de Oliveira quickest in second Macau practice.

Japanese F3 champion Joao Paolo de Oliveira led the way during an incident-filled second free practice session for the Macau Grand Prix, edging out Briton Mike Conway and Frenchman Loic Duval.

The Brazilian traded times at the top of the timesheets with several other drivers before eventually putting in his best effort with 16 minutes of the session remaining.

?EURoeIt is looking good,?EUR? he said, ?EURoeWe have made a few set-up changes since yesterday, and I am quite happy because my lap time without a tow is pretty close to what I could achieve with one. I also have got new tyres for this afternoon....?EUR?

de Oliveira?EUR(TM)s rivals?EUR(TM) hopes of beating his best time were eventually wrecked by three separate incidents, which brought out the red flag with five minutes remaining.

Christian Bakkerud spun backwards into the barriers at Dona Maria, before Steven Kane damaged the left rear corner of his car after clouting the tyre wall at Police. At almost the same time, Bruno Senna hit the barriers with the right-hand side of his car, leaving the organisers with no option but to halt proceedings. Stephen Jelley also touched the barriers at Lisboa during the session, but did not suffer any major damage.

Conway, however, continued to impress on his first visit to Macau, setting the second quickest time on only his second day in the Mercedes-powered Manor Motorsport Dallara.

?EURoeThat was good,?EUR? the former Formula Renault champion said, ?EURoeI slept on things last night and was able to do a good time today ?EUR" the speed is coming from me. I?EUR(TM)m quite optimistic for this afternoon because I should get more time from new tyres.?EUR?

Behind third-fastest Duval, provisional pole position man Robert Kubica admitted that he had taken it easy in the session.

?EURoeIt?EUR(TM)s only free practice, so there is no point taking any risks,?EUR? said the Carlin Motorsport driver, ?EURoeWe made a few changes to the car overnight and my tyres are clearly past their best, but we should be okay with new ones for qualifying.?EUR?

Franck Perera posted the fifth fastest time of the session on his return to action after a disappointing qualifying session, while Lucas di Grassi, provisionally second on the grid, Naoki Yokomizo, Dan Clarke, Charlie Kimball and Paolo Montin rounded out the top ten, the Italian birthday boy reporting no repeat of the gearbox problems that affected him in qualifying yesterday.
