Mixing oil grades

[Jonff]

Currently got 10w40 engine oil in the engine at the moment but I've got 0w40 and 5w40 in the garage. Would I be able to top up with the 0w40 and 5w40 without causing problems?

Use as little of the 0w40 as possible, I believe 5w40 is recommended anyway.

I haven't got much left of either to be honest, just a case of using it rather than it just sitting there.

Yeah 5w40 is Renaults Recommended grade, although I've heard rumours that some of them don't use that grade themselves.

why? technically its safer when cold and exactly the same when hot
