I would like to share my opinion with you on this, but I cannot use profanity on this website. I am going to check into this, but I will tell you what the tech sheets on the Pennzoil website tells me. It tells me that a good Group II+ works as good as a Group II - III blend. Same vis at 100c and the regular dino Group II+ has a better pour point. I was told the blend has a better AW package and I will let you know. Man oh man, how is someone supose to figure this stuff out. ![[Duh!]](/forums/graemlins/pat.gif)
