Slowly slowly people will come to realise that ulx-110(Green/blue coloured oil) is one of the best oils. The trend is starting for form, not only with our holdens but with Jap imports which only used to push full synthetics. On independant dynos (can be found on net - ulx site and planet soarer site) that as a full mineral oil it beat Mobil 1 Full synthetic or at least equalled the mobil, but never less.Also very good is the Brad Penns 'The Green Oil'(Has a colour indicator of when to change it). Both mineral oils and used in racing overseas in the states. Finding that it outlasts and less repairs on their vehicles during the season. Valvoline Dura blend and valvoline in general are an excellent oil, for some reason they get bad press, maybe cause of their advertising, but there product is nowhere near like that Castrol stuff. I know its unbelievable but Valvoline Durablend being a Semi Synthetic has more synthetic in it that Castrol Edge (fake) full synthetic. Couple hours research and checking M.S.D.S (Safety data sheets) will reveal this and with many other apparent synthetics. Legally they are allowed to call in synthetic, so we call it synthetic.
But again, for price and money you cant go past the Penzzoil GT Street Machine. Like i said in answer to the original question from a 5.0 owner, this oil is made for his car, and being a VL- 20W-50 is probably the better weight.
