Sorry, but I've seen test data (from the source I've mentioned here
several times before - MCN) that shows the above statement to be
patently false. There was a wide range of data in virtually every
parameter of the oil that was tested.
Some oils have far better additive packages than others, and the
correlation wasn't perfect with price and brand name, but it was
significantly correlated.
Standards in most cases provide only a minimum (or ocasionally a maximum
to prevent catcon poisoning) requirement. They don't ensure equality at
all. The Air Force has a minium height standard for its pilots (and a
maximum as well). Do you you really think this standard means that all
pilots in the Air Force are the same height?
Ha, ha, ha. This is funnny.
