Sorry yeah, oil!
Mine has done 3650 miles and I was going to change the oil very soon. There have been a number of threads about this, one suggesting the same elf oil as you have.
To be honest I was going to use Mobil 1, an oil I have used in many of my cars but assuming some of these people on this forum know what they are talking about it appears that the elf oil could be a good option. My only concern is that this school of thought could be born out of lack of funds as opposed to it actually being the best oil.
Lets not forget that elf is only recommended due to Renaults relationship with them. I would never have used elf beforeand I very much doubt I will now so, Mobil 1 it is then.
Sorry about the waffle, how long have you had your Cup? Out of interest what were your previous cars, the Cup was my second Renault after a long line of BMWs, E30 M3 etc.
