what kind of oil for new rebuild

I think it is time to put an end to the synthetic myths along with the term "slippery." Terms like viscosity index, TBN, centistokes, pour point, etc. are what we use to compare the properites of oil. If anyone wants to use the term slippery to describe an oil's performance, they shuold accompany those coments with values, numbers and test data to back it up, or they are just talking smak.
