mixes are: 18% castor oil, 10% nitromethane, 72% methanol). On the other hand, a gas engine runs on regular gas, though even a gasoline engine requires oil. Another big difference between the engines is that gas engines have ignition systems, whereas nitro engines just have the glow plug. \n\n\n\nFor this reason, gasoline engines are also heavier than nitro engines \u2013 which is another reason one would prefer to have a nitro engine in an RC car. The lighter the car is, the better it will handle and the faster it can go. \n\n\n\nGasoline also has a significantly larger number of BTUs per unit of mass fuel than nitromethane as well. A BTU (British Thermal Unit) is defined as the amount of heat required to raise the temperature of one pound of water or liquid by one degree Fahrenheit. In other words, gasoline is more explosive than nitromethane.\n\n\n\nA nitro engine is also smaller than a gasoline engine. For this reason alone, it makes sense more RC cars run on nitro than gas. Additionally, since gas runs hotter than nitromethane, nitro engines require less surface area because nitro engines don\u2019t need as many cooling fans since nitro fuel is alcohol-based and pulls heat away from the engine.\n\n\n\nSo Why Won\u2019t Gasoline Work in a Nitro Engine?\n\n\n\nFirstly, nitromethane and gasoline are entirely different fuels that are not interchangeable. If they were, there would be no need to differentiate the difference between a nitro engine and a gas engine. They would just be called \u201cfuel engines.\u201d\n\n\n\nAs I mentioned above, gasoline holds a higher number of BTU\u2019s per unit than nitromethane. This is important because the Nitro engine is frail in comparison to that of a gasoline engine. Putting gasoline in a nitro engine will destroy the engine as it will conduct more heat than the nitro engine is capable of withstanding. The gas will not cool the engine down properly like methanol does.\n\n\n\nIn fact, if you were to dip your finger into a vat of gasoline fuel and then another finger into a vat of nitromethane fuel, you would discover that the nitro fuel feels cooler to the touch.\n\n\n\nIf you\u2019d like to see a real-time example of what happens to a nitro engine RC car when gasoline (petrol) is poured into it, you can watch the video below\n\n\n\n\n\n\n\nBut What if I Really, Really Want my RC Car to Run on Gas instead of Nitro??\n\n\n\nIf you are really passionate about running your small radio-control vehicle on gasoline instead of nitro for some reason\u2026you can tear apart the engine and put a small gas engine in its place (if the RC car is even big enough to accommodate a small gasoline engine).\n\n\n\nHowever, it is much simpler and much more cost-effective to purchase a true gas fueled RC car. When you go to buy an RC car \u2013 many non-electric RC vehicles will state that they are gas run. This often means \u2018nitro\u2019 fuel vs. actual gasoline. So be sure to read the specs on the back of the box and in the user ratings to discern which type of gas the vehicle runs on. While most RC cars run on nitro, you can find some that will run on gasoline. They are powered by spark plugs and operate much like gas-powered cars.\n\n\n\nA true gas-powered RC (or even a diesel fuel RC) is typically for someone who is quite familiar with RC cars for quite some time. I would not recommend pure gas-powered RC cars to the novice. There\u2019s just no need for it.\n\n\n\nIf you\u2019re looking to purchase a new gasoline-powered RC car, vs. retrofitting a nitro engine to become a gasoline engine, below is an excellent, top-rated gas-powered RC truck:\n\n\n\nRampage Mt V3 1\/5 Scale Gas Powered Monster Truck\n\n\n\nIt comes with a powerful 32cc 2-stroke gasoline engine, with a 700 cc gas tank, dual 1\/5 scale steering, and a rechargeable remote control receiving pack.\n\n\n\nThe Key Take Away?\n\n\n\nNitro fuel and gasoline are, without a doubt, two completely different fuels that require two completely different types of engines in order to run and perform at peak conditions effectively. You never, ever want to put gasoline fuel in your nitro RC car. The only time this would ever be appropriate is if you have completely gutted the Nitro RC car, and instead installed a gasoline engine, so that it is in fact gasoline compatible.\n\n\n\nAdditionally, if your heart is set on using an RC car run on gasoline, there are RC cars, trucks and even airplane models out there that you can buy that are designed to run on regular gasoline. For most people it is better just to stay with a normal Nitro powered RC car. They run perfectly great, are lighter and easier to operate, and will be less expensive. \n\n\n\nWhatever your choice is it is important to use the fuel that your vehicle is designed to use. That is the best way to ensure your RC engine lasts as long as possible and isn\u2019t ruined because you put the wrong fuel in it.
