The Commerce Department’s National Institute of Standards and Technology made uniform recommendations for motor oil information on invoices. These uniform standards mandate that the SAE oil ratings, brand, and weight are to be placed on a customer’s invoice.
Twenty states automatically adopted the standards. Others do so by Administrative Regulation. These standards became effective July 1, 2013 for states that approve, and are outlined in a section known as the Uniform Regulation for the Method of Sale for Commodities.
Here are the specifics:
“2.33.1. Labeling of Vehicle Engine (Motor) Oil.” – Vehicle engine (motor) oil shall be labeled.
“18.104.22.168. Viscosity. – The label on any vehicle engine (motor) oil container, receptacle, dispenser, or storage tank, and any invoice or receipt from service to an engine that includes the installation of vehicle engine (motor) oil dispensed from a receptacle, dispenser, or storage tank, shall contain the viscosity grade classification preceded by the letter ‘SAE’ in accordance with SAE International’s latest version of SAE J300, ‘Engine Oil Viscosity Classification.’”
