What is the relationship between the food you eat and the gasoline in your car? Not quite the million-dollar question you were expecting, but a valid illustration.
The gasoline you put in your car functions the same way as the food you eat because they are both sources of energy. Without gasoline in a gasoline-powered vehicle, your car cannot start. Most of all, it won’t be able to serve the purpose you purchased it for.
Have you considered what the gasoline in your car looks like? What color is the gasoline? Do you know the type of gas that goes into your car and if it is the right type for your car?
This article will explain all you need to know about gasoline, including the types, colors, and what they mean.
What color Is Gasoline?
Gasoline is a fluid-like petroleum substance that is derived from crude oil after it has undergone a refining process. The process of refining crude oil to produce gasoline, among other petroleum products, is known as fractional distillation.
Gasoline is used as fuel to power engines by combusting within the chambers of the engine. This combustion process is necessary to convert the stored energy in the gasoline into kinetic energy, which makes your car move.
Types of Gasoline
There are three classes of gasoline. This classification is based on the ‘ease of combustion of the gasoline’ known as its octane rating. The easier it is for gasoline to combust (ignite and burn) under compression, the lower the octane rating. Gasoline with a higher octane rating will not ignite as easily as gasoline with a lower octane rating.
- Regular Gasoline: Gasoline that falls into this category has an octane rating of 87 and combusts easily under compression. Also, there is a tendency for gasoline to combust prematurely.
- Mid-grade Gasoline: Gasoline within the mid-range category has an octane rating of 89 and can withstand more compression than regular gasoline. This reduces the tendency for this category of gasoline to combust prematurely.
- Premium Gasoline: Premium gasoline has an octane rating of 90 and above and can withstand more pressure because of compression before igniting. Also, the chances of premature combustion are reduced.
Color of Gasoline
The color of gasoline when it is extracted from the refining of crude oil is transparent. The color(s) you see gasoline having is because it has been dyed. This is a common trend among many manufacturers of petroleum products.
You will be introduced to the different colors of gasoline based on their types or grade.
This section will provide answers to questions you may have, such as;
- What color is premium gasoline?
- What color is gasoline for cars?
- What color is unleaded gasoline?
Regular Gasoline: Regular gasoline is also referred to as unleaded gasoline. The addition of green dye to the regular gasoline you use in your car handles the gasoline’s green color.
Mid-grade Gasoline: Yellow dye added to mid-grade gasoline gives the gas its distinct yellow color.
Premium Gasoline: This type of gasoline is dyed pink.
Storing Gasoline In Colored Gas Cans
The idea of differentiating gasoline using colors to prevent mishaps of application also applies to storing them. Colored gas cans are used to store different gas types. This knowledge will save you time trying to find out which gas is contained in which colored gas can.
Examples of colored gas cans include;
- Green Cans: Green color cans are primarily used to store oils
- Red Cans: These cans are color-coded to store flammable liquids, including gasoline only.
- Yellow Cans: These colored cans are used to store diesel fluids only.
Frequently Asked Questions(FAQs)
Q: What should gas look like?
Naturally, gasoline obtained from refined crude oil should appear transparent like water. Different grades of gas are dyed distinct colors to help differentiate them from one another based on their uses and octane rating.
Q: What is used to color gasoline?
Dyes are responsible for the distinct colors you see gasoline has. The addition of dyes has become an accepted method of telling different types of gasoline. Each type of gas has a specific color of dye added to it for easy identification.
Q: What gas is colored red?
Red gas, or red diesel, has been dyed red to help differentiate it from green diesel. Red diesel is intended to be used as heating oil or used off-road. Unlike gasoline or standard diesel, they exempted red gas from federal taxation.
Q: Is gasoline dyed?
Yes, gasoline is dyed and for good reason, too. If gasoline is not dyed, it will have a water-like appearance. That is, it will be clear. Also, gasoline is dyed to help you differentiate the types of gasoline and their applications.
Q: Is mixed gas blue?
What color is gasoline mixed with oil? It has a blue color. The blue color of gas is derived from the 2-stroke oil that is mixed with it. This helps separate it from the type of gas a 4-stroke engine will use. The type of gas used by a 4-stroke engine is not mixed.
Q: What does expire gasoline look like?
From the appearance and smell of the gas, you can tell if the gas is bad or expired. Bad or expired gasoline has a darker color and a sour-like smell unlike the transparent look and strong smell of fresh gas.
Q: Why does gas turn orange?
The presence of rust or rust residue in your tank can make your gas turn orange. When pumping fresh gas into your car, the rust residue mixes with the gas to give it an orange tint.
Q: Is brown gas bad?
When the color of your gas appears a darker shade than normal, this could be dangerous to your car engine. Most times, it occurs because the gas has been oxidized. The gas in your car becomes oxidized if your car has been stationary for a month or longer without driving.
Q: What gas glows pink?
The pink color of gasoline comes from the pink dye additive in your gas. The dye is used to differentiate premium gasoline from both regular and Mid-grade gasoline, which have lower octane ratings.
Final Words
Knowing what color is gasoline can save you from causing serious damage to your car. There are three different types/grades of gasoline, with each type a distinct color from the others. This gasoline is color-coded to make it easy to identify the right gasoline you need.
In addition, knowing gas cans’ color codes will enable you to select the can containing the liquid that you need. You can never be too careful when selecting the right gasoline.
