Oil Reccomendation Anyone?

[s4-99]

Ok it's nearly that time again for servicing... I was wondering what oil you would reccomend or use yourself.....I've been told to get a 5w-40 fully synthetic....No probs but there is that many to choose from it can get confusing.....So my choices are:- Silkolene Pro S, Millers CFS, Motul 300V, Redline, thats the top end bracket....The ok ones are:- Motul 8100 X-Cess, Gulf Formula G, Fuchs Supersyn and Mobil Synt S.

If anybody has any others then feel free to confuse me even more

Forgot to mention, no track use but some serious road use occasionally 340+ bhp

Thanks.
