quote:Not just any SLX 0w-30. As Losiho mentioned, there are many different versions of SLX 0w-30 in Europe and in the world. The one that the US guys call the original green GC was the "Castrol SLX Formula". However, now the GC in the US turned to gold (amber), and we really don't know for sure which version of SLX this is. Some rough VOA comparison would suggest that the gold GC is "Castrol SLX LongTec" in Europe, but no one has done any more in-depth analysis to confirm that. "Castrol SLX Longlife" is most definitely not the same as GC. There are also several "Castrol SLX" versions for specific automakers (GM, BMW, Volvo). These are probably not the same as GC either. So, if you want the original GC, look for "Castrol SLX Formula". It'll probably say "Made in EU" on the label.
