How Long Can Gasoline Be Stored?
Unlike milk, gasoline does not have an expiry date. As a result, predicting how long the gasoline will last might be tricky.
Nonetheless, gasoline degrades fast and will inevitably diminish its efficiency. But how quickly and for how long can you keep it in the petrol tank of a car or in a container? Well, wholesale gasoline suppliers has a sound take in this context.
We’ll look at how long gasoline lasts in this post. We also look for techniques to keep gas fresher for extended periods of time. Let’s get right to work!
Exxon Mobil estimates that gas in a sealed container will survive for around six months, give or take a month or two. It begins to oxidized, deteriorated, and lose combustibility when left unused.
In addition, the gasoline suppliers recommends that gasoline be utilized in a vehicle within a month of being pumped. In the fuel tank, however, most fuel will last three to five months. In ideal conditions, diesel fuel should last between six and twelve months in a diesel engine.
Finding out how old the gas is when you pump it is the most difficult task. It may have sat there for a month at the gas station. You also have no way of knowing how long it sat in storage at the refinery before being delivered to the gas station.
The Shelf Life of Gasoline
The amount of time that gasoline will be usable in your gas tank is determined by the type of fuel. Regular gasoline has a three- to six-month shelf life, whereas diesel can last up to a year before degrading. Because of oxidation and evaporation, organic-based ethanol can lose its combustibility in as little as three months.
It might be difficult to keep track of the age of the fuel in your tank. It begins its existence at a refinery, where it may have been held indefinitely before being transferred. This time frame might range from a few days to a few weeks.
Final Thoughts
The expiry date of your fuel is not indicated on your gas station receipt by a line of text. Because it doesn’t function that way, it’s nearly difficult to give an accurate figure.
FAQs About the Shelf Life of Gasoline
1. What is the shelf life of gasoline?
Gasoline typically has a shelf life of:
- 3 to 6 months for regular gasoline, depending on its storage conditions.
- Up to 12 months for diesel under optimal conditions.
Ethanol-blended fuels degrade faster due to oxidation and water absorption, often within three months.
2. How long does gas last in a container?
Gasoline stored in a sealed, approved container can last:
- 3 to 6 months for regular gasoline.
- 1 to 2 years if treated with a fuel stabilizer and stored in a cool, dry place.
Exposure to heat, air, and light can accelerate the degradation process.
3. How long will gasoline last in a car’s fuel tank?
Gasoline typically lasts:
- 3 to 5 months in a car’s fuel tank under normal conditions.
- Ethanol-blended fuels may lose efficiency sooner, especially in humid climates, as they absorb moisture.
4. Can you extend the shelf life of gasoline?
Yes, using a fuel stabilizer can slow down oxidation and maintain gasoline’s combustibility for up to 12 months. Store gasoline in an airtight container, away from sunlight and extreme temperatures, to prolong its shelf life.
5. How can you tell if gasoline has gone bad?
Signs of degraded gasoline include:
- A sour or varnish-like smell.
- Darker or murky appearance.
- Reduced engine performance, such as sputtering or difficulty starting the engine.
6. Is it safe to use old gasoline?
Using old gasoline can harm your engine. If the fuel shows no signs of degradation, you can mix it with fresh gasoline to restore usability, but it’s best to consult a professional.
7. Does the type of container affect gasoline’s shelf life?
Yes, gasoline lasts longer in airtight, approved containers specifically designed for fuel storage. Avoid using plastic or unsealed containers, as they can let air and moisture in, speeding up degradation.
8. How does ethanol affect gasoline’s shelf life?
Ethanol in gasoline absorbs water from the environment, leading to phase separation and quicker degradation, often within three months.
Final Thoughts
Understanding the shelf life of gasoline is crucial for maintaining efficiency and avoiding engine damage. While gasoline doesn’t come with an expiration date, following proper storage techniques and using stabilizers can help prolong its usability.
