Sec. 79.33  Motor vehicle diesel fuel.

    (a) The following fuels commonly or commercially known or sold as 
motor vehicle diesel fuel are hereby individually designated:
    (1) Motor vehicle diesel fuel, grade 1-D;
    (2) Motor vehicle diesel fuel, grade 2-D.

The Act defines the term ``motor vehicle'' to mean any self-propelled

purposes, the fuel manufacturer shall furnish the data listed below. The 
highest, lowest, and average values of the listed characteristics/
properties are to be reported. For initial registration, data shall be 
given for any 3-month or longer period prior to the date of submission.
