What they've actually sent is this...

It doesn't specifically state "Stop Start" on it, but does state C2. Also on the back it states "ACEA C2; PSA Approval B71 2312".
The Castrol website after searching with my reg no shows the one I've received as recommended, and the one I ordered as the alternative.
Any reason to worry or not? I'm guessing it's OK, it's possible they're just updating the packaging as Stop-Start is no longer a novelty?
Does the PSA Approval code include the capability of using in a Stop-Start engine, or is it an optional extra?
Many thanks.
