Received a 1963 World Book "Yearbook."
Under "Automotive" is a short article titled: "The New, Carefree Auto Age."
According to the article:
"The new cars of today are built to last longer with less frequent attention than ever before. They are guaranteed against manufacturing defects for periods ranging from 24 months to five years. Before the fall of 1960, the maximum warranty was only 90 days.
"The average car is driven 120,000 miles or more and kept in operation 11 years before being junked.
"Oil changes have been reduced from once every 1,000 miles to every 4,000 miles or more. Ford recommended 6,000 miles between changes for it's 1963 models. Improved engine design eliminating areas of extremely high temperatures that tended to dilute the lubricants made the less frequent changes possible, the auto makers said. Oil companies however, remained reluctant to accept the less frequent changes. The American Petroleum Institute still recommended replacing oil at least every 60 days in summer and 30 days in winter.
"Anti-freeze protection for two years is provided by American Motors and Ford. Each installs radiator coolant at the factory. Such products found little demand in the replacement market however, and were withdraw after two seasons."
