What are the disadvantages of adding ethanol gasoline and pure gasoline to cars sometimes?

Sometimes ethanol gasoline is added, and sometimes pure gasoline is added, which has little effect on the car.

Ethanol is a kind of renewable energy, which is made from sorghum, corn and potatoes by fermentation. It does not affect the driving performance of the car, and also reduces the emission of harmful gases.

As a new clean fuel, ethanol gasoline is the development focus of renewable energy in the world at present, which is in line with China's energy substitution strategy and the development direction of renewable energy. The technology is mature, safe and reliable, which is completely applicable to China and has good economic and social benefits.

Ethanol gasoline is a mixture, not a new compound. Adding proper amount of ethanol into gasoline as automobile fuel can save petroleum resources, reduce air pollution caused by automobile exhaust and promote agricultural production. So it won't affect gasoline and cars.

Extended data:

Preservation of ethanol gasoline.

Ethanol gasoline has very high environmental protection requirements, is very afraid of water and has a short shelf life. Therefore, the sales of ethanol gasoline are much stricter than ordinary gasoline in all aspects of preparation, storage, transportation and sales. Generally, small gas stations do not sell ethanol gasoline.

If the small gas station can't be sold within a month, or if it is added to the car and it is on a business trip, it will decompose and produce adverse reactions ... and eventually it will damage our car.

Ethanol gasoline is easy to delaminate after the expiration of the shelf life, and it is easy to become turbid in the fuel tank and can't catch fire.
