Proper labeling of the viscosity grade on oil containers is well defined by the SAE, and in the NIST Handbook 130 which is codified into law in most states. Per NIST HB 130 from the PQIA website:
"One example is seen in Section IV. Uniform Regulations B. Uniform Regulation for the Method of Sale of Commodities in the NIST Handbook 130 (HB-130). This regulation states; “The label on any vehicle engine (motor) oil container, receptacle, dispenser, or storage tank, and any invoice or receipt from service on 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 letters “SAE” in accordance with SAE International’s latest version of SAE J300, Engine Oil Viscosity Classification.” "
Likewise in California code, again from PQIA:
"Another example of regulations pertaining to how the viscosity must appear on motor oil labels is seen in Chapter 14, Article 9 – Labeling [13480] (b), in California’s Business and Professional Code. The regulation states; “When the product is a lubricant, as defined by Section 13400, each sign or label shall also have in letters or numerals, plainly visible, the viscosity grade classification as determined in accordance with the SAE International latest standard for engine oil viscosity classification SAE J300 or manual transmission and axle lubricants viscosity classification SAE J306, as applicable, and shall be preceded by the letters ‘SAE’.” "

Are these QB oils with non-complying viscosity grades
available on retail shelves or only by special order from the blender?
