How Many Kilograms is a Barrel of Engine Oil?

Different brands and models of engine oil have different densities, so the weight calculated per liter of oil also varies. One liter of engine oil is approximately 1.6 catties. Typically, the density of engine oil is 0.8g/ML, and one liter equals 1000ML. 1000ML * 0.8g/ML = 800g, and 800g = 1.6 catties. Of course, this is not an absolute value, as the density of engine oil can have an error of around 0.1L. Additionally, there are many types and brands of engine oil, and since oil is a liquid, the converted values can only be approximate. Precautions when adding engine oil: You must go to a regular gas station, such as Sinopec, PetroChina, or other reputable gas stations, as these not only offer competitive prices but also guarantee the quality of the gasoline. For a new car, it is recommended not to fill up the tank completely during the first refueling. Overfilling can easily cause issues with the fabric and sensors, leading to inaccurate fuel gauge readings. Remember to change the engine oil and transmission oil. If the oil is not changed in time, the car will not perform well. Avoid going to gas stations during stormy weather, as gas stations are flammable and explosive places. Lightning can easily conduct electricity, making refueling during storms very dangerous.
I've been driving for over twenty years and have lost count of how many times I've changed the engine oil myself. A standard 4-liter oil can weighs about 4.5 kg in total. Engine oil has a slightly lower density than water, approximately 0.85 grams per milliliter, so the net weight of 4 liters is around 3.4 kg. The plastic can is lightweight yet sturdy, usually weighing about 1 kg. Holding it in my hand feels light and effortless, though carrying two cans at once requires a bit more effort—be careful not to strain your back. Different brands might have slight variations in can weight, similar to the 1-gallon cans commonly used by American brands, with a total weight of 4 to 5 kg. When storing in the garage, avoid stacking them too high; plastic cans are pressure-resistant but can be hard to move when too heavy. One oil change typically uses exactly 4 liters, emptying one can to avoid leftover oil getting contaminated.
