I think I have used Vantage - almost got some at repco last month when it was out cheap but got more ultraclean at SCA instead.
I have got a variety of different oils here - 20w50 GTX, 10w40 magnatec, 15w40 gulf western, 15w40 Nulon, 10w30 Valvoline, 15w40 castrol ultraclean, dregs 15w40 gtx modern engine, penrite sae30, B&S sae30, magnatec 10w30 and another one somewhere I can't remember what it is
I change oil regularly and restock when on special - think there are somewhere around 6 bottles of ultraclean around here - $44 regular price but have never paid more than $22 for a bottle.
The Nulon and G Western are for flushing once or twice before the good stuff goes in
