Why full synthetic oil?

[HBB]

As above. Renault specialist garage my cups due to get serviced at claim that semi-synthetic is just as good. Therefore why do you all recommend fully?

Search for a really good thread by Oilman, that will answer this question.

Silkolene Pro S 5w-40

EDIT:

Where's cheapest for silkolene? Enough to do a change. Does £40 sound reasonable enough?
