    Check the manual, I think it should be RN 0720.

    All ACEA Cx oils are designed to be compatible with DPF fitted diesels, with minor differences - like low SAPS, different viscosity and long-life requirements. As far as a fast Google can show, C4 is like C3 but with low SAPS contents.

    Get an oil with manufacturers approval, ACEA and SAE specs are more generic.

    RN 0720 5w30. Get it direct from renault. 40 euro all in for 5 litres. The RN 0710 5w40 would be better if you don't have a dpf but I think after 2010 or so they all have one.
    The 5w30 is c4 and the 5w40 is c3 afaik.

    If it's a 1.5dci then it will be euro 5 (euro 5 came out in early 2011) and have a dpf so you have to use RN0720 spec 5w30. As said probably as handy to get it in a dealer the only two brands I know of that make RN0720 oil are Fuchs or elf so don't bother looking at Castrol or Mobil as they don't make it.
