I was looking at tech Sheets on pennzoil.com at the new Pennzoil Full Synthetic (GF6) 0w20. 5w20 and 5w30. Every sheet had the same #s (pour point, Kinetic Vis etc..). So I called tech hotline and they said it is obviously an error and they would send to proper department to fix and give it a month.
