Does gasoline expire and can you still use it if it expires

All products have an expiration date, including gasoline, of course.

Factors such as storage conditions, containers, environmental changes, etc., can all affect the quality of gasoline.

The length of gasoline storage time may affect the octane number, actual gum, organic moisture, metal content and other indicators of the oil (and sealing is not equal to avoiding light, some antiknock agents may decompose in light, if unfortunately encounter blended gasoline or methyl ethanol gasoline, it is necessary to speed up the turnover, and it must not be stored for a long time).

The maximum length of time gasoline can be stored in the drum is also related to two factors.

1. Volatilization. It is directly related to the sealing effect.

2. The damage of the container is mainly the corrosion of the iron drum here, because the gasoline contains a certain acidity, so it has a certain corrosive effect.

Gasoline, diesel and other fuels have the characteristics of thermal expansion and cold contraction, gasoline, diesel is usually packed in a sealed oil drum for transportation or storage, in order to prevent the temperature from rising volume expansion, causing danger, so when filling oil into the oil drum, it can not be filled, but to leave some gaps.

For anti-static safety, do not use containers made of plastic and other insulating materials for storage (such as plastic buckets) to prevent liquid shaking, friction, and static electricity during dumping. It is best to use metal barrels for storage, so that they are tightly sealed, stored in a cool and ventilated place (to prevent volatilization and flammable and explosive mixed gases), and when opening, you must pay attention to whether there is no pressure holding inside and whether the barrel is deformed (to prevent damage caused by pressure spraying).

Do you say that something that is tens of thousands of years old underground has a production date?

If you don't drive for a long time, will gasoline expire? Does expired gasoline have an effect on cars.

It is better not to continue using the gasoline after it has expired.

The shelf life of ethanol cars will be shorter than that of regular gasoline, about one and a half months. Gasoline can not be used for a long time, because gasoline is stored for too long, it will be seriously oxidized, and colloidal will be generated, which can make the engine valve sticky, not tightly closed, and decompose at high temperature to generate carbon deposits on the oil circuit and other components, resulting in poor engine work.

Although gasoline has the same shelf life as food, the main components of gasoline are carbon and hydrogen, in which diolefins will oxidize in contact with air, and the freshness period of gasoline is within two months, during which time can give full play to the best effect of gasoline, so that the engine burns more fully, and the quality will gradually decline after two months.

The duration of the oil

As an organic solution, gasoline can also be used as an extractant, and is currently the most widely used as an extractant for the domestic soybean oil mainstream production technology code lack of letter technology, leaching oil technology. Although the gasoline filter element will be automatically filtered, it will cause a serious oxidation reaction after long-term storage, which will reduce its quality, and the generated gum and carbon deposits will adhere to the cylinder wall, which will lead to a decrease in engine work efficiency, or block the valve and cause problems such as cylinder bursting.

If gasoline is placed through a container such as metal or glass, the shelf life will be greatly extended due to the airtightness of the material, but at present, the plastic fuel tank is commonly used in the vehicle wheel, and its sealing can not completely isolate the air compared to the above containers, and the use of metal material may increase the weight of the car or the manufacturing cost.

Gasoline additives should not be used after they have expired. Expired fuel additives are counterproductive, not only will they not reduce fuel consumption, but they will also damage the engine and reduce the life of the engine. So when choosing fuel additives first.

It depends on whether the product is within the expiration date.

secondly, it depends on whether the product has the quality certification of the national authority; Again, it depends on whether the enterprise has passed the quality management system certification.

Finally, we must look for formal channels.

A good choice of fuel additives can not only reduce fuel consumption, but also maintain the engine and remove carbon deposits.

environmental protection and other effects. In fact, the use of fuel additives can achieve the purpose of fuel saving, which is ostensibly to save money for car owners, but actually contributes to environmental protection.

Can expired gasoline additives work? This must not be used, expired things must be thrown away, gasoline can not be used, and it is prone to fire**.

Expired gasoline additives will not only not reduce carbon deposits, but will also damage the engine and reduce the life of the engine. It is better not to add additives indiscriminately, including engine oil additives.

No, it has expired, which means that the effect has been lost and is useless.

Fuel additives generally have a shelf life Now there are two kinds of popular additives on the market: solid and liquid, the advertised shelf life of liquid is 2-6 years, and the shelf life of solid state ranges from 3-10 years. However, from the perspective of the additives themselves, additives must have their shelf life, because the liquid state is chemical, affected by temperature, light, pressure, humidity, oxygen and other chemicals, its chemical properties will definitely change slowly.

Gasoline expires.

Theoretically speaking, gasoline has a shelf life, because basically more than 99% of cars are carbon and hydrogen, and after contact with air, partial oxidation reaction will occur, and then colloids will be produced, so gasoline will also deteriorate. We don't have to worry too much, though. The sealing performance of the automobile fuel tank is very good, and the probability of air entering is very small, so the shelf life of gasoline will be extended, and it can be used normally after a few months of storage.

However, there are now many types of gasoline. If you add ethanol gasoline, pay attention. Because ethanol gasoline is a mixture of gasoline and ethanol, it is simply a blend of 90% regular gasoline and 10% fuel ethanol.

Basically, the shelf life of a tank of ethanol gasoline is only 30 days. Once this number is exceeded, a small amount of alcohol in the gasoline will evaporate, and the gasoline will stratify, which will inevitably affect the production efficiency of the engine.

Therefore, it is not recommended for everyone to use gasoline stratification, because not only can it not volatilize the maximum performance, but the most obvious manifestation of direct use is insufficient power, and then the engine runs roughly, which will also cause insufficient fuel combustion, carbon deposition, fuel injector blockage, unstable idle and other phenomena. This will directly affect the efficiency of the engine, and if it is used for a long time, the engine may be damaged.

No matter how good the gasoline is, the quality will deteriorate as the storage time increases. Therefore, if you want to avoid the spoilage of gasoline, it is best to use up a tank of oil in 3 months.

Gasoline is something that expires.

However, there is no deterioration problem in the sealing condition of gasoline, its structure is a complex organic chemical chain, more than 99 is carbon element, volatilization and some chemical changes will occur when in contact with air, gasoline can be stored permanently sealed in metal containers or glass containers. Seal in a plastic container and store for up to 2-5 years.

If expired oil is used, its direct manifestation is insufficient power, resulting in rough engine operation, and over time, it will cause blockage, carbon deposition and other problems, which will have a direct impact on the engine.

The role of gasoline:

Gasoline is one of the most widely used light petroleum products and is an important fuel for engines.

According to the manufacturing process, gasoline components can be divided into straight-run gasoline, hot-cracked gasoline (coking gasoline), catalytic cracking gasoline, catalytic reforming gasoline, superimposed gasoline, hydrocracking gasoline, alkylated gasoline, and synthetic gasoline, among others.

Gasoline products can be divided into three categories: aviation gasoline, vehicle gasoline, and solvent gasoline according to their use. The first two are mainly used as fuel for gasoline engines, and are widely used in automobiles, motorcycles, speedboats, helicopters, agricultural and forestry aircraft, etc.
