McKinley died at his home in Dallas, Texas, a Chevron spokesman said.
Chevron acquired Texaco in 2001, more than a decade after Texaco filed for bankruptcy following a major lawsuit related to the McKinley-led company's attempt to acquire Getty Oil.
Texaco had offered to buy California-based Getty in 1984 for $10.1 billion, part of McKinley's attempt to invigorate Texaco. However, Texas-based Pennzoil claimed it had already agreed to buy Getty and sued Texaco for $15 billion in damages, according to news reports.
