I'm going to drop the oil in mine in the next couple of weeks. Just looking at Halfords website at Castrol edge......it doesn't say "professional" on it but it does show the right spec.......vw 507 00. Will the Halfords "Edge" be ok?Just make sure you get the correct one, think it's the pro long life one.. Can't remember at the moment, it's expensive, but if you run the wrong one you will stuff things up.. Oil is now part of the emissions system as well as lubrication..
