We have at least 3 threads going on this. Go back to the other thread and I laid it out there. Hughes is wrong. Read what I posted over there.
BTW, I think it was the road kill dude and the long haired Chrysler guy who's name...Dulcich...did a test with the dude form Westech...I'm horrible with names..I can see the faces but can't think of the names...did a test on aluminum verse CI and they found nothing.
Just like I have been doing since 1980.
