Like his team-mate Nakajima, Carlos Huertas made a good start to pick up places on the first lap, and then the Colombian held off a race-long challenge from Mexico's Esteban Gutierrez to claim fifth at the chequered flag.
Jazeman Jaafar took seventh for Carlin, ahead of Gabriel Dias, Adriano Buzaid and Rupert Svendsen-Cook, with British F3 debutant Alexander Sims 11th for ART and Hitech's Will Buller claiming the final championship point in 12th.
The National class was depleted by a third on the warm-up lap when Menasheh Idafar cannoned his T-Sport Dallara into the back of a stationary Felipe Nasr, the Brazilian's car having expired on the grid. Both cars were badly damaged but neither driver was hurt.
That left Idafar's team-mate James Cole to keep Motul Team West-Tec driver Luiz Razia behind him for the duration to claim his second class win of the season and increase his class points' lead.
Tomorrow's 20-minute 'sprint' race will see Calado start from eighth on the grid, with Dias on the pole, just as he was at Oulton Park.
