Drivers' Championship leader, Ayrton Senna, ran out of fuel in the second McLaren-Honda on the final lap and was classified fourth.
Elsewhere Tom Walkinshaw had bought a 35% stake in the Benetton team, but the driver line-ups were unchanged from the previous race.
The Friday morning pre-qualifying session resulted in a return to the Dallara / Jordan lockout seen three times earlier in the season.
Riccardo Patrese was third, followed by Gerhard Berger, Alain Prost, Jean Alesi, Roberto Moreno, Nelson Piquet, Maurício Gugelmin, and Stefano Modena.
At the front it was all Mansell as the Englishman recorded his second win in succession, while rival Senna ran out of fuel on the last lap and he was classified fourth.
In terms of having to pre-qualify, Brabham would have needed their top car at least in 7th position to demote the Leyton House team, but neither Brundle nor Blundell finished the race (Brundle retired with a broken throttle and Mark Blundell retired with engine failure later in the race on lap 53).
