O'Neill, who also scooped the same prize at Snetterton last year, was rewarded for his heroics in race three when he finished second.
David will also get the chance to savour a grid walk as part of the overall prize of winning.
Paul O'Neill, who now heads up the independent drivers' standings, said: "This season couldn't have started much better for me.
"Winning HiQ's champagne moment award last season was a personal highlight, and it is special to win another one now, so soon into the new season."
All spectators are invited to log onto HiQ's official website, http://www.hiqonline.co.uk/ to vote for their star performer from the next round of racing, at Brands Hatch on May 2nd.
The man that receives the most plaudits from the round of racing will be crowned with HiQ's Champagne Moment award and presented with a magnum of bubbly before the next race.
One lucky fan who has logged his or her details onto the website will be picked at random to present the prize to the driver and complimentary race tickets will also be provided, along with a grid walk of the track before one of the races.
HiQ's marketing manager Geraldine McGovern said: "Paul O'Neill is a particularly popular driver and a worthy winner. He has always received a lot of votes and he never seems to let his supporters down on the track. We wish him well at Brands Hatch, along with the rest of the field.
