Can Engine Oil Be Ignited by Fire?

[Steven]

Engine oil can be ignited if there is a carrier with an open flame, as it inherently possesses flammable properties. The detailed explanation is as follows: General properties of engine oil: Typically, engine oil does not spontaneously combust, but it is flammable by nature. Therefore, if there is a carrier with an open flame, it can catch fire. For safety reasons, it is best to avoid exposing engine oil to open flames. Note the flash point of engine oil: The higher the flash point of engine oil, the lower its volatility, meaning it is less likely to ignite even at higher temperatures. If the flash point is too low, it can pose a potential hazard, so this aspect should be taken seriously.

I once accidentally spilled some engine oil onto a hot engine in the garage, and it actually caught fire! Engine oil is a petroleum product and is inherently flammable. Its flash point is generally above 200 degrees Celsius, and when the temperature is high enough, it can ignite upon contact with an open flame or heat source. In real-world scenarios, oil leaks coming into contact with the high temperatures of the exhaust pipe can potentially cause a fire, which is extremely dangerous. A friend of mine had car parts damaged because of this. However, engine oil isn't as flammable or explosive as gasoline—it burns more slowly. I recommend all car owners regularly check for oil leaks under the chassis to avoid accidents. Used engine oil should be properly recycled—never play with fire yourself. Safety first!

With years of experience in auto repair, I can confirm that engine oil is indeed flammable as it's a hydrocarbon, similar to diesel. Under high temperatures, such as when the exhaust pipe reaches 400°F, leaking oil can spontaneously ignite. Our shop has encountered several small fires caused by customers neglecting leak points. Always wear gloves when handling it and keep away from open flames; never dispose of used oil improperly—take it to recycling centers. Make it a habit to quickly check for oil stains under your car before each startup to prevent potential hazards.

Bro, engine oil can definitely catch fire! I once tried burning a drop with a lighter, and it slowly ignited, just like a candle. It's oil after all, with a specific flash point. Don't be silly and try this at home—things could get out of control. If you smell oil or notice a leak while driving, pull over immediately to check. This stuff becomes dangerous when heated in the engine bay. Simply put: it's flammable, but not easily, so just stick to regular maintenance.
