Oscar has been competing for the past three seasons, but this is the first time he's completed all six races in the series - including Hampton Downs, Manfeild, Taupo and Pukekohe tracks - in his 1994 Toyota MR2 as Team DPR.
He lists his motorsport heroes as V8 driver Scott McLaughlin and rally driver Haydon Paddon and he will always be impressed by the skills of Greg Murphy and hopes one day to emulate some of their success.
Oscar said he first got interested in motorsport as a 4-year-old, when he said he wanted to be a V8 Supercar driver, then aged 8 he got into go-karting.
"I did okay at that, but all my mates moved on to bigger stuff like speedway. But it's expensive and we couldn't really afford to go on to anything like that and the 2K Cup came along and was perfect for us," he said.
"It's quite a cheap motorsport to get into and very competitive. But it's also a lot of fun with the other racers basically like a big family, they are all so good to each other and friendly."
Oscar would still be keen for a spot in V8s, but realises that as he gets older if he does not get a sponsor it's an unrealistic dream.
So the youngster hopes his efforts in the 2K Cup will put him in the shop window.
"For me it's about getting as much racing experience as I can and if I can get some more success then hopefully somebody will see something in me and give me a go," Oscar said.
"We can't really afford for me to step up unless I get a serious sponsor so it's about me putting in the hard yards and hopefully I get noticed."
