Now you are showing yourself as a total fool.
The 'good as any' snake oil you are promoting will void any
manufacturers warranty because it does not meet 'any' automotive
standards.
Someone once gave me a case of the 'spamsoil' crap because no one was
stupid enough to buy it from him, we 'like' our engines around here. I
trashed it at the recyclers for him...
That said there are very few 'real' synthetics on the market. The
makers went to court to get the definition of 'synthetic' changed so
they could slap the synthetic label on anything weaker than raw crude
oil that has been 'refined' and charge 4 times extra for the pretty
label.

I don't sell AmsOil. I have used their products, also Klotz and
Bel-Ray and others, for specific jobs, and they all worked as
advertised.
Aeroshell AD oil does not meet any automotive standards either but if
you are running a pushrod gasoline burning air coold engine it's
nevertheless the stuff to use.
You just have a hard one for Amsoil. The fact is that with specific
exceptions it works okay or better. And it's less expensive and more
available than specialist products like Bel-Ray or Klotz.
