How long is the shelf life of gasoline and how long is the shelf life of gasoline

The shelf life of gasoline in the tank of a car is three months.

Because gasoline is less dense than diesel, the ignition point is lower than diesel, and the volatility is greater than diesel, the shelf life will be shorter than diesel, and the shelf life of gasoline is 3 months under normal circumstances.

However, there is no deterioration of gasoline in sealed conditions. The structure of gasoline is a complex organic chemical chain, more than 99% of which is carbon, which only volatilizes and undergoes some chemical changes when it comes into contact with air. Therefore, gasoline can be stored permanently in metal containers or glass containers, and sealed in plastic containers for up to 2 to 5 years.

The shelf life of diesel is generally about 12 months or even a few years, and there is also a saying that diesel has no shelf life, but it will be burned inadequately after being placed for a long time. Diesel fuel is stored for a long time, and the combustion rate will slowly decrease. If there are many unstable substances and volatile components in the oil, it is easy to deteriorate.

For example, the color of FCC diesel does not go through hydrotreating, and it changes color in two days. Therefore, diesel fuel also needs to be sealed and stored.

Characteristics: 1. Anti-explosion.

The property that measures whether a fuel is prone to knocking is called knock resistance, and gasoline knock resistance is expressed by the octane number (RON). The higher the octane number of gasoline, the better the knock resistance.

For the same hydrocarbons, the carbon number is small, the knock resistance is good, and the octane number is high. For all hydrocarbons with the same carbon number, the octane number from large to small is aromatic hydrocarbons, isoparaffins and isomeric olefins, n-olefins and naphthenic alkanes. For different straight-run fractions of the same **, the lighter the fraction, the higher the octane number; Fractions with the same boiling range are different, with different chemical compositions and different octane numbers.

2. Corrosive.

Gasoline corrosiveness is related to sulfur and sulfur-containing compounds, organic acids, water-soluble acids or bases.

3. Cleanability.

Gasoline often contains mechanical impurities and moisture. Mechanical impurities can cause serious consequences such as oil circuit blockage and increased wear. Water mixed into gasoline will accelerate the oxidation of gasoline, and form an acidic aqueous solution with low-water molecular organic acids in gasoline to corrode metals, and it is easy to freeze and form ice particles at low temperatures to block the oil circuit.

Therefore, the mixing of mechanical impurities and water should be strictly controlled in vehicle gasoline.

Gasoline can be stored for 2-5 years, and if it is sealed well, it can be stored for a longer time. Isolated from the air and sealed in metal or glass containers, gasoline has a long shelf life. There is no air going in, and there is little chance of air running into the tank, so it has a very long shelf life and almost no spoilage.

Gasoline should be stored with iron, fiberglass, and other things, and must be sealed tightly and not plastic, which is easy to produce static electricity and is very dangerous. It's good to put it in a cool place, it's best not to store too much gasoline, gasoline will also deteriorate after a long time, keeping gasoline fresh is good for the engine.

How long 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 has a shelf life of about two years, and if it goes bad, it has a different smell than usual. There is also ethanol gasoline that has a shelf life of only one month.

Generally, it takes 1-2 years, but the shelf life is shorter after adding ethanol.

It can be stored for one year without volatilization, but it is not recommended to store it for a long time, it is very dangerous, and it must be stored in an iron container.

Hello dear, the shelf life of ordinary gasoline is generally about 3 to 5 months. First, if the gasoline is stored for a particularly long time, the relevant chemical properties will change, and then the gasoline will deteriorate, and second, the vehicle can be started at that time, but the relevant gasoline burns abnormally, which will cause the fault lamp to light up. Third, long-term storage of gasoline is also easy to cause the vehicle to speed up the weakness, and the acceleration ridge and talk frustration are easy to produce carbon deposits.

All the best!Fortune is on the head!

Summary. Hello dear, the shelf life of gasoline is about three months. The active ingredient of gasoline is volatile.

If the gasoline is stored for too long, the combustible part will definitely be reduced. After the expiration date, the oil changes. Car owners can identify the quality of oil from three aspects: color, smell and feel.

The English name of gasoline is gasoline (United States) gasoline (United Kingdom), transparent and flammable in appearance, and the distillation range is 30 -220. Its main components are C5 C12 aliphatic hydrocarbons and naphthenic hydrocarbons, as well as a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance), and is divided into 89, 90, 92 and 93 according to the octane number.

Different gasoline components, such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components obtained from petroleum refining, are refined and blended with high-octane components, mainly used as fuels for automobile ignition internal combustion engines. The important properties of gasoline are evaporation, stability, knock resistance, corrosiveness, and cleanliness. Evaporation, gasoline must be rapidly vaporized in the engine cylinder to form a homogeneous combustible mixture with the air body, which is mainly determined by the evaporation of gasoline itself, and the main indicators reflecting evaporation are distillation range and saturated vapor pressure.

