Motor Oil Bible

[Bengt_Phorqs]

While doing some research on different motor oil specifications I came across this reference included in "The Motor Oil Site".  I briefly mentioned the Motor Oil Bible in another thread a few days back.  I'm including it here not to create controversy, but if you find it useful then so much the better.
