Home Heating Oil Deliveries: Weights and Measures Inspectors inspect and test oil truck meters for compliance to commercial standards and accuracy of delivery.  The driver is required to leave a receipt printed by the delivery system.  Verify on the receipt that the meter started on zero gallons and shows the total gallons delivered.  Remember that the gauge on your home storage tank is not a calibrated indicator of actual delivered volume.  If you have questions or concerns about a delivery,contact your local weights and measures authority.
