Engine oil tanks, that is, engine oil tanks on the market are made of iron/aluminum materials, collectively referred to as engine oil tanks. Engine oil tanks are not easy to be imitated, and fakes are relatively not as high as ordinary plastic engine oil. Because engine oil is corrosive, for organic matter, iron cans are less corrosive, so the oil is packed in iron tanks and the oil purity is high some. Putting it in a plastic bucket will corrode the plastic, and it will burn when added to the engine. The iron canned motor oil is for the purpose of preventing the oil from being re-used and eliminating imitations and the purity of the oil.
