Charles L. Binsted, 53, executive director of the National Council of Petroleum Retailers, died of cancer Friday at Sibley Memorial Hospital.

Mr. Binsted, who had owned and operated an Exxon service station at 4812 MacArthur Bivd. NW since 1946, was a lobbyist for legislation in behalf of the 200,000 independent gasoline dealers he represented. His greatest triumph came this year with the passage of the so called "Dealer Day in Court" legislation.

The law spells out the rights of gasoline station operators in dealings with their suppliers, including major oil companies.

Mr. Binsted, who was often at odds with the major oil companies and independent refiners, was warmly regarded by most members of the oil industry's diversified lobbying community.

His career in gasoline dealer association work began in 1950 when he joined the Greater Washington-Mary-land Service Station Association. He later was elected to the board of directors of the National Congress of Petroleum Retailers, and was named president in 1971.

Mr. Binsted was a member of the Energy Department's gasoline marketing advisory committee, and served on the American Petroleum Institute's consumer affairs committee. He also was a member of the Automotive Information Council and served on the board of the National Institute for Automotive Service Excellence.

Survivors include his wife, Mickey, of the home in Potomac, and two sons, Wayne, who manages the family service station, and Stanley, a civil engineer working in Saudi Arabia.
