Like the 0w30 Duron so far. Cold start knock is noticable better, although not much. smooth at idle, just the colour. Much darker than anything I've run before. Suspect it's the add pack for a HDMO as opposed to PCMO (what I've run before). Comments..... PS: The steak I'm eat'n, I don't think it was properly bled out, **** that's a heavy steak.