Stability, the ability of gasoline to resist oxidation at room temperature and liquid phase is called the oxidation stability of gasoline, referred to as stability. The indicators to evaluate the stability of gasoline are divided into iodine value, actual gum and induction period. Anti-knock, the property that measures whether the fuel is prone to detonation is called anti-detonation, and gasoline anti-detonation is expressed by octane number (RON).

The higher the octane number of gasoline, the better the anti-knock performance.

For similar hydrocarbons, the carbon number is small, the anti-knock performance is good, and the octane number is high. ::n-alkanes have different straight-run fractions of the same **, the lighter the fraction, the higher the octane number; Different** fractions with the same boiling range have different chemical compositions and octane numbers. Corrosiveness, gasoline corrosiveness is related to sulfur and sulfur-containing compounds, organic acids, water-soluble acids or bases.

When cleaning, gasoline often contains mechanical impurities and moisture, which can cause serious consequences such as oil clogging and increased wear. When water is mixed into gasoline, it will accelerate the oxidation of gasoline, form an acidic aqueous solution with the organic acids of low water molecules in gasoline, and corrode metals. At low temperatures, it is easy to freeze and form ice particles, blocking the oil circuit.

Therefore, the mixing of mechanical impurities and moisture in motor gasoline should be strictly controlled.

Hello dear! The shelf life of gasoline is basically about three to six months, and it is recommended that it should be used up in six months, so as to give full play to the best power performance of the oil. If the car is parked for too long, the alcohol in the gasoline will volatilize a small amount, and the gasoline may be stratified, which will affect the normal operation of the car engine.

Reasons why gasoline expires:1The light components of gasoline are volatile and know land; The reason why gasoline can be used as a fuel for automobile engines is that gasoline volatiles form a stable mixture with air components, and the light components of gasoline are volatilized without being used for a long time, and the concentration of recombinant components gradually increases, and at this time, the volatiles of gasoline are difficult to form stable combustibles with air and deteriorate.

2.gasoline oxygen wheel decontamination; The hydrocarbons in gasoline are prone to repulsive chemical reactions with oxygen, and after this change, gasoline will emit an acidic odor, and the color will become darker, producing colloidal particles.

Summary. Pro, gasoline gasoline has a shorter shelf life than diesel, and the shelf life is 3 months under normal circumstances. However, gasoline is stored in sealed conditions without deterioration, its structure is a complex organic chemical chain, more than 99 is carbon element, when in contact with air will volatilize and some chemical changes, sealed gasoline in metal containers or glass containers can be stored permanently.

Seal in a plastic container and store for up to 2-5 years. In diesel-diesel refining, the oil product is composed of a mixture of hydrocarbons, and the physical properties are located between gasoline and heavy oil. At 20°C, diesel has a shelf life of at least 12 months.

Why should there be a shelf life for gasoline? Gasoline is a flammable liquid Fengdan, after a certain period of preservation, the aromatic hydrocarbons and other substances in the gasoline will gradually evaporate, so that the index of gasoline oil changes, affecting the combustion performance of gasoline, the poor combustion performance of gasoline will affect the normal silver gear of the car to disturb the car, and even the first catastrophic accident may occur. Therefore, in order to ensure the quality of gasoline and ensure the safe driving of automobiles, it is stipulated that gasoline has a shelf life requirement.

Summary. Precautions: If gasoline is stored in high temperatures, humidity, direct sunlight, or air for a long time, it may accelerate deterioration.

Spoiled gasoline may cause problems such as unstable engine operation, difficulty starting, increased fuel consumption, and even damage to the engine. Therefore, it is advisable to use fresh gasoline as timely as possible, while taking care to maintain its quality when storing. If you don't use gasoline for a long time, you can consider adding a gasoline stabilizer to extend its shelf life.

Summary. If you use ethanol gasoline in the region, the shelf life of ethanol gasoline is about 1 month. If the car is parked for too long, the alcohol in the gasoline will volatilize in small amounts, and the gasoline will have a stratification phenomenon, which may affect the normal operation of the car engine.

Hello dear, I am glad to answer for you, after inquiry, generally speaking, the shelf life of ordinary gasoline is normally 3 months.

Ordinary gasoline does not contain ethanol, the fuel tank of the car is relatively sealed, and the gasoline has good stability in a closed environment. However, there is still oxygen in the fuel tank, and the contact between gasoline and oxygen will undergo an oxygen Zen reaction, which is at risk of deterioration. The shelf life of regular gasoline is normally 3 months.

If ethanol gasoline is used in the region, the shelf life of ethanol gasoline is about 1 month. If the car is parked for too long, the alcohol in the gasoline will volatilize and collapse in small amounts, and the gasoline will have stratification, which may affect the normal operation of the car engine.
