How To Test For Bad Gasoline? Answers Here!

For the majority of us, it only involves putting gas in the car and driving away. Nowadays, it’s extremely uncommon to purchase bad gas at a gas station.

But it can still happen! That’s why in this article, we’ll share ways how to test for bad gasoline

How To Test For Bad Gasoline

You should start by considering whether it’s feasible that you were the cause of the gasoline’s contamination. 

Whether it was due to letting your vehicle sit, a loose gas cap, or another comparable circumstance.

If the above-mentioned considerations are ruled-out, you can proceed to test your gasoline.

You can follow these steps below: 

Step 1: Smell The Gasoline

The volatile substances in gasoline enable it to burn. 

Gas gradually develops into a sticky, varnish-like substance when these chemicals evaporate, making it less flammable. 

Gasoline starts to smell like strong varnish instead of gasoline when this happens.

Step 2: Visually Inspect The Gasoline

Check the gas for any discoloration or pollutants. Good gas is almost transparent. 

As gas degrades, it becomes darker and eventually takes on a rich amber hue. 

Old gas deposits are frequently found in empty cans and tanks. 

These deposits become loose when fresh gas is supplied, blocking the fuel line, fuel filter, and carburetor.

Additionally, dirt, yard waste, and rust from metal gas cans can get into gasoline and ruin your engines.

Step 3: Look Out For Gas And Water Separation

Gas and water cannot coexist. As a result of weather changes and the ethanol in gas attacking moisture, gas and gas tanks condense. 

Gas is lighter than water, therefore the latter will separate into its own layer and sit below the former.

Smaller amounts of water will be seen rolling around beneath the top layer of gas as bubble-like objects. 

The gasoline tank and numerous other engine components are harmed by water, which also affects how well the engine runs.

If you observe anything unusual with your gasoline as you do the steps above, then your gasoline may be bad

Signs Of Bad Gasoline

Signs Of Bad Gasoline

You may ask yourself: “How do I know if I have bad gasoline?” or “What does bad gas do to a car?

The following are the signs of bad gas in car

Acceleration Issues

Bad gasoline in the internal combustion chamber may cause a chemical delay when you try to accelerate your car. 

This may explain why, despite all of your dry runs when you step on the pedal and check every component before starting, it still doesn’t accelerate right away.

Peculiar Speed Changes

Do you think that the rough rock you feel when you accelerate is the sole sign that your gasoline quality is terrible? Unfortunately, no.

Bad gasoline can also frequently result in unexpected speed increases while driving. 

Damaged Fuel Filter

To prevent dirt and debris from entering the gas tank and mixing with the gasoline, the fuel filter is essential. 

Therefore, if there is anything wrong with this component, it is probably one of the typical signs of bad gasoline.

Naturally, your gasoline cannot function properly if such a crucial component is damaged.

That explains why you should frequently check the fuel filter to see if it is in good condition or not.

Sputtering Or Pinging Noise

Your engine may sputter or ping because bad gas doesn’t burn evenly. While it is idle and as you are moving at a moderate speed, pay attention to your car. 

These noises alone aren’t the smoking gun because they could possibly be the result of a faulty fuel filter.

Engine Break Down

When your car’s engine suddenly shuts off, it’s obvious that something is wrong. 

However, have you ever thought that bad gas would be the most suspect explanation behind such an unsettling occurrence?

In any case, you must.

It cannot provide enough running energy for the engine if a beneficial fuel is not used to operate the internal combustion mechanism.

Car Starting Troubles

When your car starts acting up and you get bad news, it appears like you almost always try to fix the engine and other auto parts first without hesitation.

Another surpris that shouldn’t come as a big surprise, is that bad gas could be the real reason if you’re having trouble getting your manual vehicle to start or even stop.

Thus, without the use of even a single weapon, bad gas in your tank and cylinder can destroy your engine day by day by mixing excessive amounts of water, unnecessary materials, or other filthy substances.

What Causes Gasoline To Go Bad

What Causes Gasoline To Go Bad?

Chemical breakdown and water are the two factors that lead to the degradation of gasoline.

Chemical Breakdown

There are many different chemical components in gasoline. 

Some of these substances are more vaporous and lighter. They react to the oxygen in the air and evaporate when they come into touch with it. 

These substances are responsible for the distinctive odor that most people identify with gas, particularly when they top off their car’s fuel tank.

All that is left of gasoline after the volatile chemicals have evaporated is a thick material that resembles varnish. 

The varnish-like buildup is difficult to burn and can block fuel system parts like carburetors and injectors.

Water In Gasoline

Water getting inside a fuel system is among the worst scenarios that could occur. 

The unpleasant part is that there is no need for a gas tank leak or an open gas cap for water to get inside. 

Condensation may develop on the interior surface of the tank during cold conditions. The water could freeze and obstruct the gas line if you are in a region with severe winters.

Another major contributor to corrosion in the fuel system is water. Rusted components won’t function as intended and may even disintegrate. 

Rust can obstruct the gas line as well, denying the engine of your car the fuel it requires to function correctly.

How To Fix Old Gas In Car

How To Fix Old Gas In Car

It takes some skill to fix faulty gas in a car on your own. 

But if you’re keen and confident in your skills, you can follow these steps for bad gasoline treatment

  • Remove The Tank

The best technique to dispose of gasoline without endangering the car’s engine is in this way. However, it is also the most difficult and labor-intensive.

It might be advisable to pay a mechanic to handle this for you if you are not one yourself.

  • Suck Out The Gas From The Tank

Put a garden hose’s one end inside the gas tank. the other end into a gas can that has been emptied. 

Ensure that the gas can is set lower than the fuel tank. 

From the gas can, take the hose out and carefully suck it on the end.

As soon as you notice that gas is flowing through the hose, put the hose back on the gas can. 

The gas will transfer from the tank to the gas can thanks to gravity.

  • Fill Up The Tank With Dry Fuel

Dry gasoline, which is available in car parts stores, is made to absorb water without impairing engine performance. 

One of the most prevalent pollutants in gasoline is water. It is quickly driven into the engine after being put into a gas tank, where it settles at the bottom. 

Water doesn’t burn, so it makes the engine pop and sputter since it won’t burn.

  • Introduce High-Octane Fuel To The Tank

Slowly add high-octane fuel to the tank. After that, add and mix it with an octane booster. 

Repeat this process two or three more times, adding gas each time the gauge reaches half a tank. 

Using this technique, the bad gas will be diluted by mixing it with good gas, allowing the engine to function normally until the bad gas is gone.

Frequently Asked Questions

How Long Can You Store Gasoline?

The U.S. DoE has established a six-month maximum shelf life for gasoline when kept in proper storage. This does not imply that your gas will spoil in six months. 

The majority of experts concur that fuel can last up to three years if it is kept fresh and free of impurities.

How Do You Properly Store Gas?

An airtight container should be used to store gasoline. Labeling the date the gas was bought and stored is always a good idea. 

Maintain gas in a low-oxygen, cold atmosphere. High heat and humidity might make your stored gas more volatile and raise the risk of fire and explosion. 

Because of this, it is not advisable to have a fuel container that holds more than five gallons of petroleum.

In Closing

There are a variety of ways on how to test for bad gasoline. The simplest way is by using your sense of smell and sight.
