How can one identify Gasoline? What color is gasoline? Can you differentiate when it is either bad or good?
This article will talk about all you need to know about Gasoline.
Natural Gasoline comes in no color. Nonetheless, every grade of gas is dyed using dyes or sulfur. When the gas becomes black or dark brown, there is an issue.

What Color Is Gasoline?
One should be able to know the difference in color, between a bad gas and a good one. Considerable damage can result if your fuel tank has been filled with bad Gasoline.
Just like water, natural Gasoline does not have a color. Although the various grades of gas are dyed using dyes or sulfur, one can tell the difference for a number of octane levels or cars. Black or dark brown gas shows that there is an issue.
Have you ever checked the color of the Gasoline in your vehicle? What is the color? Are you aware of the kind of gas going into your car? Do you know if it matches the one needed for your vehicle?
This article explains things you must be aware of concerning Gasoline, not excluding the meaning, types, and colors.
How to Identify Gasoline
Do you know what gas looks like? If you are in the category of persons who refuel their vehicles at gas stations, you may not have seen what Gasoline looks like. The reason is that it moves from the terminal of a gas station, through a hose, and into your gas tank.
Usually, Gasoline is kept in a place where people can’t have contact with it, and the container is colored, making the color distorted. Even so, you can see the color of Gasoline through your fuel filter in the car.
Some cars own a clear fuel filter; thus, you can keep an eye on the color and condition of the fuel. First, you can open your hood to look at the things in the filter.
Then, when empty as your engine is turned off, you can access the Gasoline by running the car in the parked gear.

Why Is It Important to Know What Color Is Gasoline?
While at the gas station, be rest assured that it is a fresh one that you will get. It is of the best quality for every vehicle, and there is no need to check its color because it is fresh.
Notwithstanding, the case is different when you discuss storing Gasoline. One must monitor regularly and pay keen attention when storing Gasoline.
If you store Gasoline, it is best to make use of it as quickly as you can. Not minding the dye that has been used in your fuel, initially, it will appear transparent-like.
With time, the fuel that is stored will start changing. This is because of the oxidation process. During the oxidation process, oxygen is chemically combined with a substance.
That stored fuel then turns from its original form, to yellow and then to a brownish hue. The initial fresh smell changes to a new sour scent.
When your Gasoline turns orange, kindly discard it. Instead, purchase a new one for your cherished vehicle.
Octane Grade and Gasoline Color
Are you aware that Gasoline color and Octane grade have a connection? They come in three major types:
- A regular 87 octane gasoline is either a green or blue tint.
- Plus/Midgrade 89-90 octane gasoline has a yellow tint.
- The Premium 91-94 octane gasoline has a pink tint.
Nobody can examine the entire gas pump to confirm this fact, but you should know that it is not a criterion.
In the US, the only existing regulation for the color of fuel is tax-exempting fuel used in cooking, heating, and total off-road use. Therefore, your clear filter aids the police officer in checking if you are running on illegal fuel, which is red fuel.
Generally, one is not supposed to see the fuel color; depicting varying octane grades having a different color isn’t necessary. Therefore, it is possible that color matching has stemmed from the colors of those nozzles of a gas station, not the fuel color itself.
How to Recognize Bad Gasoline
Gasoline has a short lifespan of about six months. Regardless, there is a possibility of its lifespan extending by different fuel stabilizers. Note that, as soon as it spoils, avoid using it for any application.
Over time, through evaporation and oxidation, Gasoline degrades. The smell becomes weaker, and you can breathe normally when you are around it. You should remain careful.
Gasoline color also goes through changes. The initial clear color with a bit of yellow hue loses clarity, and while degradation continues, you will see it darkening. As its color becomes brown and dark red, you will see sedimentation at its bottom.
One should dispose of bad Gasoline at the recycling facility. Since it has lost a lot of energy, it is no longer fit for internal combustion and can contaminate your injectors, fuel line, fuel tank, and various components.
How to Identify Gasoline by Its Smell
Gasoline vapor is very toxic for humans, and when exposed to it, breathing it deeply can result in lightheadedness and headache.
Benzene is what causes gas to smell, and it is unique. If you notice a smell while refueling at a gas station, you can recognize it anywhere. It has a strong scent that is reminiscent of alcohol, but the irritating difference is that it makes it difficult for one to breathe.
Instead of deciphering the things in a canister by looking at the liquid color, the smell can tell you that it is Gasoline immediately after you remove the cap. Being aware of the smell of Gasoline is very useful; for instance, if Gasoline mixes with your engine oil.
How to Remove Oxidized Gasoline
It is best to ask for the assistance of a professional and seek help, instead of relying on your basic knowledge. Although if the mentioned situation doesn’t give room to it, you can follow stipulated instructions on ways of removing bad fuel by yourself.
If one sees that Gasoline has been oxidized, it is good to take it away from the fuel tank.
When your fuel tank is filled with expired gas, it will require more time to be done with emptying it, because one needs about two minutes for him/her to siphon out a gallon of gas. Thus, you should set out time for pumping out the bad fuel.
In addition, make sure to be in an area that is properly ventilated, before you begin draining the fuel tank because of harmful gasoline vapors.
Most importantly, you should make available the siphon hand pump. It is harmful to swallow or inhale Gasoline; hence, you should use the siphon hand pump.
It is a small tube for pumping out gas from a fuel tank. It should be ⅜ inch to 1 inch thick and 6 feet long. Note that as the hose is thicker, the pump becomes longer.
You also need a fuel storage can for disposing of and storing oxidizing gas. If you’re making use of a hand pump, you will be able to fill the siphon hose inside your fuel tank.
As you reach your fuel tank, you are to feed another hose inside your fuel storage can and then keep pumping out gas, till your fuel tank becomes empty.
As bad gas has been siphoned from your fuel tank, you are mandated to take it away to a site approved by the government. Never throw gas in lakes, drains, trash cans, etc.
Ensure you call the local waste personnel, to make sure you use the correct disposal site.
Storing Gasoline in Colored Gas Cans
The reason gasoline is set to be deduced by its color, to avoid the dangers of wrong application, applies to its means of storage. Different gas types are stored in colored gas cans. Having this knowledge saves time in finding out the gas contained, in a particular colored gas can.
Examples of colored gas cans include:
Green Cans: These are used for storing oils.
Red Cans: Red cans are seen as color-coded for storing flammable liquids; it includes only Gasoline.
Yellow Cans: Yellow cans are only used in storing diesel fluids.
What Is Gasoline’s Lifespan?
It does not last for long. Its lifespan is between three to six months. As it approaches its expiration, the gas becomes unusable and oxidizes.
Unluckily, fuel types that are of higher grade do not have the advantage of a longer life span, than regular Gasoline.
Although, we have ways of extending a gasoline’s lifespan. Some fuel stabilizers can be bought, to slow the time gas takes to oxidize. The trending fuel stabilizer brands are Marvel, Lucas, Seafoam, and STA-BIL.
Additives and fuel stabilizers are better used in a new gas for offsetting oxidation effects, yet they will not have much effect on oxidized Gasoline.
Using a fuel stabilizer keeps Gasoline fresh, for about one to three years.
If in the fuel tank you have old gas, there is an option of diluting it with new Gasoline. The car’s combustion ability allows one to use old Gasoline.
In this process, ensure you call a professional to know if there is a need, for adding fuel additives to your fuel tank.
