I thought this was an easy one, I hear you guys talking Castrol Edge all the time, so went to buy some, and there are a number of variants:
Edge
Edge Professional
Edge Sport
Edge Longlife
I'm on yearly / 10k service intervals, so guess it's not longlife I need. But do I need the Professional one? VW Colbournes in Guildford say so, but I can only find it in 1L bottles, and I don't really trust them anyway! Is normal Edge ok? I'd really appreciate a quick answer, as I have a big service on Thursday.
