The following graph shows US petroleum imports from OPEC countries starting in 1960. This includes both crude oil and petroleum products.
Note: Indonesia left OPEC in 2008 but it is included here because most of US imports happened before that year. Indonesia’s oil available for export peaked in 1977, US oil imports from Indonesia peaked one year later in 1978 and Indonesian oil consumption exceeded production since 2004.
Data are from the EIA’s Energy Review page (petroleum section):http://www.eia.gov/totalenergy/data/monthly/#petroleum
After the US peak in 1970 US imports from OPEC increased sharply until 1977 when Iranian oil production peaked and started to decline
