Dude I responded to your post! Bummer that it didn't rank! "DG, I think the reason why "oil experts have not chimed in" is because nobody knows the details. They can chime all day long and get it wrong and therefore loose credibility. I think the oil experts on this board did the exact thing that experts usually do, say nothing until more details are known. Cheers
