I have a question regarding what engine oil viscosity i should use for my rs4 4.2
I have seen many reccomend 5w-30 but the topup oil i bought from audi after the previous service was 0w-30, Would Audi give me another oil viscosity than they just filled the car with?
I have heard that 0w-30 is better for cold climate, the car may be started in a few minus degrees celsius, but is that oil doing any less of a job in high temperatures? It will be ridden hard in summertimes with oil temperatures to about 120celsius.
Thanks for any replies!
