The topic I am going to discuss with you now is how to fill a big drum with oil from an oil tank truck. The mass drums are kept next to it. The oil in this drum will be sold at wholesale prices. This shop is located in the big oil market in our area. People buy oil from here to sell it. That oil is then sold at retail prices in the retail market. These oil trucks have been brought from Dhaka at the highest wholesale price.
