Is Synthetic Oil Flammable? Learn The Facts!

We can all agree on the importance of motor oil when it comes to the engine since it serves as a lubricant. What it does is ensure that the moving parts of the engine don’t wear quickly due to friction.

However, one of the most common questions we’ve been asked is if synthetic oil is flammable. Well, the answer is yes, but at a significantly lower degree.

In this article, we are going to explain everything you need to know about synthetic oil and what makes it flammable. So, continue reading to learn more.

Is Synthetic Oil Flammable?

Yes, synthetic oil is flammable. The truth is that all oil all flammable but at a lower degree. However, when it comes to synthetic oil tends to have a higher flash point when compared to regular oil, which means that it actually needs more heat to be ignited.

As you can see, synthetic oil is much safer, but you should still take precautions when handling and storing it. It’s always best to keep it away from high temperatures and open flames and ensure that it is properly disposed of when finished using.

So, even though synthetic oil is considered to be less flammable than regular oil, it still has the potential to pose a serious fire hazard. This is why you should carefully follow the instructions provided by the manufacturer when using it.

Why Synthetic Oil is Flammable?

Is Synthetic Oil Flammable

It is safe to say that synthetic oil is actually made from a number of hydrocarbons. These hydrocarbons are then combined in one to create a product that is known to have a higher flash point when compared to regular oil.

In this case, the flash point is considered to be the temperature at which a substance ignites and begins to burn. Even though synthetic oil does have a higher flash point than regular oil, it is still flammable.

Does Synthetic Oil Burn in a Fire?

Yes, there is no doubt that synthetic oil burns in a fire, but for this to happen it needs high temperature and heat. Synthetic oil is said to have a high flash point of 400-500 degrees F, which is a lot higher than mineral or conventional oil. As you can see, synthetic oil definitely needs a high temperature to burn in a fire.

Are All Oils Flammable?

Yes, all oils are flammable due to the fact that they contain hydrocarbons. Hydrocarbons are molecules that contain both hydrogen and carbon atoms. At any point these molecules are heated, they can get ignited causing fire to occur.

So, even though synthetic oil is known to have a higher flash point, it’s still considered to be flammable and should be used with caution.

Is All Car Oil Flammable?

The short answer is no. Not all car oils are flammable. There are some car oils on the market that were specifically created to be non-flammable. These oils are usually used in situations where there is a risk of fire such as racing engines.

The thing is that non-flammable oils are said to have a higher flash point than regular oils. What this means is that they can withstand higher temperatures before reaching the point to ignite.

If it’s a case where you are looking for non-flammable car oils, then you should check the product labels and specifications to make sure it meets your requirements. Make sure to also check your car engine oil flash point.

Can You Burn Motor Oil in a Fire Pit?

You can, but it is definitely not a good idea to do so. Once the motor oil actually reaches its flash point, it tends to burn hot. The thing is at this point, you can’t put out the oil fire using only water. This can be extremely dangerous so burning motor oil in a pit fire isn’t the way to go.

Due to its flash point, synthetic oil will not burn well and the heat that is coming from the fire will be too hot for you to be near it. So, think wisely before considering burning motor oil.

How to Deal With An Engine Oil Fire?

If somehow your motor oil does catch fire, you should know exactly how to properly handle the situation. While it is not considered to be flammable, these oils can be easily ignited when that occurs, as it is said to be a Class B fire.

Class B fires are considered as flammable liquids which include gasoline and paraffin. Even though engine oil is not classified as a flammable liquid, however, it is said to be a group in the same category and the reason for this is because of the measurement required to extinguish the flame.

All Class B fires should be put out without water. Let’s not forget that pouring water on an oil fire will only make the situation worse. The flames will become taller and even spread more easily.

To put out a Class B fire, you will need to have a Class B carbon dioxide fire extinguisher. This extinguisher will be able to get the job done with ease. However, If you don’t have an extinguisher in your possession, you will have to contact the fire department immediately.


Though synthetic is considered to be the best motor oil for your vehicle, you should keep in mind that it is considered to be flammable. When you have engine oils in your possession, proper storage is very important so that you can keep them from igniting. Make sure to properly wash away all spills, meaning that you don’t have to ever worry about random fire.
