Oil recomendation?

I've stuck with the Elf 5W40 Synthetic, must be a reason why Renault reccomend it and it's not a cheap oil or budget brand by any sense of the word.

This is the website I got him to price match, bit more expensive than it was but still a decent saving: http://www.asptrading.co.uk/acatalog/MOTUL_.html#a813

Interesting read.
