If you’ve interacted with vehicles, you may have noticed that most of them use gasoline. Even if you haven’t, chances are you’ve heard the word gasoline mentioned here and there.

Although many people are familiar with the term gasoline, most do not know what exactly it is.

A large part of these people do not know its properties either, for example, the color of gasoline. Well, let’s talk more about gasoline types, colors, and much more.

What is gasoline?

Gasoline is a type of liquid that is used in the internal combustion of many engines. Combustion, in simple terms, is the burning of a substance, in this case, gasoline.

It is this process that causes movement in machines / vehicles. Gasoline is basically the fuel that makes engines run.

Gasoline is generally extracted from crude oil by fractional distillation. This process is commonly done in oil refineries. One of the reasons for this is due to the complexity of the distillation process.

Types of gasoline

gasoline type

Gasoline is divided into three main types based on its octane rating. Octane is the amount of compression a gas can withstand before combustion.

Therefore, the lower the rating, the more likely combustion will occur at the wrong time.

Let’s look at this phenomenon by examining these three types of gasoline;

87 octane (normal)

Regular gasoline is gasoline whose octane number is 87. Here, the probability of combustion occurring at the wrong time is high.

89 octane (medium grade)

This type of gasoline has a rating of 89. Here the octane is in the middle ranges. Basically, it is neither tall nor short.

90+ Octane Rating (Premium)

Here, the octane number is usually 90 or higher. Due to its high octane number, combustion is less likely to occur at the wrong time.

Color of gasoline

The original color of gasoline is transparent. Basically, once the gasoline is drained, all you will see is a clear, transparent liquid.

Why do different grades of gasoline have different colors?

As stated above, gasoline is clear / colorless. So the question arises, why do we have different kinds of colored gasoline? The reason for this is simple.

Many petroleum manufacturers often add dyes to this clear liquid. This helps them differentiate between the different grades of gasoline. With this, mishaps in some applications are easily avoided.

Another reason is that it makes it easier for people to test for water contamination. Basically the water test would be a challenge if all types seemed clear.

The reason for this is that both gasoline and water would be the same. Therefore, the addition of dyes makes the water stand out when it is in a separation cylinder.

Colors according to the types of gasoline

Different colors of dye are used in each of the types of gasoline. This makes it easier to tell them apart. Here are the colors of each type of gasoline.

  1. Regular – normal gasoline is usually greenish or slightly bluish in color.
  2. Half grade – Medium grade gasoline is usually yellowish in color.
  3. Premium – Premium, the one with high octane ratings, is usually pink.

Does the color of the gasoline matter?

what color is gasoline

The existence of different colored types begs the question, does color really matter? To answer this question, we need to look at this from two different perspectives.

One of these perspectives is when you are pumping fresh gasoline from the gas station. Here, the color of the gasoline has no effect as long as it is fresh.

The other scenario is when you are storing gasoline. Here you have to pay close attention to gasoline as time goes by.

When storing gasoline, regardless of the dye used, it will be transparent in nature. Now this is the best type of gasoline to use.

Over time, the color of the gasoline will change. This is usually caused by oxidation. Oxidation is the process by which a substance (gasoline in this case) combines with oxygen.

As gasoline ages, it will change from its original color to a brown color.

Color isn’t the only thing that changes when you store gasoline over a period of time. As gasoline ages, you will notice that the smell changes as well.

Old gasoline has a sour smell unlike the strong smell it normally has when fresh.

So why is it important …
