A 1971 Ford Bronco's oil capacity depends on the engine it has. There were several different engines offered that year. You
must check your owner's manual or a reliable Ford Bronco parts website that specifies the year and engine to determine the correct amount.
Without knowing the engine size, I cannot give you a definitive answer. However, a common range for engines in that era is between 5 and 6 quarts. But again, this is not definitive. Always check the owner's manual for the precise amount.
