Quick Facts"},"content":{"rendered":"\n
Have you started to notice your car is leaking oil, and concerned the leak might cause a fire? Is motor oil flammable? <\/p>\n\n\n\n
Motor oil is not a flammable liquid, but instead a combustible. Temperatures need to reach 300\u00b0 to 400\u00b0 Fahrenheit for motor oil to combust and burn. In fact, motor oil is among the least flammable fluids with a flashpoint of 302 to 392 degrees.<\/strong><\/p>\n\n\n\n But this doesn’t mean that leaking engine oil is not<\/em> capable of catching fire, it just requires a much higher flashpoint<\/a> to burn. Flashpoint refers to the temperature at which a flammable liquid vaporizes, or is able to ignite.<\/p>\n\n\n\n For example, motor oil that leaks onto the vehicles exhaust manifold has the potential to burn and cause an engine fire. <\/p>\n\n\n\n In fact, an exhaust manifold can reach extremely high temperatures \u2013 in some cases, even upwards of 1200\u00b0 Fahrenheit. This is well above motor oil’s flashpoint, and a recipe for an engine fire.<\/p>\n\n\n\n If you think there’s even the slightest chance that your car could be leaking motor oil, take it to get checked out right away. It’s always better to be safe than sorry!<\/p>\n\n\n\n Now, let’s take a closer look at some of the surprising facts regarding the combustion properties of motor oil. <\/p>\n\n\n\n Let’s dive right in!<\/p>\n\n\n\n Without getting too scientific, motor oils have long hydrocarbon chains. As a result, they’re difficult to break down. But that doesn’t mean they can’t catch on fire under certain circumstances.<\/p>\n\n\n\n For example, if you spilled some motor oil<\/a> on your BBQ pit and then lit it, the oil would probably catch on fire. <\/p>\n\n\n\n Motor oil can easily burn when there is the right amount of heat.<\/p>\n\n\n\n Different materials can burn in different ways. Some materials, like gasoline, can burn in the air. This is because their vapors are combustible. <\/p>\n\n\n\n Other materials, like motor oil, need to be in contact with extreme heat before they will ignite.<\/p>\n\n\n\n To be considered flammable, an object has to ignite at 200 degrees Fahrenheit<\/strong>. However, oil ignites at a much higher temperature.<\/p>\n\n\n\n The OSHA Laboratory Standard<\/a> defines a flammable liquid as any liquid having a flashpoint below 100 degrees Fahrenheit<\/strong>. <\/p>\n\n\n\n Whereas a combustible liquid is defined as having a flashpoint at or above 100 degrees Fahrenheit<\/strong>. <\/p>\n\n\n\n A vehicle’s engine is designed to operate within a normal temperature range of 190 to 220 degrees Fahrenheit. However, depending on the make and model of the vehicle, this range may vary slightly. <\/p>\n\n\n\n Engine temperature is regulated by the cooling system, which consists of a water pump, radiator, and thermostat.<\/p>\n\n\n\n Some car fires have been caused not by leaks, but instead from a catastrophic engine failure. For example, if a connecting rod inside the engine fractures, the broken parts may crack the engine block. <\/p>\n\n\n\n An engine block that has a crack will allow motor oil<\/a> to escape and drip onto hot engine surfaces. Surfaces such as the exhaust manifold or catalytic convertor can easily exceed 1200\u00b0 Fahrenheit. As a result, dripping motor oil on these surfaces will lead to a fire.<\/p>\n\n\n\nWhy Isn’t Motor Oil Flammable?<\/h2>\n\n\n\n
