As this is my first post.... I do not want too highjack a thread, but it appears as this one has run it's course. So to add another weird oil story.
Back in the early 60s Harley Davidson had some ...bad oil... their name on the cans. Would cut the top off cans that would not pour, put your hand inside, and dip out a big jellied slug about the size of your fist.
We would take and throw it hard as we could up 20 feet to a wood ceiling and see who's slug would form a single string all the way to the floor!!!! Have no idea what the cause, or how wide spread this was. Remember this was the 60's.
