Prix, the LC90. As at the previous race in Brazil, they finished first and second, with Éric Bernard nearly a second faster than his team-mate Aguri Suzuki. The updated Osella FA1ME of Olivier Grouillard was third fastest, a fraction ahead of Roberto Moreno in the EuroBrun. Apart from the AGS cars, the other runners who failed to pre-qualify included Bertrand Gachot in the Coloni, which, despite revised aerodynamics and a 23kg weight reduction, was still seven seconds away from Bernard's time. Even slower was Claudio Langes in the other EuroBrun, down in sixth place. At the Life team, Bruno Giacomelli drove the L190 for the first time, having replaced Gary Brabham. A drivebelt failed on the Italian's very slow first lap, and the car did not reappear for the rest of the session.

At Tamburello, Mansell ran wide and kicked up dust, which caused the Leyton House of Ivan Capelli and the second Tyrrell of Satoru Nakajima to collide with each other, while at Tosa Martin Donnelly spun his Lotus, narrowly avoiding other drivers. Meanwhile, Boutsen got past Berger but was unable to close on Senna. The order remained the same until lap 3 when Senna pulled off with a broken wheel rim, allowing Boutsen to take the lead with Berger close behind. Further back, Alesi collided with Piquet at Tosa; both drivers continued. Boutsen led until his Renault engine blew on lap 17, which left Berger ahead of Patrese and Mansell.
