Why ethanol blended with petrol? Warning of the sellers!

The Tamil Nadu Petrol Dealers Association has warned consumers not to spill water in petrol tanks as 10% of ethanol-blended petrol is sold as petrol and diesel. After the price hikes, this notice makes more headache to the people.

A statement issued by the Tamil Nadu Petrol Dealers Association said, “Oil companies are currently distributing 10% ethanol in petrol as per the order of the Government of India in an effort to protect the environment.

Vehicle owners and drivers should regularly wash their vehicles with water to ensure that water does not leak into petrol storage tanks (tanks) even when it is raining.

A little water is enough to attract ethanol in petrol. This converts the ethanol of petrol in the vehicle’s storage tank into the water and stays at the bottom of the petrol tank. Therefore, it may be difficult to drive or jerk your vehicle while driving. ”


Ethanol, a by-product of cane juice obtained from sugar mills, is also used by factories and distilleries.

In a reply to the Lok Sabha in July 2019, Petroleum and Natural Gas Minister Dharmendra Pradhan said, “At present, PSUs are selling 10% ethanol blended petrol. According to the National Policy on Biofuels 2018 issued by the Federal Government on 08.06.2019, the target is to sell 20% ethanol blended petrol by 2030, ” reported.

For the past 10 years, the federal government has been trying to add ethanol to petrol at 5%. It was also difficult to bring into use due to its price. However, it is currently sold in ethanol blends at 10% of petrol.

Why Ethanol?

India is implementing the use of ethanol-blended in petrol as it needs to increase the use of biofuels to reduce the dependence on oil imports for petrol and diesel consumption.

At the beginning of 2019, only 5.6% of ethanol was used in gasoline. At present, it has risen to 10%. The federal government had proposed to increase this to 20% by 2030. However, it is said that information has been released that this is to be implemented before 2030.

report released by the Central Ministry of Road Transport and Highways in December 2020 said, “Petrol blended with 20% ethanol helps reduce emissions of carbon dioxide, including hydrocarbons. This will reduce the cost of oil imports, save foreign exchange and enhance energy security. ”

Ethanol fuel carbon dioxide emissions are lower than gasoline. Therefore, it is seen as more environmentally friendly than petrol and will help reduce oil imports.

However, ethanol is less efficient as a fuel. It produces one-third less energy than gasoline. The result is only higher fuel consumption and lower mileage. Older vehicles are said to be affected by high levels of ethanol in petrol.

Over the past few years, India has been making strides in ethanol fuel producing countries. Ethanol production is projected to reach 3 billion litres in 2019, 11 per cent (2.7 billion) more than the previous year, according to the Economic Times.

In the future, India will have to produce more ethanol fuel to blend 20% ethanol in petrol. Customers who no longer use petrol should be careful not to spill water on their vehicle’s petrol tanks.
