1.8 16v F7P engine oil choices should be in the handbook (if you have one).
10w40 or 5w40 should both be fine.
I liked the 5w40 Elf Excellium from the Renault Dealers - I think I paid about £20-£25 for 5 litres.
(But I think Renault have now switched from Elf to Castrol??)
Don't use Magnatec oil - it makes the engine sound like a bag of spanners
