Re Amsoil mfr. approvals:

If you read the Amsoil statement carefully they do not say that their
oil meets any of the approvals you mentioned. Amsoil does this a lot.
They have not subjected many of their oils to the engine mfrs. or an
approved lab for tetsing. I think what they are trying to say without
admitting the above is that their oil is an equivalent. However it
makes one wonder why they do not seek the required approval. As for
the discussion on dino v synthetics. There are applications where
synthetics have an advantage. The Canadian North is one. HD truck
trannies and difs is another. Road Ranger is able to give million
mile warranties on their transmissions due to the use of synthetics.
I have an article in one of my other computers that I will try to
find. Major oil company engineers are interviewed and the consensus
is that synthetics for HD diesel engines is a waste of $. Modern
engine oils are so advanced that they are almost synthetics. The
additive packages and the viscosity index improvers are light years
ahead of the oils of say 20 years ago. Many synthetics are actually
made from dino oil. It is simply the way they are refined. As far as
I know no major synthetic mfr. has a label that states this oil
contains no dino oil. I would like to know if any major transport
company uses synthetics? Schneider, UPS, Swift, Wal Mart??? These
companies are always loking for ways to reduce costs. If synthetics
provided an improvement they would be using that oil.
