The weight of a 55-gallon drum of oil can vary depending on the type of oil being stored. However, on average, a 55-gallon drum filled with conventional motor oil weighs around 450 to 480 pounds (204 to 218 kg).
This variation in weight is largely due to the differing densities of various oils. For instance, lighter oils, such as some vegetable oils, may weigh less, while heavier oils, like heavy crude or some industrial oils, may weigh more. It’s important to consider these factors when calculating transportation or storage requirements.
Additionally, a standard 55-gallon drum itself typically weighs between 40 to 50 pounds (18 to 23 kg) when empty. So, the total weight, including the drum, would range from about 490 to 530 pounds (222 to 241 kg) when filled.
