No need for sarcasm, Ron. You didn't mention anything about you doing a search. Over the months I have seen plenty of discussions with regards to D1 on this board, so my suggestion was to try and help you.
Well, I got some D-1 anyway.I'll run it this summer in my Ford E150 van for about 6k miles. Afterwards,I'd like to compare it to my Blackstone analysis on Syntec 5w50. Thanks Paul,no harm intended.
