Funny you ask this, I'll be doing my half service oil drop in 1000km or so, easy to do at home.
I've got/used Castrol 5w-30 and 5w-40 which I think is 502. Tbh it doesn't really matter if your changing it every 7.5k.
Try and buy the 6L version as the capacity is about 5.7L, some up on special every few months at SCA/Repco etc.
I even bought the oil drain tool as I was damaging the plastic drain plug to much for my liking.
