G SPECIAL NOT5 REGARDING AUTOMOBILE GASOLINES
Certain automobile gasoline may now be lawfully used
in specific engines (Continental 0-200-A) in Cessna
150 aircraft if a supplemental type certificate is
first obtained from FAA, and if minor ad]ustments are
made in the aircraft's engine None of the current
fueling publications addresses this new development
Pending this action, automobile gasoline brought onto
an airport for use in any aircraft shall be stored/
delivered in/from the same types of equipment, using
the same procedures as for the various grades of
avgas API Bulletin 1542 prescribes no acronym or
color coding Until agreement is reached in the
industry and is published, automobile gasolines
brought onto the airport for use in aircraft shall be
identified by their full names or by the acronym
"mogas", followed by specific description as to
grade/type and octane rating, e g "Mogas-Leaded
Regular (89 oGtane)", "Mogas-Unleaded Regular (87
octane)", "Mogas-Unleaded Premium (91 octane)" Where
color coding or color banding would normally be used
to identify a specific aviation fuel, no color coding
will be used for mogas, in its place, the generic
acronym "mogas" will be boldly affixed using
paint/material which clearly contrasts with the
surface of the pipe/valve/tank/vehicle being used
PAGE 11
PART II
That if any sectlon~ subsection, paragraph, sentence, clause,
phrase or word in this ordinance, or application thereof to any
person or circumstance is held invalid by any court of competent
jurisdiction, such holding shall not affect the validity of the
remaining portions of this ordinance, and the City Council of
the C~ty of Denton, Texas, hereby declares it would have enacted
such remaining portions despite any such ~nval~d~ty
PART III
That this ordinance shall be in full force and effect immedi-
ately after 1ts passage and approval
