New car out of the factory，It is possible that no one has been asked for three or five years。Therefore, the oil in the new car fuel tank，Good stability，Good startup performance，Can be opened for a few years，This is the first installation oil。

Preliminary Oil due to the multiple process procedures，High production cost。Therefore, although the shelf life is long，Stability of traits，Not easy to deteriorate，But its economy is poor，No sale on the market。So ordinary gasoline added by our owner，Is there a shelf life? Will it deteriorate after a long time?

The answer is:seabet app

Because the density of gasoline is less than diesel、Blooding point is lower than diesel、Volatility is greater than diesel，So the shelf life will also be shorter than diesel，The shelf life of gasoline under normal circumstances is 3 months.

But the gasoline does not have deterioration problems。The structure of gasoline is a complex organic chemical chain，99%or more is carbon element，It will only volatilize and occur in some chemical changes when they are in contact with air。SoSeal gasoline with metal container or glass container can be kept permanently，Seal with plastic containers，Storage for up to 2 to 5 years。

diesel shelf life is generally 12 months or even a few years，There is also a saying that diesel has no shelf life，Just when it is placed for a long time, there will be insufficient combustion。

From the perspective of inspection and retention，General diesel sampling time is 3 months，DescriptionDiesel can ensure product quality(compliance with the national bid regulations).

Decrease in deleane value、Burning substance volatilization、Oxidation status, etc. are all factors that directly affect the shelf life of gasoline。

Diesel has been stored for a long time, and the combustion rate will slowly decrease.If there are more substances in oil products，Easy Volatility Murants Ex many，It is easy to deteriorate。For example, catalytic cracking diesel does not be treated with hydrogenation，The color changes in two days。Therefore, diesel also needs to be sealed and saved。

If you refuel at a regular large gas station，That will definitely not add to the expired oil。Because China's refined oil demand is very large，Refined oil directly enter the market，Generally, it will not be stored in the sales process for more than 3 months。

TakePetroChinaLet's talk about，A urban gas station，At least twice a day a day，About 20 tons of oil。This is calculated，20 tons of oil，Time to stay in the oil tank，It's only half a day。

and in the oil depot，Oil storage has a set of strict crafts，Prevent superfinality。and the oil products enter the warehouse、Exit the warehouse must pass the test，Qualification can release。That's it，refined oil flowing here continuously，Entry is sealing storage，Disposal to each gas station，Then enter the owner's fuel tank，Turn into driving power。

You can see，refined oil from refining to consumption，The overall time is not long，And most of them are in a state of sealed preservation。So，Oil at large regular gas stations，It is impossible to have problems with expired deterioration。

but，Do not rule out some illegal gas stations，Will sell expired gasoline and diesel，or use expired oil products to reconcile and sell。They seduce car owners seabet ioat a low price，So we must have multiple hearts，Delivery for gas stations is common，But the unreasonable low price，Be careful。

Look at it.The normal color of gasoline is pale yellow or pale yellow green，diesel is light yellow or transparent color。The color is too shallow，May add additives，Add stability。The color is too darker，It is likely to be the cause of deterioration。

Second news.Gasoline contains aromatic hydrocarbons，Some people even smell incense。and some label gasoline adds mtbe (methyl uncle butyl ane ether，Used to improve the deleane value)，There will be a bit of sour flavor，butAt leastNo discomfort to smell。If smelling stink，There must be problems。

Three touch.Touching astringency with electricity and diesel，Micro Cool，Because it is easy to volatilize。If you can not volatilize it for a minute or two in your hand，Be careful to mix in what is mixed。And the gasoline is relatively refreshing to the touch，Diesel feels more smooth to touch。

Si Shao.This method is mainly used for identification between gasoline and diesel。Shaking oil，The foam produced by gasoline can generally disappear quickly，Diesel disappears a bit slowly。

The direct performance of expired gasoline and diesel is insufficient power，Then the engine operation is rough，A long time will cause obstruction、Carbon accumulation and other conditions occur，Direct impact on the engine。

It was found that expired gasoline and diesel，If there are not many oil leftover products left in the fuel foam，Then go to the gas station and add fresh oil，The problem is not big。

If there is a large amount of expired oil in the fuel tank，It is recommended to contact 4S shop，Expired oil，Cleaning fuel tank oil road，Replenish fresh oil。

In case of halfway anchor，The car should be turned off immediately，Don't start again，Drag seabet loginthe car into a professional maintenance plant，Let the professionals maintain，Minimize the damage to the minimum。

In short，If the oil products are improper，It will deteriorate for a long time。So if your car loves for more than 3 months, it will not start，Discover insufficient power when starting again，So it may be caused by the deterioration of oil。Similarly，If your car plan is placed for a long time，Then leave a small amount of oil in the fuel tank。
