Castrol have just launched a new range of oils in the UK called Castrol Egde. Castrol Edge As best I can tell, this is just a rebranding of existing oils with a few minor tweeks. For example Edge 0W-30 appears to be the same as SLX Longtec (aka Gold GC) but now SM rated. The only 'new' oil is the 5W-30 which meets the new VW504 & 507 standards. I find it interesting that there are two 10W-60 oils listed, one specifically for BMW 'M' cars.
