How do you find how much your bulk oil tank holds?

To determine the capacity of your bulk oil tank, check for a label or manufacturer's specifications that typically indicate the tank's volume in gallons or liters. If this information is not available, measure the dimensions of the tank (height, width, and length) and use the formula for volume (for a rectangular tank: length x width x height). For cylindrical tanks, use the formula: π x radius² x height. Finally, convert the volume to your preferred unit if necessary.
