The 8th International 500-Mile Sweepstakes Race was held at the Indianapolis Motor Speedway on Monday, May 31, 1920.

Ralph DePalma held a two lap lead when the car stalled on lap 187. His riding mechanic Pete DePaolo ran to the pits to get a can of gasoline, thinking they were out of fuel. DePalma was able to get the car rolling again, and the two rejoined the race. However, during the delay, the lead went to Gaston Chevrolet. Chevrolet himself ran out of fuel on lap 197, but he was able to coast to the pits and refuel. Chevrolet held on to win. Seven months later, he was fatally injured in a crash at Beverly Hills.

Chevrolet won the race without a single tire change, a remarkable feat at the time. Chevrolet was accompanied by riding mechanic John Bresnahan. Chevrolet's victory was the last by a driver born outside of the United States until George Robson's victory in the 1946 running.

The 1912 Indianapolis 500-Mile Race, or International 500-Mile Sweepstakes Race, the second such race in history, was held at the Indianapolis Motor Speedway on Thursday, May 30, 1912. Indiana-born driver Joe Dawson won the race, leading only the final two laps. Ralph DePalma dominated the race, leading 196 of the 200 laps, and pulling out to an over 5-lap lead. But with just over two laps to go, his car failed with a broken connecting rod.

The 6th International 300-Mile Sweepstakes Race was the sixth running of the Indianapolis 500. It was held at the Indianapolis Motor Speedway on Tuesday, May 30, 1916.

Any fuel was allowed, which directly affected the race.

The 25th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway on Monday, May 31, 1937. With temperatures topping out at 92 °F (33 °C), it is one of the hottest days on record for the Indy 500.

The 22nd International 500-Mile Sweepstakes Race was held at the Indianapolis Motor Speedway on May 30, 1934. The winner was the number seven car driven by Bill Cummings, an Indianapolis native, at an average speed of 104.863 miles per hour. Cummings led for 57 laps total, including the last 26. Of the 33 cars that began the race, only 12 were running at the finish, although there were no crashes resulting in serious injuries. One serious incident involved George Bailey, whose car went over the outside wall, but resulted in only a broken wrist to the driver. The finish was the closest in the history of the race to that point, with second-place finisher Mauri Rose within 100 yards of Cummings at the finish. Rose would also file a protest that Cummings had illegally gained ground during a "slow-down" period following a crash.
